Establish and enhance comprehensive data‑quality controls, including validation, monitoring, and resilience mechanisms.
Build and maintain Python-based APIs and data pipelines to enable seamless integration, analytics, and downstream consumption.
Influence and contribute to architectural design decisions, engineering standards, and best practices for a centralised, firm‑wide market data platform.
Requirements
Over 6 years of hands-on experience in software engineering with a strong focus on real‑time data platforms and distributed system design.
Advanced proficiency in modern C++, including C++14, C++17, and C++20, with a deep understanding of performance‑oriented programming.
Proven expertise in low‑latency system development, optimisation, and troubleshooting.
Extensive background in building market data feed handlers for both major vendors (Refinitiv, Bloomberg, etc.) and direct exchange protocols such as FIX/FAST, ITCH, and OUCH.
Strong knowledge of real‑time data distribution architectures, network transport protocols (TCP, UDP, multicast), and high‑performance messaging technologies including Aeron, ZeroMQ, and Kafka.
Bachelor's or Master's degree in Computer Science, Engineering, or a closely related technical discipline.
