Optical Systems Engineer

Salary: £33,000 - 69,000 per year

• We are looking for an Optical Engineer with experience in both optical design and assembly, integration, and test.
• We require experience defining requirements for optical systems and performing modelling and trade studies to inform design selection.
• We require optical design and analysis experience using Zemax or similar software for design, optimisation, and tolerancing, with sequential and non‑sequential experience desirable.
• We require hands‑on experience with photonic components and systems, including lasers, optical detectors and receivers, modulators, and fibre and free‑space optics.
• We require a strong understanding of the physical principles and performance trade-offs of optical and photonic systems.
• We require hands‑on laboratory experience designing and carrying out tests for relevant optical systems.
• Desirable experience includes electronics for optoelectronic systems, such as analogue front‑ends, high‑speed data converters, embedded FPGAs, and power, EMI, and thermal considerations.
• Desirable experience includes optical or RF communication systems, including modulation schemes, error correction, FPGA or SDR modem implementation, and relevant protocols such as CCSDS, Space Wire, and Ethernet.
• Desirable experience includes high‑power lasers, optical amplifiers, and relevant safety requirements.
• Desirable experience includes optical instrument calibration, alignment, and procedure definition.

• We will have you design laser communication terminal optical and photonic subsystems for extreme environments.
• We will have you define requirements and perform trade‑off analysis for complex optical and photonics systems, balancing performance against cost.
• We will have you model optical system performance, optimisation, and tolerancing.
• We will have you conduct practical breadboard testing to validate modelled data.
• We will have you assemble, integrate, and test subsystems.
• We will have you support system‑level testing and trials.
• We will have you act as a subject matter expert for optical and photonic systems.
• We will have you manage suppliers of optical and photonic components.
• We will have you provide technical leadership for subsystem development projects.
• We will have you work closely with our Product Technical Lead and optical engineering team.
