They just need to come back. Today Redwood is the largest lithium-ion battery recycler in North America - recovering, refining, and redeploying critical minerals from end-of-life batteries back into the supply chain. On the energy side, Redwood has deployed the largest second-life battery project in the world, delivering power to AI data centers in months rather than years using proprietary energy architecture engineered entirely in-house. The company is profitable, the market it operates in is projected to grow 20 to 50 times over the next decade, and Redwood is the only company with the supply chain, the technology, and the operational scale to lead it.\nStaff Software Engineer\nRedwood Materials runs North America's largest battery recycling operation on Redwood OS, our internal software platform. Redwood OS owns warehouse management and manufacturing, the operations and maintenance that keep them running, and integrates with Microsoft Dynamics 365 as our ERP. It is the system of record for a $3B+ business, and we will be building on it for years. We are hiring a Staff Software Engineer to own a domain of that platform end to end: shaping what gets built with the business, designing it, shipping it, and running it in production. This is a permanent product area, not a project. Interview Process:\nPlease note that final-round interviews will take place in person at a designated office location. Travel details will be coordinated with selected candidates. \nResponsibilities:\nOwn a domain of Redwood OS end to end: shape the problem with the business, design it, ship it, and operate it in production.\nTurn ambiguous business asks into clear specifications that engineers and AI agents can execute without further interpretation.\nMake tradeoff-aware design decisions across service boundaries, data models, APIs, integrations, observability, and access control.\nSet the bar in code review: use AI effectively by decomposing work for agents, setting guardrails, verifying output at volume, and staying accountable for everything you ship.\nKeep the platform coherent as multiple engineers and agents change it in parallel.\nDebug and resolve production issues, and improve the reliability of the systems you own.\nRaise the output of everyone around you through documentation, conventions, tooling, and mentoring.\nWork directly with stakeholders on-site 3 days/week: floor walks, operator observation, pairing sessions, and demos.\nQualifications:\n10+ years of software engineering experience, including technical leadership of a significant system or domain.\nA track record of owning a problem space end to end with minimal direction.\nStrong Python and production React; experience building and operating applications on AWS.\nDepth in system design: API design, integration patterns, data modeling, and service boundaries.\nClear, concise technical writing - specifications, design documents, and pull requests that stand on their own.\nSophisticated use of AI coding agents, paired with full ownership of the result: you can explain every significant decision in the work you ship.\nJudgment to size effort to business value rather than to engineering interest.\nComfort working alongside warehouse and manufacturing operators on the floor, not only at a desk\nPreferred Qualifications: \nExperience as a tech lead or engineering manager, or otherwise accountable for the output of a team.\nDirect experience with ERP, WMS, MES, supply chain, or procurement systems.\nManufacturing, logistics, or recycling industry experience.\nIntegration experience with Microsoft Dynamics 365 Finance and Operations.\nExperience operating systems that a physical operation depends on around the clock.\nIn accordance with California pay transparency laws, the salary range for this position is listed below. Actual compensation may vary based on a variety of factors, including experience, education, and skills. \nCalifornia Pay Range:\n$217,500—$287,500 USD\nThe position is full-time. Compensation will be commensurate with experience.\nWe collect personal information (PI) from you in connection with your application for employment with Redwood Materials, including the following categories of PI: identifiers, personal records, professional or employment information, and inferences drawn from your PI.
