Laser Laboratory Engineer – Chip Verification
Optoelectronics | Photonic Integrated Circuits (PICs) | New Product Introduction (NPI)
Join Lumentum and help develop the next generation of photonic technology
Lumentum is looking for a Laser Laboratory Engineer to join our Chip R&D team in Northamptonshire.
This is an exciting opportunity to work with advanced photonic integrated circuits (PICs) and semiconductor devices that enable the world’s fastest optical communication networks, AI infrastructure, and cloud data centres.
Working as part of a collaborative global R&D team, you’ll carry out experimental testing and characterisation of cutting-edge photonic devices, helping bring new technologies from research into successful New Product Introduction (NPI).
This role is ideal for someone at the beginning of their engineering career who enjoys practical laboratory work and wants to develop specialist expertise in photonics and optoelectronics. We welcome applications from candidates who have gained hands-on laboratory experience through their degree, research projects, industrial placements, or internships.
What You’ll Be Doing
As a Laser Laboratory Engineer, you’ll support the development and verification of advanced photonic devices through laboratory testing, data analysis, and performance investigation.
Your Responsibilities Will Include
- Perform optical, electrical, and RF characterisation of photonic devices and photonic integrated circuits (PICs).
- Test lasers, modulators, detectors, and other III-V semiconductor devices using advanced laboratory equipment.
- Set up and improve manual, semi-automated, and automated laboratory test systems.
- Support the development of experimental hardware and software for device characterisation.
- Collect, analyse, and interpret experimental data to evaluate device performance.
- Support performance investigations and failure mode analysis.
- Work closely with Chip Design, Product Engineering, Reliability, Process, and Test Engineering teams throughout product development.
- Maintain accurate laboratory records and contribute to technical reports.
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.
