Optical Systems Engineer

Archangel Lightworks; Oxford; Hybride; GBP 55 000 - 85 000; Plein temps

Résumé du poste

Archangel Lightworks in Oxford seeks an Optical Engineer to design and assemble optical subsystems for laser communications in demanding environments. You will move from requirements to field testing, collaborating with the Product Technical Lead and engineering team.

You will model performance, run trade studies, and lead subsystem development, while managing suppliers and performing hands-on lab and breadboard testing to validate designs. Periodic travel may be required.

Qualifications

• Experience defining requirements on optical systems and performing trades studies.
• Hands-on lab experience designing and carrying out tests for optical systems.
• Experience with photonic components and lasers, detectors, modulators, and fibre/free-space optics.
• Desirable: high power lasers, optical alignment procedures, and safety requirements.

Responsabilités

• Design of laser communication terminal optical/sub-systems for extreme environments
• Requirement definition and trade off analysis for complex optical/photonics systems
• Modelling of optical system performance, optimisation and tolerancing
• Conducting practical breadboard testing to validate modelled data
• Assembling, integrating and testing subsystems
• Supporting system level testing and trials
• Being a subject matter expert for optical and photonic systems
• Managing suppliers of optical and photonic components
• Providing technical leadership of subsystem development projects

About Archangel Lightworks

Archangel Lightworks is a laser communications company building wireless technology. Founded in 2017, we believe that laser communications to and from satellites is a key component of next‑generation infrastructure. Our core product, the TERRA‑M, is a deployable optical ground station with proven capability for space‑ground data transfer. Our team develops and operates products that advance the security and resilience of critical national infrastructure. We value compassion, resilience, curiosity, ownership and integrity. Our start‑up is a fast‑paced and supportive environment, where you can contribute to novel technology with meaningful applications like reducing the Digital Divide. Archangel Lightworks recently closed over £10 million of investment in an oversubscribed Series A funding round. Our company is also supported by the UK Space Agency, the UK’s Department of Science and Technology (DSIT) and the UK Ministry of Defence.

About the job

We’re looking for an Optical Engineer with both design and Assembly Integration and Test experience to join our engineering team and deliver transformative laser communications technology. You will be responsible for the development of our optical subsystems, from requirements definition to testing in the field. In this role, you will work closely with our Product Technical Lead and optical engineering team.

Your responsibilities will include:

• Design of laser communication terminal optical/photonic sub-systems for extreme environments
• Requirement definition and trade off analysis for complex optical/photonics systems, finding the optimal balance of performance against cost
• Modelling of optical system performance, optimisation and tolerancing
• Conducting practical breadboard testing to validate modelled data
• Assembling, integrating and testing subsystems
• Supporting system level testing and trials
• Being a subject matter expert for optical and photonic systems
• Managing suppliers of optical and photonic components
• Providing technical leadership of subsystem development projects

Requirements:

• Experience defining requirements on optical systems, modelling and performing trades studies to inform design selection
• Optical design/analysis experience using Zemax or similar software for design, optimization and tolerancing. (Sequential, non‑sequential desirable)
• Hands‑on experience with photonic components and systems, including lasers (CW and pulsed), optical detectors/receivers, modulators, and fibre/ free‑space optics, with a solid understanding of underlying physical principles and performance trade‑offs
• Hands‑on lab experience designing and carrying out tests for relevant optical systems

Desirable additional skills:

• Experience with electronics for optoelectronic systems, including analogue front‑ends, high‑speed data converters, embedded/FPGAs, and power/EMI/thermal considerations
• Experience with optical or RF communication systems, including modulation schemes, error correction, FPGA/SDR modem implementation, and relevant protocols (e.g. CCSDS, SpaceWire, Ethernet)
• Experience with high power lasers, optical amplifiers, and relevant safety requirements
• Experience with optical instrument calibration and alignment, and procedure definition
• Knowledge of adaptive optics
• Knowledge of space/satellite systems

Location

Our office is based in Osney Mead, Oxford. There may be opportunity to work from home as agreed with your line manager. There may be opportunity for periodic business travel.

What we offer:

• Opportunity to work on advanced optical systems to support a world‑changing vision
• A collaborative and transparent culture with strong links between functions
• Regular socials and weekly company lunch
• Professional development and skills growth within a specialist engineering field
• Competitive salary and benefits package, with equity options in a growing start‑up
• 25 days annual leave allowance plus bank holidays
