Founding Engineer, Part-Time Partner (React Native, Supabase, Equity)

Part-time

FleetGen

ABOUT FLEETGEN

FleetGen is the compliance and carrier verification platform freight brokers use to stop fraud before a load moves. Since the Supreme Court's Montgomery v. Caribe ruling in May 2026, brokers can be sued for hiring the wrong carrier, and our data is how they protect themselves.

• Used by teams at Amazon, GEICO and the U.S. Department of Transportation

• 3,000+ users; peaked at over 2 million carrier searches in a single month earlier this year

• Users tell us they trust our carrier data over the incumbents' (Highway, Carrier411, RMIS)

• Launch has soft-committed to our current round and has expressed interest in our Series A

• Advised by a unicorn founder, and by an advisor with deep relationships in the current administration who also runs a quantitative hedge fund

WHAT'S ALREADY BUILT

The platform is in production with paying customers. You're joining to harden it and ship what's next, not to start from zero.

• Carrier search: our core product. DOT/MC and name lookup over FMCSA authority, insurance, inspection, crash and safety data, with a risk score and findings report per carrier.

• Carrier monitoring: watches carriers and alerts brokers when authority, insurance or ownership changes.

• AI COI verification: an agent that emails a carrier's insurer, follows the reply chain, requests the certificate of insurance and verifies coverage without a human chasing it.

• TMS + mobile driver app: shipments, customers, ELD tracking and audit-verified proof of delivery.

WHAT YOU'LL DO

• Own the bug queue: triage, reproduce, fix and ship, including performance issues on data-heavy pages

• Build new features end to end, from Postgres schema to React Native screen

• Harden security: Supabase Row Level Security policies, auth flows, secrets handling, API rate limiting and groundwork for SOC 2

• Improve the data layer behind search: schema design, indexing, query performance and ingestion pipelines for FMCSA and insurance data

• Extend our AI agents (COI verification today, more document and verification workflows next)

• Ship directly with the founders. No layers, no tickets passed through three people.

WHAT YOU BRING

• Strong JavaScript/TypeScript and React Native, with an app in production

• Real Supabase experience: Postgres, RLS, auth, edge functions, storage

• Solid data modeling: you design schemas, write migrations and read query plans

• Security-first habits: OWASP basics, least-privilege access, safe handling of PII and insurance documents

• You can take a vague problem, scope it and ship it without hand-holding

• Nice to have: LLM/agent workflows, email parsing, search tuning, logistics or insurance data

COMMITMENT

Part-time to start (about 15 to 20 hours a week), remote, as a partner rather than a contractor. Room to go full-time after the Series A.

COMPENSATION

• 5% equity in FleetGen

• 10% revenue share for your first 12 months

• $100,000 cash bonus when our Series A closes

• A founding seat: you shape the architecture and the engineering team that comes after you

HOW TO APPLY

Send your GitHub or a production app you built, one paragraph on the hardest bug you've fixed, and your weekly availability.
