Software Engineering Lead, Warehouse & ERP Systems

We're replacing our legacy ERP and WMS with custom systems at North America's largest battery recycler. This role owns the product definition for a new warehouse management system - determining what gets built, why, and in what order through continuous stakeholder discovery across operations, finance, and logistics. You'll translate ambiguous business problems into clear, prioritized engineering work while keeping scope minimal and justified. The immediate focus is the 2026 cutover; after go-live, you'll help define what this product area becomes as the company scales. 

Responsibilities will include:

• Embed with warehouse operators, finance, and operations stakeholders, mostly on-site,  to define what the WMS must do at cutover. Make scope decisions that keep the system minimal; every requirement justifies its existence
• Own product outcomes for the WMS initiative. Success is measured by whether the system solves actual business problems, not by feature count or on-time delivery alone
• Map and manage a complex stakeholder landscape spanning most of the recycling organization. Build relationships, manage competing priorities, and keep stakeholders aligned as requirements evolve
• Run continuous product discovery in parallel with engineering execution — define goals and decompose them into incremental deliverables, validate assumptions, learn from what's been built, and adjust scope and priorities as you learn. Discovery doesn't stop when development starts
• Serve as the first line of defense against ambiguity for the engineering team. Absorb complexity so engineers can focus on building. Selectively involve engineers in stakeholder conversations to maintain their context and ownership
• Collaborate with the engineering manager and engineers on architecture decisions, feasibility trade-offs, and technical sequencing. You have technical credibility but your primary job is defining what to build, not writing code
• After cutover: drive stabilization, continuous improvement, and help define the next phase of the WMS product area

Qualifications:

• 8+ years of experience in software engineering and/or technical product leadership on engineering teams, including experience defining product scope, not just building to spec 
• Direct experience building, implementing, or heavily customizing warehouse management or supply chain systems - you understand how receiving, inventory, and shipping actually work 
• Track record translating ambiguous business problems into clear, prioritized engineering work on complex, multi-quarter initiatives 
• Strong cross-functional stakeholder management - able to interview floor operators, negotiate scope boundaries, and report status to leadership 
• Technical depth to evaluate trade-offs in Python, React, PostgreSQL, and AWS and communicate feasibility to both engineers and non-technical stakeholders 
• Willing to be on-site in Nevada at least 3 days a week 
• Clear and direct communicator comfortable operating in fast-moving environments where requirements evolve 

Preferred qualifications:

• Experience with ERP integration patterns (how WMS talks to financials) 
• Manufacturing, recycling, or logistics industry experience 
• Startup or high-growth company experience 
• Comfort with aggressive timelines and ambiguity
