Systems Engineer

Design and implement high-performance systems components for Nexus's DEX engine and Layer 1 protocol runtime, optimizing execution paths, concurrency, memory, I/O, determinism, and throughput.

Responsibilities

• Design and implement high-performance components in Rust, C++, or Go
• Build low-latency pipelines for order execution, event propagation, and state updates
• Optimize concurrency, scheduling, memory layout, and I/O paths for determinism and throughput
• Contribute to execution abstractions for the protocol layer
• Work with protocol engineers on safety, composability, and consensus compatibility
• Investigate performance bottlenecks using profiling, tracing, and benchmarking
• Define standards for reliability, correctness, and high-assurance distributed execution
• Drive system design decisions and mentor others for senior or principal candidates

Requirements

• Strong experience with Rust, C++, Go, or other systems programming languages
• Understanding of high-performance or distributed systems
• Ability to reason about execution flows, concurrency models, resource lifecycles, and system invariants
• Practical experience profiling CPU, memory, and synchronization overhead
• Comfort working with performance, determinism, and resilience constraints
• Excellent spoken and written Business English
