Factory-built water-cooled nuclear reactors
Humanity faces two critical challenges: securing reliable energy and aggressively lowering our environmental impact. At Forge, we believe nuclear fission is the key to solving both at once. Today Forge is developing the technology to rapidly scale the deployment of nuclear fission.
The Nuclear Engineer role is responsible for end-to-end ownership of the nuclear design and safety analysis of Ember, our first reactor, spanning core design and fuel cycle, reactivity control, and radiation release and dose analysis. Nuclear Engineers will advance the design from today's working simulation models through design finalization, licensing, and first criticality, and will build the analysis tools and methods needed to do so on an accelerated schedule. Successful candidates will have a demonstrated record of modeling, analyzing, or de-risking complex physical systems.
Responsibilities
Support key aspects of nuclear core design including fuel assembly design, reactivity control through burnable poisons, chemical, and mechanical shim, thermal hydraulics, and fuel cycle design
Own reactivity control design and analysis: control rod worth, shutdown margin, reactivity coefficients, chemical and mechanical shim, and transient response
Perform radiation shielding and release analysis against regulatory limits
Work closely with fluids, structures, components and manufacturing teams to deliver a highly system-optimized and manufacturable design
Maintain tight partnerships with fuel procurement supply chain including enrichment service providers and fuel assembly fabricators to ensure high manufacturability of our design
Own a significant portion of the nuclear system through initial criticality, extended full power operations, and fleet wide commercial deployment
Basic Qualifications
Bachelor's degree in nuclear engineering, physics, or a related technical discipline
1+ years of engineering experience designing, analyzing, and building complex hardware (internships and school project team experience qualify)
Preferred Skills and Experience
Strong communication and collaboration skills across engineering disciplines
Experience leading or working on an engineering competition team such as Formula SAE, Baja SAE, Solar Car, Rocketry, Cubesat, or similar
Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information
Experience in a fast-paced hardware development environment with tight schedule and budget constraints
Experience with nuclear system design and analysis, including core geometry, reactivity simulations, depletion analysis, and radiation shielding
Experience with thermal hydraulics, heat transfer, and fluid flow regimes
Experience designing to key regulatory standards such as 10 CFR Part 50/52/53
Experience with radiation release analysis, including source term determination and dispersion analysis
Additional Requirements
Position will be based in the South Bay area of Los Angeles County and will require relocation if not already local. The position will be full-time in the office.
Ability to work extended hours and weekends as necessary
Ability to travel to reactor construction sites in other states as necessary
Compensation and Benefits
Pay range:
Level I: $115,000.00 - $130,000.00/per year
Level II: $125,000.00 - $150,000.00/per year
Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience.
Base salary is just one part of your total rewards package at Forge. You may also be eligible for long-term incentives, in the form of company stock or stock options, as well as potential discretionary bonuses and the ability to purchase additional stock at a discount through an Employee Stock Purchase Plan. You will also receive access to comprehensive medical, vision, and dental coverage, access to a 401(k) retirement plan, paid vacation, paid parental leave, and various other perks. Employees accrue paid sick leave pursuant to Company policy which satisfies or exceeds the accrual, carryover, and use requirements of the law.

Factory-built water-cooled nuclear reactors
Forge Atomics designs and builds factory-built, water-cooled nuclear fission reactors to provide reliable, carbon-free baseload power. Its core product is the Ember 25 MWe reactor, with a subscale Ember Mini prototype planned before moving to full-scale deployment. The reactors are manufactured in a factory setting, using proven water-cooled reactor technology with decades of operating experience, and then shipped as modules to site where they are installed, commissioned, and operated. The company aims to lower costs and speed deployment by using mature supply chains and a mass-production approach instead of on-site, bespoke construction. Its safety approach relies on passive safety features designed to make accidents physically unlikely. The ultimate goal is to offer safe, scalable nuclear power that complements or replaces intermittent renewables, improving energy security and reducing environmental impact.
