Optical AIV Engineer

SatVu is a rapidly expanding space technology company, backed by leading investors like Adara Ventures and Lockheed Martin. As the 'World’s Thermometer,' we deliver high-accuracy thermal datasets from space, providing invaluable insights across sectors. Our cutting-edge technology fuels significant growth in climate, sustainability, and defence & intelligence/national security markets, with HotSat-1 launched in 2023 and HotSat-2 and HotSat-3 planned for 2026.

This is an exciting opportunity to join a dynamic, high-growth organisation at a pivotal moment in its development.

The Role

SatVu is seeking an Optical AIV Engineer to support on-site assembly, integration and verification of the HotSat-4 optical instrument at Surrey Satellite Technology Ltd (SSTL) in Guildford. This is an on-site role requiring presence five days per week for the payload build phase.

You will be embedded within SSTL’s Optical AIV and Optical Imaging teams to perform precision optical/mechanical assembly, instrument AIV, operation of interferometers/CMMs/MTF rigs/TV chambers and bespoke test equipment, and to deliver verified flight hardware. Following the active build, you will contribute to SatVu’s technical team to capture lessons learned and support future payload AIV planning as we grow the constellation. Day‑to‑day technical direction will come from SSTL’s Optical AIV leads on-site; overall line management will report to SatVu’s Head of Programmes.

This position offers an opportunity for professional growth and the chance to make a meaningful impact within a dynamic and rapidly growing company.

Key Responsibilities:

• Carry out optical and mechanical alignment of instruments; perform AIV activities in cleanroom and lab environments.
• Operate and maintain test equipment (interferometers, CMM, thermal vacuum, MTF rigs, integrating spheres).
• Build and verify optical, mechanical and electrical ground support equipment.
• Troubleshoot, report and resolve hardware issues; author and maintain build/test procedures, reports and cleanroom records.
• Prepare and manage build materials and cleanliness protocols.
• Capture detailed AIV documentation and lessons learned to support IP transfer and SatVu lab setup.
• Liaise with design teams to feedback producibility and testability observations
• Work closely within a core project team

Essential Qualifications and Experience:

• Degree in engineering, optics or equivalent.
• Practical AIV experience in low-volume, high-technology manufacturing; cleanroom experience essential.
• Experience handling optics and optical test hardware; operation of interferometers, CMMs, or thermal-vacuum chambers is desirable.

Desirable Skills and Experience:

You don’t need to tick every box to apply—we value curiosity, learning, and the ability to add impact. These are some of the ways you may bring value:

• Detail-oriented, methodical, good with hands‑on instrumentation and procedures.
