Helius is building the core infrastructure for Solana - empowering developers to create the next generation of crypto-powered applications. Our mission is to accelerate the development of internet capital markets by making it easier, faster, and more intuitive to build on-chain.
Thousands of teams - from early-stage startups to industry leaders like Coinbase, Phantom, and Jupiter - rely on Helius APIs, webhooks, and indexing tools to power their products. Backed by Haun Ventures, Founders Fund, and Foundation Capital, we’re a small, senior team obsessed with performance, simplicity, and scalability in decentralized systems.

We're looking for a Staff Performance Engineer to own the most latency-critical systems at Helius. These services are responsible for streaming Solana's state changes across our global network and providing real-time data APIs to traders, exchanges, and DeFi protocols. They handle massive throughput, and small optimizations create outsized impact. You'll lead performance strategy, drive cross-team architectural decisions, and dig into the hardest bottlenecks to make our products faster and more efficient. The problems are challenging, the expectations are high, and the improvements you ship will be felt across the Solana ecosystem.
