Company Description

This early-stage company is reinventing the ERP stack for modern ecommerce businesses by building an AI-native operating system embedded directly into commerce platforms. Their product unifies inventory, operations, and financial workflows into a single system of record, replacing fragmented spreadsheets and disconnected tools. The platform is evolving toward agent-driven workflows that assist operators and accountants in real time, combining APIs, data infrastructure, and intelligent automation into one cohesive system.

What You Will Do

• Build and evolve core systems of record, including inventory ledgers, operational workflows, and financial subledgers


• Design and develop APIs and platform interfaces used by internal systems, partners, and agent workflows


• Embed AI-driven functionality into product workflows to improve operational efficiency and decision-making


• Work directly with customers to understand real-world workflows and translate them into scalable systems


• Prototype quickly and iterate toward production-grade systems


• Own product initiatives end-to-end across backend, data, APIs, and frontend surfaces


• Ensure systems are reliable, observable, and scalable under real-world operational demands


• Drive technical decisions and contribute to overall product direction

Ideal Background

• 6+ years of experience building and shipping production software


• Strong experience owning systems from early design through production


• Full-stack capabilities with strength across backend systems, APIs, and data modeling


• Strong proficiency in TypeScript (preferred)


• Experience working in fast-paced, high-ownership environments


• Strong product mindset — focused on delivering real user value, not just technical correctness


• Comfort working across ambiguous problem spaces and evolving requirements


• Ability to engage directly with customers and translate workflows into technical systems

Preferred

• Experience with APIs, platform design, or developer-facing systems


• Background in ERP, fintech, supply chain, or data-heavy operational systems


• Experience building transactional systems or ledger-based architectures


• Exposure to AI-assisted features, agent workflows, or MCP layers


• Familiarity with modern stack tools such as Next.js, NestJS, Prisma, GCP, Python, Terraform, or GraphQL


• Experience using AI tools (e.g., coding assistants) as part of development workflow

Compensation and Benefits

• Competitive base salary + meaningful equity


• Flexible PTO and strong healthcare benefits


• High-autonomy, builder-focused culture with direct impact on product direction


• Opportunity to work closely with customers and operators in real-time


• Hybrid / remote-first collaboration with optional in-person hubs (SF, NYC, Austin)


• Fast-moving team with strong emphasis on shipping, ownership, and real-world impact

This role is ideal for a product-minded engineer who wants to own systems end-to-end, work closely with customers, and build AI-native infrastructure that powers real business operations.
