Senior Lead Infrastructure Engineer - Network Engineering

As As a Lead Infrastructure Engineer within the Electronic Trading Service at JPMorgan Chase, you bring broad, cross-disciplinary expertise spanning low-latency software, network/platform engineering, and the end-to-end electronic trading stack across Investment Banking Markets (FICC and Equities). You pair deep domain knowledge of trading verticals and high-level execution strategies (e.g., agency execution, market making, hedging, and liquidity-seeking/impact-minimizing routing) with a strong understanding of core market components—including real-time market data (L1/L2, multicast feed-handling, normalization and distribution), venue connectivity, and exchange/order semantics (order types, time-in-force, throttles/limits, and drop-copy/clearing flows). The successful candidate will have hands-on experience using IXIA to validate performance and traffic behaviour under realistic market-data and order-entry patterns—characterizing throughput, latency, jitter, microburst behaviour, and packet loss—and will hold an active network platform certification (e.g., Cisco, Juniper, Arista, or equivalent). Job responsibilities Develop and design the architecture for electronic trading systems, ensuring scalability, reliability, and performance to meet trading requirements. Applies deep technical expertise and problem-solving methodologies focused on analyzing complex data and systems, anticipating issues, and finding ways to mitigate risk. Works with other platforms to architect and implement changes required to resolve issues and modernize the organization and its technology processes Maintain detailed documentation of system architecture, configurations, and changes, and provide regular reports on system performance and issues. Acts as the escalation point during major incidents for your application and demonstrates the skills to identify and solve issues quickly to avoid financial losses. Be responsible for infrastructure engineering in accordance with business requirements. Executes work according to compliance standards, risk and security, and business objectives Considers upstream/downstream system or technical implications and advises on mitigation actions Advises junior engineers and technologists Adds to team culture of diversity, opportunity, inclusion, and respect Required qualifications, capabilities, and skills Bachelor’s Degree in Computer Science or equivalent Formal Training and certification such as CCNP, CCIE or equivalent and 5+ years of applied experience Strong understanding of network architecture, protocols, and technologies (e.g., TCP/IP, multicast, routing, switching). Knowledge of one or more areas of infrastructure engineering such as hardware, networking terminology, databases, storage engineering, deployment practices, integration, automation, scaling, resilience, or performance assessments Experience in network architecture, systems engineering, or a related field, within the financial services industry. Utilize network automation tools and scripting languages (e.g., Python, Ansible) to automate network tasks and configurations. Deep technical knowledge across multiple domains including Cloud technologies. Design, configure, and manage routing, switching infrastructure including load balancers, to ensure efficient distribution of network traffic. Ability to adapt to a fast-paced and dynamic trading environment, with a willingness to learn and implement new technologies. Maintain a thorough understanding of basic and advanced concepts in the fields/products/tools of: Network system architecture (processor, ASIC, FPGA, port capabilities, packet forwarding, buffers, etc.); a good knowledge of network routing protocols: Multicast, PIM & IGMP; IP packet analysis using Wireshark; Arista, Cisco, F5 and Fortinet product range. Preferred qualifications, capabilities, and skills Exposure to managing budgets Familiarity with financial markets, trading platforms, and electronic trading systems. Understanding of market data feeds and exchange connectivity Understand deeply network design, implementation, and maintenance, and manage complex network environments to ensure the reliability, performance, and security of the trading infrastructure. Configure and manage Cisco routers and switches with proficiency, including knowledge of IOS and NX-OS. Demonstrate expertise in Arista's EOS and experience with Arista's low latency switching solutions. Comprehend in-depth network protocols such as BGP, FHRP, and multicast.
