Job description

About Lumilens

At Lumilens, we are building the essential photonics infrastructure that will drive tomorrow’s AI supercomputing. From chip-to-chip optical interconnects to scalable photonic engines, Lumilens is ushering in a new era of computing that is faster, cooler, and dramatically more efficient. We’re a well-funded startup backed by Mayfield and led by veterans who have built and scaled some of the industry’s most transformative technologies.

About the Role

We are seeking hands-on Process Engineers to support our volume manufacturing ramp-up at our Bulim facility. In this role, you will be responsible for process development, qualification, yield optimization, and continuous improvement across microelectronics packaging, optical module assembly, and high-precision automation lines.

We are hiring across multiple domain specializations:

• Die Attach (DB / Die Bond)

• Wire Bond (WB)

• Active Alignment (AA / Optical Alignment)

• Process Engineering – Overall / Integration

Key Responsibilities

• Process Setup & Optimization: Establish robust process windows, parameter recipes, and standard operating procedures (SOPs) for assigned production modules (DB, WB, AA, or End‑to‑End Line Integration).

• Yield & Defect Reduction: Monitor line yield metrics, lead 8D root‑cause failure analysis (FA), and implement corrective actions for recurring process/equipment defects.

• NPI to Mass Production: Partner with NPI and Equipment Engineering to qualify new tooling, materials (epoxies, substrates, bonding wire), and automation platforms for high‑volume ramp.

• Statistical Process Control: Apply SPC, DOE, FMEA, and Cpk analysis to drive process stability, cycle time reduction, and cost‑efficiency initiatives.

• Cross‑Functional Collaboration: Work closely with Manufacturing Operators, Quality Engineers, and Maintenance Technicians to resolve line stops and uphold quality standards.

Qualifications & Requirements

• Education: Bachelor’s Degree or Diploma in Mechanical, Electrical/Electronic, Mechatronics, Materials Science, or Manufacturing Engineering.

• Experience: 2+ years of relevant process engineering experience in semiconductor packaging, microelectronics, surface‑mount technology (SMT), or camera/optical module manufacturing.

• Domain Expertise (one or more of the following):

• Technical Skills: Proficiency in SPC tools (JMP, Minitab), GD&T, and structured problem‑solving methodologies (8D, 5‑Why, Fishbone).

• Work Arrangement: Willingness to work on‑site at the Bulim plant and support operational needs during ramp‑up phases.

Benefits

• Competitive salary and benefits

• Opportunities for career advancement

• Work with a world‑class team solving cutting‑edge challenges

• Collaborative and innovative work environment

Lumilens is committed to building a diverse and inclusive workplace. We are proud to be an equal opportunity employer.
