Senior Infrastructure Operations Engineer

Team & Reporting Line: IT Team, reporting to the IT Director

Our Mission At constellr, we use thermal intelligence from space to understand what is happening on Earth - where, when and at scale. Our satellite constellation delivers high-resolution land surface temperature data, giving governments, defence organisations, commercial operators and global institutions the intelligence they need to monitor change, assess risk and make better-informed decisions.

From national security and critical infrastructure to agriculture and climate resilience, constellr turns temperature into actionable intelligence for a changing world.

Your Role You'll design and maintain the infrastructure backbone that keeps constellr's operations reliable and scalable, from our office networks to the server room that supports our satellite data.
