Job description

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.

Mechanical Engineer, Fluids

As a fluids engineer at Forge, you'll be responsible for designing hardware to manage the complex network of fluids, piping, and plumbing required to operate a nuclear reactor. Fluids engineers at Forge will be responsible for designing tightly packaged fluid systems optimized for low cost, ease of manufacturability, and ultra-high reliability in a nuclear environment with challenging access. Successful candidates will have previously demonstrated extreme ownership in designing, testing and delivering complex and high reliability fluid systems.

Responsibilities

Design, build and deploy fluid systems to support rapid reactor build and test timelines

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 critical reactor test campaigns & operations, provide troubleshooting and technical support

Develop and maintain detailed timelines to capture and communicate project progress

Make high-value decisions on the fly, use feedback to continuously iterate and develop both product and process

Basic Qualifications

Bachelor's degree in mechanical engineering or a related technical discipline

1+ years of engineering experience designing, analyzing, and building mechanical hardware (internships and school project team experience qualify)

Preferred Skills and Experience

Strong interpersonal and collaborative skills, enthusiasm for problem solving, and desire to enable abundant clean energy

Experience leading or working on an engineering competition team, i.e. 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 working at a nimble engineering organization or in a highly technical position that required a scrappy, entrepreneurial manner to accomplish tasks with tight time or 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
