BlazeSQL - AI-native B2B SaaS platform for business intelligence.

OtherRemoteTeam 11-50

This is a job that Jill, our AI Recruiter, is recruiting for on behalf of one of our customers. She will pick the best candidates from Jack's network The next step is to speak to Jack. Job Title: Founding Engineer Salary: $150K-$220K + 0.5-1% Equity Company Description: Catalon - SF-based AI startup backed by Entrepreneur First Job Description: 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. Location: San Francisco, USA (Remote Open) 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. 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. The ideal candidate: - 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. Who are Jack & Jill? Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career.

Next steps Step 1. Visit our website. Step 2. Click 'Talk to Jack'. Step 3. Talk to Jack so he can understand your experience and ambitions. Step 4. Jack will make sure Jill (the AI agent working for the company) considers you for this role. Step 5. If Jill thinks you're a great fit and her client wants to meet you, they will make the introduction. Step 6. If not, Jack will find you excellent alternatives. All for free. We never post fake jobs This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network. Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description. We appreciate this can make them look a bit suspect, but there isn't much we can do about it. Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
