Test Engineer

About the role

About Valar Atomics

At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable—unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.

The Team

As part of the Engineering organization, Mechanical Engineering designs and develops the mechanical systems, components, and equipment that power Valar's advanced nuclear technologies. The team ensures designs are robust, manufacturable, and optimized for long-term performance.

The Role

We are looking for a Test Engineer to design and build test stands, execute test campaigns, and turn raw test data into actionable insight. This role sits at the intersection of hardware, data, and compliance. You'll be hands on with test hardware and instrumentation while also owning the data pipeline that feeds our SCADA and historian systems. You'll work closely with engineering to troubleshoot issues, diagnose root causes from test data, and represent test results to government regulators.

Key Responsibilities

Test Stand Design and Execution

- Design, build, and maintain test stands for evaluating hardware performance, reliability, and compliance

- Develop test profiles and procedures tailored to specific test objectives such as performance validation, endurance, environmental, and failure analysis

- Run tests, monitor live data, and adjust test parameters as needed to capture meaningful results

Data Acquisition and Integration

- Set up and maintain data acquisition systems for tests, including remote and unattended data acquisition capability

- Integrate test stand data streams with existing SCADA and historian infrastructure

- Process and structure raw test data into clean, usable formats for engineering analysis and reporting

Troubleshooting and Diagnostics

- Troubleshoot issues arising during test execution, including instrumentation, test stand hardware, and data acquisition faults

- Analyze test data to diagnose root causes of issues in existing product designs

- Collaborate with design engineers to translate test findings into actionable design recommendations

Reporting and Compliance

- Prepare clear, accurate test reports and supporting documentation

- Maintain organized records of test procedures, configurations, and results for traceability

- Present and explain test results and methodology to government regulators and auditors as needed
