Staff Field Engineer, Energy Storage Operations

Redwood is localizing a global battery supply chain that seamlessly integrates recovery, reuse, and recycling — keeping critical minerals in circulation and driving the energy transition. Founded in 2017, we’re delivering low-cost and large-scale energy storage and producing battery materials in the U.S. for the first time, all from batteries we already have.

Redwood Materials is seeking a highly experienced Staff Field Engineer, Battery Energy Storage Systems (BESS) to serve as a senior technical authority for the deployment, commissioning, operation, performance optimization, and lifecycle support of utility-scale and commercial battery energy storage systems.

This position is responsible for solving the organization’s most complex field engineering challenges across medium/high-voltage electrical systems, power conversion systems (PCS), battery modules, battery management systems (BMS), controls, communications, and SCADA interfaces.

The Staff Field Engineer will operate with a high degree of autonomy and serve as a senior technical escalation point for complex, high-impact issues that cannot be resolved through standard service procedures or conventional troubleshooting methods. The role requires substantial independent engineering judgment and is expected to resolve problems for which established procedures, documentation, or technical precedent may not exist.

The position will lead system-level troubleshooting, failure investigations, root-cause analysis, performance recovery, and technical resolution of critical equipment and system failures. Decisions and recommendations made by this role may directly affect personnel safety, system availability, customer operations, project schedules, lifecycle cost, and the reliability of Redwood’s deployed energy-storage portfolio.

Beyond individual site support, the Staff Field Engineer will translate field experience into scalable improvements across Engineering, Product, Quality, Operations, and Service, helping improve product reliability, serviceability, commissioning effectiveness, and long-term fleet performance.

Extensive travel, up to 75%, is expected to support critical deployments, commissioning activities, complex technical investigations, and escalations across Redwood’s operating footprint.

Essential Duties and Responsibilities

• Advanced Field Engineering & Technical Authority

• Serve as a senior technical authority and highest-tier field escalation resource for complex BESS commissioning, operational, performance, and reliability issues.

• Independently lead advanced system-level troubleshooting across high-voltage electrical systems, PCS/inverters, battery modules, BMS, controls, communications networks, SCADA interfaces, and balance-of-system equipment.

• Diagnose complex and intermittent failures involving interactions between electrical, mechanical, controls, firmware/software, communications, and thermal systems.

• Exercise independent engineering judgment to develop technically sound solutions when established troubleshooting procedures, documentation, or precedents are insufficient. Lead system commissioning, energization support, functional validation, performance testing, and operational-readiness activities for new and existing BESS
