We have an opportunity to impact your career and provide an adventure where you can push the limits of what is possible.

As a Lead Software Engineer at JPMorganChase within the Client On-boarding & Integration Specialist team, you will join our Equities Electronic Trading technology team - a highly-skilled, business-aligned group of technologists responsible for building and operating JPMorgan's cutting-edge Ultra Low Latency Trading platform. The platform provides services spanning exchange and client connectivity, DMA, risk checking, order management, RFQ, IOI, contribution, market data, and trade capture.

This is a senior, hybrid role bridging client-facing FIX on-boarding with integration / DevOps responsibilities for the underlying trading platform. As a VP you will own the end-to-end on-boarding experience for new clients and partners - from FIX session design and configuration, through environment build-out and certification, to production cut-over and ongoing support - while also leading and mentoring on the broader engineering, release, and resiliency agenda. You will partner directly with Sales, Electronic Client Solutions, and Trading desks, and represent the platform to external clients, brokers, and vendors.

The successful candidate must be comfortable operating as a front-office specialist in a high-pressure, fast-paced environment, where time-to-market is critical but never at the expense of quality, stability, or performance.

Job responsibilities

• Lead the on-boarding process for new clients and partners on to our equities electronic trading systems, ensuring a seamless integration with our DMA, OMS, and risk infrastructure.
• Serve as the primary technical point of contact and trusted advisor for clients during on-boarding, providing hands-on guidance and senior-level escalation support.
• Configure, certify, and test FIX connections (and other financial messaging protocols) end-to-end to ensure they meet client specifications, internal standards, and industry conformance requirements.
• Build and maintain network connectivity and FIX session connectivity between internal applications and external clients / business partners; liaise with network, infrastructure, and counterparty technical teams.
• Troubleshoot and resolve complex technical issues that arise during on-boarding and early production life, owning resolution to closure.
• Develop and maintain comprehensive documentation for each client on-boarding project - specifications, FIX rules of engagement, design documents, and run-books.
• Provide training and ongoing support to clients on the use of our trading systems and FIX interfaces.
• Continuously improve the on-boarding process by identifying gaps, automating repeatable steps, and embedding best practices across the team.
• Mentor and coach junior on-boarding engineers and act as a subject-matter expert for the wider organisation.
• Build out and enhance development, UAT, and certification environments used for client integration and platform development.
• Drive ITSM and release management - integrating client and platform changes into release tickets, coordinating cut-overs, and communicating with stakeholders across regions.
• Contribute to resiliency design and setup, including persistence replication, fail-over, and DR / HA architecture.
• Design and implement test automation for FIX certification, regression, and platform validation.
• Lead or contribute to cyber-security and stability initiatives across the trading stack.
• Share responsibility for Dev, UAT, and Production support with teammates, including participation in on-call rotations where required.
• Work across the entire software development lifecycle for platform deliveries - requirements gathering, design, implementation, testing, deployment, and hand-over to operate teams.
• Stay current with industry trends and developments in FIX, electronic trading, and exchange connectivity, and feed those back into the platform roadmap.

Required qualifications, capabilities, and skills

• Minimum of 10 years experience in a FIX on-boarding, client integration, or closely related role within the financial services industry - ideally in equities electronic trading / DMA - with a clear track record of operating at a senior / VP-equivalent level.
• Strong, hands-on understanding of the FIX protocol and electronic trading systems; ability to read FIX logs, debug session and application-level issues, and reason about rules of engagement.
• Proven track record of successfully on-boarding clients end-to-end in a front-office environment, including managing complex, multi-stakeholder integrations.
• Solid understanding of computer-science fundamentals and experience in real-time, high-performance, and/or e-trading systems.
• Proficiency in a scripting language such as Python or Perl for automation, certification, and testing.
• Good knowledge of Unix / Linux commands and shell scripting.
• Familiarity with network protocols, connectivity (TCP, multicast, cross-connects, extranets), and security practices.
• Excellent problem-solving skills, attention to detail, and the ability to manage multiple client and platform projects simultaneously under tight deadlines.
• Excellent verbal and written communication skills, with the ability to engage credibly with clients, sales, trading, and senior internal technology stakeholders.
• Creative, analytical, quick-thinking, pragmatic, with an aptitude for solving problems with technology.
• Demonstrated experience mentoring junior engineers and contributing to team culture.

• Degree-level qualification in Computer Science, Mathematics, Physics, Engineering, or a related discipline.
• Programming experience in C / C++ / Java is a strong plus.
• Experience building and supporting high-performance and resilient applications in a real-time / low-latency environment.
• Experience working in a team with a strong software development process (build, test, deploy) and modern toolchain (Git, Jira, Confluence, CI/CD).
• Experience with test automation frameworks and FIX certification tools.
• Exposure to exchange connectivity, DMA, smart order routing, or risk-checking platforms.
• Certification in FIX protocol or related areas is a plus.
