About this role
**Clear Street — Senior / Staff Software Engineer (Algorithmic Execution Platform)** ## About Clear Street Clear Street is modernizing the brokerage ecosystem. Founded in 2018, the company is replacing legacy capital markets infrastructure with a cloud-native clearing and custody system built for today’s complex, global markets. ## The Team The **Algorithmic Execution Services** team builds Clear Street’s electronic trading platform, delivering best execution across **equities, options, and futures** in **U.S. and international markets**. The team focuses on **low-latency order routing**, **algorithmic strategies**, **smart order logic**, **direct market access**, and **real-time risk controls**. ## The Role This is a **core infrastructure** role on a small, focused team, **hybrid (4 days in office)** out of **New York, NY** or **Lisle, IL**. You’ll be a foundational engineer shaping and building a **new execution platform**: a **low-latency, C++-based** system with **client-facing FIX connectivity**, **institutional-grade risk controls**, and deep integration across **U.S. exchanges and dark venues**. ### Key Responsibilities - **Client-facing FIX gateway**: Design and harden the FIX acceptor as the primary inbound order entry point. Own the full order lifecycle (entry, fills, ACKs, rejects, outbound sequencing). - **Market data infrastructure**: Build and maintain production-grade feed handlers for exchange protocols (**ITCH, OUCH, binary**) across major U.S. exchanges and ATSs, replacing legacy dependencies with proprietary low-latency infrastructure. - **Execution and venue connectivity**: Build and optimize the venue connectivity layer. Own latency profiling and hot-path analysis from order receipt through exchange acknowledgment. - **Pre-trade risk controls**: Architect and implement real-time risk checks with clear placement in the critical path, balancing correctness with **microsecond-level latency budgets**. - **Platform infrastructure**: Contribute to configuration/command & control architecture, normalized internal message representation, and audit-trail logging. - **Algorithmic strategy migration**: Over time, help migrate existing strategies off legacy infrastructure onto the new platform component-by-component until fully replaced. As the platform stabilizes over the next **12–24 months**, you’ll have opportunities to contribute to a broader roadmap, including a **research/backtesting environment**, expansion into additional asset classes (**options, futures, FX, crypto**), and support for **international markets** (e.g., Europe and Canada). ## What We Value - Bias toward action and sound tradeoffs with incomplete information - Deep ownership: care about correctness and performance beyond your immediate scope - Strong communication across engineering, trading, and operations - Willingness to challenge assumptions and raise the bar on how we build ## Requirements - **7+ years** building high-performance, low-latency **C++** systems in production - Deep knowledge of **FIX (4.2/4.4)** and the full order lifecycle (entry, routing, execution, cancellation, reporting) - Experience with exchange market data protocols (**ITCH, OUCH, binary**) and production-grade feed handlers - Strong understanding of low-latency architecture (kernel bypass, lock-free structures, CPU affinity, memory layout, hot-path profiling) - Experience with multicast messaging (e.g., **Aeron, LBM**, or equivalent pub/sub) - Solid grasp of U.S. equit
