SALARY
$180,000 per year
About the role
- Lead mechanical design and layout of laser diode packages and various subcomponents
- Design and optimize optical subassemblies (laser, lens system, isolator/grating, fiber coupling) to achieve submicron alignment with high coupling efficiency and long-term stability
- Develop package architectures integrating thermal electric coolers, submounts, hermetic housings, lids, getters, and fiber attach features
- Ensure compatibility with active alignment processes, including fixture design, alignment tolerancing, and drift control during solder reflow or epoxy cure
- Perform thermal and mechanical design analysis: FEA, thermal modeling and evaluate impact on wavelength shift
- Design for high thermal power density and ensure adequate thermal margin
- Design for hermetic sealing approaches meeting leak rate targets
- Select and qualify materials and attachment methods
- Partner with suppliers to evaluate component capability, process maturity, and long-term reliability risks
- Drive design-for-manufacturability (DFM) to enable high-yield, scalable production
- What You Will Have (Basic requirements):Masters in Mechanical Engineering
- At least 10+ years of industry R&D experience with mechanical design of fiber-coupled optoelectronic packages developed and transferred to manufacturing environments
- Demonstrated experience with optical alignment of components to submicron tolerances, designing for high thermal power density
- Proven ability to design for submicron stability over life
- Mechanical design using Mech software package/s with finite element analysis (FEA)
- Strong background in FEA modeling to calculate stress/design from CTE mismatch, optic misalignment, thermal limits, etc.)Knowledgeable of various optical components (e.g., gratings, mirrors, lenses), stable attachment methods (e.g., epoxy and solder based)
- Experience with New Product Introduction (NPI) methodology: design, verification, qualification, release to manufacturing
- Strong communication skills with suppliers, customers, and cross-functional internal teams
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
