EGT, NGT or JPP? ESA has published a guide to choosing the right start to a career in the space sector
The European Space Agency, better known as ESA, published a guide on 16 April 2026 that seeks to clarify one of the more common dilemmas among young candidates interested in working in the European space sector: which programme is the right choice for their profile. The reason is very practical. During the year, several calls open for entry-level and early-career positions, and the differences between the programmes may at first glance seem small, although in reality they are crucial in determining who can apply, for how long, and with what professional expectations. ESA therefore puts three programmes at the centre: the ESA Graduate Trainee Programme, or EGT, the National Graduate Trainee Programmes, or NGT, and the Junior Professional Programme, abbreviated JPP. Each of them is designed for a different group of candidates, and an incorrect assessment of experience or status may mean that a person applies for a programme that actually does not suit them.
For those who follow European institutions and the labour market in science and high-technology sectors, this announcement comes at a time when interest in the space industry is growing not only among engineers, but also among experts in information technology, natural sciences, business functions, project management and analytics. On its official pages, ESA emphasises that it employs scientists, engineers and business professionals from all over Europe, and the initial programmes are often the first serious entry into that system. Because of this, the difference between a traineeship programme for freshly graduated candidates and a structured career programme for people with two or three years of experience is not an administrative detail, but a fundamental determinant of a professional path.
Three programmes, but three different starting points
In the briefest terms, EGT is the classic entry point for recent graduates, NGT is a similar model but with national funding and specific eligibility rules, while JPP is intended for candidates who already have relevant professional experience after graduation and want longer-term development within the agency itself. In the published explanation, ESA explicitly warns that understanding these differences is important so that candidates are directed to vacancies that truly match their background. This is especially important in 2026 because part of the NGT calls overlaps in time with the opening of the JPP selection, so candidates who read the conditions superficially could easily overlook key differences in experience, citizenship or type of contract.
Such a division is not accidental. Through entry programmes, ESA is simultaneously trying to address several needs: attract top young graduates, enable member states to have additional channels for involving their candidates, and build a pool of experts who can take on more responsible tasks and remain within the organisation for a longer period. That is precisely why the same title, “starting a career at ESA”, in practice covers programmes that differ in duration, the expected level of independence and the long-term employment perspective.
EGT: the main entry point for recent graduates
The ESA Graduate Trainee Programme is the best known and longest-running route for young candidates. According to ESA’s official data, this programme has existed for more than forty years, and the first participants started as early as February 1985. The agency itself states that this is a programme that enables recent graduates to gain valuable hands-on experience in the development and operations of space missions in an international and multicultural environment. In other words, EGT is not conceived as a symbolic internship, but as a concrete professional engagement on real projects.
The eligibility requirements for EGT are relatively clear. A candidate must be in the final year of a master’s degree programme or within one year of completing a relevant study programme at master’s level. ESA states that people from the fields of engineering, science, information technology and business services may apply, and the degree must be completed no later than within three months of the start of work. The programme is therefore aimed at those who are just leaving university or have just done so. Professional experience must not exceed approximately one year, which also aligns with the message of the guide published on 16 April 2026, in which ESA describes EGT as the “classic entry point” for graduates ready for their first major professional step.
One of the important practical pieces of information concerns the timing of the publication of calls. On its official pages and in FAQ documents, ESA states that EGT calls are published every year in February. As a rule, this is a large wave of opportunities: ESA states that around one hundred EGT positions are published every year across different disciplines. This means that candidates targeting this programme should not wait until spring or summer to start preparing their documentation. If they want to compete on time, their profile on the official portal, curriculum vitae and motivation letter must be ready earlier, ideally before the start of the annual publication cycle.
The duration of EGT is also important for understanding its nature. ESA states that it is a one-year contract with the possibility of extension for a second year. This shows that EGT is not intended as an automatic entry into permanent employment, but rather as a strong initial stepping stone. For many candidates, that is also an advantage: they can gain experience within ESA itself, become familiar with work on space projects and then more easily compete for further positions within the agency, research institutions or the European space industry.
NGT: a similar model, but with a decisive national component
At first glance, the National Graduate Trainee Programmes may look almost the same as EGT. ESA itself states that NGT resembles the EGT programme in most respects. But the difference is decisive: NGT positions are funded by individual countries through bilateral agreements with ESA, so eligibility depends not only on education and level of experience, but also on who sponsors the specific position. That is precisely the most important point that candidates often need to understand before applying.
On its official pages, ESA explains that NGT programmes offer final-year master’s students or people who have just graduated an opportunity for practical work in various space disciplines, from space science and Earth observation to telecommunications, navigation, mission control and human spaceflight. As with EGT, this is work under mentorship and with involvement in concrete projects, and the duration is one year with the possibility of extension to a second year. In terms of work content, therefore, NGT really is very close to EGT.
What makes NGT different is the framework of funding and the national right of access. ESA states that all member states, associate members and cooperating states can sponsor national trainee positions, but that does not mean they will all open them at the same time or to the same extent. The guide published on 16 April 2026 further clarifies that positions are open to citizens and permanent residents of the sponsor country, whereby permanent residents must hold the citizenship of an ESA member state, an associate member, a European cooperating state or Canada. In practice, this means that a candidate may meet all academic requirements, yet still not be eligible for a particular NGT if their country does not fund that position or if they do not belong to the circle of citizenships stated in the call.
For 2026, ESA especially highlighted that the first NGT calls will open in April and May, that is, in a period that overlaps with the start of the JPP selection. This information is important for two reasons. First, it shows that NGT is not necessarily tied to one single fixed annual date, but may open during the year, depending on agreements and funding. Second, candidates who already have some experience could find themselves in doubt between NGT and JPP, even though these programmes are not the same. ESA therefore rightly stresses that in 2026 detailed reading of the conditions will not be a formality, but a necessity.
