Engineering

We’re looking for a Software Engineer to join the founding team to own the core agent and data systems development. This is an intense role that will be fun for the right person. You will have a lot of autonomy and be surrounded by extremely talented engineers.

Who You Are

You’re a software engineer who has a strong grasp on building systems and handling large amounts of data, with a desire to get hands-on with advanced AI/ML work.

What You’ll Build

  • Design and implement the core agent architecture (state, tools, workflows, evaluations)

  • Build indexing, search, and retrieval systems to power agent reasoning

  • Design and maintain data ingestion pipelines that turn messy inputs into structured, usable context

  • Integrate LLMs, embeddings, and retrieval infrastructure into production systems

  • Build guardrails, evals, and observability to ensure reliability, performance, and cost control

  • Work closely with founders and product to translate real user needs into shipped functionality

You likely have:

  • 3+ years of experience as a backend, platform, or infrastructure engineer

  • Strong fundamentals in data structures, APIs, async systems, and distributed services

  • Experience building production data pipelines, ETL systems, or search/retrieval infrastructure

  • Strong capability working with Python and TypeScript in production

Ideal to have:

  • Experience with embeddings, vector databases, or hybrid search

  • Background in developer tools, infra, or technical products

  • Experience handling unstructured or domain-specific data

  • Undergraduate degree or minor in Mathematics
