Senior C++ Engineer

As a Senior C++ Engineer, you will contribute to the design, development, and optimization of our core real-time trading infrastructure. You will work on latency-sensitive components, ensure code quality, and collaborate with cross-functional teams to deliver robust and scalable solutions.

You will participate in technical discussions, contribute to system improvements, and ensure our C++ codebase continues to be a strong foundation for high-availability systems. While you will be expected to provide technical guidance and mentorship, this role is hands-on with a strong focus on coding, debugging, and performance tuning.

Prior experience in trading systems is highly preferred.

• Collaborate with traders and project managers to gain a deep understanding of mission-critical trading applications.
• Develop and maintain high-performance C++ components for real-time data processing, event handling, and command execution.
• Contribute to system design decisions around memory management, concurrency models, error recovery, and inter-process communication.
• Work with backend and frontend engineers to design efficient APIs and system boundaries across services.
• Conduct in-depth code reviews with a focus on performance, correctness, and maintainability.
• Identify performance bottlenecks and lead efforts in profiling and optimization.
• Mentor junior and mid-level engineers on design patterns, performance, and C++ best practices.
• Contribute directly to feature implementation, maintenance, and system improvements.
• Stay informed on industry trends and advancements in trading infrastructure and real-time systems.
• Foster a culture of technical ownership and transparency.

Requirements

• 7+ years of experience in C++ system-level development (ideally C++17 or newer)
• Proven experience designing low-latency, high-throughput, and highly available systems
• Deep understanding of threading models, memory layout, lock-free data structures, and CPU/cache behavior
• Proficiency with system-level debugging and profiling tools (e.g., perf, gdb, valgrind, sanitizers)
• Experience writing technical design documents and leading system-level architectural discussions
• Strong communication skills and ability to collaborate across backend and frontend teams
• Experience mentoring engineers and leading large-scale system design
• Experience in networking protocols (TCP, UDP, WebSockets) support
• Familiarity with event-driven architectures, asynchronous processing, and message queues/brokers (ex. ZeroMQ and/or Kafka)

• Knowledge of Python and/or Rust
• Background in crypto, high-frequency trading, or real-time market data systems.
• Experience designing and consuming gRPC or RESTful APIs
• Experience with relational databases (e.g., PostgreSQL, TimescaleDB)
• Familiarity with crypto exchange market data and order routing protocols
• Contributions to open-source projects or a strong technical blog/portfolio
• Experience with observability tools (e.g., Prometheus, Grafana, OpenTelemetry).

• CV Screening - We will review your application based on the qualifications and experience outlined above.
• HR Interview - To clarify any questions before technical assessment.
• First interview - Interview with the engineering team lead and senior engineers on experiences and motivation and generic technical questions
• Take Home Test - A practical exercise designed to evaluate your technical ability and simulate real-world technical challenges.
• Second Interview - Interview with VP of Engineering to delve into your resume and skills, and discuss your career goals
• Final Interview with the CIO - A concluding discussion to evaluate cultural fit, strategic alignment, and how you resonate with the firm's values.

Throughout the process, you'll be assessed for cultural fit through our company values:

• Drive – We seek people whose passion fuels relentless growth and a pursuit of excellence.
• Ownership – We value those who take initiative and treat the company's goals as their own.
• Judgment – We value individuals who focus on what matters and consistently drive meaningful results.
• Openness – We believe in honest dialogue, constructive challenge, and shared learning.
• Competence – We work with people who can thrive in fast-changing environments.
• Resilience – We stay calm under pressure, adapt quickly, and learn from setbacks.
