Real-Time Quantitative C++ Developer

Millennium; New York (NY); On-site; USD 175,000 - 250,000; Full time

Job summary

Millennium is seeking a Quantitative Developer in New York to design, build, and operate high-performance C++ services that support real-time pricing, risk, and P&L for fixed income and credit instruments.

You will own end-to-end service reliability in production, optimize performance, and integrate with Kafka, Protobuf, and internal APIs. Proficiency in Linux, modern C++, and CI/CD is required, with up to 5 years of backend experience.

Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or related field; advanced qualifications are a plus.
• Up to 5 years of professional C++ service/systems development with modern C++ (C++17/20).
• Strong understanding of multithreading, mutexes, atomics, and race condition debugging.
• Experience building and operating long-running backend services, not just libraries or batch jobs.
• Familiarity with Kafka, Protobuf/FlatBuffers, and microservice architectures; Linux and CI/CD tooling are a plus.

Responsibilities

• Design, build, and operate high-performance C++ services that compute real-time pricing, risk, and P&L across fixed income and credit instruments.
• Own service reliability end-to-end: monitoring, alerting, incident response, and root cause analysis in production.
• Write thread-safe, exception-safe C++ code for concurrent, near-real-time workloads with hard latency targets.
• Optimize service performance by profiling hotspots, reducing allocations, and tuning throughput under load.
• Integrate C++ services with Kafka, Protobuf, and internal APIs.
• Contribute to CI/CD with automated tests, A/B deployment, and blue/green releases.
• Promote engineering best practices: code review, RAII, and robust error handling in multi-threaded environments.
