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 or Hybrid - Germany
Team & Reporting Line: Program Management Team | Reports to Lead Project & Procurement Manager
Your Role
We are looking for a proactive and detail-driven team player to join our Product and Quality Assurance (PQA) team, with a strong focus on Flight Software Product Assurance.
In this role, you will play a critical part in ensuring the quality, safety, and reliability of both flight and ground software across our growing satellite constellation. You will work at the intersection of engineering, quality, and operations, helping to shape how we build and deliver software in a fast-moving, mission-critical space environment.
The PQA team defines and maintains the company’s quality and Product Assurance standards. Your work will directly contribute to ensuring our software meets the highest levels of robustness, compliance, and reliability, supporting mission success in both orbit and ground operations.
This is a role for someone who thrives in complex, technical environments, enjoys working across disciplines, and is comfortable balancing structured quality processes with the pace of a rapidly scaling space organisation. You will be trusted to take end-to-end ownership, bring clarity to ambiguity, and help embed strong engineering discipline across the software lifecycle.
Key responsibilities
Develop, implement, and continuously improve a robust Software Product Assurance (PA) programme, reporting directly to the Product Assurance Manager.
Take end-to-end ownership of Software Product Assurance across both flight and ground software for our satellite constellation.
Ensure rigorous application of software configuration management and release processes, maintaining strong version control, traceability, and engineering discipline.
Enforce compliance with safety-critical and mission-critical software standards, with a strong focus on risk reduction and failure prevention.
Define and oversee software testing, verification, and validation strategies across all development and delivery phases.
Investigate, manage, and resolve software anomalies throughout development, testing, integration, and operational phases.
Support Spacecraft Assembly, Integration and Testing (AIT) activities, ensuring software readiness and compliance at every stage.
Coordinate and lead software deliveries from suppliers, ensuring alignment with internal standards, schedules, and quality expectations.
Participate in subcontractor reviews and key technical meetings, working closely with procurement engineers and Product Assurance stakeholders.
Balance the demands of rapid development cycles with the need to maintain strong Product Assurance and software quality standards in a fast-paced space environment.
About You
