External - Posting Description

Ideal Candidate:

The ideal candidate brings strong capabilities in project scoping, early ‑ phase field validation, and cost ‑ informing analysis, enabling them to contribute meaningfully to the development of well ‑ defined, executable project scopes across the NASP portfolio. They possess practical experience conducting early ‑ phase walkdowns, identifying constructability constraints, validating scope boundaries, and ensuring alignment between engineering intent and actual field conditions. Their background includes developing or supporting total project estimates, challenging scope or cost inputs where necessary, and integrating lessons learned from prior evolutions, skills essential to improving scope clarity and estimation accuracy. They understand how early planning decisions influence downstream execution and can translate incomplete or evolving information into structured, risk ‑ aware planning deliverables. A key strength of this candidate is their ability to coordinate effectively across Engineering, Projects, Operations, Maintenance, Supply Chain, and other stakeholder organizations. They build strong relationships, ensure the right technical voices are involved early, and facilitate alignment across groups that must collaborate to produce accurate scope, schedule, and cost inputs. They communicate clearly, seek clarification proactively, and help reconcile competing priorities in a way that protects plant safety, schedule integrity, and project readiness. In addition, the candidate is comfortable operating within TVA’s nuclear work processes and can contribute to the development of scoping packages, Engineering Change Packages, estimates, and implementation ‑ aligned requirements. Their combination of field awareness, analytical discipline, and cross ‑ functional coordination makes them a highly effective contributor to NASP’s mission of delivering predictable, well ‑ structured, well ‑ estimated projects ready for successful execution.
