Senior Software Engineer - Backend & Agent Platform

We're hiring a senior backend engineer to help build and strengthen the platform behind our AI agent — the systems that run agent work reliably and connect it to customers' accounting tools. This is a backend- and systems-leaning role for someone who cares about building dependable infrastructure for an AI-native product, and who's energized by reliability and correctness, not just shipping screens.

You'll join a small, high-ownership team where engineering sits close to the product. We work two-deep on every important system — no lone heroes, no undocumented black boxes — so you'll always have a partner, and we value people who document well and share what they know.
