Job description
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: real-time chain indexers, per-chain search engines, the image and metadata pipeline, and the sockets that push it all to users.
- Build and operate the many Rust services behind the product, across 100k+ 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
- Concurrent in-memory state — dashmap, arc-swap, or lock-free structures
- Search and ranking systems
- Experience doing high-throughput streaming ingest from gRPC, Geyser, Kafka/Redpanda
- Experience developing systems with high throughput, bursty egress; especially for Websocket fanout to many clients
- Solana or EVM internals, whether indexing or on-chain
- Comfortable in TypeScript as well - much of the fleet is both
We encourage you to apply even if you do not meet every qualification.
Nice to have
- Experience with latency profiling and optimization.
- Familiarity with concurrent in-memory state management.
- Knowledge of search and ranking systems.
Responsibilities
- Build and operate Rust services for Axiom's trading platform.
- Index Solana and EVM chains in real time.
- Write async Rust with tokio for performance optimization.
- Utilize Postgres, Redis, Kafka, and ClickHouse effectively.
- Ensure Rust and TypeScript components are in agreement.
Focus areas
- Fintech
- Crypto
