Full Stack Developer (Rust)

Essential functions

• Rewrite Core Execution Systems: Architect and build core equities execution platform components using allocation-free, close-to-the-metal Rust.

• Optimize Hot-Path Performance: Eliminate tail latency and jitter by leveraging mechanical sympathy, NUMA awareness, and kernel bypass techniques.

• Build Deterministic Replay & Testing: Implement rigorous property-based tests, simulation tools, and deterministic replay to guarantee absolute system reliability.

• Leverage AI-Assisted Workflows: Integrate modern AI tooling (e.g., Claude Code) to accelerate feature development without compromising code quality.

• Drive Technical Benchmarking: Measure latency distributions, analyze histograms, and clearly articulate performance and architectural trade-offs.

Qualifications

• Hot-Path Architecture & Design: Architect, build, and optimize high-throughput, low-jitter Rust systems on the critical execution path.

• Low-Level Performance Tuning: Write zero-allocation, contention-aware code while managing CPU caches, memory layouts, and hardware affinity.

• Network & OS Optimization: Leverage kernel bypass, busy-polling I/O, and NUMA-aware memory management to strip latency out of the network path.

• Deterministic Testing & Reliability: Implement property-based testing, deterministic replay, and simulation environments to ensure flawless system reliability.

• AI-Assisted Delivery: Integrate modern AI engineering tooling (e.g., Claude Code) to accelerate development workflows without compromising quality.

Would be a plus

• Equities Market Structure: Knowledge of Cash Equities, Prime Brokerage, Order Management Systems (OMS), Smart Order Routing (SOR), or FIX protocol (Strongly Preferred).

• HFT / Market Data Systems: Hands-on experience with matching engines, exchange feeds, or HFT-grade systems.

• Async Rust / Tokio: Experience using Async Rust and Tokio for control-plane logic, monitoring, and tooling (distinct from the critical path).

• Open Source: Contributions to open-source Rust, systems-level, or low-latency frameworks.
