Working for Open Cosmos

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 the Satcoms Software Team

Our team designs, builds, and operates the software infrastructure behind Open Cosmos’ satellite communications services. From network planning and mission simulation to real-time telemetry processing and digital twin modelling, we provide the foundation for scalable, intelligent, and secure connectivity from space to ground. We use modern technologies, agile methods, and collaborate closely with hardware, mission, and commercial teams to deliver value quickly.

What will you be doing?

We are looking for a Test Automation Engineer to help build the tools, infrastructure, and processes that support integration, verification, and validation (IV&V) across our Satcom product lines. Your work will enable us to scale manufacturing, integration, and service readiness as Open Cosmos expands its global connectivity services.

In this role, you’ll develop and maintain automated test frameworks for system integration, functional validation, and performance testing. You’ll implement workflows for HIL, SIL, and NIL environments, and collaborate with cross-functional teams to convert system requirements into automated, traceable test cases. Your testing solutions will be integrated into CI / CD pipelines for early fault detection and rapid iteration.

You’ll also support test campaigns, lab automation, and in-orbit validation, while helping to build scalable test environments that grow with our mission demands.

What you need to be successful

We value your skills and mindset. If this role excites you, we want to hear from you, even if you are not sure you meet every qualification.

Different seniority levels will be considered for this role.

To succeed, you will need :

• A strong background in test engineering, automation, or system integration (space or telecom sector preferred).
• Proficiency in developing test automation tools and frameworks using Python, C++, or other scripting languages.
• Familiarity with communication systems, RF testing, digital interfaces, or network validation.
• Understanding of satellite systems, payload behaviour, and performance metrics is a plus.
• Hands-on experience with lab instrumentation (spectrum analysers, signal generators, VNAs) and automated control via software.
• Knowledge of CI / CD environments and test integration tools (e.g., Jenkins, GitLab, Robot Framework).
• Excellent problem-solving skills, attention to detail, and a collaborative approach.
