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…
We have a need for a number of Optical Systems Engineers to join us and lead the development of optical payloads for Earth observation missions, owning the journey from concept through to launch and in-orbit operations.
This is a role for individuals who like combine deep optical engineering expertise with systems thinking and programme ownership, and who enjoy turning complex ideas into flight-ready space systems.
What You'll Be Doing
You will take technical ownership of optical payload developments, working across engineering teams, partners, and suppliers to deliver high-performance missions at speed.
Your responsibilities will include:
- Owning the end-to-end development of optical payloads, from requirements and concept definition through design, testing, launch and in-orbit commissioning.




- Acting as the technical authority for optical payload work packages, ensuring mission performance and delivery.
- Performing mission analysis and system design for optical Earth observation systems, defining requirements, CONOPS and system budgets.
- Driving optical payload performance, managing image quality metrics such as MTF, SNR, resolution and detector behaviour.
- Leading design trade-offs to optimise performance, cost, risk and schedule across the payload and spacecraft system.
- Planning and supporting AIT/AIV activities, including optical alignment, calibration, characterisation and testing.
- Coordinating engineering across satellite subsystems and external suppliers to deliver integrated mission solutions.
- Supporting technical proposals, customer discussions and new mission concepts that push the boundaries of Earth observation from space.

What You’ll Bring
You should have:
- Strong capability in optical space systems