JPP: for those who have already passed the first step
The Junior Professional Programme stands on the other side of the entry spectrum. ESA does not describe it as a traineeship, but as an entry career programme for candidates who already have relevant professional experience after graduation. That is perhaps the most important sentence for everyone considering applying. Someone who has just completed their studies and has no real work experience is not the profile for JPP. Someone who, however, already has two to three years of work behind them and wants more structured, longer-term development within the agency enters precisely the group for whom JPP is intended.
According to ESA’s official data, JPP is open to candidates with a relevant master’s-level degree and two to three years of professional experience. The agency further clarifies that time spent in some of its earlier entry programmes, such as EGT, NGT or the Research Fellowship programme, can count toward the required experience. This is an important detail because it shows that ESA views its entry programmes as a connected career system, not as isolated calls. A candidate who has already completed one early programme may, with sufficient total experience, be a logical candidate for JPP.
The difference is also visible in the type of contract. While EGT and NGT are one-year engagements with the possibility of extension to a second year, JPP brings a four-year contract at A1 level, with the prospect of moving to an indefinite contract after completion of the programme. ESA emphasises that the programme includes mentoring, a tailored development plan, rotations and additional opportunities to gain broader organisational and sectoral competences. In other words, JPP is not just a “slightly more serious traineeship”, but a mechanism through which the agency builds future professionals for longer-term roles.
ESA also states that from 2025 onward, 15 JPP positions are planned to be published every year. Numerically, this is significantly fewer than EGT opportunities, of which there are around one hundred annually, so it is clear that this is a more selective programme. In practice, this means that JPP candidates must demonstrate the relevance of their previous work even more precisely, because they are not competing only as “young talents”, but as people who must already show a certain professional maturity and readiness for greater responsibility.
When each call opens and why timing matters
One of the more useful parts of ESA’s guide concerns the publication calendar. Although the agency notes that exact dates may vary from year to year, the typical pattern looks like this: EGT is generally published in February, JPP in April or May, while NGT may appear during the year, depending on national sponsorships and individual open positions. For candidates, this means that the application strategy should not be one-off, but planned.
Timing is also important because of the preparation of documentation. ESA handles all applications through its official recruitment portal, and candidates there need to create a profile, upload a curriculum vitae and motivation letter, and track the status of applications. The agency also recommends activating notifications about new calls. This is especially important because candidates often focus only on the very moment the call is published and neglect the fact that a quality application is the result of earlier preparation, adaptation of documentation and understanding of the requested profile. In a competitive environment, a delay of a few days or generic application materials can make a noticeable difference.
In the case of 2026, additional sensitivity arises from the overlap of JPP and part of the NGT calls in April and May. Someone who has two years of experience after a master’s degree could formally target JPP, but at the same time notice an NGT position for the country of which they are a citizen. In such a situation, the details become decisive: does the call require experience, what is the contractual framework, is there a national limitation, what is the career potential of the programme and how much does the candidate want a long-term connection with ESA already at this stage of their career.
Which programme is realistically the most suitable for whom
If ESA’s guide were reduced to the practical question “what is best for me”, the answer can be formulated quite clearly. EGT is the logical choice for people who are completing a master’s degree or have recently completed it and have little or no professional experience. This is a programme for the first serious entry into ESA’s working environment, with a focus on learning through concrete projects and gaining operational experience. A candidate who is still finding their way, but has a solid professional foundation and motivation to work in the space sector, most likely belongs precisely to that group.
NGT is suitable for a very similar candidate profile, but only if there is a corresponding nationally sponsored position for which the person meets the citizenship or residency conditions. That is why NGT should not be viewed as a “backup option” to EGT, but as a separate channel that can be excellent, yet depends on the decisions of individual countries and the specific structure of the call. In some cases, it is precisely NGT that can open the door to a candidate who wants to work at ESA, but where the opportunity is tied to the national interest or financial arrangement of a particular country.
JPP, by contrast, is a programme for candidates who have already moved beyond the purely trainee phase. These are people with two to three years of experience after graduation who are not looking only for their first major work experience, but are targeting a development path within the institution itself. For them, ESA offers a four-year framework, mentoring, rotations and the possibility of a longer-term stay. That is precisely why JPP requires a higher degree of professional readiness: the candidate is no longer only a promising graduate, but a professional at the start of a more serious career.
The broader picture: ESA does not offer only one entry into the space sector
Although EGT, NGT and JPP are in focus in the current guide, ESA simultaneously reminds readers that these are not the only options for young talents and researchers. On the official pages about entry-level and research programmes, student internships, research fellowships, co-funded research models and Research Fellowship programmes are also listed for profiles that are academically or professionally closer to research work after a doctorate. This broader offer shows that ESA is trying to build several entry channels, depending on whether a candidate comes from the student, graduate, research or early professional stage.
This is also important for countries such as Croatia, whose candidates are increasingly following European calls in the STEM field. Although eligibility itself depends on the specific programme and the rules published in each individual call, the fact that ESA clearly segments programmes can help candidates assess their own position more realistically. In practice, it is often more useful to choose a programme that matches the real degree of experience than to try to “skip” a level and apply for a more attractive but less suitable model. That is precisely why ESA’s guide has greater value than an ordinary promotional announcement: it is also a reminder that a good application begins with an accurate understanding of one’s own profile.
In the end, ESA’s most important message remains quite simple. The path towards working in the European space sector does not necessarily begin with the most prestigious or longest programme, but with the one that most accurately matches the candidate’s previous education, experience and professional ambitions. In 2026, when some deadlines and announcements are drawing closer together or overlapping in time, precisely that assessment will be crucial for those who want to make use of the open door towards one of Europe’s most recognisable scientific and technological institutions.
