Mechanical Engineer I
About The Position
Aalo Atomics is seeking a Mechanical Engineer I to support the design, build, testing, and fabrication of reactor systems and supporting infrastructure. This role is a chance to own complex mechanical hardware through the full lifecycle — concept and requirements, detailed design, fabrication, assembly, testing, and commissioning. You will work closely with controls, manufacturing and operations to manage system interfaces and outcomes. The work is hands-on: expect to split your time between CAD, the shop floor, and the test lab. The ideal candidate has solid mechanical design fundamentals paired with a demonstrated track record of real world electro-mechanical builds.
Requirements
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
- 1–3 years of hands-on engineering experience (industry, internship, co-op, or strong project equivalent).
- Demonstrated experience designing and building physical hardware.
- Proficiency with 3D CAD platforms such as SolidWorks, NX, Creo, or similar.
- Working understanding of GD&T, tolerance stack-ups, and engineering drawing practice.
- Experience with mechanical fabrication, assembly, or electro-mechanical testing.
- Comfortable wiring up instrumentation and reading basic schematics.
- Strong mechanical intuition and a willingness to learn by doing.
- Comfortable working with ambiguity and a high degree of ownership.
- Strong written and verbal communication skills.
- Based in the United States
- Willing to work on-site in Austin, TX
- Applicants must be U.S. Citizens or U.S. Persons in compliance with 10 CFR Part 810 and may not hold non-compliant foreign citizenships.
Nice To Haves
- Experience integrating actuators, motors, gearboxes, encoders, or position sensors into working mechanisms.
- Built custom test rigs, machines, or experimental setups in school, prior jobs, or personal projects.
- Experience with mechanisms: linkages, latches, drives, robotic or remotely operated equipment.
- Experience with fluid, gas, or vacuum systems (valves, seals, plumbing, hydraulics).
- Familiarity with data acquisition systems and basic controls or PLC interfaces.
- Hands-on project experience (e.g., Formula SAE, robotics, rocketry, hardware startups, machine shop work).
- Welding, machining, or fabrication skills.
Responsibilities
- Design mechanical components, mechanisms, and assemblies supporting advanced reactor technology, working under the direction of senior engineers.
- Develop 3D CAD models, engineering drawings, bills of materials, and interface documentation.
- Integrate actuators, drives, encoders, limit switches, and sensors into mechanical designs, and work with controls engineers on motion, interlock, and instrumentation requirements.
- Perform hand calculations and supporting structural, thermal, and mechanism analyses to size and justify designs.
- Build, instrument, and operate test rigs used to validate mechanisms, seals, and fluid system components.
- Work with machinists, welders, technicians, and vendors to get parts built and to keep designs practical and manufacturable.
- Develop tooling, fixtures, work instructions, and inspection plans for prototype and production hardware.
- Write and maintain test procedures, calculation notes, and design documentation.
- Travel occasionally to test sites, vendors, or the reactor installation.
Benefits
- Competitive salary based on technical level
- Health, Dental, Vision Insurance
- Paid Time Off
- Corporate Gym Membership
