Role
Who you are
- 5+ years software engineering experience
- Strong Python skills; production React experience
- Experience building and shipping production applications on AWS
- API design and integration patterns
- Comfort working independently in a remote-first environment and making pragmatic technical decisions
- Strong written communication - you document decisions and communicate async effectively

Desirable
- Direct experience with ERP systems, WMS, supply chain software, or procurement platforms
- Manufacturing, logistics, or recycling industry experience
- Event-driven architecture or workflow orchestration
- Enthusiasm for AI-assisted development
- Scrappy mindset - you've built under tight timelines and ambiguity
- Remote work experience on distributed engineering teams
What the job involves
- We're replacing our legacy Oracle ERP and WMS with custom systems at North America's largest battery recycler
- You'll be one of the engineers building warehouse management, procurement workflows, ERP integration, and operational applications that power a $3B+ manufacturing operation
- After go-live, you'll own and evolve these systems as the company scales. This is a permanent product area, not a project
- Own features end-to-end: design, build, test, deploy, and operate in production
- Write clean, tested Python and React code and participate in code reviews
- Design and build APIs and integrations between systems
- Work with domain experts and stakeholders to understand business processes and turn them into working software
- Contribute to technical design decisions
- Navigate a fast-moving environment where requirements change often and ambiguity is normal - prioritize effectively and adapt without waiting for perfect information
- Debug and resolve production issues; monitor and improve system reliability
- Collaborate remotely with team and stakeholders; periodic on-site travel (~1 week/quarter) for planning and stakeholder engagement
Our take
Redwood Materials, the brainchild of former Tesla co-founder and CTO JB Straubel, is making waves in the sustainable energy sector with its strategic approach to battery recycling and domestic supply chains for lithium-ion batteries.
The company is dedicated to creating a fully closed-loop supply chain by manufacturing critical battery components using as many recycled batteries as possible, effectively localising a 50,000-mile global battery supply chain on a single site. This strategy aims to address the critical issue of material sourcing, particularly the reliance on China for battery materials.
Redwood Materials closed a Series E funding round in 2025 at a post-money valuation exceeding $6B. This financial backing positions the company to continue expanding its capacity, further strengthening the US's domestic battery supply chain. Its ambitious goal of enabling customers to purchase battery materials made in the US is aligned directly with the broader political objective of onshoring critical industries, as emphasised in the USA's 2022 Inflation Reduction Act.
