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 rolework 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 & traceabilitySystem architecture & interface management (ICDs)V&V; / test logic (procedures, reports, anomaly tracking)Risk & reliability methods and engineering marginsSpace 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 haveMBSE / 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.
