Commissioning Manager at Scale Microgrid Solutions – Oakland, California

We are looking for a Commissioning Manager to oversee and manage the preparation and coordination of commissioning activities for a portfolio of microgrid projects utilizing solar PV, battery energy storage systems (BESS), generators, and associated switchgear and controls. You will own the commissioning planning, documentation, scheduling, and resource coordination across multiple active project sites.

This is a great role for someone looking to play an important technical role at a fast-growing PE-backed business.

You will report to our VP of Project Engineering and Preconstruction and will be a hybrid role based out of our Oakland, CA, Santa Monica, CA, Ridgewood, NJ, or NYC offices.

• Develop, manage, and maintain commissioning plans, schedules, and execution strategies across multiple microgrid projects simultaneously.
• Define commissioning scope, sequencing, resource requirements, readiness criteria, acceptance criteria, and handoff requirements for solar PV, BESS, generators, switchgear, protection, and controls.
• Establish and maintain standardized commissioning processes, templates, procedures, and documentation to be used across the project portfolio.
• Track commissioning progress, risks, and constraints across all active sites and communicate status to project leadership.
• Coordinate commissioning activities performed by EPCs, OEMs, integrators, utilities, and third-party independent commissioning agents.
• Manage interfaces between commissioning activities and construction completion, energization, and utility interconnection. Support temporary power planning, procurement, and implementation for on-site commissioning activities.
• Collaborate closely with Engineering, Project Management, EHS, Controls, and Operations teams to ensure commissioning readiness.
• Review and approve commissioning test plans, FAT/SAT procedures, and functional test scripts.
• Ensure integrated system testing validates microgrid functionality, including islanding, resynchronization, black-start, and load management.
• Coordinate with utilities, AHJs, and inspectors to support energization, witnessing, acceptance, and performance testing.
• Ensure proper turnover of commissioned systems to Asset Management, including training coordination and documentation completeness.
• Capture lessons learned and continuously improve commissioning processes across the portfolio.

• 10+ years of experience in commissioning management, power systems engineering, or project delivery for DER, microgrid, or utility-scale power systems.
• Demonstrated experience managing commissioning activities rather than solely performing field execution.
• Experience coordinating multiple stakeholders across parallel project sites.
• Experience managing third-party commissioning agents or EPC-led commissioning efforts.
• Familiarity with grid-forming and grid-following inverter-based resources.
• Strong program-level planning and organizational skills.
• Clear communicator capable of aligning internal teams, vendors, and utilities.
• Proactive problem solver with a systems-level mindset.
• Comfortable operating in a matrixed, fast-paced project environment.
• Understanding of onsite power generation, including parallel operation with the utility bus as well as with other DERs, both in grid parallel mode and island mode operations.
• Solid understanding of the utility side of the interconnection.
• Ability to interpret single-line diagrams, control narratives, protection schemes, and network architectures.
• Willingness to travel selectively to project sites for key commissioning milestones.
• A BS in Engineering is required; A BS in Electrical Engineering with a focus on the power side is preferred.
