Shift Process Integration Engineer (Chip R&D / NPI / Wafer Fab Semiconductor)
Lumentum is seeking a junior Process Integration Engineer to join our Chip R&D team at our Caswell site in Northamptonshire, UK. In this role, you will contribute to the development and management of wafer fabrication processes for indium phosphide (InP)–based semiconductor optical components.
This is an on-site, shift-based position 4 days on, 4 days off.
Role Overview
The Chip R&D team is responsible for developing and introducing into production advanced photonic devices, including lasers, modulators, receivers, and photonic integrated circuits (PICs) for cloud and networking applications.
As a Process Integration Engineer, you will play a key role in translating device designs into manufacturable, high-performing semiconductor chips. This requires close collaboration with cross-functional engineering teams to solve complex technical challenges with tangible commercial impact.
Key Responsibilities
-
Integrate wafer fabrication processes to deliver new InP-based products, including coherent and direct detection photonic components
-
Optimize existing wafer fab processes to improve yield, cost, and cycle time
-
Develop and maintain process flows and documentation within the MES system
-
Monitor and evaluate product performance throughout the development cycle
-
Use analytical tools (e.g., SEM) to investigate and improve process performance
-
Develop new process modules and ensure scalability for high-volume manufacturing
-
Support the transfer of new processes and products into production
-
Apply Six Sigma methodologies (e.g., FMEA, capability analysis, design for manufacturability/yield) for process and product improvement
-
Present process data and statistical analyses to support manufacturability decisions
-
Act as the key interface between design, operations engineering, and manufacturing teams
-
Serve as the process expert for products, including post-transfer support in production
Skills and Experience
Essential Qualifications & Experience
-
Degree in Physics, Physical Chemistry, Materials Science, or a related field (relevant industry experience may be considered in lieu). Applications welcome from fresh Phd candidates

Knowledge in several of the following areas:
-
Epitaxy
-
Lithography
-
Wet and dry etching
-
Dielectric and metal deposition
-
Ion implantation and diffusion
-
Experience in process integration and development of process flows
-
Strong problem-solving skills and ability to manage complex engineering activities
Desirable Experience
-
Knowledge of direct bandgap semiconductor materials
-
Experience in a semiconductor manufacturing or wafer fab environment
Key Competencies
-
Strong analytical and scientific reasoning skills
-
Familiarity with statistical analysis tools (e.g., JMP)
-
Effective team collaboration and organizational abilities
-
Technical leadership and ownership mindset
