Working at BluGlass, you can expect challenging projects, a collaborative and friendly environment, and competitive benefits. BluGlass continues to expand with new opportunities in Massachusetts. The Laser Engineer will be part of a cohesive team involved in the development, characterization, and manufacturing of advanced laser devices, modules, and systems. Duties: Assemble bench‑top, laser‑based systems; plan, set up, and complete experiments on optical tables, including precision optical alignment; perform optical and electrical assembly and testing; gather, analyze, and present experimental data. Verify the performance of optical components, equipment, systems, and setups; drive improvements to existing and emerging products. Additional Responsibilities (BluGlass focus): Device reliability: design and execute reliability test plans (HAST, HTOL, thermal cycling, vibration), develop test matrices, define pass/fail criteria, and own lifetime projections for laser devices. Failure analysis: lead root‑cause investigations using optical/electrical diagnostics, microscopy, materials characterization, and structured problem‑solving; implement corrective and preventive actions. Data analysis and tooling: perform advanced data analysis using Python and Power BI; build scripts and dashboards; develop code to automate data ingestion, processing, modeling, and reporting; maintain version‑controlled analysis pipelines. HAST and lifetime modeling: plan accelerated stress testing; apply acceleration models and statistical methods (e.g., Weibull/Log‑normal) to estimate device life; document assumptions and confidence intervals. Materials and device physics: apply materials science and semiconductor laser fundamentals (III‑nitride, epitaxy, defects, thermal management) to interpret performance, guide experiments, and inform design changes. Tooling and fixtures: conceive new designs for test fixtures, jigs, and custom tools; collaborate with mechanical engineers on CAD, tolerances, and manufacturability; oversee build and validation. Electrical engineering: design, simulate, and bring up control systems (auto control/feedback loops, drivers, interlocks); design PCBAs for instrumentation and control; perform schematic capture, layout reviews, and bench validation. Equipment ownership: maintain, debug, and refurbish used equipment (optical/electrical test sets, environmental chambers, motion systems); create maintenance procedures and calibration plans; nice‑to‑have experience restoring legacy tools. Operate and maintain a variety of optical, test, and analytical instruments: Optical spectrum analyzers, power meters, beam profilers, interferometers, and high‑speed photodiodes. Oscilloscopes, SMUs, LCR meters, RF sources, environmental chambers, thermal platforms, motion/positioning stages. Deliverables: Clear reports, presentations, and dashboards summarizing methods, data, analysis, and recommendations; training and support to internal personnel. Location: Role based in NH, with time split between lab and manufacturing facilities; occasional travel to partner or supplier sites as needed. Requirements: PhD in Science or Engineering (Physics, Materials Science, Electrical Engineering, Optics), preferably with 5+ years of directly related industry experience; candidates with a Master’s plus significant experience are encouraged to apply. Design experience with lasers and complex optical systems; strong preference for semiconductor and fiber/UV laser experience. Experience with optical metrology and hands‑on work with optical/electrical test equipment. Proven track record in device reliability testing, failure analysis, and lifetime modeling (including HAST/HTOL). Strong programming skills (Python) and data visualization (Power BI); ability to write robust, documented code for data processing and analysis. Electrical engineering foundations: controls/feedback, power electronics for laser drivers, safety interlocks; PCB design familiarity. Ability to collaborate cross‑functionally; excellent communication and organizational skills; proactive problem‑solving and ownership mindset. Compensation and Benefits: Competitive salary commensurate with experience and location. Eligible for annual discretionary bonus and equity awards, as applicable. Benefits include paid vacation and sick time; paid holidays; medical, dental, and vision insurance with HSA/FSA options; short‑ and long‑term disability; paid life and AD&D; 401(k) with company matching; Employee Stock Purchase Plan (ESPP); tuition reimbursement; Employee Assistance Program (EAP); parental bonding leave; backup care programs. Benefits eligibility may vary by schedule and program. Pay: $85,000.00 - $100,000.00 per year Benefits: 401(k) 401(k) matching Dental insurance Flexible spending account Health insurance Health savings account Life insurance Paid time off Relocation assistance Vision insurance Experience: Semiconductor: 1 year (Required) Work Location: In person
