About the Role

We’re looking for a Sr. Backend Engineer who wants to work on serious infrastructure. This isn’t a narrow feature role. You’ll own meaningful pieces of the stack, learn from senior engineers, and ship production code that gets used immediately. Expect high ownership, fast feedback loops, and real impact.

About the Team

The Archival team exposes APIs for querying Solana’s multi-petabyte ledger with sub-100ms. If you love the challenge of large datasets and low-latency performance engineering, this is the right team for you. The team moves fast, owns an enormous surface area, and operates like a small group of founders sitting in the critical path of the company.

What You'll Do

• Build ingestion, indexing, and retrieval features across our archival systems

• Improve API performance and reliability for high-throughput services

• Optimize query performance against databases like ClickHouse, Postgres, and RocksDB

• Collaborate with senior & staff engineers on caching, scaling, and distributed data patterns

• Debug, profile, and maintain production systems for performance

• Engage in system design, technical discussions, and long-term planning

What You'll Bring

• 3+ years of strong backend engineering experience

• Experience with Rust (strongly preferred), C++, or an equivalent language

• Professional experience with distributed systems, data pipelines, and performance-focused engineering

• Familiar with database schema design and optimization patterns for large datasets

• Ability to break down complex problems into simple solutions

• Relentless curiosity and a drive to dive deep into performance optimizations

• Desire for a fast-moving, high-ownership environment

Nice to Have

• Exposure to Solana, blockchain, or web3 infrastructure

• Experience with Postgres, ClickHouse, and/or RocksDB
