Working in our Chief Technology Office (CTO)

The CTO division is where Open Cosmos technology comes to life. Covering engineering, product development, and technical innovation, the team designs, builds, and operates the satellites, systems, and platforms that make our missions possible. It’s a highly collaborative environment where ideas become real hardware, software, and data solutions that deliver impact from space.

The AIT team is at the heart of turning ideas into real, orbit-ready satellites. They’re the workshop where Open Cosmos missions come to life — taking designs from paper to physical hardware.

It’s hands-on, fast-paced, and mission-critical - it doesn’t get much cooler than this!

What You'll Be Doing

As an AIT Technician, you’ll be part of the team that physically builds our satellites. From assembly to launch integration, you’ll bring spacecraft to life and ensure they’re ready to perform in orbit.

You’ll work hands-on in cleanroom environments, and collaborate with engineers across disciplines. If you’re meticulous, curious, and motivated by seeing your work literally leave the planet, this is your opportunity to make an impact.

• Confident soldering, crimping, and building harnesses to high standards
• Familiar with cleanroom practices and ESD safety
• A proactive and organised approach to work
• A team-oriented mindset and eagerness to learn

This role will be based onsite in Athens, Greece.
