Senior Opto-Mechanical Engineer

About the role

AMOS (Advanced Mechanical & Optical Systems), based in Liège and part of the Belgian satellite manufacturer Aerospacelab, develops ultra-high opto-mechanical systems for space and professional astronomy, including the Very High Resolution (VHR) optical payloads of Earth observation satellites. It is looking for a Senior Opto-Mechanical Engineer (M/F) within its Mechanical Design division, assigned to the VHR payload team. The engineer is responsible for the design, manufacturing follow-up and acceptance inspection of the opto-mechanical part of the payload and acts as the opto-mechanical reference of the team.

Key responsibilities

• Analyse opto-mechanical requirements and ensure they are met during design
• Design assemblies such as mirror mounts and flexures, metering structures, focal plane interfaces, baffles and mechanisms
• Select materials and components (mirror substrates SiC, Zerodur, ULE, CFRP and Invar structures, bearings, bonded joints, fasteners)
• Justify the design against launch loads, thermal gradients and gravity release, support STOP analyses, define alignment and adjustment concepts, and specify integration tooling and metrology means
• Draft specifications, follow up subcontractors and the manufacturing of critical parts (lightweighting, bonding, coating)
• Take charge of integration, alignment and validation, and support vibration and thermal-vacuum test campaigns
• Contribute to the modular VHR product line, review junior engineers' designs and share design rules
• Produce the required technical documentation

Required profile

• Master's degree in Electromechanical, Mechanical or Aerospace Engineering or equivalent, with at least 8 years of experience in opto-mechanical or precision mechanical design
• Space field experience required; experience on optical instruments or VHR payloads is a strong asset
• Understanding of how mounts, materials and thermal gradients affect wavefront error and line-of-sight drift
• Minimum English level B1

Required skills

• CAD software, ideally CATIA V5 or NX
• FEM analysis (Nastran or SAMCEF solvers in the SIMCENTER environment)
• Precision metrology (interferometry, CMM, laser tracker) and clean room practice
• Familiarity with ECSS standards

What we offer

• A permanent position
• A flat hierarchy and a fast-paced environment
• Flexible ways of working
• A salary package consistent with experience
