Role description
ProcIndexProcindex (Our new product) is building AI agents for accounting operations. We automate workflows across AP, AR, approvals, cash application, and ERP-connected finance processes.
We’re a small startup team, so this is a high-ownership backend role. You’ll work directly with the founders, ship fast, solve real customer problems, and help shape both product and engineering decisions. This is not a “ticket-only” job. We want someone who is comfortable with ambiguity, can move independently, and enjoys building from 0 to 1.
What working at a startup means here:\
- High ownership from day one\
- Fast shipping and quick iteration based on customer feedback\
- Solving messy real-world problems, not just building clean internal demos\
- Making pragmatic engineering decisions without overengineering\
- Working across product, backend, integrations, and production issues
What you’ll do:\
- Build and maintain backend services and APIs\
- Design systems for invoices, approvals, collections, matching, and reconciliation workflows\
- Build integrations with ERPs, email systems, and third-party tools\
- Work on AI agent workflows with proper guardrails, retries, logging, and fallbacks\
- Improve database design, reliability, observability, and background job processing\
- Debug production issues and help us move fast with early customers
What we’re looking for:\ - 3-6 years of backend engineering experience\
- Strong coding skills in TypeScript / Node.js\
- Good understanding of PostgreSQL, APIs, and backend system design\
- Experience with async workflows, queues, and third-party integrations\
- Comfortable working in a startup environment with speed and ambiguity\
- Strong ownership and ability to execute without heavy hand-holding
Nice to have:\
- Experience with AI agents / LLM products\
- Experience with fintech, accounting, ERP, or workflow automation products\
- Experience building multi-tenant SaaS systems\
- Experience working at early stage startup.
