Job Description:

We are seeking a highly skilled Senior C++ Developer to join our Core Engineering team building our next-generation market making and execution systems across both centralized (CeFi) and decentralized (DeFi) crypto exchanges.

You will design and optimize ultra-low-latency trading infrastructure, working closely with quantitative developers and traders to push the limits of performance, reliability, and scalability.

Key Responsibilities:

1. Design, develop, and maintain high-performance, low-latency C++ systems for market making and algorithmic trading.
2. Implement parallel and lock-free data structures to optimize throughput and minimize latency.
3. Leverage modern C++ (C++17/20) features for compile-time programming, template metaprogramming, and RAII-based memory/resource safety.
4. Optimize CPU cache usage, memory allocation patterns, and network I/O.
5. Collaborate with researchers and quants to translate trading strategies into production-ready code.
6. Design efficient data pipelines for real-time market data ingestion and order execution.
7. Ensure system reliability and performance through profiling, benchmarking, and stress testing.
8. Deploy and manage services on AWS, leveraging CI/CD and GitOps workflows for seamless delivery.
9. Participate in code reviews, contribute to architecture decisions, and mentor junior developers.

Requirements:

1. Bachelor's degree in Computer Science, or a related field. (Masters or PhD would be an advantage)
2. Strong proficiency in Modern C++ (preferably C++17 or later), STL, and templates.
3. Solid understanding of computer architecture, concurrency, and low-level system optimization.
4. Hands-on experience with multi-threaded and lock-free programming.
5. Deep knowledge of RAII, memory management, and compile-time programming (constexpr, SFINAE, concepts).
6. Strong grasp of data structures, algorithms, and network programming (sockets, epoll, etc.).
7. Excellent communication skills and ability to work collaboratively in a team environment.
8. Familiarity with low-latency design patterns, including busy-wait loops, memory pools, and bounded queues.
9. Experience integrating with exchange APIs (WebSocket, FIX, REST) for market data and order execution.

Preferred:

1. Prior internship or work experience on the buy-side in crypto, finance, quantitative analysis, or a related field.
2. Familiarity with DeFi protocols, smart contract interaction, or on-chain data integration.
3. Exposure to Python for tooling and scripting.
4. Experience with AWS (EC2, S3, etc.), CI/CD pipelines, and GitOps workflows.

Benefits

• Competitive salary & annual performance based incentives
• Benefits package including Health insurance and performance based incentives.
• Opportunities for professional development and growth.
• Exposure to cutting-edge quantitative analysis techniques and tools.
• Collaborative and supportive team environment.
• Work-life balance with flexible working arrangements.
