The opportunity

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.

What you'll do

  • Distributed System Architecture: Design and implement a scalable, resilient software architecture for the Site Controller, ensuring it can coordinate thousands of distributed microcontrollers with zero downtime.

  • Tiered Control Logic: Lead the development of multi-rate control systems, balancing high-level site coordination with real-time grid execution. You will collaborate with simulation and controls teams to optimize state-of-charge and battery longevity at the site coordination layer, while leading the integration of high-speed closed-loop controls to ensure sub-cycle grid synchronization and precise command execution.

  • System Resilience & Fault Handling: Architect robust fault-management frameworks, designing the state machines responsible for autonomous error recovery and failsafe modes.

  • Deterministic Networking: Architect the physical and real-time networking layers. You will define the communication interfaces and network protocols that ensure low-latency, reliable data flow between the site controller, local assets, and upstream telemetry.

  • Hardware Abstraction & Integration: Design and define the critical software interfaces that enable our "Pack Manager" to serve as a universal translator. You will architect the communication layers to ensure high-availability and resilient data exchange between the centralized site controller and a heterogeneous fleet of downstream microcontrollers.

  • Testable Software Excellence: Design and implement highly modular, testable software. You are responsible for ensuring that all site controller logic is built with automated unit and integration testing in mind, providing a robust foundation for system-wide validation.

What they're looking for

  • System Diagnostics: Familiarity with distributed logging tools and optimizing telemetry data flows for real-time system health and performance tracking.
  • Background: A BS or MS in Computer Science or Electrical Engineering,: combined with 2+ years of professional experience developing application-layer software for hardware-constrained systems.
  • Modern Toolchain: Proficiency in Rust and Python. You understand when to leverage Rust’s safety and performance for site orchestration and how to utilize Python for rapid tooling and simulation.
  • Industrial Networking: Deep familiarity with industrial communication protocols (Modbus TCP and CAN). Experience with DNP3 or IEC 61850 is a significant plus.
