Lead Machinist (Advanced Alloys & Robotics)

Lead Machinist (Advanced Alloys & Robotics) Stamford, CT 06902 Part-time, Full-time Part-time, Full-time About Supercool Metals Supercool Metals is a deep tech start‑up based in Connecticut that develops advanced metallic materials and manufacturing processes. We are pioneering high‑strength, lightweight alloys and novel fabrication techniques to unlock the next generation of robotic actuators and gear drive systems. Our mission is to push the boundaries of motion‑control hardware so that robots can perform tasks with unprecedented efficiency and agility. Role overview We are hiring a Lead Machinist who thrives in a high-trust, high-ownership machine shop. You will build high-value, low-volume components and precision metallic tooling for robotics and automation, working with novel amorphous alloys and hardened materials. This role is for a hands-on expert who can take a part from print to finished hardware and improve the process along the way. What you will do Own jobs end-to-end: interpret engineering intent, plan the process, select tooling, run setup, machine, deburr/finish, and complete final inspection.

Multi-axis CNC execution:

set up and run complex multi-axis CNC work in a low-volume / high-mix environment; prove out programs and refine feeds/speeds for difficult materials.

EDM for precision geometries:

run wire and/or sinker EDM for features that require extreme accuracy, fine finishes, or challenging internal geometry.

Manual machining for critical tooling:

operate manual mills, lathes, grinders for fixtures, one-off tooling, and mold components where judgment matters.

Precision mold-making:

machine and finish complex metallic parts to high tolerances; manage parting lines, surface finish requirements, venting features, and alignment details as applicable.

Metrology and quality:

measure and document results using CMM and/or optical systems plus standard inspection tools (mics, indicators, gauge pins, bore gauges, calipers as needed).

Partner with engineering:

provide direct feedback on manufacturability, tolerance strategy, and design improvements to increase yield, repeatability, and cycle time.

Run a reliable shop:

basic preventative maintenance, tooling organization, inventory awareness, and a clean, safe workspace.

Required qualifications:

Deep machining range: demonstrated experience across CNC programming/setup/operation and manual machining.

Multi-axis CNC capability:

strong experience setting up and running multi-axis CNC work and holding tight tolerances on complex geometries.

EDM experience:

wire and/or sinker EDM proficiency (preferred).

Mold/tooling background:

prior work on metallic molds, dies, or high-precision tooling (preferred). Print and GD&T fluency: confident reading drawings, tolerances, and GD&T; able to clarify intent quickly and correctly.

High ownership:

manage priorities independently, communicate clearly, and keep work moving without constant oversight.

Nice to have:

CAM experience, comfort extracting information from 3D models, and editing toolpaths at the machine when appropriate. Experience machining hardened steels and difficult-to-machine alloys. Experience building fixtures for repeatable precision in short runs. Why join us No repetitive commodity production: the work is varied and technically demanding. Materials + robotics in the same role: you will machine tooling and components that directly enable next-generation robotic hardware.

Forefront of technology:

At Supercool Metals you'll be at the forefront of developing next‑generation actuation hardware using cutting‑edge materials and processing technology.

Real ownership:

if you like being trusted to solve problems, improve processes and innovate, you will have significant opportunities to grow. Salary is commensurate with experience Ready to build high-performance hardware for robotics? Apply with a short note on the most difficult part you have machined, tolerances, material, tools and processes you used.
