Engineer IV, Mechanical

locations: Rockville, MD
time type: Full time
job requisition id:R100176

Job Profile Tasks/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.

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

Provide feedback and guidance to more junior team members with the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document.

Led small groups of engineers to solve complex technical problems and deliver high-quality engineering work products on time and within budget.

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

Thermosystems

Support the development of reactor and plant control philosophy and implement it in plant models, simulations, and digital twins.

Support the sizing and analysis of components including heat exchangers, pumps, circulators, and turbomachinery.

Perform system-level thermodynamic analyses and process design using system-level simulation codes to support design iterations of X-energy-developed reactors and supporting subsystems.

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 downselect 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 by applicable procedures.

Develop Verification and Validation (V&V) plans for analytical tools and support qualification of the 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 deliver

ables and data.

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

Perform other duties as assigned by the manager.
