Founding Engineer at Catalon - AI engine for the $6T chemical industry

Catalon is hiring its first engineer to build the AI engine for the $6 trillion chemical industry. Founded by a Tesla alum and an Oxford physicist, this EF-backed startup is replacing manual email and Excel workflows with sophisticated agentic AI. If you are a 'cracked' engineer with 1-4 years of experience who loves shipping fast and owning the entire stack—from Pydantic AI to React—this is your chance to shape a company from the ground up. Enjoy a $150K-$220K salary, meaningful equity, and the chance to transform a massive global industry from San Francisco or anywhere in the world.

Overview

Role overview

As the first engineer at Catalon, you will build the AI-native infrastructure automating manual workflows for the $6 trillion chemical industry. Working directly with founders from Tesla and Oxford Physics, you will own the entire stack—from agentic orchestration to production deployment—transforming how global manufacturers handle complex operations in a high-trust, zero-bureaucracy environment.

Responsibilities

What you will do

  • Architect and build agentic AI systems using Pydantic AI, MCP servers, and tool-use orchestration to automate complex chemical industry workflows.
  • Design and implement end-to-end features across the full stack, including React/Next.js frontends, Postgres databases, and robust API integrations with ERPs like SAP and Oracle.
  • Shape the foundational engineering culture and technical roadmap while iterating directly with customers to turn ambiguous problems into shipped products.

Candidate profile

Who this is a fit for

  • Has 1-4 years of post-grad experience and a proven track record of shipping production-grade AI products or complex B2B SaaS systems end-to-end.
  • Demonstrates deep technical expertise in agentic orchestration (chain-of-thought, evals, RAG) and is comfortable managing the ambiguity of a pre-seed startup.
  • Possesses an "obsessed" problem-solving mindset, likely evidenced by building ambitious side projects just for fun and a desire to own the entire product lifecycle.

What makes it remarkable

Why this role is remarkable

  • Join as employee #1 at an Entrepreneur First S25 company already deployed with chemical companies, offering massive ownership and 0.5-1% equity.
  • Solve high-stakes problems in a massive, $6 trillion traditional market that still relies on manual processes, email, and legacy spreadsheets.
  • Work in a high-velocity environment with founders from top-tier backgrounds (Tesla, Berkeley, Oxford Physics) using a cutting-edge, AI-native technical stack.
