Lead the construction execution of America's first advanced nuclear fuel production facilities. This Senior Manager, Construction Projects role impacts the full lifecycle delivery of $100−500M capital construction programs — TRISO-X fuel fabrication facilities — where every field decision, subcontractor coordination, and safety protocol directly impacts X-energy's mission to deploy clean, reliable nuclear energy at scale.

You'll operate at both the strategic level (crafting project delivery approaches, evaluating construction techniques for best value, ensuring alignment across development teams and stakeholders) and the tactical level (mobilizing sites, managing daily field operations, driving subcontractor performance through work packages and earned value tracking, resolving construction issues in real time). This role demands seamless coordination across engineering, quality, construction, project controls, and physical security to deliver nuclear-grade facilities on schedule, on budget, and with the safety rigor that NRC-regulated and DOE environments require.

We need a proven construction leader who thrives in high‑complexity, highly‑regulated nuclear or government environments: someone who has successfully delivered $100M+ capital projects in nuclear, energy, or industrial settings under strict QA regimes (NQA-1, 10 CFR, DOE O 414.1D), commanded field teams and subcontractors through Design‑Build/Design‑Bid‑Build/Integrated Project Delivery models, and built the stakeholder trust required to present program status to owners, regulators, and executives under pressure.

You’ll manage project planning and schedules using Primavera P6, review construction estimates and specifications for constructability with engineering teams, participate in material review boards and NCR resolution, monitor costs and earned value to keep programs on track, ensure craft training and safety protocols are enforced daily, and lead change order evaluation and risk mitigation across civil/structural, electrical, and mechanical scopes. This role may work from active construction sites in all weather conditions with mandatory PPE — you’ll be leading from the field, not from a conference room.

• Manages and coordinates construction projects from conception to completion as assigned. The breadth and types of projects includes but is not limited to: nuclear operator and maintenance training facilities, mechanical/electrical/hydraulic testing facilities, major system integration facilities, and nuclear fuel handling/storage facilities and nuclear power plants.
• Supports development teams (constructors, technical authorities, owners, operators, other stakeholders) in crafting agreements to plan and execute projects.
• Provides oversight of in‑house and subcontracted work, including work planning and work package development, cost estimation, facility civil construction and systems installations.
• Reviews project construction estimates and schedules for understanding, clarity, appropriateness, and acceptability.
• Reviews specifications, drawings, work packages, and other “Issue for Construction” documentation with Engineering, Quality, Construction, etc., for constructability issues, optimization, clarity, and completeness.
• Evaluates construction techniques to achieve “best value”, such…
