Design Engineer III

about the role

the design engineer iii is an experienced technical contributor responsible for independently executing complex c&i renewable energy designs, including solar, bess, hybrid/off‑grid systems, and lv/mv power distribution. This role serves as a project‑level technical lead, coordinating closely with project management, estimating, bim/cad, procurement, construction, and field teams. The design engineer iii performs advanced calculations, guides junior engineers, reviews deliverables for quality and constructability, and ensures designs meet contractual scope, code compliance, budget, and schedule requirements.

This role marks the transition from pure technical execution to emerging leadership and mentorship responsibilities.
