Sr Systems Engineer Company: Nexus Nexus is the engine for verifiable finance — a blockchain designed to natively embed the world’s financial system into one compounding system. Built to support every major financial market on a single global exchange, Nexus unifies infrastructure that has historically been fragmented across chains and intermediaries. Headquartered in San Francisco with a growing presence in Buenos Aires, the team includes engineers, cryptographers, and market builders. Applicants must be located in Latin America. 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 become protocol primitives. - Work with protocol engineers to ensure safety, composability, and consensus compatibility. - Investigate and resolve performance bottlenecks using profiling, tracing, and benchmarking. - (Senior/Principal) Drive system design decisions and mentor others in performance engineering. Requirements: - Strong experience with Rust, C++, Go, or other systems programming languages. - Understanding of high-performance or distributed systems (low-latency engines, runtimes, databases, OS-level concurrency). - Ability to reason about execution flows, concurrency models, resource lifecycles, and system invariants. - Practical experience profiling CPU, memory, and synchronization overhead. - Excellent communication skills in Business English (spoken and written). Nice to have: - Experience building matching engines, databases, compilers, blockchain runtimes, or HPC systems. - Familiarity with lock-free concurrency, zero-copy data structures, or cache-aware design. - Exposure to protocol engineering, consensus systems, or transaction ordering. - Background in correctness-focused engineering (formal verification, static analysis). - Open-source contributions to systems-level projects. Stack: Rust, C++, Go Benefits: - Build the execution backbone of a Layer 1 blockchain and next-generation DEX engine. - Work on systems where optimizations translate directly into global performance gains. - Opportunity to grow from mid-level contributor to system owner or drive execution architecture as a senior. - Join a high-performance engineering culture; estimated compensation: $88k - $150k (estimated). 📩 Apply
