About this role

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.
