Waiting for you on our team!

We're building a compliance platform from scratch: a fast client portal, an AI classification pipeline with human review gates, and integrations that move real money. You'll own the build end to end, with Claude Code as a primary tool and a senior reviewer behind you. The rule is simple: nothing merges that you can't explain.

This is a role for someone early in their career who wants to grow fast on a greenfield system with no legacy and a lot of responsibility.
