C++ Developer (Backend)

We are looking for a skilled C++ Developer (Backend) who will own and develop a low-latency trading system for the crypto market. The goal is to work on real-time order routing systems, execution systems, market data integration, configuration based on a DB, and WebSockets / HTTP APIs that are tailored to clients.

This position is best suited to engineers who are passionate about performance-critical systems, the foundation of trade and production, rather than reliability.

Key Responsibilities

• Implement and optimize the business intelligence on core Trading Components: order management, execution, risk, order state, and market-data pipelines.
• Low latency real time event pipelines (orders/market data), SPSC queues, and event buses
• Store and maintain exchange connectivity (REST/WebSocket, FIX) for order execution & market-data feeds
• All services should have DB-driven configuration sync and atomic snapshot persistence.
• Design framework for building WebSocket/HTTP APIs on orders, trades, positions, and market-data streams with client scoping.
• Debug production issues in C++ services, databases (SQL & NoSQL), and deployment environments.
• Increase the reliability, performance, and observability of trading and data infrastructure.

Required Skills

• Advanced modern C++ (C++17 or newer).
• Knowledge of multithreading, lock-free/SPSC queues, and low-latency design
• Strong understanding of trading concepts – orders, trades, positions, routing risk, and Market data (books, ticks, normalization)
• Familiarity with PostgreSQL and schema evolution
• JSON/TOML parsing and configuration management.
• Troubleshooting and debugging Linux systems running the system

Mandatory Skills

• Prior experience building HFT or other latency-sensitive systems is a strong plus.

Nice to have

• Experience with the FIX protocol.
• Knowledge of WebSocket servers (e.g., ixwebsocket).
• Familiarity with crypto exchange APIs (order and market data).
• Familiarity with fixed-point arithmetic and numerical precision.

What You’ll Own

• You will be responsible for WebSocket subscriptions with client-centric orders/transfers/bitcoins.
• Synchronization of routing rules from DB to atomic TOML updates.
• Progeny/heritage tree: To snap a picture.
• Solving problems of mismatched sessions between LPs and complex edge cases where child nodes can be routed.
