About the Role

As a Rust Engineer at TechShack, you will develop ultra-low-latency trading systems that are critical for performance in a leading prop trading firm. You will work on high-throughput infrastructure and collaborate with a senior team to optimize trading systems and improve stability under high load.

What You’ll Work On

You’ll join a senior team owning the core of the trading stack, designing and optimising performance-critical trading systems: execution engines, market data handlers, matching logic and order routing.
Driving low-latency networking: kernel tuning, CPU/NIC optimisation, lock-free / wait-free designs, and careful memory management.
Writing high-performance Rust or C++ in production, with a focus on determinism, profiling and micro-optimisation where it matters.
Collaborating directly with traders, quants and crypto engineers to translate trading ideas into robust, scalable infrastructure.
Analysing live performance data to squeeze out microseconds, remove bottlenecks, and improve stability under high load.

Core Requirements

4+ years’ systems engineering experience.
Proven HFT / low-latency trading background (prop shop, market maker, tier-one hedge fund or similar).
Strong hands-on in Rust or C++ (Go also considered) in genuinely performance-critical environments.
Deep understanding of network stack behaviour (TCP/UDP, multicast, kernel bypass a plus).
Latency & throughput constraints in real trading systems.
Experience with live trading infrastructure – market data, execution, risk, or routing systems.

Bonus Requirements

Crypto trading system experience (CEX or DEX) or other 24/7 venues.
Commercial Rust experience in trading or high-performance infra.
Knowledge of exchange protocols (FIX, binary feeds, multiplexed WebSockets).
History of building or optimising high-volume execution or low-latency routing to CEX/DEX venues.
