C++ Developer (Backend)

Were looking for a C++ engineer to own and evolve a low-latency for crypto trading. Youll work on real-time order routing, execution, market-data integration, DB-backed configuration, and client-scoped WebSocket/HTTP APIs.

Job Location: Noida, India

Key responsibilities:

Design and optimize core trading components: order management, execution, risk, order state, and market-data pipelines.

Implement low-latency real-time event pipelines (SPSC queues, event buses) for both orders and market data.

Integrate and maintain exchange connectivity (REST/WebSocket, FIX) for order execution and market-data feeds.

Implement DB-driven configuration sync and atomic snapshot persistence across services.

Build WebSocket/HTTP APIs for order, trade, position, and market-data streaming with client scoping.

Debug production issues across C++ services, databases, and deployment environments.

Improve reliability, performance, and observability of trading and data infrastructure.

Required Skills:

Strong modern C++ (C++17 or later).

Experience with multithreading, lock-free/SPSC queues, and low-latency design.

Solid understanding of trading concepts: orders, trades, positions, routing, risk, and market data (books, ticks, normalization).

Experience with PostgreSQL and schema evolution.

JSON/TOML parsing and configuration management.

Linux production debugging and systemd-based deployments.

Nice to Have:

Experience with the FIX protocol.

Familiarity with WebSocket servers (e.g. ixwebsocket).

Working knowledge of crypto exchange APIs (order and market-data).

Knowledge of numerical precision and fixed-point arithmetic.

Work Youd Own:

WebSocket subscription model: client-scoped deltas (orders/trades/positions).

Routing rules synced from DB atomic TOML updates.

Parent/child order trees in order snapshots.

Fixing LP/session name mismatches and routing edge cases.

Bonus

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