Software Test Engineer (Real-Time Trading Systems)

We are seeking a highly motivated Software Test Engineer to validate and ensure the performance and reliability of complex, real-time, distributed financial trading systems. This role involves working with large-scale, low-latency systems in the financial trading domain.

• Bachelor’s degree or higher in Computer Science or a related field.
• Proficiency in modern C++ (C++14/20) sufficient to read, understand, and debug production systems.
• Experience working with complex, distributed, and resilient systems, including fault tolerance, backpressure, retries, idempotency, and graceful degradation.
• Proven ability to debug and analyze issues in multi-threaded, high-performance systems.
• Experience with automated functional and performance testing (3+ years preferred).
• Experience building automated test frameworks.
• Proficiency in Python or similar scripting languages for test automation.
• Hands-on experience with both Linux and Windows-based development environments.
• Familiarity with version control systems (e.g., Git).
• Strong understanding of concurrency, synchronization, multithreading, and networking fundamentals (TCP/IP, latency, throughput).
• Experience with network diagnostic tools (e.g., Wireshark).
• Demonstrated ability to effectively use AI tools to improve productivity, system understanding, and debugging outcomes.
• Excellent problem-solving skills and attention to detail.
• Strong communication skills and ability to work across multiple teams.
• Highly self-driven, proactive, and capable of independently ramping up on complex systems.

Nice to have:

• Strong programming experience in C++ beyond debugging.
• Experience with financial systems, trading platforms, or high-frequency trading environments.
• Experience testing low-latency, high-throughput systems.
• Familiarity with Kafka or similar messaging systems.
• Familiarity with AWS and cloud-based microservices architectures.
• Familiarity with SQL and database validation techniques.
• Experience with containerization and DevOps practices (Docker, CI/CD, deployment pipelines).
• Understanding of system security, encryption, and performance trade-offs.
• Exposure to frontend/backend integration or full-stack systems.

• Develop a deep understanding of complex, distributed trading system architectures and data flows.
• Design and implement end-to-end automated test suites for functional, integration, and performance testing.
• Execute tests in specialized high-load environments to identify bottlenecks, latency issues, and failure points.
• Analyze system behavior under stress and proactively identify performance and scalability issues.
• Debug complex issues and drive root cause analysis across distributed, multi-threaded components.
• Document detailed test cases, test results, and defects, ensuring clear reproducibility.
• Collaborate closely with cross-functional engineering teams to track, prioritize, and resolve issues.
• Build and maintain automated testing frameworks and environments.
• Continuously improve testing methodologies, tooling, and processes.
• Leverage AI tools extensively to accelerate ramp-up on complex systems, generate and expand test scenarios, assist in debugging and log analysis, and support root cause investigation.
