We are seeking an experienced Optical Systems Engineer with deep expertise in Earth Observation (EO) satellite optics to lead the technical development of a spaceborne optical payload for our New Space client - a rapidly expanding space technology company based in the UK.

This role is based full-time onsite (5 days per week) in Guildford for the duration of the payload build phase.

You will be embedded within the satellite manufacturer’s Optical Imaging team, driving optical system architecture, performance, integration and verification during an intensive hands‑on build programme. Following completion of the build phase, you will transition into a broader technical role supporting future payload development and long‑term optical strategy.

You will receive day‑to‑day technical direction from the onsite Optical Lead, with overall line management provided by your employing organisation.

This is a senior, hands‑on opportunity to shape and deliver high‑performance optical systems for Earth Observation satellites.

• Lead development of optical system architecture, requirements and trade studies for an EO payload
• Perform optical design, modelling and performance analysis (image quality, MTF, stray light, tolerancing)
• Define subsystem and component specifications; oversee manufacturing and supplier activities
• Participate hands‑on in optical integration, alignment and verification activities
• Support environmental testing and performance validation
• Maintain risk registers, mitigation plans, development schedules and technical inputs
