About the role

We’re looking for an R&D Engineer who’s just as comfortable designing high power circuits as they are cranking out CAD for mechanical assemblies. If you love building real things and want to own the entire process of designing, prototyping, testing, and helping us scale from early builds to functional systems, you’ll fit right in. This role touches every corner of engineering: electrical, mechanical, thermal, systems, manufacturing, and software. Fusion is inherently multidisciplinary, and so is this job.

What You’ll Be Doing

Building and testing HTS (high-temperature superconducting) hardware: including REBCO conductors/cables, high-current power supplies, energy storage systems, cryogenic cooling systems, and integrated test fixtures.
Standing up our R&D lab: benches, instrumentation, vacuum hardware, DAQs, software licenses, and everything in between.
Owning your designs end-to-end: generating CAD and drawings, running FEA, sourcing components, working with vendors, and leading mechanical/electrical assembly.
Hands-on prototyping: CNC machining and fabrication, soldering, wiring, assembling cryostats, working with LN₂, using DMMs/oscilloscopes, characterizing sensors and circuits.
Developing and debugging electronics: from sensing circuits and high-current drivers to embedded control and data acquisition.
Defining requirements and translating tokamak-level system attributes: into subsystem performance metrics.
Solving genuinely hard problems: across physics, engineering, and manufacturing under real-world constraints.
Collaborating closely with a small, multidisciplinary team of physicists, engineers, and technicians: sharing results quickly, making design tradeoffs explicit, and helping shape our technical roadmap.

Maritime Fusion is building fusion reactors for ships and off grid energy markets. En route on this endeavor we’re commercializing High Temperature Superconducting (HTS) cable technology for power distribution while advancing the physics basis of our HTS tokamak to decarbonize global shipping.

Breakeven fusion is coming soon, but the first-of-a-kind (FOAK) reactors will be costly, high maintenance, and have low capacity factors, leading to 5–10x higher electricity cost on the grid. Maritime Fusion is pursuing the most widely accepted approach to fusion, the tokamak, but specifically designed for the marine environment where the challenges that arise between breakeven and a commercially viable energy source are alleviated. The market we're targeting requires 15x less power, lower up-time, and costs the same as alternative fuels but without any emissions. Since fusion does not use highly radioactive fuels or materials – unlike fission – we sidestep the vast majority of regulatory challenges and safety risks associated with nuclear energy. Our team brings over a decade of industry and research experience in plasma physics, nuclear engineering, and electrical engineering with backgrounds at SpaceX, Tesla, Columbia University, and University of Pennsylvania.
