About the role

Senior Systems Engineer role focused on high-performance, low-latency execution systems for Nexus’s Layer 1 protocol and DEX engine. Remote contract position for LATAM-based engineers collaborating with San Francisco teams to design, optimize, and evolve the execution stack.

Responsibilities

  • Design and implement high-performance components in Rust, C++, or Go for Nexus’s DEX engine and protocol runtime.
  • 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 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.

Qualifications

  • Strong experience with Rust, C++, Go, or other systems programming languages.
  • 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.
  • Practical experience profiling CPU, memory, and synchronization overhead.
  • Comfort working close to runtime constraints where performance, determinism, and resilience are critical.
  • Excellent communication skills in Business English (spoken and written).
