Choreograph is building the AI-powered routing intelligence layer for crypto transactions.

Today, every blockchain and rollup has its own fee markets, validators, and quirks — making it hard for wallets, payment providers, and dApps to guarantee cheap and reliable execution.

Choreograph solves this by providing real-time routing optimization through APIs that integrate seamlessly with existing payment infrastructure. Our machine learning models continuously monitor 15+ blockchain networks — tracking mempool congestion, gas prices, validator performance, and network conditions — to predict the optimal chain for each transaction.

The result: faster, cheaper, and more reliable crypto payments without changing how end-users interact with apps.

Looking for a Founding Engineer to help design and scale Choreograph’s routing engine. You’ll work across the full stack of blockchain infrastructure and applied ML, from low-level mempool watchers to prediction models and developer-facing APIs. As an early team member, you’ll have the chance to shape both the product and the company’s technical culture.

• Build and scale the real-time data pipeline that ingests gas prices, validator performance, and mempool data from 15+ chains.
• Design and train machine learning models that predict optimal execution paths (cheapest chain, fastest confirmation, highest reliability).
• Create developer-facing APIs and SDKs that make routing intelligence plug-and-play for wallets, payment providers, and dApps.
• Prototype and benchmark new optimization strategies (timing, cross-chain routing, paymaster selection).
• Collaborate with founders, design partners, and early customers to turn insights into production features.
• Help define Choreograph’s engineering culture and processes as an early member of the team.

• Strong background in backend engineering, distributed systems, or blockchain infra.
• Hands-on experience with Ethereum/L2 gas mechanics, mempools, and validator dynamics.
• Familiarity with cross-chain infra (bridges, rollups, token standards).
• Comfort with real-time data pipelines and ML model integration (Python/TypeScript preferred).
• Excitement about working in a fast-paced early-stage startup where you’ll own projects end-to-end.
• Bonus: Experience building APIs for developers (SDKs, REST/GraphQL, etc.).

• Impact: Shape the intelligence layer that will power the next generation of crypto payments.
• Tech frontier: Work at the intersection of account abstraction, L2 scaling, and applied ML.
• Ownership: Join as an early engineer with significant influence on product direction.
• Distribution: Your work will reach wallets, dApps, and payment providers across the crypto ecosystem.
