About Redwood Materials
Redwood is localizing a global battery supply chain that seamlessly integrates recovery reuse and recyclingkeeping critical minerals in circulation and driving the energy transition. Founded in 2017were 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.
Software Validation Engineer Energy Storage
The Redwood Vision: Architecting the Future of the Grid
We are at the precipice of a global energy transition. At Redwood Materials we are moving beyond battery recycling to build the most advanced circular energy ecosystem on the planet. Our goal is to shift the industry from static hardware-heavy infrastructure toward agile software-defined energy assets. The Software Validation team ensures that these complex systems are safe resilient and ready for grid-scale deployment.
As a Software Validation Engineer you are the bridge between pure code and physical reality. You will design andmaintainthe environmentsSoftware-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL)thatallowus to stress-test our power electronics and site controllers. Your mission is to build the automated frameworks that catch edge cases before they hit the field ensuring every product we ship meets the highest standards of reliability.
Key Responsibilities
- Validation Environment Design:Architect and scale ourSIL and HIL environments (using platforms like Typhoon HIL Opal-RT or similar) to provide high-fidelity simulations of battery assets and grid conditions
- Test Automation Frameworks:Lead the development of automated test suites inPython. You will transition our validation processes from manual intervention to a fully automated scalable framework
- V&V Strategy:Define and execute comprehensiveVerification and Validation (V&V) plans ensuring all software requirements for the site controller and embedded power electronics are met under normal and fault conditions
- CI/CD Integration:Integrate automated HIL/SIL testing into ourCI/CD pipelines providing real-time feedback to the development teams and serving as the final gate for production-ready code
- Hardware-in-the-Loop Interfacing: Design custom interface hardware and wiring for HIL benches bridging physical I/O from our controllers to simulated power stages
- Root Cause Analysis: Work closely with the firmware and systems teams to debug complex failures found during validation using logic analyzers oscilloscopes and telemetry logs to pinpoint issues
Qualifications
- Background: A BS or MS in Electrical Engineering Computer Engineering or a related field combined with 2 years of professional experience in software validation or test automation for hardware-focused systems
- HIL/SIL Mastery:Proven experience with real-time simulation platforms (Typhoon HIL Opal-RT ordSPACE) and a deep understanding of how to model power electronics components in a virtual environment
- Automation Toolchain:ExpertproficiencyinPython(specifically for test automation frameworks likePytest) and familiarity withRustandC/C to navigate embedded codebases
- Hardware Literacy:Comfortable in a high-voltage lab environment. You should be proficient with standard lab equipment (oscilloscopes power supplies electronic loads) and digital protocols likeCAN SPI and Ethernet
- Systematic Thinking: A dedicated mindset for breaking software. You havea track recordof finding critical edge cases in complex state machines and control loops
- Infrastructure:Experience withGitJenkins/GitHub Actions and containerization tools likeDocker for managing consistent test environments
