About the Company
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.
"Endurance" is a docking service capable of extending the life of GEO telecom satellites, by taking over AOCS takeover for 5 years.
About the Role
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.
Job Description
Key Responsibilities
1. Optical Integration & Alignment
Perform precision alignment of optical assemblies, including lens-to-detector alignment.
Define and execute alignment procedures (focus, tilt, centering, boresight).
Useoptical metrology tools (collimators, interferometers, autocollimators, MTF benches).
Analyze optical defects (defocus, aberrations, misalignment).
2. 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.
3. Verification & Testing
Define and implement optical acceptance test procedures at:
Unit level (sensor, lens, camera).
Subsystem level.
Satellite level.
Perform optical performance characterization:
Imagequality (MTF, encircled energy, PSF).
Radiometric checks (relative calibration).
Straylight / ghost analysis.
Support environmental test campaigns (TVAC, vibration) and assess impact on optical performance.
4. 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.
