Mission Control Engineer

Our Mission

At constellr, we're harnessing the power of space to solve one of Earth’s greatest challenges: climate resilience & security in a changing world. Our thermal satellite constellation delivers the most accurate land surface temperature data on the market, equipping commercial players, governments, defence agencies, and global institutions with the thermal intelligence they need to make strategic decisions– from national security and infrastructure to agriculture and climate resilience. As a fast-scaling company with offices in Brussels, Freiburg, Munich, Washington and Toulouse, our multidisciplinary team of engineers, scientists, and strategists is building the future of space-based Earth observation Location: Remote - Germany Team & Reporting Line: Flight Operations - Reporting to Lead Satellite Systems Your Role As a Mission Control Engineer, you will be central to operating and scaling our Earth Observation satellite constellation. You will monitor, control, and optimise spacecraft performance while working closely with the Flight Operations team and collaborating with Flight Dynamics, Payload, Software, Data, and Product teams across the company. This role offers the opportunity to build and operate mission control systems from the ground up in a fast-paced startup environment, with direct impact on the reliability, availability, and quality of the data we deliver to customers. At constellr, you will help shape how our constellation and operations scale, owning critical operational capabilities, influencing system design, and seeing the immediate real-world impact of your work. The role also provides a clear growth path into hands-on satellite operations, with opportunities to take on real-time spacecraft commanding and monitoring responsibilities and contribute directly to mission success in orbit. Key responsibilities Build core mission planning services and algorithms that power mission planning applications for a growing satellite constellation Shape the architecture and design of mission planning systems to ensure scalability, reliability, and long-term operability Run, monitor, and maintain mission planning systems in live production environments Define engineering standards for reliability, CI/CD, infrastructure-as-code, observability, safety, and operational compliance Collaborate across Flight Operations, Flight Dynamics, Payload, Satellite Operations, and Product leadership to turn mission needs into technical direction and system design Drive adoption of CI/CD pipelines, infrastructure-as-code, and robust deployment practices across mission-critical systems Translate mission requests into executable satellite telecommands, including interaction with the telecommand database Align mission plans with onboard scheduling and execution constraints to ensure feasible satellite operations About You Essential Experience: Bachelor’s or Master’s degree in Aerospace Engineering, Computer Science, or a related technical field. 2–3+ years of experience in satellite/spacecraft operations or in ground segment / Mission Control System development, either on the operations or software side. Solid understanding of spacecraft subsystems (e.g., AOCS, power, thermal, communications). Experience with telemetry analysis, command systems, and operational procedures. Proven ability to troubleshoot anomalies under time pressure using structured and methodical problem-solving approaches. Strong software engineering background, with experience in a systems programming language (ideally Rust, but C, C++, or similar are acceptable; support will be provided to develop Rust expertise). Experience developing reliable software for operational environments, with a strong focus on correctness, robustness, and safety. Familiarity with Linux systems and server administration. Knowledge of space industry standards such as CCSDS, ECSS, or PUS (deep expertise not required; familiarity with the ecosystem is sufficient). Strong communication skills and a collaborative mindset; ability to work closely with operations teams and the broader Mission Control organisation. Willingness to work in an operational environment, including shifts or on-call duties when required. Experience with monitoring and data infrastructure tools such as Grafana (including IRM), InfluxDB, and PostgreSQL. Genuine interest in working at the intersection of spacecraft operations and modern systems software, with a willingness to deepen expertise in either domain. Ability to develop reliable, production-grade software for 24/7 operational environments, with a strong focus on correctness, robustness, and safety. Nice to have: Experience with LEO Earth Observation missions. Knowledge of mission planning systems and ground station networks. Experience with SCOS-2000 and Mission Information Base (MIB) configuration. Background in Launch and Early Orbit Phase (LEOP) or in-orbit commissioning. Experience working in a startup or fast-scaling environment. Familiarity with cloud-based infrastructure, distributed systems, or data pipelines. Understanding of satellite systems engineering principles. Exposure to or experience with AI-assisted development tools or workflows. Why Join constellr?
