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 our Chief Technology Office

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.

Our Systems Team brings together brilliant Systems, AOCS and Thermal Engineers who turn ambitious mission concepts into reality. They design, integrate, and optimise every detail – from spacecraft architecture to next-generation optical payloads – making sure every system fits, works, and thrives in orbit. From first sketch to launch day, they own the journey, ensuring our satellites deliver maximum impact back on Earth

What will you be doing?

As a Senior Systems Engineer at Open Cosmos, you'll play a key role in delivering fully integrated space missions from concept to orbit. You’ll be the technical driving force, bringing together multidisciplinary teams to turn ambitious ideas into real-world impact.

• Own the technical delivery of space missions — you're the go-to person for mission architecture and execution

• Lead cross-functional teams to develop consistent, reliable system-level solutions

• Define and manage mission requirements and drive verification across the lifecycle

• Run system-level analysis, perform trade-offs, and ensure optimal design decisions

• Develop and implement MBSE (Model-Based Systems Engineering) tools, processes, and methodologies

• Conduct FMECA and design FDIR strategies to enhance mission resilience

• Create and maintain systems-level documentation to ensure traceability and technical excellence

• Support pre-sales, bids, operations, and customer teams with expert technical insight

• Thrive under pressure, take initiative, and drive progress without waiting for instructions

• Embrace complexity, push boundaries, and always look for better ways to deliver

What you will need to succeed

We’re looking for a bold, hands-on systems thinker with the technical depth and leadership to deliver space missions from the ground up.

• End-to-end experience in satellite systems engineering — from concept to deorbit

• Proficient in MBSE tools and methodologies

• Skilled in FMECA, FDIR, and CONOPS development

• Strong knowledge of core satellite subsystems:
  • Power systems
  • On-board computers
  • AOCS
  • Communications
  • Propulsion
  • Mechanical/thermal systems

• Hands-on AIT experience (Assembly, Integration, Testing)

• Familiar with the regulatory landscape: frequency allocation, export control, insurance, and debris mitigation

• Proven track record managing supplier relationships and cross-team communication
  
  

To apply, you must have the legal right to work in your chosen location.

Why Open Cosmos?

• Work at the cutting edge of space technology with customers around the globe.

• A mission-driven company making space accessible to help solve real-world challenges.

• A diverse, ambitious, and supportive team.
