Benefits offered by this job

Paid Time Off

Job summary

Aalo Atomics, based in Austin, TX, is advancing fast, practical testing of its microreactor platforms to accelerate learning and reduce risk. We seek a Senior Test Engineer to build, run, and evolve experimental systems that turn engineering questions into real-world data.

You’ll collaborate with mechanical, chemical, thermal-fluid, and nuclear engineers, manufacturing, and operations to design fixtures, collect data, and drive design decisions with credible results.

Qualifications

• You can reason clearly about physical systems and understand how to turn a technical question into a credible experiment.
• You are comfortable designing test setups involving mechanical hardware, thermal systems, fluid systems, pressure systems, and chemically relevant processes or environments.
• You understand how instrumentation, operating conditions, boundary conditions, failure modes, and measurement quality affect what a test result actually means.

Responsibilities

• Spend time with design engineers and technical teams to understand the real engineering questions behind prototype and test needs before building the hardware or procedure around them.
• Design, assemble, and iterate physical test setups ranging from simple benchtop experiments to more complex integrated mechanical and chemical development systems.
• Own test execution from first concept through fixture design, procurement, assembly, instrumentation, shakedown, debugging, operation, data capture, and post-test analysis.
• Build practical, reliable prototyping infrastructure that helps engineering teams learn quickly while maintaining appropriate safety, traceability, and technical rigor.
• Develop and run tests for mechanical, thermal, fluid, and chemical systems, including experiments that involve temperature, pressure, flow, materials compatibility, corrosion, contamination, cycling, or failure investigation.
