Role Overview Simfluent's platform automates the full recruitment lifecycle across five AI agents, a 22-stage candidate pipeline, and integrations with Lever ATS, SendGrid, and multiple job boards. As a Software Developer on the Platform team, you will build and own features across the backend API, async worker infrastructure, and third-party integrations that keep the platform running for enterprise tenants. Four years of experience means you have shipped real features in production, you understand why tests matter, and you can design a data model before you open your code editor. You work independently on well-scoped problems, raise quality concerns early, and know when to ask for help before a decision becomes expensive to reverse. This is a backend-first role with a strong Python focus.
