Grid Stor is looking for an experienced Director of Preconstruction to join our growing team. This role will report to the Senior Vice President of EPC and is responsible for EPC functions from project origination to NTP for our utility‑scale Battery Energy Storage System (BESS) portfolio across the United States. The Director of Preconstruction will serve as the primary technical and commercial strategist during early, mid, and advanced stages of projects (prior to construction stage), working hand‑in‑hand with the Development and M&A teams to de‑risk assets, validate costs, and ensure projects are “shovel‑ready” for the construction team.

• Development & M&A Support: Provide due diligence and cost‑modeling for early‑stage development projects and potential M&A acquisitions. Assess site feasibility and technology selection to support investment committee decisions. Where needed, provide initial due diligence and cost‑modeling for M&A projects that are in‑construction or operational stage.
• Early‑Stage Engineering: Manage internal and external engineering resources to produce 10–30% design packages. Oversee site layouts, single‑line diagrams, and technical specifications for utility‑scale BESS facilities.
• Budget & Estimating: Manage and prepare capex and opex (total cost of ownership) models related to EPC and operations scope. You will be responsible for industry best practices for estimates, ensuring cost certainty as projects move toward final investment decision.
• Scheduling: Work with development and M&A project managers to create and manage integrated project schedules; accounting for major equipment lead times, engineering timelines, construction timelines, market specific commissioning timelines, and construction permitting milestones; with understanding of interconnection timelines, financing milestones, and development milestones.
• EPC Procurement & Contracting: Lead the selection process for EPC contractors. Negotiate commercial terms, scopes of work, and exhibits for balance of plant and high voltage EPC contracts.
• Long‑lead procurement: Identify and manage the procurement of long‑lead equipment (e.g., battery, inverters, transformers, breakers) to support project COD dates while mitigating supply chain constraints.

Ensure a seamless transition from the preconstruction stages (early, mid, advanced), including M&A projects, to the Construction project team; providing all necessary documentation, risk registers, and budget clarity.

• Education: Bachelor’s or advanced degree in Engineering, Construction Management or related field.
• Experience: 8+ years of experience in construction management or preconstruction, with at least 5 years specifically focused on utility‑scale battery energy storage projects.
• Deep understanding of BESS technology and EPC constructability (high voltage substation and transmission lines, civil design, fire safety).
• Commercial Acumen: Proven track record in negotiating multi‑million‑dollar EPC contracts and managing complex procurement strategies.
• Location & Availability: Preference to be based in Portland, available to work a hybrid schedule.
