Mechanical Engineer

About Bridge Neurotech

Bridge Neurotech is building a non-invasive functional ultrasound imaging (fUSI) platform with AI-based neural decoding for brain-computer interface applications. We are a seed-stage neurotechnology company developing technology that has the potential to transform how clinicians monitor, diagnose, and treat neurological conditions.

About the role

We are looking for a Mechanical Engineer who can reason and design from first principles, then turn those designs into physical parts. Almost nothing we build can be bought, so we build our own as one-off or low-volume production. You will be part of the team that owns that work: design it, build it, test it.

This is a hands-on lab role with significant breadth: CAD, prototype development, fixture design, testing, failure analysis, and everything in between. You will be AI-enabled: scripting your own tools, crossing traditional discipline boundaries, and still being the person who actually makes the thing. We expect you to use AI coding tools to develop automations and bespoke tools to improve efficiency.

What you’ll do

• Design and iterate mechanical parts in CAD, for example housings, mounts, fixtures, enclosures, and lab hardware, with attention to first principles, materials, and design for manufacturing.

• Build the test infrastructure that makes our engineering measurable, and benchtop rigs for hardware bring-up.

• Build the parts you design in house: run and maintain our 3D printers and desktop CNC, dial in materials and profiles, and manage the queue. Build the workflows and automation around them, for example scripted slicing and job submission, CAM setup, revision control, and part tracking.

• Outsource the parts you cannot build in house, including quoting and vendor management.

• Develop processes for low-volume part production, for example mold design and fabrication, casting, potting, bonding, finishing, and the jigs and fixtures those processes need.

• Do first-order engineering analysis before you build, then follow it with simulation.

• Do the hands-on assembly that makes hardware real: precision assembly of delicate parts, basic cable and harness work, and careful integration of mechanical, electrical, and acoustic components.

• Write the Python that glues the shop together: CAD scripting and plugins, automation, instrument control, data logging.

• Work directly with our imaging scientists and research team to understand how each part will actually be used.

Who you are

Required

• 3 to 5 years of mechanical engineering experience taking hardware from concept through prototype builds.

• Bachelor’s degree in mechanical engineering, a closely related discipline, or equivalent experience.

• Strong proficiency in CAD: parametric modeling, assemblies, drawings, GD&T basics, and design for manufacturing.

• Solid engineering fundamentals you can apply on a whiteboard: statics and beam mechanics, basic heat transfer, basic fluids, and tolerance stack analysis.

• Experience working with electrical engineers on mechanical and electrical integration: connector selection, board outlines, and test fixturing.

• Hands-on 3D printing experience, for example tuning, troubleshooting, and repair, plus the judgment to know when a part should be printed, machined, or molded.

• Strong shop skills: comfortable with hand and power tools, post-processing and finishing parts, and assembling precision hardware.

• Fluent with AI coding tools and comfortable using them to build your own working tooling, including scripting your CAD package when it lacks a feature you need.

• A bias toward building, testing, and improving over designing to completion first.

• Self-directed and self-motivated, with the ability to execute on a goal rather than a step-by-step guide.

• A track record of taking hardware from an ambiguous requirement to a working part, with evidence such as shipped products, personal projects, a home shop, or other work that shows you build things unprompted.

• Strong written and verbal communication, including clear drawings, build documentation, test plans, and the ability to explain tradeoffs to a mixed audience

Nice to have

• Experience designing small wearables or body-contacting hardware, where space, weight, and comfort drive the design.

• CNC machining experience, for example CAM programming, fixturing, workholding, and running a mill or lathe yourself.

• Soldering skills, both board-level (fine-pitch and through-hole) and wire, plus clean cable and harness assembly.

• Experience with metrology, 3D scanning, or FEA.

• Prior work in a startup or small team, or other evidence of thriving without much scaffolding.

What we offer

• Real ownership of the mechanical hardware this company runs on, with a direct path to growing into a senior or lead role as the team scales.

• Meaningful equity in a seed-stage company.

• Mentorship from our product design lead, and direct collaboration with our imaging scientists and research team.

• Hybrid office policy, on-site 3 days, work from home 2 days.

• Excellent medical benefits and a 6% match 401(k).

Bridge Neurotech is an equal opportunity employer. We encourage candidates of all backgrounds to apply.
