Let’s Work Together

Open Roles:

  • Location: San Francisco, CA
    Experience: 2–5 years

    Lightmill is building a radically new manufacturing process with the goal to change how machined components are made. We’re a small, fast-moving team tackling hard mechanical problems and building real hardware every day.

    We're looking for a Founding Mechanical Engineer who wants to design and build the physical foundation of the company.

    What You'll Do:

    • Design and prototype mechanical systems for next generation manufacturing equipment

    • Build, test, and iterate rapidly on prototypes

    • Own mechanical design from concept through production

    • Work across disciplines including optics, electronics, and manufacturing

    • Set up early mechanical engineering processes and tooling

    • Solve a wide variety of technical challenges as the company grows

    Because we're a small team, you'll have significant autonomy and the opportunity to influence both the product and the company.

    We're Looking For Someone Who:

    • Has 2–5 years of hands-on mechanical engineering experience

    • Is a generalist who can wear many hats and learn quickly

    • Takes ownership and moves projects forward independently

    • Wants to work hard (50–70 hours per week regularly)

    Nice to Have:

    • Experience designing for precision alignment or opto-mechanical systems

    • Familiarity with rapid prototyping, machining, or fabrication

    • Experience with hardware startups or small teams

    Why Lightmill:

    • Develop a technology that will radically change how hardware is developed and manufactured

    • Be one of the first employees and help define the company

    • High ownership and fast feedback loops

    • Build something meaningful from the ground up

    To Apply:

    Send your resume and a description of a project that you’ve worked on to careers@lightmill.us.

    Pictures or slides are a bonus.

    Lightmill is building a radically new manufacturing process with the potential to change how machined components are made. We’re a small, fast-moving team tackling challenging mechanical problems and building real hardware every day.

    We’re looking for an engineering intern who wants real ownership, not busywork.

    As a Lightmill intern, you will own a subsystem end-to-end: design it, build it, test it, and integrate it into our system. You’ll work directly with the founding team and contribute to technology that will define a major manufacturing category.

    What you’ll do:

    • Design, prototype, and test a critical subsystem

    • Run experiments and iterate quickly based on real data

    • Refine a solution and integrate your work into new and existing laser systems

    • Move fast and solve difficult engineering problems alongside a small engineering team

    You might be a fit if you:

    • Love prototyping and building real mechanical systems

    • Take initiative and ownership

    • Figure things out without waiting for instructions

    • Want experience inside a fast-moving early-stage startup

    • Are studying Mechanical Engineering, Mechatronics, Manufacturing Engineering, Robotics, or a related field

    If you want to spend a summer developing cutting edge technology with a small team that moves fast, we’d love to hear from you.

    To Apply:

    Send your resume and a short note about something you’ve built to careers@lightmill.us.
