Fluid Load Jobs (NOW HIRING)

About the Company

General Matter enriches uranium.

We are designing, building, and operating the world's lowest-cost enrichment services, here in the US.  

In the process, we are restoring America's ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. 

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume.  Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable.  We believe abundant nuclear energy will lead to a post-scarcity society. 

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.  

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production. 

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

About This Role

We are seeking a Fluid Systems Engineer to lead the design, analysis, and deployment of fluid systems for our uranium enrichment facility.

This role is responsible for developing highly reliable, manufacturable systems that move, store, and control fluids critical to enrichment operations. You will own systems from early sizing and architecture through detailed mechanical design, testing, and production ramp, working closely with manufacturing, operations, and safety teams.

Responsibilities

• Perform system-level sizing and performance analysis for fluid systems to establish requirements and operating margins.
• Translate requirements into hardware concepts, evaluating architectures and design trades for performance, safety, and manufacturability.
• Design pressurized and unpressurized components and assemblies, producing original CAD models, drawings, and specifications.
• Conduct structural and mechanical analysis to ensure survivability under pressure, thermal, and operational loads.
• Drive design-for-manufacturability improvements to enable efficient, repeatable production.
• Lead first-article builds and work directly with manufacturing teams to establish robust production processes.
• Plan and execute development, qualification, and acceptance testing for critical hardware.
• Define concepts of operations for systems, from commissioning and acceptance testing through steady-state operation.
• Participate in internal and external design reviews with cross-functional partners, suppliers, and stakeholders.

Basic Qualifications

• Bachelor's degree (or higher) in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Engineering Physics, or a related field.
• +4 years of experience in Fluids System design, analysis or hardware development

Preferred Skills and Experience

• Experience with gas dynamics, thermal analysis, and finite element analysis (FEA).
• Hands-on experience but not limited to pressurized systems (e.g., valves, regulators, piping, tubing, pressure vessels).
• Experience owning operation-critical hardware from concept through production.
• Proficiency with FEA tools and CAD software
• Comfortable working across disciplines with manufacturing, safety, and operations teams.
• Strong communication, organization, and technical leadership skills.

Additional Requirements

• Ability to work extended hours and weekends as necessary.
