Principal Trading Infrastructure Architect

# Principal Trading Infrastructure Architect

## Company Overview

*Not specified.*

## Job Summary

We are seeking a Principal Trading Infrastructure Architect to lead the design and development of our next-generation ultra-low latency, highly scalable, and deterministic trading platform. This leadership role involves defining the overall technology stack, establishing architectural standards, and guiding engineering teams to build world-class trading infrastructure tailored for Indian equity, F&O, and commodity markets. The successful candidate will own the end-to-end architecture of exchange connectivity, market data processing, order routing, risk engines, and core trading middleware, with a focus on achieving microsecond and nanosecond efficiencies.

## Responsibilities

• Architecture & Core Infrastructure Design
• Design, architect, and deliver foundational core engine components, including high-throughput Market Data Feed Handlers, Order Management Systems (OMS), Execution Management Systems (EMS), and pre-trade Risk Checkers.
• Develop event-driven, microsecond-deterministic middleware capable of handling multi-venue connectivity, state recovery, and high-frequency order flows with zero runtime memory allocations.
• Create low-latency exchange interfaces tailored to local exchange feed formats and binary execution protocols across Indian liquidity venues.
• Drive hardware-software co-design strategies, including CPU core affinity pinning, Non-Uniform Memory Access (NUMA) balancing, network card acceleration, and kernel bypass integration.
• Technical Leadership & Standards
• Establish company-wide technical standards, design patterns, coding guidelines, and low-latency architectural principles.
• Evaluate, benchmark, and select the optimal technology stack, compiler setups, profiling tools, and operating environments for deterministic execution.
• Lead code reviews, enforce strict zero-overhead abstraction patterns, and mentor engineers in writing production-grade low-latency systems.
• Measurement, Benchmarking & Optimization
• Build nanosecond-accurate latency tracking, telemetry, and micro-benchmarking frameworks to continuously monitor tick-to-trade latencies.
• Optimize memory layout, cache usage (L1/L2/L3), data structures, and concurrency pipelines to eliminate lock contention, OS context switches, and jitter.
• Implement robust disaster recovery, high availability, and state synchronization frameworks without degrading processing speed.

## Qualifications

• Technical Expertise
• 8+ years of hands-on experience designing low-latency, high-frequency, or mission-critical real-time systems.
• Deep domain knowledge of Indian financial exchanges (NSE, BSE, MCX) and their specific feed and protocol structures (e.g., NSE TBT, NNF, FIX, FAST, OUCH/ITCH).
• Proficiency in low-level systems programming, lock-free/wait-free data structures, manual memory management, zero-copy networking, and cache optimization techniques.
• Extensive experience with Linux kernel tuning, network bypass mechanisms (e.g., user-space network stacks, hardware acceleration cards), IPC mechanisms, and TCP/UDP multicast optimization.
• Proven track record of building exchange adapters, order books, and real-time pre-trade risk engines for tick-to-trade pipelines.
• Educational Qualifications
• Not explicitly specified, but typically a Bachelor’s or Master’s degree in Computer Science, Engineering, or related fields.

## Preferred Skills

• Prior experience as a Lead or Principal Systems Architect at top HFT firms, quantitative market-making houses, or high-performance brokerage technology providers, especially in India or globally.
• Working knowledge of co-location facilities (e.g., NSE co-location at BKC/GIFT City), network switches, and hardware offloading concepts such as SmartNICs or FPGAs.

## Experience

• Minimum of 8+ years of relevant experience in designing and implementing low-latency, high-frequency trading systems or mission-critical real-time systems.
• Experience working with Indian financial exchange protocols and infrastructure is highly desirable.

## Environment

• The role involves working in a high-performance, technology-driven environment focused on ultra-low latency trading systems.
• Location details are not specified; the role may involve in-office, remote, or hybrid work depending on company policies.
• The work requires deep technical focus, collaboration with cross-functional teams, and engagement with hardware and network infrastructure.
