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

Hands-on experience with semiconductor wafer processing techniques, ideally in III-V materials

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

Excellent written and verbal communication skills
