About The Position

About Mandrel 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. By grounding financial reporting in operational data, we give operators real-time clarity into inventory, costs, and cash flows. Founded in 2023, Mandrel has raised over $12M from top-tier investors including Lux Capital, Construct Capital, Zigg Capital, Asymmetric Capital Partners, WndrCo, and Clocktower Ventures. We are headquartered in New York and bring deep expertise in finance, AI, and scaled operations. About this role Mandrel’s Accounting Services business plays a unique and strategic role in our product roadmap: it is both a proving ground and a multiplier for our ERP platform. By operating real accounting workflows end-to-end for customers, this team pressure-tests new features, validates product assumptions, and uncovers the automation opportunities that inform how our ERP scales across our customer base. As a Forward Deployed Engineer , you will sit at the center of this feedback loop. You’ll work directly with Mandrel accountants and client stakeholders to understand their workflows, translate them into well-designed technical systems, and build integrations and AI-powered automations that eliminate manual work. The systems you build will not only power our accounting services operations, but also drive foundational workflows and components of Mandrel’s ERP platform. This role is ideal for an engineer who thrives in ambiguous, real-world environments, loves diving deep into business processes, and wants to help shape the technical backbone of how modern accounting for physical goods businesses should be run.
