Job Description X-energy is seeking a Senior Manufacturing Engineer responsible for translating complex nuclear component designs into manufacturable products for our small modular reactor program. This role requires expertise in heavy component manufacturing, with emphasis on design for manufacturability, process optimization, and quality assurance. The ideal candidate will work closely with vendors throughout the manufacturing lifecycle, from initial planning to final delivery, providing on-site monitoring and oversight during critical fabrication phases.

This position demands hands-on involvement in vendor management, fabrication surveillance, and manufacturing problem-solving to ensure our nuclear systems meet all technical specifications while being efficiently and safely manufactured.

Responsibilities Develop mechanical/physical concepts, design and support development of processes to create or identify structures, systems, and components (SSCs) for use in nuclear products or facilities with a focus on nuclear safety.

Identify, collect, and document applicable requirements, interfaces, design basis and criteria by coordinating with key stakeholders/systems engineers and support identifying applicable industry codes and standards and the direction of project leads and systems engineers.

Planning and performing the analysis required to assess aspects of the SSCs to ensure they can perform their intended functions and meet technical specifications and design requirements.

Perform computations utilizing hand calculations and analytical tools for structural, thermal, hydraulic, and other scoping calculations as required at the direction of project leads and systems engineers to ensure SSCs can meet technical requirements.

The role may include specialization in one or more of the following areas:

Mechanical Design Develop innovative mechanical solutions to refine and deploy concepts, technologies, and designs associated with X-energy developed reactors, including pressure vessels and piping, reactor internals, nuclear fuel, and high temperature materials such as graphite.

Integrate design activities across engineering team members, partners, and suppliers and perform supporting scoping and sizing calculations to down select design features to meet design requirements using guidance from consensus codes and standards.

Create and maintain CAD-generated engineering models of reactor SSCs.Support the assessment of SSCs for manufacturability as well as assembly and integration considerations at the direction of project leads.

Write and develop design documentation including design basis documents, technical reports, calculations, and drawings in accordance with applicable procedures.

Develop Verification and Validation (V&V) plans for analytical tools and support qualification of toolset.

Perform work in accordance with X-energy quality procedures for design and configuration management to ensure project quality requirements are met.

Provide independent reviews and acceptance reviews of engineering deliverables and data.

Lead the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document, without close supervision and extensive latitude for independent judgement.

Teach and mentor more junior team members.

Stay abreast of industry and academic trends, breakthroughs, and best practices.

Maintain professional demeanor and behavior at all times in all forms of communication.

Perform other duties as assigned by manager.
