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.
Forge is seeking a mechanical engineer to design the fluid systems required to operate a nuclear reactor, including the piping, tubing, and associated hardware. Fluids engineers at Forge design tightly packaged systems optimized for low cost, manufacturability, and high reliability in a nuclear environment with limited access. Sr. Fluids Engineers will own the most complex fluid systems while setting the technical bar for the fluids engineering team. Successful candidates will have a demonstrated record of designing, testing, and delivering complex, high-reliability fluid systems.
Responsibilities
Design, build, and deploy fluid systems to support reactor build and test schedules
Perform detailed fluids analysis to characterize and troubleshoot expected design performance
Work closely with our in-house build shop to develop and own the scaling of the manufacturing line for your system
Support reactor test campaigns and operations with troubleshooting and technical support
Develop and maintain detailed timelines to capture and communicate project progress
Make timely, well-reasoned engineering decisions and use build and test feedback to improve both product and process
Mentor junior fluids engineers and set the standard for technical rigor across the team
Basic Qualifications
Bachelor's degree in mechanical engineering or a related technical discipline
5+ years of engineering experience designing, analyzing, and building mechanical hardware
Preferred Skills and Experience
Strong communication and collaboration skills across engineering disciplines
5+ years of experience designing and analyzing fluid systems via professional work experience, project/research-based student experience, or a combination of both
Experience acting as a technical lead: scoping work, reviewing designs and processes, and guiding other engineers to successful outcomes
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
Hands-on experience with fluid, gas, or thermal systems
Experience using test instrumentation and control components (e.g. pressure transducers, thermocouples, resistance temperature detectors, relays, solenoid valves, etc.)
Experience designing highly integrated and complex fluid systems in high reliability environments
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:
Senior: $140,000.00 - $210,000.00/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.
