Backend Engineer
HyperLink is a prime brokerage layer for Hyperliquid, giving power users faster execution, lower fees, and private trading flow without leaving Hyperliquid's orderbook. It serves active and serious Hyperliquid traders who want better execution and reduced fee tiers.
About HyperLink
HyperLink is a trading gateway and prime broker built specifically for Hyperliquid power users. It lets traders execute directly on Hyperliquid's full orderbook at native speeds (~10ms added latency) while keeping funds in a non-custodial, hardware-isolated smart contract that HyperLink itself never controls. By pooling the trading volume of all its users into a single shared contract, HyperLink pushes traders into higher Hyperliquid volume tiers automatically, lowering fees, while also reducing information leakage that would otherwise expose an individual trader's timing, size, and positions. The platform mirrors the Hyperliquid API (available at api.hyperlink.xyz), so existing trading strategies built with the same order structures, EIP-712 signing, and asset indexes can migrate with minimal changes. HyperLink's execution infrastructure is audited and designed to be fully auditable via remote attestation, targeting active traders and quant/algorithmic strategies running significant volume on Hyperliquid.
Skills
About the Role
You will design and implement high-performance backend services in Rust, develop and optimize smart contracts for the HyperEVM, and build real-time trading infrastructure that meets sub-millisecond latency requirements. You will work with TEEs and privacy-preserving cryptography, diagnose performance bottlenecks, and design robust distributed systems. You will write production-quality code, optimize for throughput and latency, and contribute to protocol and system architecture decisions.
Requirements
- Strong proficiency in Rust and systems programming
- Exposure to high-throughput trading systems
- Experience with high-performance low-latency systems
- Understanding of blockchain and smart contract development
- Ability to work on complex distributed systems
- Passion for building robust scalable infrastructure
Responsibilities
- Design and implement high-performance backend services in Rust
- Build and optimize smart contracts for the HyperEVM
- Develop real-time trading infrastructure with sub-millisecond latency
- Collaborate on protocol architecture and system design
