Technical Architect Trading Platform

Capital Markets Technology | Ultra-Low Latency Systems | Distributed Architecture | High-Scale Engineering

Experience: 15+ Years

Location: Gurgaon

Employment Type: Full-Time

About the Role

We are hiring a Technical Architect to design and scale a mission-critical, ultra-low latency stock broking platform built for massive scale and peak market volatility. The role calls for deep capital markets expertise and the ability to architect high-throughput, deterministic real-time systems in regulated environments.

Key Responsibilities

Architecture & Platform Ownership

• Own the end-to-end architecture of a high-performance trading platform.
• Design systems for ultra-low latency, high transactions per second (TPS) and predictable performance.
• Architect scalable, fault-tolerant distributed systems with zero-downtime principles.
• Drive active-active, multi-region architecture strategy and disaster recovery readiness.

Performance, Reliability & Engineering Excellence

• Lead performance benchmarking, tuning and capacity planning.
• Establish architectural governance and engineering best practices.
• Lead architecture reviews and contribute to large-scale architecture revamps.
• Mentor senior engineers and provide technical direction across teams.

Capital Markets & Broking Domain

• Bring a strong understanding of the complete order lifecycle in broking, including validation, risk checks, routing, exchange acknowledgement, trade confirmation and settlement.
• Design ultra-low latency trade routing, deterministic execution flows, order state management, reconciliation and audit trails.
• Understand market feed ingestion, including tick-by-tick data, LTP and market depth, along with high-throughput feed processing, normalization and real-time charting data pipelines.
• Architect real-time portfolio tracking, position management, MTM and P&L computation, pre- and post-trade risk validation, margin and exposure management.
• Design data movement and event propagation across OMS, RMS, portfolio, reporting and notification services, with appropriate consistency and inter-service communication patterns.

Security, Compliance & Governance

• Work with an understanding of broking technology compliance requirements.
• Ensure appropriate data encryption in transit and at rest, and secure key management practices.
• Define data retention, archival and backup strategies.
• Build disaster recovery and audit-readiness considerations into platform architecture.

Cloud, Infrastructure & Technology

• Design services hosted on AWS and/or GCP, including multi-AZ and multi-region deployment architectures.
• Drive active-active setup, high-throughput regional design and disaster recovery architecture, including RTO/RPO planning.
• Apply strong fundamentals in concurrency, distributed systems and networking.
• Build event-driven systems using Kafka, with asynchronous processing and high-throughput event pipelines.
• Use gRPC for public APIs and inter-service communication.
• Bring exposure to containerization and orchestration.

Candidate Requirements

• 15+ years of experience in backend and distributed systems engineering.
• Mandatory 3–5 years of experience in stock broking, trading platforms or capital markets.
• Proven experience building ultra-low latency, high-scale systems and handling mission-critical platforms with strict SLAs.
• Strong proficiency in both Go and Java.
• Deep understanding of concurrency, distributed systems, networking fundamentals, data consistency models and service decomposition.
• Hands-on experience with gRPC and Kafka, including asynchronous processing and high-throughput event pipelines.
• Experience hosting services on AWS and/or GCP, with exposure to multi-AZ, multi-region, active-active and disaster recovery architectures.
• Strong architectural ownership, technical decision-making and leadership experience.

What Success Looks Like

• A scalable, high-performance trading platform that delivers predictable performance during peak market volatility.
• Reliable, fault-tolerant architecture with strong availability, active-active capabilities and disaster recovery readiness.
• Efficient order, market data, portfolio and risk workflows supported by robust distributed-system design.
• Strong architectural governance, engineering practices and technical alignment across teams.
• Secure, compliant and audit-ready technology foundations for a mission-critical broking platform.
