Principal Optical Engineer | Next Gen Optics | London - Onsite | £85k - £110K
We're looking for an experienced Principal Optical Engineer to lead the development of advanced optical systems for an innovative next-generation hardware platform.
This is a highly technical, hands-on role where you'll own the optical architecture, design, and development from prototyping, design, development and integration to manufacturing.
If you enjoy solving complex optical engineering problems and want to lead the development of a next-generation product. This is the role for you.
Responsibilities:
- Own the optical architecture and technical direction of a next-generation product and future technology roadmap.
- Design, model, simulate and optimise optical systems using Zemax.
- Lead optical system development from early prototypes through design verification & validation and production.
- Develop optical performance budgets, tolerance analyses, error budgets and calibration strategies.
- Balance performance and engineering capabilities with manufacturability, cost, reliability, packaging, thermal behaviour and scalability.
- Work hands-on in the laboratory to validate designs and correlate simulation with measured performance.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
