Job Description
Systems Engineer, Contract
Nexus
• 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.
Job Requirements
- 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).
Benefits
- Competitive salary
- Work on systems where your optimizations translate directly into global performance gains
- Grow from mid-level contributor to system owner or drive execution architecture as a senior/principal
- Build the execution backbone of a Layer 1 blockchain and next-generation DEX engine
- Join a high-performance engineering culture where ambition and deep technical work are expected
