Fullstack Software Engineer

About the role

We're hiring a Software Engineer to help build and scale the systems that power Collective's accounting product. This is a product engineering role with real ownership, working closely with Product, Design, Operations, and our in-house accounting team to ship fast and iterate based on member and operator feedback.

What You'll Do

• 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
• Demonstrate ability to integrate AI agents and automation into development workflows and product features

What You'll Bring

• 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
