What You’ll Do

📍Design, implement, and optimize high-performance components in Rust, C++, or Go for Nexus’s DEX engine and protocol runtime. 📍Design, implement, and optimize all layers of the Nexus protocol stack, including consensus, execution, and API/RPC servers. 📍Build low-latency pipelines for order execution, event propagation, and state updates. 📍Design and implement financial and trading primitives on the Nexus L. 📍Optimize concurrency, scheduling, memory layout, and I/O paths for determinism and throughput. 📍Contribute to the evolution of execution abstractions that may be enshrined at the protocol layer. 📍Work with protocol engineers to ensure safety, composability, and consensus compatibility. 📍Investigate and resolve performance bottlenecks using profiling, tracing, and benchmarking techniques. 📍Help define standards for reliability, correctness, and high-assurance distributed execution. 📍For senior/principal candidates: drive system design decisions, shape execution architecture, and mentor others in performance engineering.

What We’re Looking For

📍Very strong systems engineering ability: writing modular, maintainable code within a complex codebase where correctness and performance are critical. 📍Experience with Rust (or C++/Go with strong performance focus). 📍Understanding of high-performance or distributed systems (e.g., low-latency engines, runtimes, databases, OS-level concurrency). 📍Ability to think in terms of execution flows, concurrency models, resource lifecycles, and system invariants. 📍Interest in performance optimization and low-level profiling (CPU, memory, synchronization overhead).
