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
As a Full-Stack Engineer on the Ground Segment Software team, you'll help design and build the software tools that the mission team uses to calculate, monitor, perform and plan operations. Among others, these tools are essential to realise flight dynamics operations from ground, and to command, control, and safely conduct rendezvous and docking operations with client spacecraft. This is a hands-on engineering role at the core of our ground infrastructure.
Job Description
Build and maintain backend services (Python, Go and Typescript) for telemetry processing and telecommanding, enabling operators to monitor and control the satellite's trajectory and state, both absolute and relative to the client spacecraft, during rendezvous and docking
Develop operator-facing web interfaces (React, Next.js) for controlling and operating the rendezvous and docking equipment, and for verifying and validating operations before execution, including by interfacing with mission simulators
Implement responsive, low-latency UIs backed by live data streams (e.g. WebSockets / server-sent events), keeping the operator view in sync with the spacecraft
Design and optimize data models and queries against SQL databases (PostgreSQL / time-series stores) for mission data handling
Design and consume service APIs over gRPC and REST to integrate the MCS components and operational tooling
Work with object/file storage services (e.g. MinIO, S3-compatible stores) to handle mission data, downlinked imagery, and archives, including the telemetry and images that drive relative-trajectory monitoring
Deploy, run, and troubleshoot services on Kubernetes across cloud environments (AWS, OVH)
Build and maintain CI/CD pipelines to ship reliably and repeatably
Write unit, integration, and system-level tests to keep the codebase robust and mission-ready
Requirements
2–3 years of professional software engineering experience
Solid proficiency in Python, Go and Typescript
Frontend experience with React and Next.js
Strong grasp of SQL databases and data modeling
Experience designing and building APIs with gRPC and REST
Hands-on experience with Kubernetes and container-based deployment
Experience with cloud platforms (AWS, OVH, or equivalent)
Experience with object/file storage services (MinIO, S3, or similar)
Experience building CI/CD pipelines
A solid testing discipline, comfortable writing unit, integration, and system tests
Strong communication skills and ability to work in a cross-disciplinary team
Nice to have
Experience with space, aerospace, or other mission-critical / real-time systems
Familiarity with messaging systems (e.g. NATS, Kafka, RabbitMQ) and event-driven architecture
Exposure to ground segment standards (CCSDS, ECSS/PUS, XTCE) or mission control software (YAMCS, SCOS-2000)
Rust exposure
