Controls Engineer - Fuel Handling 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 the Controls Engineer integrated in the Fuel Handling System (FHS) team, you will own the controls, instrumentation, and automation for a remotely‑operated, encoder‑positioned machine that handles nuclear fuel assemblies in a sodium environment. The FHS will be operated entirely from outside the reactor building during normal operations, which means controls reliability is central to whether the system works at all. This is a hardware‑leaning controls role. You will spend significant time with a multimeter, crimping tool, and wire spool—building cabinets, wiring up sensors and actuators, integrating motion controllers, and standing up test benches—in addition to writing the code that runs them. We are looking for someone who is energized by getting hardware to actually move, not someone who wants to live in a software IDE. We are open to two candidate profiles: an experienced controls engineer who prefers hardware and is comfortable writing the automation scripts to support testing, or a senior technician with deep wiring and instrumentation experience who is hungry to grow into the engineering and coding side of the role. Either way, you will be a core member of a small, in‑person team in Austin and will work day‑to‑day with mechanical and test engineers. Responsibilities Build and wire control cabinets, junction boxes, and test bench panels from schematic through commissioning Select, install, and integrate instrumentation: encoders, load cells, pressure and temperature sensors, limit switches, gas composition sensors, cameras Integrate motors, actuators, solenoid valves, and pneumatic/hydraulic systems with controllers (PLC, motion controller, or embedded) Write the automation, sequencing, and data logging code needed to run component test benches and the full‑system prototype (Python, PLC ladder/structured text, or similar) Develop motion control strategies for the gantry/trolley/hoist system, including encoder‑based positioning over fuel plug locations Implement interlocks, fault detection, and safe‑state behaviors for sodium and inert gas operations Coordinate with other controls engineers on operator HMI, panel build support, and component sourcing Diagnose electrical and control system faults at the test bench; own the wrench‑and‑debugger side of integration Document wiring, cable schedules, control logic, and operating procedures clearly enough that any team member can follow them Support on‑site installation and commissioning at the reactor facility in Idaho with occasional travel Basic Qualifications 5+ years of hands‑on experience in controls, instrumentation, or electro‑mechanical systems, OR equivalent technician/tech‑lead experience with demonstrated growth into coding and engineering work Strong hands‑on skills with cable routing, panel layout, and electrical troubleshooting Experience integrating sensors and actuators with at least one of: PLCs, motion controllers, microcontrollers, or industrial PCs Ability to write simple automation and data acquisition scripts (Structured text, ladder logic, structured text, Python or similar) Comfortable reading and producing electrical schematics, P&IDs, and cable schedules Comfortable owning a system from blank cabinet to commissioned hardware Preferred Experience Motion control experience (servo drives, stepper drives, multi‑axis coordination, encoder feedback) Experience with safety interlocks, E­stop circuits, and fail‑safe control design Exposure to high‑temperature, sodium, vacuum, or inert gas systems Familiarity with industrial communication protocols (EtherCAT, Modbus, EtherNet/IP, CANopen) Background in nuclear, aerospace, semiconductor, or other high‑reliability industries Experience working in a flat, fast‑iterating team where the controls engineer is also the cabinet builder Physical Comfortable working on the factory floor and in test labs alongside technicians, welders, and machinists Ability to lift up to 25 lbs and stand for extended periods Physical dexterity for wiring, panel assembly, and hands‑on troubleshooting Requirements Must be based in the United States Must be willing to work on‑site at our headquarters in Austin, Texas What It Takes to Succeed at Aalo Extreme Ownership You take responsibility for outcomes, not just tasks. You proactively identify problems, drive solutions, and follow through. A Passion for Solving Hard Problems You are energized by challenges that others avoid and enjoy finding practical solutions to complex technical issues. A Sense of Urgency You move quickly, make thoughtful decisions, and maintain momentum while balancing quality and execution.
