This is a hands‑on engineering leadership role involving platform architecture, critical system development and team leadership. The individual will drive platform performance, optimise latency, ensure reliability during live markets and build robust trading infrastructure.

Key Responsibilities

• Own the architecture and technical direction of the trading platform, covering market data, signals, execution and risk systems.
• Design and develop critical, latency-sensitive components.
• Optimise tick-to-trade latency across market data ingestion and order execution.
• Build and maintain real‑time, event‑driven trading systems.
• Implement robust pre‑trade and at‑trade risk controls.
• Ensure platform reliability, high availability, fault tolerance and production monitoring.
• Lead and mentor the engineering team while maintaining hands‑on technical involvement.
• Manage integrations with exchanges, brokers, market‑data providers and OMS platforms.
• Oversee connectivity, colocation, disaster recovery, redundancy and failover infrastructure.
• Establish testing, deployment, security and governance practices, ensuring alignment with SEBI and exchange requirements.

Required Skills & Experience

• 10+ years building and operating production‑grade backend systems, with experience leading engineers or owning technical direction.
• Expert Python programming skills with strong knowledge of asyncio, concurrency and asynchronous architectures.
• Experience building real‑time, event‑driven systems handling live market data and order‑event streams.
• Hands‑on experience integrating with exchanges, OMS platforms, brokers and external trading infrastructure.
• Strong understanding of MongoDB, Redis and time‑series/columnar databases such as ClickHouse.
• Experience designing highly available, scalable and observable production systems.
• Hands‑on experience with Docker, CI/CD and automated deployments.
• Understanding of Indian market infrastructure, including NSE, BSE, MCX, exchange connectivity, colocation and OMS platforms such as XTS, Greeksoft or ODIN.
• Familiarity with SEBI technology, cybersecurity, disaster recovery and business continuity requirements.

Good to Have

• Experience building high‑frequency or ultra‑low‑latency trading systems.
• Exposure to tick‑by‑tick market data feeds and colocation environments.
• Experience with DPDK, Solarflare/Onload, FPGA or kernel‑by‑pass networking.
• Knowledge of low‑level performance optimisation and C/C++/Rust.

All applications and conversations will be handled with complete discretion.
