Provides project controls support across risk management, scheduling, budgeting, estimating, and change management. Maintains project schedules, budgets, forecasts, risk registers, performance dashboards, metrics, and KPIs. Supports project leadership with progress tracking, cost reporting, financial analysis, risk mitigation, and status reporting. May perform quantity surveys using on-screen takeoff tools and works under guided supervision.

Develop and execute supply chain strategies for advanced nuclear fuel and reactor programs. Identify, qualify, and manage equipment and service suppliers; create category and project execution plans; analyze spend, risk, market conditions, costs, and schedules; negotiate supplier contracts and strategic agreements; review technical and quality requirements; coordinate supplier QA qualification; monitor supplier performance; manage delivery schedules; and provide commercial and contracting guidance across business units.

Provides project quality assurance for X-energy’s reactor development programs. Establishes and maintains quality management processes, analyzes nonconformances, implements corrective actions, supports inspections and supplier audits, delivers quality training, and reports program risks. Owns project quality plans and serves as the quality point of contact. Ensures compliance with nuclear, DOE, Canadian, international, and ISO requirements while promoting safety and quality culture. The role requires domestic and international travel to supplier and customer sites.

Designs and analyzes mechanical structures, systems, and components for terrestrial and space-based advanced nuclear reactors. Responsibilities include CAD modeling, structural hand calculations, FEA support, design for manufacturability, prototype testing, and cross-disciplinary coordination. The engineer maintains configuration-controlled models in Teamcenter, develops analysis plans, and supports integration of reactor components such as pressure vessels, heat exchangers, core structures, and transportation packages.

Implement supply chain processes and act as primary liaison with suppliers and stakeholders. Develop strategic and project-specific procurement plans, perform category spend and risk analysis, negotiate and manage contracts, ensure technical and QA requirements, monitor supplier performance, and support business development to meet schedule and cost objectives.

Design and develop mechanical systems and components for the Xe-100 reactor (reactor internals, steam generators, graphite core components), perform analyses and hand calculations, create CAD models and documentation, assess manufacturability, support testing/prototyping, and ensure compliance with codes and quality procedures.

The Mechanical Design Engineer will develop mechanical systems and components for nuclear reactors, performing analyses and supporting design, prototyping, and testing processes.

The role provides management support and technical leadership in mechanical engineering, overseeing teams in mechanical design, structural analysis, and thermal systems for advanced reactor plants.

Develops production-ready AI-native applications, agentic workflows, and cloud infrastructure supporting nuclear engineering. Responsibilities may focus on full-stack development, agentic AI, data and systems integration, or platform infrastructure and DevOps. The role involves LLMs, AWS services, engineering data platforms, digital-thread workflows, regulated software quality, system integrations, documentation, testing, and collaboration with systems engineering, licensing, and quality teams.

Leads systems engineering lifecycle activities for complex nuclear systems, including stakeholder and operational analysis, requirements management, architecture modeling, interface management, integration, verification, and validation. Develops system behavior models using MBSE and PLM tools, manages technical risks, supports value engineering, produces engineering documentation, and guides junior engineers. Collaborates across disciplines while following quality management and assurance procedures.
