Optical AIT Engineer

About Infinite Orbits

Established in 2017, Infinite Orbits is a NewSpace company, based in Toulouse, pushing the boundaries of in-orbit services with cutting-edge spacecraft driven by its own Rendez-Vous solution, an advanced Autonomous Vision-Based Navigation Solution. IO has two generations of missions

"Orbit Guard" provides Inspection and Space Situational Awareness services in GEO. Our first, OG-1 was launched on 1 May 2023, the second is launching in 2025 and the third third launching in 2026.

"Endurance" is a docking service capable of extending the life of GEO telecom satellites, by taking over AOCS takeover for 5 years.

Infinite Orbits is looking for an experienced Optical AIT Engineer to support the integration and validation of an optical payload. The role focuses on optical alignment, camera-level integration, and end-to-end optical performance verification at subsystem and satellite level.

This position requires a strong combination of optical engineering expertise, hands-on integration experience, and strict adherence to cleanroom best practices.

Key Responsibilities

Optical Integration & Alignment

• Perform precision alignment of optical assemblies, including lens-to-detector alignment.
• Define and execute alignment procedures (focus, tilt, centering, boresight).
• Use optical metrology tools (collimators, interferometers, autocollimators, MTF benches).
• Analyze optical defects (defocus, aberrations, misalignment).

Camera & Payload Integration

• Supervise and support camera integration activities from an optical standpoint.
• Interface with mechanical, thermal, and electronics teams to ensure system-level consistency.
• Validate optical performance after integration (PSF, MTF, focus stability).
• Contribute to integration flow definition and optimization.

Verification & Testing

• Define and implement optical acceptance test procedures at:
  • Unit level (sensor, lens, camera).
  • Subsystem level.
  • Satellite level.
• Perform optical performance characterization:
  • Image quality (MTF, encircled energy, PSF).
  • Radiometric checks (relative calibration).
  • Straylight / ghost analysis.
• Support environmental test campaigns (TVAC, vibration) and assess impact on optical performance.

Cleanroom Operations

• Conduct all activities in controlled cleanroom environments (ISO 5-8).
• Apply strict contamination control procedures.
• Handle sensitive optical components following space-grade cleanliness standards.
• Define and enforce cleanroom best practices.

Le profil recherché

• Master's degree or PhD in: Optical Engineering, Physics (Optics specialization), Aerospace Engineering.
• 5+ years experience in optical AIT, preferably in space or high-performance imaging systems.
• Technical skills:
  • Optical Expertise
    • Strong understanding of: Imaging systems and PSF/MTF concepts. Optical alignment techniques. Radiometry fundamentals.
    • Experience with: Optical test equipment (collimators, interferometers, MTF benches). Image quality analysis tools.
  • AIT & Cleanroom Experience
    • Proven experience in: Cleanroom operations (ISO 5-8). Handling flight hardware. Contamination control.
    • Familiarity with: Space qualification standards (ECSS, NASA, or equivalent).
