Senior Software Engineer

Job description

**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.

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.
