Full-Stack Engineer

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

• 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.
• 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

• 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
