You will be the technical owner of our satellite platform- the person who turns mission needs into a buildable, testable and reliable system , and who is not afraid to go hands-on when reality hits hardware.

- Own the platform technical direction: define and drive the system architecture, requirements, interfaces and budgets to ensure a coherent end-to-end platform.
- Make the right engineering calls: lead trade-offs across mass, power, thermal, data, RF and reliability to converge on a design the team can actually deliver.
- Bring systems to the lab: define the verification approach and actively support AIT and test campaigns (planning, procedures, acceptance criteria, reports).
- Be the “go-to” technical problem solver: troubleshoot anomalies, unblock the team, and push issues to closure with pragmatic engineering judgement.
- Connect specialists into one system: align subsystem/domain experts across departments, ensuring interfaces, assumptions and decisions are consistent and documented.
- Enable execution with structure: work with a Project Manager who supports planning and delivery tracking, so you can focus on technical leadership and hands-on execution.

On-site role

work from our facilities in Porto do Molle (Nigrán, Spain), close to the hardware, the lab and the engineering team.

- Engineering degree in Aerospace / Industrial / Telecommunications / Electronics (or similar).
- 7+ years in space systems engineering , with participation in flight projects .
- Proven hands-on experience in system/subsystem integration and verification (AIT) .
- Strong background in:
- Requirements engineering & traceability
- System architecture & interface management (ICDs)
- V&V; / test logic (procedures, reports, anomaly tracking)
- Risk & reliability methods and engineering margins
- Space standards (ECSS or equivalent)

- Comfortable working across structures, avionics, ADCS, thermal, propulsion, SW/FDIR and operations .
- Mindset/skills:



technical leadership, autonomy, clear communication, prioritization, ability to move from high-level architecture to detailed problem solving.

Nice to have

- MBSE / SysML and architecture tools.
- Exposure to EGSE/MGSE , TVAC/vibration , EMC/EMI campaigns.
- Experience with avionics/electrical interfaces, harnessing, C&DH;, or on-board SW verification.
- Strong configuration/documentation discipline (baselines, change control, review packages).

At Kreios Space, we’re not just building technology- we’re redefining propulsion in orbit.
This is a place for people who want to push boundaries, challenge conventions, and work on problems that have never been solved before. We operate at the intersection of cutting-edge physics, aerospace engineering, and real-world impact- where your work doesn’t stay on paper, it flies.

What makes us different:

- Real impact, real ownership: You won’t be a small cog in a large machine. Here, you’ll take full ownership of critical systems and see your work move from concept to space. Decisions are fast, responsibility is real, and your contribution is visible.
- Deep-tech challenges at the frontier: We’re tackling problems that only a handful of teams in the world are attempting. This means high intellectual rigor, constant learning, and the opportunity to work alongside exceptional engineers and scientists.
- Top-tier talent, low ego culture: We’re building a team of ambitious, high-performing people who care deeply about what they do- but who also value collaboration, humility, and clarity of thinking.
- A company on a mission, not just a roadmap: Kreios is not optimizing an existing solution- we are creating a new category in space propulsion. Joining now means shaping the technology, the culture, and the future of the company.
- Growth that matches your ambition: As we scale, so will your scope. This is the right place if you want your career trajectory to be as bold as the problems you’re solving.
