Shift Process Integration Engineer (Chip R&D / NPI / Wafer Fab) – Lumentum
We’re passionate about what we do, committed to customer focus, and thrive on innovation. At Lumentum, we believe in bringing energy, diversity, and collaboration to drive growth—join a team full of over-achievers and take your career to new heights!
About the Role
Lumentum is seeking a junior Process Integration Engineer to join our Chip R&D team at our Caswell site (Northamptonshire, UK). In this on-site, shift-based position (4 days on, 4 days off), you will support the developing and scaling of wafer fabrication processes for indium phosphide (InP)-based optical components.
The Chip R&D team focuses on **. . .
† Designing and producing advanced photonic devices:
- Lasers
- Modulators
- Receivers
- Photonic Integrated Circuits (PICs) . . informed by cutting-edge cloud and networking applications.
As a Process Integration Engineer, you’ll:
- Bridge the gap between device design and manufacturability (turning complex specs into high-performing chips).
- Partner with cross-functional teams (engineers, manufacturing, and operations) to solve critical technical challenges with commercial impact.
Key Responsibilities
Process Development & Integration
- Work across wafer fabrication to integrate and optimize processes for new InP photonic products, including coherent/direct detection components.
- Refine processes to boost yield, reduce costs, and accelerate time-to-market.
- Develop and document process flows within the Manufacturing Execution System (MES).
Analytical & Problem-Solving Roles
- Monitor product and wafer performance throughout the development lifecycle, using SEM and other analytical tools to troubleshoot inefficiencies.
- Introduce new process modules, ensuring scalability to suit high-volume manufacturing demand.

- Implement Six Sigma methodologies:
- FMEAs (Failure Modes & Effects Analysis)
- Design of Experiment (DOE)
- Process capability analysis
- Design for Manufacturability/Design for Yield (DFM/DFY).
Collaboration & Communication
- Serve as the bridge between design, engineering, and manufacturing.
- Communicate process data and statistical analysis results to stakeholders for commercial decision-making.
Requirements
Essential
- Undergraduate degree in:
- Physics, Physical Chemistry, Materials Science
- or equivalent (technical experience could replace formal qualifications).
- Hands-on experience with:
- Semiconductor wafer processing techniques
