Mechanical Engineering System

About Aalo Atomics Aalo Atomics is pioneering a new era in clean energy with factory-fabricated microreactors designed to deliver affordable, scalable, and reliable nuclear power. Our mission is to make nuclear energy globally accessible, starting with the Aalo-1, a 10 MWe reactor leveraging cutting‑edge safety, modularity, and efficiency. Based in Austin, TX, we’re rapidly growing as we work to deploy the world’s first fleet of advanced microreactors. Join us and help revolutionize energy for a sustainable future.

About the role As a Test Engineer on the Fuel Handling System (FHS) team, you will help build and operate the test infrastructure used to validate complex mechanical systems operating in challenging environments—mechanisms, sealing systems, sodium-compatible components, and fluid systems used in fuel handling, cleaning, and storage.

Working closely with senior test and design engineers, you will own day-to-day execution of component test campaigns: building rigs, instrumenting hardware, running cycle tests, capturing data, and chasing down failure modes. Responsibilities Build, instrument, and operate test rigs for mechanical, thermal, and fluid system validation

Execute test plans on components such as valves, seals, hoists, grapples, and handling mechanisms

Wire and configure sensors (pressure, temperature, force, position, gas composition) and data acquisition systems

Perform hands‑on fabrication, assembly, and modification of test hardware

Support sodium exposure testing, cleaning cask development, and mechanism qualification campaigns

Help write and refine test procedures, checklists, and as‑run logs

Support system integration, full‑scale prototype operation, and on‑site commissioning as needed

Travel occasionally to test sites or the reactor installation

Basic Qualifications Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or related field

1-3 years of hands‑on engineering experience (industry, internship, co‑op, or strong project equivalent)

Experience with mechanical fabrication, assembly, or electro‑mechanical testing

Strong mechanical intuition and willingness to learn by doing

Preferred Experience Experience with fluid systems (valves, seals, gas, vacuum, hydraulics)

Built custom test rigs or experimental setups in school, prior jobs, or personal projects

Familiarity with instrumentation and data acquisition systems

Hands‑on project experience (e.g., Formula SAE, robotics, rocketry, hardware startups, machine shop work)

Welding, machining, or fabrication skills

Willingness to perform hands‑on work including assembly, plumbing, wiring, and troubleshooting

Must be willing to work on‑site at our headquarters in Austin, Texas

A Sense of Urgency You move quickly, make thoughtful decisions, and maintain momentum while balancing quality and execution.
