Mechanical Integration & Coil-Fabrication Lead

Turn field-coil geometry and machine requirements into repeatable hardware, fixtures, interfaces, and an executable fabrication cadence.

Planned full-timeSan Francisco, CA · On-site

Apply for this role

The role

Build the first machine with us.

This role would own the mechanical path from coil geometry to a buildable, measurable, and serviceable experimental assembly. The immediate focus is the first pulsed-coil articles: winding strategy, insulation, structural support, tooling, metrology, and integration with the surrounding high-voltage, vacuum, and diagnostic systems.

You would work directly with founder Joe Finberg and the other first technical hires. The right person is comfortable moving between analysis, CAD, vendor conversations, shop-floor problem solving, inspection, and hardware acceptance—not simply handing drawings across an organizational boundary.

What you would own

Translate electromagnetic loads and coil geometry into manufacturable windings, insulation systems, supports, and interfaces.
Own fixtures, tooling, tolerances, metrology, assembly sequencing, and configuration control for early coil articles.
Develop structural and thermal analyses appropriate to short-duration, high-force pulsed operation.
Select materials and processes with attention to dielectric performance, fatigue, vacuum compatibility, serviceability, and lead time.
Decide what should be built in-house and what should be placed with vendors; qualify both paths with explicit acceptance criteria.
Lead fit-up, inspection, failure investigation, rework, and integration across mechanical, power, controls, and diagnostics interfaces.

What we are looking for

Experience owning mechanically demanding hardware from detailed design through fabrication, inspection, assembly, and test.
Strong CAD, drawing, tolerance, materials, and manufacturing-process judgment.
Experience designing fixtures and turning one-off builds into controlled, repeatable processes.
A record of resolving real fabrication or integration failures through measurement and disciplined root-cause work.
Comfort working directly with machinists, composite or coil shops, technicians, and specialized vendors.

Especially useful

Experience with pulsed magnets, wound coils, high-field structures, vacuum hardware, or high-voltage insulation.
Familiarity with FEA for transient electromagnetic, structural, and thermal loads.
Experience building an early-stage hardware supply chain and inspection process.

Please answer using only public or non-confidential experience. Do not submit proprietary information belonging to a current or former employer.

01 · Describe a coil, magnet, vacuum, or high-force pulsed assembly you carried from geometry through fabrication and commissioning.Explain your direct ownership, the most important failure or surprise, and what changed in the design or process.02 · Lay out the build and acceptance path you would use for a first pulsed-coil article.Address analysis, materials, winding, insulation, fixtures, metrology, vendor-versus-in-house choices, and proof that it is ready to pulse.03 · Which mechanical interface would you retire first in an integrated pulsed machine, and why?Describe the test article, measurements, and acceptance threshold you would use.
