Rust Developer

Job Title: Low-Latency Rust Developer Location: Gurgaon Company: 39k Group – India’s Largest Crypto Trading Firm About 39k 39k Group is a high-frequency trading firm operating globally across centralized crypto exchanges. We specialize in ultra-low-latency strategies and market making, and we're scaling our infrastructure to handle billions of events daily with microsecond-level performance. Role Overview We’re hiring a Rust engineer with hands-on experience in building low-latency systems . You’ll work closely with traders and infra teams to write performance-critical components for our trading stack, including market data adapters, execution gateways, and simulation engines. What You’ll Do Design and build latency-sensitive systems in Rust that process millions of messages per second. Optimize for performance across the stack: CPU cache, memory allocation, lock-free data structures, and network IO. Build exchange connectors and event-driven pipelines for ingesting market data and sending orders with minimal jitter. Write multithreaded, asynchronous code that runs reliably under real-time constraints. Collaborate with strategy teams to simulate, test, and refine infrastructure under production-like load. Analyze latency across the wire, system, and application layers — and tune accordingly. What We’re Looking For 3–5 years of professional Rust experience , ideally in trading systems, embedded systems, or performance-critical infrastructure. Deep understanding of: Systems programming and memory management Lock-free programming, bounded queues, and async runtimes TCP/UDP, multicast, and event-driven network systems Prior experience building low-latency infrastructure (in trading, gaming, or real-time systems). Comfort with Linux , performance profiling tools, and writing testable code under production constraints. Bonus: Experience in C++, HFT systems, kernel bypass networking (e.g., DPDK, io_uring), or time sync (e.g., PTP, NTP). Why Join Us? Build systems that directly impact real PnL in live markets — no layers, no bureaucracy. Collaborate with world-class quants and traders on infrastructure that matters. Operate at the edge of crypto market structure — 24/7, real-time, and globally connected. Hybrid flexibility and outcome-driven culture. If you’re a systems engineer who sweats nanoseconds and loves Rust — this is the place to make your code count. Show more Show less
