Nuclear Associate Mechanical Manager ENERCON United States, Arizona, Tonopah Sep 18, 2026

Overview ENERCON is seeking a Mechanical Associate Manager to join our growing team of nuclear professionals. In this role, you'll contribute to the evaluation and implementation of power uprates at nuclear facilities, helping to increase reactor output safely and efficiently, while also providing technical leadership, mentoring developing engineers, and supporting project execution. You'll work alongside experienced engineers, gaining exposure to a wide range of technical challenges and project scopes. This is an exceptional opportunity for engineers who aspire to grow into advanced technical and leadership roles. Power uprates span the entire plant and typically involve major upgrades such as replacing large pump motors, generators, high-pressure turbines, and feedwater heaters. As such, this role provides a comprehensive understanding of plant systems and their interdependencies. We invest in our people and provide opportunities to grow as a technical expert, project leader, or people leader. If you're ready to contribute to high-impact nuclear projects while helping shape the next generation of engineers, we encourage you to apply.

Why this role stands out:

Strategic Impact:

Power uprates are rapidly becoming a cornerstone of U.S. energy policy, driven by recently passed legislation aimed at accelerating clean energy deployment. This role places you at the center of that transformation. Power uprates are the quickest and most cost-effective way to bring more nuclear power on-line.

Career Springboard:

With the U.S. targeting a fourfold increase in nuclear capacity-from ~100 GW today to 400 GW by 2050-power uprates are anticipated to only contribute approximately 8 GW. To meet this ambitious goal, the industry will soon shift focus to designing and constructing new reactors, including advanced and small modular reactor technologies. This role positions you to transition seamlessly into those future projects, giving you a front-row seat to the next generation of nuclear development.

Mentorship & Growth:

Work alongside senior subject matter experts (SMEs) who will provide hands-on mentorship and help you develop into a future power uprate specialist.

Leadership Pathways:

This role is designed to groom engineers for leadership-whether you choose to specialize technically, lead teams, or guide future uprate studies and modifications.

Collaborative Culture:

Join a team that values innovation, knowledge-sharing, and continuous improvement. Responsibilities We invest in our people and provide opportunities to grow as a technical expert, project leader, or people leader.
