Satellite Operator

Team & Reporting Line: Flight Operations /Satellite Operations

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

Your Role

As a Satellite Operator, you sit at the console where our constellation meets the ground. You will be part of the Satellite Operations team, working a shift rotation alongside a small, senior group of operators and reporting to the Flight Operations Team Lead, with a Flight Director on call for every critical decision. Day to day you will fly the spacecraft: monitoring routine passes, executing special requests from internal stakeholders, reacting to off-nominal behaviour with disciplined procedure execution, and driving anomalies through to closure.

You will work shoulder to shoulder with Mission Control, Mission Planning, Flight Dynamics, Ground Segment and the platform and payload engineering teams, which makes this one of the best seats in the company for understanding how the whole mission fits together. Every procedure you author, every automation script you contribute and every anomaly you close makes the fleet safer and increases the volume and quality of thermal data we deliver to customers who depend on it for climate resilience, food security and national security decisions.

Key responsibilities

• Fly the constellation on a shift rota: pass preparation, telemetry monitoring, commanding, command schedule uplink, payload downlink verification and end-of-shift handover reports.
• Execute non-routine and special tasking per applicable flight procedures: priority tasking, calibration and characterization campaigns, payload reconfiguration, onboard software and table uploads, collision avoidance and orbit maintenance.
• Act as first responder to off-nominal events and alarms: diagnose using contingency procedures, place the spacecraft in a safe configuration, and log the event with supporting evidence in the anomaly management system.
• Drive anomalies to closure with platform, payload and ground segment engineering: track corrective actions, prepare and validate recovery activities, and verify the fix on orbit.
• Escalate to the Flight Director, with a clear situation assessment, whenever an event falls outside existing procedures, exceeds operator authority or threatens mission availability.
• Interface with Mission Control, Mission Planning, Flight Dynamics and Ground Segment: validate planning products and pass schedules, coordinate manoeuvres and collision-avoidance actions, and report station or link degradations.
• Write and improve flight procedures, checklists and operational documentation, capturing lessons learned from each anomaly and shift so problems are not solved twice.
• Automate operations with developers: scripting of repetitive tasks, telemetry trending and analysis tools, monitoring dashboards and alerting rules.
• Monitor fleet health and performance trends, raise early warnings on degrading subsystems, and report KPIs such as pass success rate, data volume delivered and anomaly turnaround time.
• Support LEOP and commissioning for new satellites: simulations, operational readiness tests and shift staffing for…
