Systems Engineer - Space

About this role

Who we are Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards. As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously. We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers.

We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications. The role You will do the analysis and ship the code, turning mission and spacecraft design problems into the models, tools, and trade studies the constellation programme runs on.

You will also act as a technical expert on satellite and mission design, challenging partner and supplier designs alongside your own analysis work. The work culminates in moving a programme through development stages up to flight. The day-to-day Run mission analysis for constellation design, for example orbit selection, revisit and coverage, or launch and disposal. Own requirements flowdown, system budgets (mass, power, link), and the interfaces between segments.

Build and maintain the analysis tooling the rest of the team relies on, to production standards. Act as the technical expert for satellite system design, including subsystems. Drive trade studies across subsystems and segments. Present the results to internal teams, partners, and the customer. You should apply if you A master's or PhD in aerospace engineering, physics, or a related field, with hands-on work on at least one flown or near-flight space programme.

Fluency in orbit mechanics and mission analysis, with tools such as GMAT, FreeFlyer, STK, or Orekit. You can work from first principles where no tool exists. A working grasp of spacecraft systems engineering across requirements, budgets, interfaces, and verification. Recognised depth in at least one subsystem, for example AOCS and GNC, propulsion, power, thermal, or TT&C and RF. Several years of production-grade software work in a large, shared codebase, with code review, continuous integration, testing, and documentation.
