Senior Software Engineer

Fin Query stands at the forefront of accounting automation, driven by a deep specialty in contract-driven accounting. Our AI-enabled platform transforms how controllers and finance teams operate, seamlessly managing and accounting for the complex financial contracts—like leases, prepaids, and accruals—that are the backbone of modern business. We are not just a software provider; we are the unified subledger that eliminates time-intensive, error-prone technical accounting workflows, ensuring financial reports are accurate and empowering our customers to focus on strategic, high-value tasks.

Fin Query is the global leader in lease accounting (as recognized on ) and serve more than 8,500 customers worldwide. Our growth trajectory has been consistently validated by the Inc 5000, which has recognized us as one of the fastest-growing private companies for five consecutive years.

Fin Query is looking for a Senior Software Engineer to join our Engineering team. The Senior Software Engineer is an experienced technical contributor who combines deep engineering craft with a modern, agentic approach to software delivery. In this role, the engineer acts as both an orchestrator and a full‑stack builder—articulating problems clearly, directing AI agents across codebases, and guiding output to reliable, production-quality outcomes.

The position owns technical execution within the team, contributes to broader technical direction, and fosters a culture of pragmatic, high‑velocity engineering.
