the lottery is wage-weighted — each level is one more entry
$13,131 more — $165,131 — moves this role to Level II and 2 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $165,131 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Software Developers" for prevailing-wage purposes.

About the role
- At Redwood, we are architecting the future of grid-scale energy storage and circular energy ecosystems.
- This role focuses on moving away from rigid, hardware-centric infrastructure toward a resilient, unified, and software-defined energy storage architecture.
- Proven track record in controls and software engineering with a deep, practical understanding of lithium-ion battery architectures, external BMS software, and pack-level integration.
Responsibilities
- Technical OEM Partnerships: Be the lead engineering voice bridging the gap between legacy automotive hardware and modern software infrastructure.
- Dive into the technical weeds with tier-1 suppliers to decode firmware, negotiate engineering solutions, and build the software handshakes that make second-life integration a reality.
- Architectural Integration: Design and deploy translation layers and software gateways to seamlessly integrate vendor-off-the-shelf and second-life OEM battery packs into our centralized energy storage system.
- Modern Software Development: Develop robust, containerized applications to handle external BMS communication, data parsing, and fault management utilizing modern technologies like Rust and Python within Linux environments.
- System Resilience: Build highly resilient communication interfaces (CAN, Ethernet, Modbus) capable of dynamically handling the idiosyncrasies and proprietary logic of different OEM packs without compromising overall system stability.
- Cross-Functional Collaboration: Partner closely with power electronics, site controller, controls teams, and our internal BMS developers to ensure safe, optimized, and harmonized operation of integrated modules within the broader BESS architecture.
- Validation & Testing: Drive rigorous validation across simulation tools, Hardware-in-the-Loop (HIL) platforms, and physical battery hardware to verify OEM BMS behavior, safety boundaries, and control algorithms under novel off-vehicle duty cycles.
- Design and deploy translation layers and software gateways to seamlessly integrate vendor-off-the-shelf and second-life OEM battery packs into our centralized energy storage system.
- Build highly resilient communication interfaces (CAN, Ethernet, Modbus) capable of dynamically handling the idiosyncrasies and proprietary logic of different OEM packs without compromising overall system stability.
- Must possess the communication skills and technical authority to confidently lead complex software discussions, drive alignment across organizational boundaries, and steer reverse-engineering efforts.
Requirements
- Technical Mastery: Proven track record in controls and software engineering with a deep, practical understanding of lithium-ion battery architectures, external BMS software, and pack-level integration.
- Modern Tech Stack: Proficiency in modern software engineering practices and languages (Rust, Python, C/C++).
- Protocols & Networking: Expertise in automotive and industrial communication networks (CAN, LIN, Automotive Ethernet) and their associated diagnostic toolchains.
