Rust Engineer

Axiom Trade is building the future of retail trading. As opportunities migrate on-chain, Axiom's mission is to make discovering and trading digital assets fast, powerful, and intuitive. Serving millions of active users and facilitating more than $100M in daily trading volume, Axiom is operated by a high-ownership, fast-moving engineering team based in Austin. Role Summary Rust powers Axiom’s critical path across low-latency services, real-time data streaming, and trade execution. As a Rust Engineer, you will build and operate high-throughput backend services across 300k+ lines of code, index Solana and EVM chains in real time where sub-10ms latency makes a product difference, and design concurrent in-memory caching systems that shield underlying databases. Key Responsibilities Critical-Path Infrastructure: Build, operate, and scale production Rust services running continuously under heavy retail and market load.Real-Time Chain Indexing: Develop ultra-low-latency real-time indexing engines for Solana and EVM chains.Concurrency & Memory Management: Write async Rust using Tokio, optimizing concurrent in-memory state models to serve reads with minimal database overhead.Data Layer Optimization: Push Postgres, Redis, Kafka, and ClickHouse to their performance limits and select optimal data backends for varying workloads.Cross-Language Consistency: Maintain wire-level protocol and schema agreement between the Rust and TypeScript fleet services.Profiling & Performance Defense: Profile production code (flamegraphs, allocation pressure, tail latency) and uphold rigorous engineering standards. Requirements & Qualifications Must-Haves Production Rust: Deep production experience with asynchronous Rust and the tokio runtime ecosystem.Systems Foundations: Complete fluency with Rust ownership, lifetimes, borrow checker mechanics, and multi-threaded concurrency in production codebases.Load Reliability: Proven experience building, deploying, and maintaining services that operate continuously under sustained high concurrency and load.Execution & Ownership: Strong debugging fundamentals, high urgency, and comfort taking end-to-end ownership in a fast-paced environment. Nice-to-Haves Latency & Performance: Experience with low-level latency profiling, flamegraphs, memory allocation tuning, and optimizing p99 tail latency.Ecosystem Crates: Production background with sqlx, tokio-tungstenite, rdkafka, or Redis crates.In-Memory Concurrency: Hands-on experience with dashmap, arc-swap, or custom lock-free data structures.Streaming Ingestion: Experience with gRPC, Solana Geyser plugins, Redpanda/Kafka, or large-scale WebSocket fan-out architectures.Blockchain Internals: In-depth understanding of Solana or EVM execution environments, node RPCs, and on-chain mechanics. Compensation & Benefits Annual Base Salary: $320,000 – $465,000 USDBonus: Performance-based bonus structure
