    About Optopax

    Optopax is a Silicon Valley–based design and OEM manufacturing company delivering integrated AI imaging solutions—from concept through production. We specialize in AI-enabled camera modules, precision optics spanning UV to LWIR, and custom embedded systems for robotics, industrial vision, submersible imaging, biomedical devices, AR/VR, and optical computing. We are a small, highly technical team headquartered in San Jose, CA, building real hardware that ships.

    About the Role

    We are looking for a hands-on Mechanical / Electro-Mechanical Engineer who can take loosely defined requirements from optics and test teams and turn them into robust, manufacturable systems. This is not a CAD-only role and not a pure manufacturing role. You will design, build, assemble, test, debug, and iterate optical fixtures, camera test stations, and electro-mechanical subsystems—often under tight timelines. This role is ideal for someone who enjoys being equally comfortable in CAD, at the bench, and on the shop floor, and who understands how design decisions affect assembly, yield, reliability, and cost.

    What You'll Do

    Design integrated electro-mechanical and opto-mechanical systems for camera modules, optical test fixtures, and precision assemblies

    Translate specifications from optics, test, and embedded teams into manufacturable hardware designs

    Create detailed 3D CAD models and production drawings (Fusion 360 preferred)

    Apply DFM/DFA, GD&T, and tolerance stack-ups to ensure repeatable builds

    Design and integrate multi-axis motion systems (linear stages, actuators, motors, encoders)

    Build and evaluate prototypes using 3D printing, CNC machining, and sheet-metal fabrication

    Assemble and test precision mechanical and optical assemblies, including camera modules and fixtures Develop and run test setups, collect data, and document results

    Source components and work directly with vendors, machine shops, and optical suppliers

    Support transition from prototype to low-volume and production builds

    Collaborate closely with optics, firmware, electronics, and manufacturing teams

    What You'll Bring

    Required

    Degree in Mechanical Engineering, Mechatronics, or a closely related field with 1-2+ years of professional experience

    Strong CAD skills (Fusion 360 preferred)

    Strong experience with DFM/DFA, GD&T, and tolerance analysis

    Proven hands-on prototyping and fabrication experience (CNC/manual machining, 3D printing, sheet metal, fixtures, jigs)

    Experience integrating electro-mechanical and motion systems

    Comfortable working with small, precision mechanical and optical assemblies

    Experience using and integrating microcontrollers and SBCs into testing platforms

    Software experience (Python and/or C++) for test or automation

    Lab-oriented mindset with attention to detail and practical problem solving

    Clear written and verbal communication skills

    Nice to Have

    Familiarity with common optical and motion vendors (e.g., Thorlabs, Edmund Optics, Newport)

    Experience designing optical test fixtures or camera test systems

    Control system integration (PLCs, motion controllers, sensors)

    FEA experience (static, thermal, modal, or nonlinear)

    Experience working with external manufacturers and machine shops

    Exposure to early-stage product development and rapid iteration cycles

    Why Optopax?

    Work at the intersection of optics, AI, and embedded systems

    Own hardware from concept through manufacturing

    See your designs quickly turn into working systems used in real-world applications

    Join a small, high-impact team where engineering decisions matter
