Front-End IT Specialist

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

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 build and maintain the internal tools and interfaces that constellr's teams rely on every day. Your goal is to make our internal systems as usable and well designed as the technology we send into orbit, so our people can focus on their work rather than their tools.

Key responsibilities

• Build and maintain the web tools and applications our internal teams use
• Support our users on the front end by providing training, answering questions and troubleshooting issues
• Make sure our apps integrate seamlessly with one another, giving users a smooth and connected experience
• Work closely with back-end IT and business stakeholders to understand and shape the requirements for each tool
• Keep clear, up-to-date documentation for all our internal tools
