We operate at the intersection of high performance, correctness, resilience, and scale—where every design decision matters. We are seeking a Senior C++ Software Engineer to lead the design and evolution of our trading counter and core trading systems. This role is for an engineer who combines deep systems expertise with strong ownership: someone who investigates root causes, raises the quality bar across the engineering lifecycle, and turns individual learning into reusable team capability. ## What You’ll Be Doing - Lead the architecture, design, and development of complex, high-performance C++ trading systems. - Design reliable distributed systems, including consistency, fault tolerance, disaster recovery, and resilience strategies across system boundaries. - Own work end to end—from technical proposals and design reviews through framework refactoring, implementation, deployment, production debugging, replay, and validation. - Solve low-level systems challenges involving networking, protocols, concurrency, memory management, performance, and operating-system-level behaviour. - Drive architectural improvements by identifying systemic issues and anti-patterns, such as overly coupled or “God Class” designs, and redesigning components with clear responsibilities. - Build proactive quality safeguards, including automated testing, failure-injection scenarios, stability validation, monitoring, and replay-based verification. - Design controlled experiments to validate architectural assumptions and diagnose complex production issues beyond surface-level symptoms. - Work effectively across heterogeneous technology stacks, making sound engineering decisions at language, service, and platform boundaries. - Independently explore and apply AI-assisted engineering practices across code understanding, solution design, cross-review, incident analysis, test validation, and knowledge capture. - Raise engineering standards through thoughtful code reviews, technical discussions, and continuous improvements to development practices. - Mentor engineers and share practical knowledge through documentation, playbooks, technical sessions, and reusable frameworks. ## What We Look For In You - Bachelor’s degree or above in Computer Science, Software Engineering, or a related STEM field; equivalent practical experience is also valued. - 5+ years of hands-on software engineering experience, with substantial experience building production C++ systems. - Strong experience designing and evolving complex systems, with a clear understanding of architectural trade-offs. - Proven knowledge of concurrency, multithreading, network programming, and performance optimisation in Linux-based environments. - Hands-on experience with distributed consistency, high availability, fault tolerance, disaster recovery, or other system-level reliability designs. - Strong understanding of computer systems fundamentals, including networking protocols, operating systems, memory, storage, and runtime behaviour. - A track record of taking ownership proactively, from defining the problem to delivering and validating a robust solution. - Exceptional debugging and analytical ability, with a habit of investigating why issues occur—not simply applying short-term fixes. - Experience using automated tests, simulation, replay, or comparative experiments to validate system behaviour and reliability. - Clear communication skills and a collaborative mindset; able to turn experience into documentation, standards, and practices that help the whole team. Nice to Haves - Experience with exchange, brokerage, trading counter, order management, execution, market data, or other low-latency financial systems. - Experience with event-driven architectures, messaging systems, or high-throughput distributed platforms. - Familiarity with Rust, Java, Go, Python, or other languages used in multi-language production environments. - Practical experience applying AI tools to improve software engineering workflows and code quality. - Experience working with globally distributed, cross-functional engineering teams. ## Perks & Benefits - Competitive total compensation package - L&D programs and Education subsidy for employees' growth and development - Various team building programs and company events - Wellness and meal allowances - Comprehensive healthcare schemes for employees and dependants - More that we love to tell you along the process!
