Senior Software Engineer

About the role

LEDGE'S MISSION is to reinvent how finance teams work by building AI agents that actually do the work, not just automate it.

We began with an industry-leading reconciliation platform used by top finance teams. We are now broadening our scope to develop a completely AI-native close management solution, built upon our strong existing platform that is already competitive with leading industry offerings. Our agents autonomously prepare, reconcile, validate, and manage the close end-to-end with finance-grade accuracy and transparency. We’re designing new tools for the Office of the CFO: a scalable, trustworthy data pipeline combined with autonomous AI workflows and a clean, consumer-grade experience.

As an AI-first engineering organization, we use modern microservices, full IaC, and advanced AI coding and development tooling to move fast and build real autonomy into the finance workflow.

THE ROLE

We're looking for a strong Senior Software Engineer who thrives in fast-paced startup environments and takes full ownership of what they build.

This is primarily a backend role: Node.js/TypeScript experience is a must, and candidates should have at least 5 years of hands-on backend experience shipping production systems in cloud environments like AWS or GCP. Frontend experience (React + TypeScript) is a strong bonus. Candidates should be comfortable with modern architectures: microservices, event-driven workflows, distributed systems, and able to move quickly and independently.

Daily use of AI coding tools (Claude, Cursor, etc.) is a must, and exposure to AI-driven products or agents is a strong plus. We value engineers who are product-minded, pragmatic, collaborative, and excited to build AI-native systems end to end.
