About Axiom Axiom is building the future of retail trading. As more opportunities move onchain, our mission is to make discovering and trading assets fast, powerful, and intuitive. Today, Axiom serves millions of users and facilitates more than $100M in daily trading volume. We are a small, fast-growing team based in Austin, with high ownership, urgency, and an obsession with exceptional products. About the Role Rust runs Axiom's critical path for a variety of features and systems.

• Build and operate the Rust services behind the product, across 300k+ lines and growing

• Index Solana and EVM chains in real time, where ten milliseconds is a product difference

• Write async Rust with tokio, and the concurrent in-memory state that keeps reads off the database

• Push Postgres, Redis, Kafka, and ClickHouse hard, and recognize when each is the wrong tool

• Keep the Rust and TypeScript halves of the fleet in exact agreement on the wire

• Profile what you ship and defend the numbers

• Raise the engineering bar through strong judgment and mentorship

Minimum Qualifications

• Production experience with async Rust and tokio

• Fluency with ownership, lifetimes, and concurrency in real codebases

• Excellent programming and debugging fundamentals

• Experience with services that run continuously under load

• Comfortable working with high ownership in a fast-moving environment

Preferred Qualifications

• Latency work: profiling, flamegraphs, allocation pressure, tail latency

• sqlx, tokio-tungstenite, rdkafka, or the redis crate in production

• Concurrent in-memory state - dashmap, arc-swap, or lock-free structures

• Search and ranking systems

• Streaming ingest: gRPC, Geyser, Kafka/Redpanda, or WebSocket fan-out

• Solana or EVM internals, whether indexing or onchain

• Comfortable in TypeScript as well - much of the fleet is both

We encourage you to apply even if you do not meet every qualification. Compensation Annual Salary: $320,000 - $465,000 USD
