Project Overview:

Our customer is a utility in central Arizona looking to add 2000MW of pumped energy storage to its storage capacity to meet growing demand on its network. We are building a high performing team to deliver this complex EPC heavy civil project and looking for motivated, hands-on, collaborative innovators, doers, and problem solvers. The project will involve the use of the existing Apache lake as the lower reservoir and creation of an upper reservoir by building dams in the Alchesay Canon, the reservoirs will be connected by underground waterways tunneled into the rock, channeling water down the ~1,200ft drop between the two reservoirs. The project scope includes significant access roads work development, construction of the upper reservoir with dams and an overflow spillway, underground tunnel waterways in challenging geological and hydrogeological conditions, upper and lower reservoir inlet/outlet structures, hydromechanical equipment, an underground powerhouse, and surface site facilities and buildings. This is your opportunity to be part of a truly historic project.

The position will be based in the Design Subcontractor offices in Denver, Colorado with regular visits to the BTJV Central Design Office in Mesa, Phoenix, Arizona.

Job Summary:

The Underground works engineering lead is the senior technical authority responsible for overall engineering leadership, integration, and assurance of all underground works for the SRP project. The role spans design development, discipline integration, technical governance, and construction support for underground scope.

The position requires extensive experience in underground works, strong leadership capability, and the exercise of advanced professional judgment to ensure that underground designs are safe, constructible, risk-managed, and compliant with SRP requirements and applicable codes and standards.

The Underground Engineering Lead provides single-point accountability for underground engineering across civil, structural, geotechnical, hydraulic, and construction interfaces, and leads engagement with the JV partner, design consultants, SRP, lenders' engineers, and other stakeholders.#LI-JL1
