An innovative space technology organisation is looking for an experienced Spacecraft Systems Engineer to join its growing engineering team.

This is an excellent opportunity to play a central role in the design and development of complex spacecraft missions, working across multiple engineering disciplines to develop robust, achievable technical solutions.

The Role

As a Spacecraft Systems Engineer, you will act as a technical architect across the mission lifecycle, supporting system design, requirements, trade-offs, integration, verification and ultimately spacecraft operations.

Key responsibilities include:

- Develop spacecraft mission and system-level designs.
- Derive, allocate, verify and maintain system requirements and traceability.
- Perform system-level trade studies and technical assessments.
- Manage spacecraft budgets including mass, power, data and propellant.
- Produce and maintain CONOPS, V&V plans, ICDs and other systems engineering documentation.
- Own and manage system-level interfaces, including space-to-ground and TM/TC.
- Support spacecraft testbeds, validation and system-level testing.
- Contribute to FDIR, FMECA and fault-tree activities.
- Coordinate engineering activities across multiple subsystem teams.
- Support spacecraft integration, verification and environmental test campaigns.
- Present technical analyses and recommendations to internal and external stakeholders.
- Contribute to bids, proposals and early-stage mission studies.
- Support key programme reviews including SRR, PDR, CDR and TRR.
- Provide technical support during commissioning and critical in-orbit operations.

About You

We're looking for a systems engineer with experience working on satellite or similarly complex aerospace systems.

Essential experience:

- 2+ years' experience in satellite systems engineering.
- Good understanding of the key subsystems that make up a spacecraft.
- Experience with requirements derivation, verification and traceability.
- Strong analytical skills and the ability to perform complex technical trade-offs.
- Excellent communication and stakeholder management skills.
- Comfortable using Microsoft Office, particularly Word, Excel and PowerPoint.

Desirable Experience

- Understanding of attitude and orbit control systems (AOCS).
- Satellite-level AIT experience.
- Exposure to FFT, STB, TM/TC and MIB activities.
- Mission operations experience.
- Experience with GMAT or Orekit.
- Python, MATLAB or other engineering analysis tools.
- FMECA, FDIR, fault-tree analysis or reliability engineering.
- Experience working on institutional or ESA missions.

What’s on Offer

- Hybrid working with flexible core hours.
- Optional compressed working pattern.
- 25 days' holiday, increasing to 28 with service, plus Bank Holidays.
- Private healthcare, life insurance and long-term sick pay.
- Relocation support may be available.
- Modern engineering and cleanroom facilities.
- Regular social and team events.
- The opportunity to work on technically challenging spacecraft and space missions.
