Description

  • Own core product workflows for tax preparation, tax review, bookkeeping, client requests, and practice-management operations.
  • Design and build product abstractions that turn messy accounting work into repeatable, reviewable systems.
  • Use the internal agent platform to move quickly from product context to working software and validate the output.
  • Build interfaces, workflow states, data models, and agent behavior that perform reliably in live customer usage.
  • Codify repeatable patterns from customer deployments back into the main product.
  • Use the product directly, inspect logs and data, and troubleshoot issues until workflows are correct.
  • Learn how CPA firms move work from source documents to reviewed tax packages, books, and client follow-ups.
  • Shadow client workflows to identify opportunities to remove manual work.
  • Turn selected workflows into concrete product plans with inputs, states, edge cases, success criteria, and verification steps.
  • Drive AI-agent implementation loops from product plan to shipped feature.

Requirements

  • Strong programming skills and experience shipping production applications, serious internal tools, or customer-facing automation.
  • High agency and comfort working through ambiguity in messy customer environments.
  • Ownership mentality and willingness to do whatever it takes to make something work.
  • Good communication skills to explain technical tradeoffs and earn trust with non-technical stakeholders.
  • Comfort using AI coding agents as the primary implementation tool and holding their output to a high bar.
  • Experience with AI agents, React, Swift, TypeScript, Docker, and PostgreSQL.
  • Experience in accounting, finance, tax, audit, professional services, or another workflow-heavy enterprise vertical (preferred).
  • Previous founder experience or meaningful ownership at an early-stage startup (preferred).

Benefits

  • Base salary of $150,000–$225,000.
  • Equity of 0.25%–1.00%.
  • Opportunity to own major product surfaces end-to-end at a small team with high impact.
  • Lightweight, practical interview process tied directly to real work.
  • Work on a product already deployed with accounting firms across the country.
