About the role

Key responsibilities & impact

You'll build and own the platform that allows us to build reliable software on top of non-deterministic models, including agentic workflows, prompt iteration, tools, and evals.
You'll build flexible routing for AI-powered approval workflows that customers configure in natural language.
We're building an intelligent collections agent that you instruct in natural language, which then runs the entire workflow autonomously.
You'll have real influence on what we build and how we build it. Early enough to shape fundamental architecture. Late enough that customers depend on what you ship.

Requirements

What you’ll need

You've shipped LLM-based systems to real customers and have first-hand experience with how they fail in production
You've designed agentic systems and have informed views on the building blocks (like embeddings, memory, tool use, long-running state, recovery from partial failures) and when to reach for each
You’ve built evals infrastructure (like datasets, LLM as judge, prompt regression tests, monitoring) and have a clear view of what good looks like
You respect the weight of building business-critical systems on top of non-deterministic models and are comfortable writing resilient software
You have informed opinions about the tooling for building, evaluating, and securely running multi-provider AI systems in production
You've shipped production backend systems and care about the difference between "it works" and "it's reliable"
You care about customers - you want to understand why you're building something, not just what
You’re comfortable with ambiguity. You thrive in early ideation stages, share work-in-progress to gather feedback, and adapt easily based on input
You communicate clearly. Thoughtful communication is a superpower that sharpens how we collaborate and build
