Description :

Job Title : Senior C++ Low Latency Engineer

Location : Remote

Experience Level : 8+ years

Department : Market Data / Technology

Employment Type : Full-time

Role Summary :

Join us at the start of a green-field initiative to design and build a next-generation ultra-low-latency Market Data platform that will power our real-time services. You will work on systems where every microsecond matters, integrating binary exchange protocols and delivering software engineered for speed, correctness, and reliability.

You will collaborate within a highly skilled, distributed engineering team across two locations, shaping a platform built for performance, quality, and long-term maintainability.

What You Will Do :

- Design and develop core components of a low-latency Market Data platform.

- Implement and optimize market data feed handlers using TCP and multicast UDP binary protocols.

- Integrate and maintain feeds such as ITCH, SBE, FAST, FIX, and venue-specific formats.

- Build and maintain L1, L2, and L3 order books, including conflation, correlation, consolidated tapes, and replay pipelines.

- Drive performance optimization with deep focus on :

1. CPU cache hierarchies and memory locality

2. NUMA-aware design and predictable execution

3. Data-structure layout and allocation-free paths

4. Branch prediction, prefetching, and TLB behavior

5. NIC tuning and kernel network stack optimization

- Build and maintain high test coverage, including latency regression and deterministic behaviour tests.

- Validate end-to-end correctness and quality of Market Data flows.

- Perform profiling and instrumentation using eBPF, perf events, and flame graphs.

- Analyze binary protocol dumps and low-level hexdump traces to diagnose issues.

- Deploy, test, and validate software in QA and Production environments.

- Participate in on-call rotation and incident support once the platform is live.
