Deploy the next generation of energy infrastructure with Applied Atomics

Applied Atomics delivers firm, clean electricity with proven technology. We design, build, and operate nuclear plants directly alongside the facilities they power. With no reactor science or new fuel to invent , we have no reason to stall. We are the first fully integrated nuclear power provider built to deploy now. Founded by a team of engineers and operators who built the launch sites, test complexes, and factories behind SpaceX , designed and commercialized nuclear reactors, and ran billion-dollar asset portfolios , the team is now focused on clean power deployment.

Applied Atomics is b acked by Alpaca VC, Transition, and Morpheus Ventures.

About the role:

Applied Atomics is seeking a highly skilled CAD Designer with a strong background in 3D modeling and engineering design to support development across our entire product line, including the reactor system, balance-of-plant (BOP) systems, and overall plant / site layouts.

You will work closely with engineers from Nuclear Engineering, Balance of Plant, and Infrastructure / Site Development to create accurate 3D models, assemblies, drawings, and layouts that enable rapid iteration, manufacturability, and high-quality hardware execution.

This is a foundational role in our growing design organization. As one of the first designers on the team, you will help build our modeling standards, workflows, drafting methodologies, and PLM integration practices, while directly contributing to the physical layout and design of a first-of-a-kind (FOAK) nuclear power plant. If you excel in complex CAD environments, enjoy solving real engineering problems, and want to be part of a fast-paced, technically rigorous startup, this role is for you.

Why we need you

We are transitioning nuclear energy from a theoretical science into a practical reality, and that requires practical problem-solvers. We need engineers who are eager to take direct responsibility for their work and see it through to completion. Your role will be critical in transforming complex designs into safe, reliable, and operational power plants that will operate for decades to come.

What you will do

Key Responsibilities

• Create detailed 3D CAD models, assemblies, and fabrication ready drawings using Siemens NX (primary modeling software).
• Create relevant 3D CAD models of various equipment, structures, systems and/or components (e.g., Overall site layout, mechanical components and assemblies, piping and instrumentation, etc.).
• Generate accurate 2D manufacturing drawings, complete with GD&T (ASME Y14.5), and Bills of Materials (BOMs).
• Work closely with Responsible Engineers (RE’s) to translate concepts into manufacturable designs.
• Assist in defining mechanical interfaces between systems and components.
• Support design reviews, tolerance stack-ups, and fit‑check studies to validate form, fit, & function.
• Prepare and update drawings for manufacturing, assembly, installation, and construction.
• Maintain design data, revisions, and release processes within the PLM system (e.g., Teamcenter).
• Follow and help develop best practices for modeling standards, assembly structuring, drafting templates and annotation styles, and BOM generation.
• Help establish and reinforce internal modeling and drafting standards as the company grows.
• Support engineering across the Nuclear engineering (core support structures, shielding interfaces, & mechanisms), Balance-of-Plant engineering (piping, steam/water systems, pressure components, & HEXs), and Infrastructure & site development(plant layout, equipment rooms, routing, etc.) teams.
• Assist in multidisciplinary layout work including routing, equipment placement, access/maintenance envelopes, and…
