Aim high, go beyond!

At Open Cosmos we are solving the world’s biggest challenges from space, providing businesses, governments and researchers access to more readily available information than ever before - ready for the challenge? Then read on…

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.

Working in the AIT Team

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.

From assembling delicate electronic boards to fitting structural panels, wiring harnesses, and payloads, AIT ensures everything fits and functions flawlessly. They run rigorous testing — vibration, thermal vacuum, functional, and performance checks — to make sure each satellite can survive the extreme conditions of launch and space.

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

What will you be doing?

You will be:

• Supporting the assembly and integration of satellite structures, subsystems, and components

• Assisting with mechanical and electrical integration activities including harness routing, connector mating, crimping, and soldering under supervision

• Supporting spacecraft functional testing and verification activities

• Assisting in preparing cleanroom environments, tooling, and equipment for integration campaigns

• Maintaining high standards of workmanship, cleanliness, ESD compliance, and configuration control

• Supporting the completion of build records, test documentation, and traceability logs

• Assisting with hardware handling, stock management, and inventory activities

• Working closely with engineers and technicians to identify and resolve integration or test issues

• Supporting environmental test campaign preparation activities where required

What You’ll Bring

• A strong interest in spacecraft, satellite systems, or aerospace engineering, most likely gained from a recent relevant apprenticeship or degree in Aerospace Engineering, Mechanical Engineering, Electrical/Electronic Engineering, Physics, or a related discipline

• A practical, hands-on mindset with an interest in hardware assembly and testing

• Basic understanding of mechanical and electrical systems

• Familiarity with laboratory, workshop, or electronics equipment is advantageous

• Ability to interpret technical drawings or engineering documentation is desirable

• Good attention to detail and organisational skills

• Strong communication and teamwork skills

• Willingness to learn and develop in a fast-paced engineering environment

This role will be based onsite in Athens, Greece.
