About the Role
Role Summary
As a Backend Engineer, you will set the technical direction for Axiom’s core backend infrastructure. You will design, build, and operate ultra-low-latency APIs, indexers, and real-time streaming pipelines, owning end-to-end performance, throughput, and correctness for mission-critical systems under constant high write loads.
Key Responsibilities
- Core Backend Architecture: Set technical direction and architect low-latency APIs, indexing layers, and streaming pipelines powering the core trading product.
- Throughput & Reliability: Own system latency, throughput, and state correctness under continuous, heavy write loads and market volatility.
- High-Volume Data Design: Design robust data schemas and advanced caching strategies across Postgres, Redis, and ClickHouse.
- Multi-Chain Execution: Build and scale services across multiple blockchain networks, including Solana, BNB Chain, Ethereum, Base, and emerging L2s.
- Production Observability & Triage: Rapidly debug production incidents across services, databases, and node/RPC infrastructure.
- System Simplification: Continuously refine fleet architecture to keep systems simple, maintainable, and highly operable while mentoring peers.
Requirements & Qualifications
Must-Haves
- Backend Mastery: Deep production experience building and scaling high-throughput backend services and distributed architectures (TypeScript or Rust).
- Data Layer Depth: Advanced expertise in data modeling, query optimization, and caching strategies with Postgres, Redis, and ClickHouse.
- High-Load Performance: Proven track record designing APIs and streaming architectures that maintain low latency under heavy concurrency.
- Operational Excellence: Strong debugging fundamentals across production services, RPC nodes, and database layers.
- High Ownership: Urgency, autonomy, and an obsession with shipping reliable, user-focused software.
Nice-to-Haves
- Hands-on experience with on-chain data extraction, indexing engines (Solana Geyser, EVM logs), and mempool mechanics.
- Background in high-frequency trading platforms, order books, DEX aggregators, or high-volume fintech APIs.
Compensation & Benefits
Annual Base Salary: $320,000 – $465,000 USD
