high-throughput, deterministic real-time systems in regulated environments.

Key Responsibilities

● Own end-to-end architecture of a high-performance trading platform.

● Design systems for ultra-low latency, high TPS, and predictable performance.

● Architect scalable, fault-tolerant distributed systems with zero-downtime principles.

● Drive active-active, multi-region architecture strategy and DR readiness.

● Lead performance benchmarking, tuning, and capacity planning.

● Establish architectural governance and engineering best practices.

● Collaborate with business, product, and compliance teams.

● Mentor senior engineers and lead architecture reviews.

Mandatory Experience

● 15+ years in backend/distributed systems engineering.

● Proven experience building ultra-low latency, high-scale systems.

● Mandatory 3-5 years of experience in stock broking / trading platforms / capital markets.

● Experience handling mission-critical systems with strict SLAs.

● Exposure to high-volume, real-time transaction systems.

Domain Expertise (Must Have – Broking Platforms)

Strong hands-on understanding of: Order & Execution

● Complete order lifecycle in broking (validation → risk checks → routing → exchange

acknowledgement → trade confirmation → settlement).

● Ultra-low latency trade routing and deterministic execution flows.

● Order state management, reconciliation, and audit trails.

Market Data & Charting

● Market feed ingestion (tick-by-tick data, LTP, depth).

● High-throughput feed processing and normalization.

● Real-time charting data pipelines and aggregation strategies.

Portfolio, Risk & P&L
