Jobbeschreibung

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

The role

Most engineers hate job searching. This company is fixing it. They're building an AI recruiter that cuts through the noise, connecting top software engineers with companies that truly fit. Backed by leading investors, they're scaling fast, solving a problem that impacts millions. This isn't a ticket-taker role. You'll own entire product slices, end-to-end, from spec to production. Think rich candidate databases, AI-powered matching dashboards, and workflows that transform recruiting operations. It's backend-heavy, full-stack, with LLMs in the critical path – not a side project. You ship, you own it, and it stays shipped.

The work

• Design and build core features for an AI-powered recruiting platform, from rich candidate search and filtering to operational dashboards.
• Integrate large language models directly into critical product paths, ensuring reliability and performance for AI-driven features.
• Develop robust backend services using Python, FastAPI, and Postgres, handling async patterns and ensuring production-grade stability.
• Ship pragmatic frontend components in React and TypeScript, unblocking yourself to deliver complete user experiences.
• Define and enforce API contracts, ensuring data integrity, idempotence, and clear error handling across the system.

What You Bring

• Proven track record owning and shipping end-to-end product features that scaled and stuck, with minimal supervision.
• Deep Python backend expertise: FastAPI or similar, async patterns, Postgres, Redis, with a default for production reliability.
• Experience building products where LLM integration is in the critical path, not an add-on, understanding production reliability challenges.
• Strong API discipline: you consider data integrity, error paths, idempotence, and versioning before shipping.
• Comfortable shipping workable frontend in React and TypeScript; you can build UI and review PRs to unblock delivery.
