Process Engineer

PROCESS ENGINEERMesh Optical Technologies was founded on the belief that optical photons will be at the center of advanced technologies in the coming century. Making advanced technology ubiquitous means building at scale, and that's exactly what we're doing at Mesh.Keeping our production tools running and our processes stable is what turns engineering designs into product at volume. We are seeking a Process Engineer to own the day-to-day operation, uptime, and optimization of the packaging and assembly tools on our production floor.RESPONSIBILITIESOwn day-to-day operation and uptime of production tools including flip-chip bonders, plasma cleaners, de-flux tools, automated handlers, dispense tools, and wire bondersDesign production processes from the lab bench through proof of concept and production rampMonitor and control key process parameters, ensuring repeatability, equipment calibration, and adherence to manufacturing specsTroubleshoot tool and process issues in real-time, minimizing downtime, and driving fast root-cause resolutionCollaborate with engineering teams to stabilize and improve process flows for die attach, bonding, cleaning, and packagingAnalyze production data and yield trends, identifying opportunities for process optimization and defect reductionPush process yields above 99.9% and thermal-cycle reliability beyond 1000 cyclesSupport factory scaling efforts, qualifying new tools and recipes that enhance unit throughput and yieldQUALIFICATIONSB.S. or M.S. in Materials Science, Mechanical Engineering, Electrical Engineering, Chemical Engineering, or a related fieldStrong troubleshooting skills with experience maintaining high-uptime operation of precision manufacturing toolsHands-on experience in semiconductor packaging, assembly, or advanced manufacturing environmentsFamiliarity with equipment and processes such as flip-chip bonding, wafer processing, plasma cleaning, and wire bondingAbility to interpret process documentation, equipment specifications, and production data to drive consistent outputComfortable working in a cleanroom or controlled manufacturing environment with cross-functional engineering teamsWillingness to work extended hours and weekends as neededPREFERRED EXPERIENCEDirect experience qualifying or operating production equipment in a high-volume production environmentKnowledge of sub-µm die-bonding, wafer prep, and materials used in advanced packagingFamiliarity with statistical process control and root cause analysis methods2+ years of experience in process development or yield improvement for optical, photonic, or microelectronic devicesCOMPENSATION AND BENEFITS:Pay range:Process Engineer: $120,000.00 - $140,000.00/per yearTitle and base salary are determined on a case by case basis commensurate with experience and merit.In addition to base salary, compensation for this role includes:Eligibility for long-term incentives including company stock options and discretionary bonuses awarded for exceptional achievements.Comprehensive medical, vision, and dental insurance with significant cost covered by the company for yourself and dependents.Paid parental leave and flexible PTO (3 weeks accrued vacation and 10 company holidays per year).401(k) retirement plan access.Relocation assistance to sunny Los Angeles.
