This role is with one of Dex's trusted partner companies. The company is profitable, bootstrapped, and on a clear path to substantial growth, building an AI-native platform to disrupt a multi-billion dollar market. You’ll join a small, senior team building the core AI platform.
This is a true product engineering role: you own features end-to-end, from customer conversation to deployment and operation. You’ll translate ambiguous problems into shipped product, without intermediate handholding. This isn’t just writing code; it’s building and operating the LLM features that power the platform, sitting in customer calls, and taking full responsibility for what you ship.
The work:
- Own product features from initial customer problem to live deployment, translating ambiguity into tangible solutions.
- Design, build, and operate core LLM features: evals, agent loops, and retrieval over complex research data.
- Develop across the full stack – frontend, backend (Python), and AI components – to deliver integrated experiences.
- Engage directly with customers to understand pain points and inform product decisions.
- Take full operational responsibility for your code, including monitoring, alerting, and incident response.
What You Bring:
- Proven experience building and operating LLM-powered features in production, with a deep understanding of evals, RAG, and tool use.
- Strong full-stack engineering skills, capable of owning features from frontend to backend, with Python as your primary backend language.
- Experience designing and building complex backend systems, including schema design, async processing, and robust observability.
- A track record of shipping product in fast-paced, early-stage startup environments.
