Jose has exceptional founding engineer credentials with proven 0→1 execution on complex, correctness-critical systems at scale (real-time voice platform, emergency response infrastructure, crypto wallet). His full-stack depth across backend (FastAPI, PostgreSQL, Redis), infrastructure (AWS, Kubernetes, Docker), and ability to own architecture decisions end-to-end aligns perfectly with the CTO role. However, he lacks direct exchange/trading systems experience and has not built matching engines or order books, which are core technical requirements for this role.

Hook: Your background shipping correctness-critical systems at scale—from 8M-user crypto wallets to real-time AI infrastructure—positions you perfectly to architect a peer-to-peer trading exchange from scratch.

Missing: Matching engine / order book design, Exchange or trading systems experience, Payment settlement systems, On-chain / smart contract considerations

Sports Trading Exchange | Founding Engineer / CTO | Remote USA | $140–200k + meaningful equity + founder seat available

We're building a peer-to-peer exchange where fans buy and sell positions in individual athletes, like a stock. Real money, central limit order book, mechanical settlement against a published rules-based rating computed from official on-field stats. There is no house. Fans trade against each other like a prediction market.

We are far along on everything except the build. Rating methodology is designed, legal structure is scoped with counsel, payments and data vendors are selected, and we ran a beta this past NFL season that drew ~1,000 organic users and 21,000 trades in four weeks. The founding team was part of Founders Inc, and we are about to open our seed round.

We are hiring the engineer who owns the entire technical build, with no inherited architecture and nobody between them and the problem:

Matching engine and order book
Rating and settlement engine, deterministic, computed from official stats
Ledger, custody, and the real-time data pipeline
Every architecture decision, including one we have deliberately left open: on-chain vs off-chain custody and settlement at v1

Looking for someone who has built correctness-critical, concurrent systems. Trading, exchanges, payments, or comparable. Language is open. We care about systems depth, not a specific stack. Two non-technical founders, so you would own the technical domain completely and be the technical voice with investors and eventually regulators.
