About the Company

Humanity faces two critical challenges: securing reliable energy for everyone and aggressively lowering our environmental impact. Our client believes nuclear fission is the key to solving both at once. Today they are actively developing the technology to rapidly scale the deployment of nuclear fission.

The Opportunity

As a fluids engineer, 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 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. Sr. Fluids Engineers will own the most complex fluid systems while setting the technical bar for the fluids engineering team. 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
- Provide training and mentorship to junior fluids engineers, setting 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 interpersonal and coll
