About The Company
Mandrel is building the AI-native ERP for physical goods. Today, our wedge is simple and painful: true, auditable gross margin by SKU and channel, tied to real supply-chain source of truth documents.

Advocate for customers internally by clearly articulating needs, risks, and tradeoffs to product and engineering teams
Confidently push back on unreasonable or out-of-scope requests while maintaining trust and alignment with customer stakeholders
Identify patterns across implementations and build the playbook for a repeatable, scalable implementation process as Mandrel grows
Partner closely with sales, solutions, product, and engineering to ensure smooth handoffs and tight feedback loops
