Battery Software Integration Engineer

About the Role

At Redwood we are architecting the future of grid-scale energy storage and circular we rapidly scale our stationary Battery Energy Storage Systems (BESS) we are looking for a Battery Software Integration Engineer to build the bridge between diverse second-life automotive batteries and our modern scalable software platforms.

This role focuses on moving away from rigid hardware-centric infrastructure toward a resilient unified and software-defined energy storage architecture. You will be instrumental in making varied OEM packsoperateseamlessly off-vehicle turning proprietary automotive components into reliable building blocks for the will serve as the lead Software POC for external OEMs steering the critical technical discussions necessary to successfully adapt and integrate their battery systems into our architecture

Key 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 buildthe softwarehandshakes 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 managementutilizingmodern 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 controllercontrolsteams andour internalBMS 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.

Qualifications

• Technical Mastery:Proventrack recordin controls and software engineering with a deep practical understanding of lithium-ion battery architectures external BMS software and pack-level integration.

• Stakeholder Engagement & POC Experience:Demonstratedexperience acting as a primary software POC with external suppliers automotive OEMs or internal cross-functional teams. Mustpossessthe communication skills and technical authority to confidently lead complex software discussions drive alignment across organizational boundaries and steer reverse-engineering efforts.

• Modern Tech Stack:Proficiencyin modern software engineering practices and languages (Rust Python C/C).

• Protocols & Networking:Expertisein automotive and industrial communication networks (CAN LIN Automotive Ethernet) andtheir associateddiagnostic toolchains.

• Adaptive Problem Solving:Exceptional capability to reverse-engineer troubleshoot and adapt complex OEM electro-mechanical software systems for novel applications in circular energy ecosystems.

The position is full-time. Compensation will be commensurate with experience.
