Space Subsystem Engineer
Pubblicato il 30-08-2026 - Finis Terrae in Roma
Company Overview
Finis Terrae is an Italian space company developing VERTUE, a green Orbital Propulsion Module for constellation deployment, in-orbit servicing, refuelling and cislunar missions. It runs on technology that does not exist together anywhere else: a throttleable bi-propellant engine fed by electric pumps, green propellants, a composite toroidal tank and a micro-acceleration device for propellant management in microgravity — for a structural efficiency up to 60% better than current competitors.
Building it means designing pumps, valves and actuators that have to work, once, perfectly, after months in orbit. That is the job.
The role
You will own mechanical and fluidic subsystems of VERTUE — mechanisms above all: electric pumps, valves, actuators, moving assemblies — from concept to qualification, working directly with the CTO.
- Define subsystem architecture, requirements, interfaces and verification strategy.
- Design and draft in CAD (SolidWorks, CATIA), through to drawings released to manufacturing.
- Implement "Design for Manufacturing" practices onto the baseliner configuration of the product.
- Run the analyses that justify the design: FEA (Ansys Mechanical / Abaqus) and CFD (Ansys Fluent / OpenFOAM).
- Verify against launch and orbital environments: loads, vibration and shock, torque and power margins, vacuum tribology, bearings, sealing.
- Apply ECSS and applicable design codes, and produce the documentation behind PDR, CDR, TRR and QR.
- Specify and follow hardware with suppliers, and plan and support qualification test campaigns.
What we are looking for
- MSc in Mechanical or Aerospace Engineering, strong academic record.
- Around 3+ years of relevant experience — not an entry-level role. Someone who has designed real hardware, seen it tested, and is ready for far more ownership than their current role allows.
- Experience with mechanisms for space or other high-reliability applications: pumps, valves, actuators, deployment or separation sys
