- 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.

You should have:

- Strong capability in optical space systems, Earth observation and remote sensing
- Ability to develop optical payloads from concept through to commissioning
- Deep understanding of image quality metrics and budgets (MTF, SNR, resolution, detectors)
- Knowledge of optical system manufacturing, alignment, calibration and testing
- Strong systems engineering capability (requirements, CONOPS, system budgets, FMECA/FDIR)
- Understanding of satellite subsystems and multidisciplinary engineering environments

For this role you can be based in any of our locations.
