About the role

Key responsibilities & impact

Build and ship features across the accounting product - from member-facing reconciliation and bookkeeping experiences to internal tooling that powers our accounting and bookkeeping operators.
Work on the integration layer between Collective and our partners that includes extending APIs, handling edge cases, and improving data reliability.
Improve the transaction pipeline that flows from bank feeds through our accounting platform into our data layer, including reliability, observability, and drift detection between source and destination.
Own well-scoped features end-to-end with support from senior engineers to define the approach, build, deploy, instrument, and iterate.
Partner with Product, Design, and Operations to translate accounting workflows into clean software, and surface engineering tradeoffs early.
Use AI-powered development tools (copilots, code agents, agent workflows) day-to-day to move faster and cut manual overhead.
Clear communication and collaboration skills across technical and non-technical partners.
Demonstrated ability to integrate AI agents and automation into development workflows and product features.

Requirements

What you’ll need

3–4 years of experience building and shipping production software in a product-focused environment.
Solid fullstack engineering skills (e.g., Python, Django, React, or similar modern frameworks).
Experience integrating with third-party APIs and working with messy, real-world data.
Hands-on use of AI developer tools (copilots, code agents) in your day-to-day workflow — not just experiments.
Ability to take a well-scoped problem and drive it to a shipped, instrumented solution with light guidance.
Good product and UX instincts to make sensible scope tradeoffs and ask the right clarifying questions before building.
Clear written and verbal communication, especially when explaining tradeoffs to non-engineering partners.
Familiarity with SQL and working with data warehouses (BigQuery a plus).
Interest in the accounting / fintech / payroll domain, or a track record of getting up to speed quickly in a new domain.
