About the Role
About the Role
The Full Stack Developer (Rust) will be responsible for rewriting core components of a global equities execution platform using Rust. This role involves optimizing performance, implementing rigorous testing, and integrating AI-assisted workflows to enhance feature development.
What You'll Do
- 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.
Who You Are
- 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.
Bonus Points
- 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.
Benefits
- Opportunity to work on bleeding-edge projects.
- Work with a highly motivated and dedicated team.
- Competitive salary.
- Flexible schedule.
- Benefits package - medical insurance, sports.
- Corporate social events.
- Professional development opportunities.
- Well-equipped office.
