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 versatile Engineers to drive the ramp-up and optimization of our high-volume production lines at the Bulim facility. You will design, optimize, and sustain critical manufacturing processes, test systems, and automation infrastructure across key factory domains. Specialization Tracks Test & Test Maintenance (TE): Develop, sustain, and troubleshoot functional test fixtures, automated test equipment (ATE), and test scripts. SMT & Process (SMT Machine / SMT Process): Optimize solder paste printing, high-speed pick-and-place, reflow profiling, and AOI/SPI parameters. Automation & Industrial Engineering (AE / IE): Implement robotic cells, optimize line balancing, cycle times, ergonomic layout, and factory throughput. Debug, Failure Analysis & Rework (Debug / FA / RE): Drive component-level PCBA failure analysis, root-cause 8D investigations, and micro-rework standards. Key Responsibilities · Establish standard operating procedures (SOPs), process windows, and equipment maintenance recipes for new product introductions (NPI) to mass production. · 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). Qualifications & Requirements · 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).

Here's how to pick the right one and stand out in your application.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
