Position Overview

We are seeking a highly skilled and experienced Senior Infrastructure & Specialist to join our India Equities Technology team.

The ideal candidate will possess a strong background in capital markets, hands-on expertise in Linux/Unix environments, deep knowledge of the FIX protocol, and a proven track record of supporting high-touch trading desks, Direct Market Access (DMA), and algorithmic trading platforms. You will bridge the gap between infrastructure operations, development teams, and business stakeholders to maintain a seamless trading environment.

Key Responsibilities

1. Infrastructure & Environment Management

  • Environment Maintenance: Manage and maintain multi-tier UAT and Production environments, ensuring system stability, configuration consistency, and readiness for daily trading activities.
  • Batch Scheduling & Automation: Design, configure, monitor, and troubleshoot batch jobs using Autosys to automate critical operational workflows and data processing.
  • System Operations: Perform daily Start of Day (SOD) and End of Day (EOD) activities on Linux systems to guarantee environment availability for live trading.
  • Database Support: Query and manage relational databases (SQL, Postgres, Oracle) to fetch data, analyze table partitions, and support data warehousing requirements.

2. Application & Connectivity Support

  • FIX Connectivity Management: Lead the functional enhancement, configuration, and monitoring of the FIX connectivity platform. Manage client onboarding, UAT testing, and certification of FIX algos.
  • Trading Desk Support: Provide on-floor L1/L2 production support to high-touch trading desks for equities, futures, and options, as well as DMA and algorithmic trading desks.
  • Exchange Connectivity: Coordinate and execute exchange connectivity tasks, including uploading exchange files, margin/position files, and participating in regular exchange mock trading sessions (e.g., NSE/BSE).
  • Vendor & Developer Collaboration: Act as the primary technical liaison with third-party application vendors (e.g., Omnesys, Traderpath) and internal development teams to resolve complex application bugs and deploy backend fixes.

3. Monitoring, Incident & Change Management

  • Proactive Monitoring: Utilize enterprise monitoring tools such as ITRS Geneos to track system health, latency, and connectivity, proactively addressing alerts before they impact the business.
  • Incident Resolution: Own and manage production incidents from detection through to resolution. Perform root cause analysis (RCA) and raise/track tickets in ServiceNow and Jira.
  • Change & Release Management: Schedule, coordinate, and deploy production changes, software packages, and drivers on servers during non-market hours, adhering to strict change control policies.
  • Regulatory Reporting: Ensure timely processing and transfer of operational and transaction files (e.g., OTR files) to regulatory bodies (e.g., SEBI) and clients.

Required Technical Skills & Qualifications

Experience & Education

  • Experience: Minimum of 7+ years of experience in production support, application support, or infrastructure operations within the Capital Markets / Investment Banking domain.
  • Education: Bachelor’s degree in Engineering (Electronics & Telecommunications, Computer Science, or a related technical field).

Technical Competencies

  • Operating Systems: Strong administration and troubleshooting skills in Linux/Unix and Windows environments.
  • Scripting: Proficiency in Unix Shell Scripting for task automation, log analysis, and data extraction.
  • Protocols: Deep understanding of FIX Protocols (session and application levels) and FIX configuration.
  • Databases: Solid experience writing SQL queries and working with Postgres, Oracle, or SQL Server.
  • Tools & Applications:
    • Scheduling: Autosys
    • Monitoring: ITRS Geneos
    • Ticketing/Collaboration: ServiceNow, Jira

Soft Skills & Domain Knowledge

  • Domain Expertise: Comprehensive understanding of capital markets, equity/derivatives trading lifecycles, and high-frequency trading (HFT) concepts.
  • Stakeholder Management: Ability to collaborate effectively with diverse stakeholders, including Institutional Sales, Execution Traders, QA, Compliance, and external vendors.
  • Problem-Solving: Exceptional analytical skills with the ability to perform under pressure during live market hours.
