About the Company
Infinite Orbits Luxembourg is the Luxembourg subsidiary of Infinite Orbits SAS (Toulouse, France), a NewSpace company founded in 2017 that now counts more than 200 colleagues across locations including Spain, Germany and the UK.
We develop in-orbit servicing solutions - from awareness, inspection, and protection of space assets to life extension and satellite servicing - built on our own Autonomous Vision-Based 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.
Specifically, IO Luxembourg is focusing on the design, development, integration and testing of cutting-edge software playing a critical role in the missions as well as being responsible for Spacecraft Operations.
About the Role
The Flight Operations Engineer is to define and develop the operations concept and procedures for a Geo-orbit satellites providing space-based services such as Space Situational Awareness (SSA).
Initially, the role will focus on transforming high-level Concepts of Operations (ConOps), subsystem specifications, and software/equipment documentation into a cohesive Flight Operations architecture. Over time, this position will evolve to include hands-on execution of flight operations once the satellite becomes operational.
Job Description
Phase 1 – Design & Definition:
Analyze mission-level Concepts of Operations (ConOps) and derive detailed Flight Operations concepts and requirements.
Define operational modes, sequences, and decision trees for nominal and off-nominal scenarios.
Interface with spacecraft subsystem teams (ADCS, thermal, propulsion, communications, etc.) to understand equipment capabilities, constraints, and telemetry/command interfaces.
Collaborate with ground segment, mission planning, and software teams to define required tools and interfaces.
Develop and document:
Operations Concepts (ConOps)
Flight Operations Manual (FOM)
Flight Operating Procedures (FOPs)
Contingency and anomaly response plans
Participate in system integration and test campaigns to validate operational concepts and procedures in simulated environments.
Phase 2 – Operations Execution:
Support or lead day-to-day mission operations post-launch, including planning, commanding, and monitoring of spacecraft activities.
Participate in shift rotations for LEOP (Launch and Early Orbit Phase) and commissioning, as needed.
Monitor spacecraft health and safety, investigate anomalies, and execute recovery actions.
Interface with external customers or users services to ensure mission responsiveness and data continuity.
Continuously refine operational procedures based on in-flight data and lessons learned.
Requirements
Bachelor’s degree in Aerospace Engineering, Systems Engineering, Physics, or related field.
3+ years of experience in satellite mission operations or flight systems engineering (preferably LEO or GEO missions).
Strong understanding of spacecraft subsystems and ground segment interactions.
Experience writing technical documentation and procedures.
Familiarity with operational software tools (e.g., SCOS-2000).
Comfortable working across multiple teams and managing ambiguity in early mission phases.
Preferred:
Experience with GEO satellite operations.
Experience with test campaigns and spacecraft simulators.
Python experience for tools automation or telemetry analysis.
Ability to work shifts during critical mission phases (LEOP, anomaly resolution).
What we offer
The opportunity to be part of an international team transforming the space industry.
A creative and innovative work environment where ideas turn into reality.
Competitive salary and benefits.
