Job description

Are you a software engineer who thrives at the intersection of technical delivery and application ownership? At JPMorganChase, we build technology that powers one of the world's most trusted financial institutions — and we're looking for engineers who take pride in both the quality of their code and the integrity of the systems they own. This is your opportunity to make a lasting impact on critical infrastructure platforms while growing your career in a firm that invests in its people.

As a Lead Software Engineer at JPMorganChase within the Infrastructure Platforms, Data Center Services team, you are an integral part of an agile team that works to enhance, build, and deliver trusted market-leading technology products in a secure, stable, and scalable way. In this combined role, you take end-to-end ownership of technical delivery while also serving as the Application Owner for one or more applications within the Data Center Services portfolio — accountable for their lifecycle management, risk posture, resiliency, and compliance with firmwide standards. This role is ideal for a self-starter who thrives in a collaborative environment, can manage competing priorities, and drives engineering excellence across the team.

Job responsibilities

• Design, develop, and deliver full stack software solutions across frontend (Angular) and backend (Node.js/TypeScript) services, applying strong problem-solving skills to break down complex technical challenges.
• Develop secure, high-quality production code and review peers work to maintain consistency, reliability, and adherence to engineering standards.
• Leverage AI-assisted development tools (e.g., GitHub Copilot, AI code review assistants) to improve productivity, code quality, and delivery speed, and champion their effective adoption within the team.
• Mentor and support junior engineers, providing technical guidance and fostering a culture of continuous improvement and engineering excellence.
  Identify opportunities to eliminate or automate remediation of recurring issues to improve the overall operational stability of applications and systems.
• Own and maintain the application profile and registration in SOR, ensuring all application metadata, data classifications, and information flows are accurate, current, and compliant with firmwide governance requirements.
• Partner with Risk and Technology Risk and Controls (TRC) teams to assess application risk, implement required controls, and proactively manage compliance breaks and control gaps.
• Manage application lifecycle activities including DR test coordination, tech refresh planning, demand and capacity management, and maintenance.
• Ensure the application meets all SDLC governance, operational hygiene, and compliance requirements including the Technology Risk and Controls Catalog and relevant regulatory standards.
• Maintain and continuously improve application security posture, including cloud security responsibilities such as data protection, application security, encryption, environment segregation, monitoring, and resiliency requirements.
• Partner with Product Manager to align application uplift with future sprint planning.
• Participate in communities of practice across Software Engineering to drive awareness and adoption of modern tooling, patterns, and best practices
  

Required qualifications, capabilities, and skills

• Formal training or certification on software engineering concepts and advanced applied experience
• Hands-on practical experience across the full Software Development Life Cycle, including system design, application development, testing, continuous integration/continuous delivery pipelines, and operational support
