## Description

We are seeking an experienced C++ Developer to join our Information Technology team at Millennium, a global alternative investment firm.

The successful candidate will design, build, and operate high-performance C++ services that calculate real-time pricing, risk, and P&L across fixed income and credit instruments.

Responsibilities:

- Design, build, and operate high-performance C++ services that calculate real-time pricing, risk, and P&L across fixed income and credit instruments.

- Own service reliability end to end, including monitoring, alerting, incident response, and root cause analysis in a live production environment.

- Write thread-safe, exception-safe C++ code for concurrent, near-real-time workloads with hard latency targets.

- Optimize service performance by profiling hotspots, reducing memory allocations, improving cache behavior, and tuning throughput under load.

- Integrate C++ services with upstream and downstream systems using Kafka, Protobuf, and internal APIs.

- Contribute to CI/CD pipelines, including automated regression testing, A/B deployment, and blue/green release management.

- Promote engineering best practices through code reviews, exception safety, RAII patterns, and robust error handling in a multithreaded environment.

Requirements:

- Bachelor’s degree in Computer Science, Software Engineering, or a related discipline; advanced qualifications are a plus.

- Previous experience developing C++ services or systems.

- Strong hands-on experience with modern C++ (C++17/C++20), including move semantics, smart pointers, RAII, templates, and constexpr.

- Solid understanding of multithreading and concurrency, including mutexes, atomics, lock-free structures, thread pools, and race condition debugging.

- Experience building and operating long-running backend services, along with familiarity with service-oriented architecture, message queues such as Kafka, and serialization frameworks such as Protobuf or FlatBuffers.

- Proficiency with Linux, GDB/LLDB, profiling tools such as perf, Valgrind, and AddressSanitizer, and CI/CD pipelines.

- Strong analytical, troubleshooting, and communication skills, including the ability to diagnose production issues under pressure and collaborate across teams in a fast-paced environment.
