Senior Silicon Photonics Engineer (WDM)
💰 £70k–£90k + bonus | 📍 Leeds (onsite) | Permanent, full-time
A UK deep-tech scale-up is building programmable silicon photonic technology that performs compute directly within the data path. That cuts the cost of moving data around and opens up new capability for AI, cybersecurity, and scientific workloads. It's a small, highly technical team working on genuinely hard problems, with real silicon at the end of it.
They're hiring a Senior Silicon Photonics Engineer to own the wavelength division multiplexing architecture for their multi-wavelength, high-speed photonic interconnect and compute platform. If the WDM plan is right, everything downstream works, so this is a role that shapes the product.
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we're after
- MSc or PhD in photonics, electronic engineering, physics or similar
- Silicon photonics or integrated optics design experience, with successful tapeouts
- Strong WDM link design, resonant devices, and thermal tuning knowledge
- Hands-on AWG, echelle grating or comparable multiplexer design and characterisation
- Photonic circuit simulation, foundry PDKs, and layout verification flows
- Bonus points: Lumerical, Cadence, Python/MATLAB, CW-WDM MSA familiarity
What's in it for you?
- 💡 Ownership of a core architecture, from spec to first silicon
- 🎯 Annual performance-based bonus
- 🏥 Comprehensive healthcare plan
- 🏦 Employer-contributed pension
- 🌴 Generous time off
- 🚀 Start-up pace, where your design decisions go straight into silicon

Your very own career expert that helps elevate your application to the next level.
You'll define the wavelength plan, channel spacing, and power budget. You'll then weigh up AWG against micro-ring approaches on power, yield, and control complexity. From there, it's simulation across process, wavelength, and temperature corners, followed by foundry-ready layouts and test structures.
You'll work closely with device, PIC, analogue front-end, layout, and packaging engineers. You'll own foundry signoff for WDM functions and get stuck into first-silicon characterisation and debug.
If you've taped out photonics and would rather set the architecture than inherit it, let's talk. Apply here or drop me a message.
