Lumilens is building photonics infrastructure for AI supercomputing, developing chip-to-chip optical interconnects and scalable photonic engines. The company is Series B funded and led by veterans from transformative technology companies.
You will drive the ramp-up and optimization of high-volume production lines at the Bulim facility, designing, optimizing, and sustaining critical manufacturing processes, test systems, and automation infrastructure. The role offers specialization tracks across multiple domains:
Test & Test Maintenance: Develop, sustain, and troubleshoot functional test fixtures, automated test equipment (ATE), and test scripts.
SMT & Process: Optimize solder paste printing, high-speed pick-and-place, reflow profiling, and AOI/SPI parameters.
Automation & Industrial Engineering: Implement robotic cells, optimize line balancing, cycle times, ergonomic layout, and factory throughput.
Debug, Failure Analysis & Rework: Drive component-level PCBA failure analysis, root-cause 8D investigations, and micro-rework standards.
Key responsibilities include establishing standard operating procedures (SOPs), process windows, and equipment maintenance recipes for new product introductions (NPI) to mass production. You will monitor line yields, track Cpk metrics, and deploy SPC methodologies to eliminate recurring production defects. Partner with NPI, Design, and Quality teams to execute Engineering Change Notices (ECNs) and qualify new tooling or component substitutes. Lead cross-functional problem-solving initiatives using structured methodologies (8D, 5-Why, Fishbone, DOE).
Required: Bachelor's degree in Mechanical, Electrical/Electronics, Mechatronics, Industrial, or Manufacturing Engineering. 2+ years of hands-on engineering experience in high-volume electronics assembly, SMT, PCBA testing, or semiconductor packaging. Practical exposure to at least one primary domain: SMT equipment, ATE/LabVIEW/Python test scripts, PLC programming, or PCBA failure analysis. Strong analytical mindset with experience in SPC, FMEA, and data analysis tools (Minitab, JMP).
