Welcome to Lumentum We're all about harnessing cutting-edge tech to create a brighter, more connected future. We are the leaders in optical and photonic products, working at the intersection of innovation and impact. Here's what we're up to:

Cloud & Networking

• Powering high-speed data transmission for cloud data centers, AI/ML, enterprise systems, and communication services. Think streaming, gaming, and next-gen tech—we make it happen.

At Lumentum, we're committed to collaboration, inclusivity, and empowering our team to shine. Together, we're shaping the tech of tomorrow while supporting a culture where everyone thrives.

Why You'll Love This Role

We are seeking an experienced Principal Designer specializing in the design, development, and optimization of Indium Phosphide (InP)-based photodiodes and photonic integrated circuits (PICs). The ideal candidate will play a pivotal role in defining and executing advanced optoelectronic device architectures for developing world-leading optical components for use in ultra-high data rate systems for cloud data centre, 5G mobile and coherent telecommunications optical fibre networks.

What You'll Be Doing

• Lead the design and simulation of InP-based photodiodes (APDs, PINs) and PICs for high-speed optical communication applications.
• Drive end-to-end development from device concept through layout, fabrication process definition, packaging considerations, and full electrical/optical characterization.
• Collaborate with foundries and internal process teams to define and validate fabrication process flows tailored to PD and PIC performance targets.
• Own and manage the design verification, tolerance analysis, and performance optimization using industry-standard simulation tools (e.g., Lumerical, R-soft, Ansys).
• Work closely with systems, packaging, reliability, and test engineering teams to ensure product integration readiness and reliability compliance.
• Provide technical leadership and mentorship to junior engineers and designers.
• Contribute to intellectual property development, including patents and technical publications.
• Stay abreast of emerging InP material systems, novel device structures, and competitive photonic integration technologies

What We're Looking For

Education:
Master's or PhD degree in Physics or Electrical Engineering or a related field.

Experience:
Minimum 10 years of applicable experience in the field of semiconductor optical device design, test and/or fabrication.

Skills:

• Strong background in physics, electronic/electrical engineering or a related discipline
• Specific relevant areas of previous experience include semiconductor materials and devices, semiconductor lasers, semiconductor optical amplifiers (SOA), optical modulators, detectors, photonic integrated circuits (PIC), PIC design software, microwave/millimeter-wave RF, and 10/40/100G circuitry.
• Optoelectronic component/wafer processing (essential)
• Ability to use scientific and engineering reasoning in a wide range of situations including statistical data analysis

Innovation and ability to drive change in a manufacturing environment to improve product performance

Perks You'll Love

• Flexible time off
• Health and wellness benefits (physical and mental)
• Tuition reimbursement and career growth support
• A workplace built for you: free gym, games room, prayer room
• Subsidized meals, free coffee/tea
• Employee stock options and incentive plans
• A collaborative, innovative, and inclusive culture
