AIT Engineer

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 Operating Office (COO)

Our COO Teams are the engine that powers Open Cosmos’ operations. This division brings together mission management, supply chain, and quality & product assurance to make sure every mission is delivered smoothly, reliably, and to the highest standards. They turn plans into action, keeping us efficient and mission-ready at all times.

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 You'll Be Doing

You will be:

• Developing and executing spacecraft Assembly, Integration, and Test (AIT) plans and procedures

• Leading satellite integration activities including mechanical assembly, electrical integration, and subsystem validation

• Defining test campaigns for spacecraft and subsystems including functional, environmental, and performance testing

• Supporting the development and verification of electrical harnesses, payload integration, and subsystem interfaces

• Analyzing test results and troubleshoot anomalies, working closely with subsystem engineers to identify root causes and implement corrective actions

• Preparing and maintaining AIT documentation including procedures, test reports, and configuration records

• Ensuring compliance with cleanroom, ESD, and quality assurance processes during all integration activities

• Supporting environmental testing campaigns such as vibration, thermal vacuum, and functional validation

• Contributing to satellite launch campaign preparation, including final functional verification and integration into deployers or launch adapters

• Supporting continuous improvement of AIT processes, tooling, and documentation to improve efficiency and quality

What You’ll Bring

• Strong understanding of spacecraft systems and subsystem integration

• Ability to develop and execute integration and test procedures

• Knowledge of electrical and mechanical spacecraft interfaces including harnessing and subsystem integration

• Familiarity with laboratory test equipment such as oscilloscopes, power supplies, multimeters, and data acquisition systems

• Ability to interpret system schematics, interface control documents (ICDs), and engineering drawings

• Ability to analyse test results and resolve integration or system anomalies

• Strong documentation and configuration management practices

• Understanding of environmental testing processes including vibration and thermal vacuum testing

This role will be based onsite in Athens, Greece.
