Orbex has an exciting opportunity for a Principal Mechanical Engineer to act as a Technical Authority for the structural development and analysis of our launch vehicle, Orbex Prime.
You will take significant responsibility for flight structure development projects across technical performance, schedule and costs, taking a proactive role in the project from concept to manufacturing and launching flight hardware. For this role, experience in the design and analysis of finely toleranced flight structures for the space industry and/or composite structures would be extremely desirable, in particular Composite failure mode analysis and Launch vibration environments.

• Ownership of System and derived structures requirements: functional, general interfaces, LV environment, Operational (lifecycle, lifetime), physical, DFMEA (Design key characteristics), applicable standards (derived from SEMP and/or ECSS), mechanical dimensioning & test specifications.
• Coordination of Mechanical Engineering Team, from design concept up to maturation/convergence with design and manufacturing, planning the activities and managing the priorities/risks
• Ownership mechanical/thermal analysis to justify the adequacy of the designs.
• Leadership, training & mentoring of the analysis team.
• Ownership of the verification control document, used to ensure the compliance status of the structures requirements and support to change control process.
• Build-up and execute the development plan in coordination with the Composite Chief engineer: element testing, sub-component testing.
• Test Engineering authority for execution of the scale 1 mechanical testing (structural qualification in static, dynamic, shock): qualification test plans, test procedures, test reports, test results analysis. Owning the development of the Structures Department Testing capability.
• Support to the Quality Gates: PDR, CDR, QR. Ownership of the documentation containing the dimensioning load cases, thermal/mechanical analysis, design justification files, qualification test plans, test results analysis, fly worthiness/qualification certificate files.
• Support as technical authority for validation of manufacturing & assembly measurements, NCR treatments.
• Support to System in built-up of MCI model, LV aero analysis, LV structural analysis, Integrated Structure/thermal models
