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 Core Role 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 Optional (If you have this experience) - Involvement in satellite operations, your role will also include: Monitor and control spacecraft operations, ensuring the nominal health, safety, and performance of the satellite constellation Execute real-time spacecraft commanding, telemetry monitoring, and analysis, responding promptly to off-nominal conditions. Develop, validate, and maintain operational procedures for both routine activities and contingency scenarios. Collaborate closely with Flight Dynamics and Mission Planning teams to execute mission timelines and scheduling activities. Support the commissioning and early operations phases of newly launched satellites. Investigate anomalies, perform root cause analysis, and implement corrective and preventive actions. Ensure high availability and smooth operation of the ground segment, participating in on-call rotations as required.
