Senior Software Engineer

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.

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.
