You will work closely with traders, quants, and other engineers to deliver high-performance, reliable, and scalable trading platforms.

This role is ideal for someone who thrives in high-stakes, low-latency environments, has strong systems-level engineering experience, and enjoys tackling performance bottlenecks and large-scale distributed systems problems.

Key Responsibilities:

• Design and implement high-performance trading infrastructure, including order management systems, execution gateways, and market data distribution.
• Optimize low-latency systems for throughput, determinism, and fault tolerance.
• Integrate with global exchanges, brokers, and ECNs, ensuring robust FIX/FAST/OUCH/ITCH connectivity.
• Build real-time risk checks and margin controls aligned with compliance requirements.
• Develop and maintain core libraries, APIs, and frameworks used across trading desks.
• Collaborate with quants and traders to prototype and productionize new strategies.
• Monitor, debug, and optimize production systems to ensure high availability and rapid recovery.
• Mentor junior engineers and set engineering standards for code quality, testing, and deployment.

Qualifications:

• Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.
• 7+ years of software engineering experience, with at least 3 years in trading, fintech, or high-performance systems.
• Strong programming skills in Go, C++, or Java; Python experience.
• Deep understanding of operating systems, networking, and concurrency.
• Proven experience in low-latency optimization and performance tuning.
• Familiarity with FIX, OUCH, ITCH, or other trading protocols.
• Experience building distributed, fault-tolerant systems.
• Solid knowledge of databases, caching, and messaging systems (Postgres, Redis, Kafka, RabbitMQ, etc.).
• Strong problem-solving skills, attention to detail, and ability to work under pressure.

Preferred Skills:

• Experience with equities, derivatives, or FX trading systems.
• Knowledge of cloud, containerization, and orchestration tools (Kubernetes, Docker).
• Experience with observability stacks (Prometheus, Grafana, ELK).
• Contributions to open-source projects in systems programming or infrastructure.
