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.
Responsibilities
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
Must Have
- 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)
Nice to Have
- 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)
Interview Process
- 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
