JPMorganChase · United States
Join JPMorganChase as a Lead Infrastructure Engineer to design, operate, and continuously improve enterprise DNS and IPv6 capabilities with a focus on reliability, security, and measurable service outcomes. You will partner with infrastructure, application, and operations teams to deliver scalable network design, accurate name resolution, and strong diagnostics practices in a diverse, inclusive environment.
About the Role
As a Lead Infrastructure Engineer within JPMorganChase’s Enterprise Technology, network services team, you will play a pivotal role in shaping the future of global infrastructure. You will design enterprise DNS architectures and standards that support resilient, scalable name resolution across hybrid environments, while engineering IPv6 addressing plans and network designs using 128-bit formats, subnetting, and architecture patterns. You will operate core DNS services with an availability-first mindset, troubleshoot complex DNS and connectivity issues, and automate repeatable operational tasks to reduce manual effort and improve consistency. This role is ideal for a senior infrastructure engineer who thrives in a high-performance, diverse, and inclusive environment and is passionate about building scalable, secure, and reliable network infrastructure. You will also leverage enterprise-authorized AI capabilities to accelerate infrastructure analysis and design documentation, validating outputs and handling operational data according to sensitivity and security requirements.
What You Will Do
Design enterprise DNS architectures and standards that support resilient, scalable name resolution across hybrid environments.
Engineer IPv6 addressing plans and network designs using 128-bit formats, subnetting, and architecture patterns.
Operate core DNS services with an availability-first mindset.
Troubleshoot complex DNS and connectivity issues.
Automate repeatable operational tasks to reduce manual effort and improve consistency.
Leverage enterprise-authorized AI capabilities to accelerate infrastructure analysis and design documentation.
Validate outputs and handle operational data according to sensitivity and security requirements.
Partner with infrastructure, application, and operations teams to deliver scalable network design and strong diagnostics practices.
What We Are Looking For
Formal training or certification on Infrastructure engineering concepts and 5+ years applied experience.
Advanced DNS core competencies, including authoritative and recursive DNS concepts, record types, and operational best practices.
IPv6 addressing & architecture fluency, including 128-bit address formats, subnetting, and network design with Global Unicast and Unique Local addressing.
Reverse DNS delegation knowledge for IPv6 using ip6.arpa zones and nibble-format delegations.
Hands-on experience with IPv6 transition and mitigation mechanisms, including Dual-Stack, NAT64, and DNS64.
Strong networking & diagnostics capability, including practical understanding of TCP/IP layers and how they intersect with DNS behavior.
Working knowledge of routing protocols that interact with DNS reachability and traffic paths, including BGP and OSPFv3.
Proven troubleshooting skills using tools such as dig and nslookup to debug resolution outcomes and validate connectivity across A vs. AAAS records.
Demonstrated experience using enterprise-authorized AI capabilities within the work environment to support infrastructure engineering workflows with strong validation habits and awareness of data sensitivity.
Ability to review and validate AI-assisted recommendations before implementation, escalating when uncertain and ensuring outcomes align to resiliency, security, and auditability expectations.
Experience operating within controlled change environments, including planning, peer review, and documentation expectations.
Nice to Have
Proficiency with logging, telemetry, and visualization tools such as Splunk, SevOne, ThousandEyes, and Grafana.
Strong presentation skills, including the ability to explain DNS/IPv6 concepts and operational risk in a crisp, stakeholder-friendly way.
Experience building operational dashboards and service health indicators to improve transparency and proactive detection.
Demonstrated ability to standardize and simplify complex network/DNS patterns into repeatable reference architectures.
