Lead Systems Engineer - VLEO Satellite Platform

Your mission Location:  Remote-first, with regular on-site visits to Nigrán, Spain Employment type: Full-time, permanent employee You will be the technical owner of Kreios Space’s VLEO satellite platform - the person responsible for turning mission needs into a coherent, buildable, testable and reliable spacecraft system. This is a senior technical leadership position with real engineering authority. You will define the platform direction, connect the different engineering domains and help the team make the decisions required to move from architecture to integrated hardware. It is not a coordination-only role. We are looking for someone who can operate at system level while remaining close enough to the engineering detail to troubleshoot problems, challenge assumptions and support the team when reality meets hardware. Own the technical direction of the platform Define and drive the satellite platform architecture, system requirements, interfaces, technical budgets and engineering margins, ensuring a coherent end-to-end design. Make the key engineering decisions Lead technical trade-offs across mass, power, thermal, communications, data handling, reliability and performance to converge on a platform the team can build, test and operate. Take the platform from architecture to hardware Define the system-level verification and validation approach and actively support integration, AIT and test campaigns, including test planning, procedures, acceptance criteria, anomaly resolution and reporting. Be the go-to technical problem solver Investigate system-level anomalies, identify root causes, unblock engineering teams and drive technical issues to closure using sound and pragmatic engineering judgement. Connect specialists into one system Align subsystem and domain experts across structures, avionics, ADCS, thermal, propulsion, software, FDIR and operations, ensuring that interfaces, assumptions and technical decisions remain consistent and properly documented. Establish strong systems engineering practices Build the structure required to manage requirements, interfaces, configuration, technical risks, design baselines, change control and engineering reviews as the programme evolves. Drive technical execution alongside programme leadership You will work closely with the Project Manager responsible for delivering Kreios Space’s VLEO satellite platform, aligning technical priorities with programme planning, milestones and delivery needs. You will also act as a key technical counterpart to the COO, providing visibility on platform progress, risks and critical decisions, and helping translate company and programme priorities into engineering execution. This will place you at the centre of the platform’s development, combining day-to-day technical ownership of the system with direct involvement in the strategic decisions that shape the programme.
