## About Fuse

We are building one of the most potentially consequential companies of the century. Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win.

## About the Role

As a Machinist at Fuse, you're focused on production: taking drawings from engineering and turning them into parts, fast, right, and efficiently. You'll work on a mix of standardized TITAN components and rapid one-offs with tight timelines, operating manual and CNC mills and lathes, writing and optimizing CAM programs, and verifying dimensions to hit tolerances consistently.

Core Responsibilities

- Operate manual and CNC mills and lathes: set up, program, and run jobs from engineering drawings with precision and speed.
- Write and edit CAM programs using Fusion CAD/CAM, NX CAM, or equivalent.
- Select tooling and setups based on part geometry, material, and tolerances.
- Work with materials including stainless steel, PMMA, composites, tungsten alloys, and others.
- Inspect finished parts against engineering drawings and GD&T requirements and communicate issues to engineering.

## Minimum Qualifications

- High school diploma or GED plus 1+ years of professional CNC machining experience, or equivalent education and hands-on shop experience.
- Proficiency with 3-axis or higher CNC and manual mills and/or lathes.
- Ability to read and write CAM code using Fusion CAD/CAM, NX CAM, or equivalent.

## Preferred Qualifications

- 3+ years of professional CNC machining experience.
- Experience with 5-axis mills or multi-axis machines.
- Familiarity with Haas machines.
- CMM programming experience using ZEISS CALYPSO.

## What We Value

- Give a shit. Build things you're proud of.
- Take responsibility. If something is broken and you can fix it, fix it. See things through.
- Move fast. Make decisions, learn quickly, and keep moving forward.
- Think bigger. Simplify relentlessly. Don't default to the safe answer.
- Disagree and commit. The best idea wins. Once a decision is made, we move.
- Desire to win. This is hard. Expect intensity. We are here to win.
- Plan B is to make Plan A work.

Physical Requirements

- Able to stand or sit for extended periods during machine operation.
- Able to lift and carry items up to 25 pounds regularly and occasionally up to 50 pounds.
- Consistent use of required PPE, including eye, hearing, hand, and foot protection.
- Understanding and adherence to lockout/tagout procedures and safe machine operation.

## Benefits

- Medical, dental, and vision coverage.
- Relocation assistance for roles that require it.
- Flexible time off. Take what you need, no accrual tracking.
- 2 weeks of paid time off built into the end of each year, subject to team and business needs.
- 10+ paid holidays.
- Supportive leave of absence policies.
- Paid leave for new parents.

ITAR Requirements To conform to U.S. Government technology export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

## About Fuse

## Company Overview
- **One-liner**: Fuse is a fusion energy and defense company developing magnetized-liner inertial fusion (MagLIF) technology to deliver clean, on-demand power while providing radiation testing services for national security customers.
- **Entity Type**: Private (Series A)
- **Headquarters**: San Leandro, California, United States (operates "Fuseville" facility)
- **Founded**: 2018 (per CB Insights) or 2019 (per Wikipedia); founder J.C. Btaiche started the company at age 19
- **Founders**: J.C. Btaiche

## Core Business
- **Primary industry/industries**: Fusion energy, defense, nuclear effects testing, pulsed power engineering
- **Target customers**: U.S. government (Air Force, NNSA, national labs), defense contractors, eventually commercial energy utilities
- **Mission or purpose statement**: "Accelerating the World’s Transition to Fusion Energy" — building the fastest practical path to abundant, clean, safe, on-demand energy

## Products & Services
- **TITAN**: A 1 TW Impedance-Matched Marx Generator (IMG) — the essential MagLIF pulser building block. World’s first high-energy, high-power IMG, demonstrated in 2024 with results published in *Nature Scientific Reports*.
- **Z-Star**: A 15 TW MagLIF generator designed to iterate on and solve system engineering challenges (targeting 2027).
- **Apeiron I**: A pilot fusion plant design aiming to demonstrate a MagLIF hybrid plant core (targeting 203x).
- **FAETON I**: Neutron-producing fusion generator (over 1 trillion neutrons generated).
- **Radiation Testing Services (HEART)**: Hardened Electronics And Radiation Testing — providing short-burst radiation testing for government and commercial hardware resilience.

## Market Standing
- **Valuation**: Over $200 million as of September 2024 (per Bloomberg News)
- **Total Funding**: $32 million raised (Series A)
- **Key Metric**: 100+ employees; 2 patents filed; 53 employees as of 2024 (Wikipedia)
- **Notable Investors/Partners**: Bracket Capital, Tamarack Global, Buckley Ventures. Government partners: U.S. Air Force, National Nuclear Security Administration, Sandia National Laboratories, Los Alamos National Laboratory.
- **Growth Signals**: Awarded USAF contract (Feb 2024); published in *Nature Scientific Reports* (July 2024); former NNSA Administrator Lisa Gordon-Hagerty joined board; building Z-Star and Apeiron I platforms; operating a radiation facility covered by *Wired*.

## Competitive Advantages
- **MagLIF approach**: Integrates proven fusion technologies (magnetic and inertial) — demonstrated feasible by Sandia National Lab (2018, 2022). Fuse’s focus on engineering efficiency and affordability aims to solve repetition rate and cost barriers.
- **Rapid iteration**: Delivered two neutron-producing fusion generators and the world’s first IMG pulser in under three years, on time and on a lean budget.

- **Talent**: Aggressively hiring for plasma physics, electrical engineering, pulse power, mechanical engineering, and experimental physics roles.

## Why Work Here
- **Culture**: Described as "misfits, tinkerers, skeptics, doers" — drawn to impossible problems. Values include frugality, speed, hands-on experimentation, and deep technical conviction. "Fuse is not a comfortable environment" — no bean bag chairs; many live, eat, and work at the facility.
- **Work environment**: "Fuseville" — a shipping-container communal living facility adjacent to the lab. Bed-to-reactor commute under 60 seconds. Sleep pods available. You'll likely build your own desk. "We really skimp on furniture."
- **Compensation**: Low salaries — "you should be willing to work for free. While you will receive a minimum base so that you can survive, money and lifestyle is not the motivator." Significant stock option upside if fusion succeeds. "Fair wages. Long hours. High voltage. Success far from guaranteed."
- **Benefits**: Competitive healthcare plan. High-end computer setup and cloud computing resources. "Everyone on the team has skin in the game."
- **Who should apply**: Self-motivated, deeply internally driven, humble yet brilliant, fusion geeks who built Polywells in high school, boundary-pushers who "get shit done." Must be comfortable with deferred gratification and high risk.
- **Remote/hybrid policy**: Not explicitly stated, but the "Fuseville" on-site living model suggests heavy in-person presence is expected. "Commuting makes your blood boil" is a stated value.
- **Notable perks**: Working on one of humanity’s hardest problems alongside top 1% talent; national security impact; potential enormous financial reward via stock options; "glory in case of ignition."
