Senior C++ Developer

Project description: Our team develops and evolves infrastructure services that orchestrate large-scale analytic price and risk computations across a wide range of financial instruments. These calculations are distributed over thousands of computation engines, enabling both high-throughput End-of-Day batch processing and low-latency intraday streaming analytics.

The core analytic engine is implemented in C++, while the surrounding orchestration services are written in Java (legacy) and Python. We’re transitioning our environment from Windows-based virtual machines to containerized deployments on Kubernetes and Linux. Communication between services is primarily handled via Solace messaging and REST APIs.

A major focus of our work is ensuring reliability and performance in a complex distributed system- including extensive debugging, monitoring, and log analysis to identify and resolve issues across multiple services and environments.
