Staff Infrastructure Engineer

The Staff Infrastructure Engineer owns the design, operation, and maturity of FanDuel's Kubernetes platforms and service mesh ecosystem, which includes 100+ Kubernetes clusters across AWS Cloud and Outposts. The role sits alongside the Infrastructure Engineering Director to set standards for Kubernetes operations and service-to-service communication, and includes mentoring engineers on cluster and mesh internals. It leads incident response when Kubernetes or mesh issues impact services, builds automation to reduce toil, and helps teams adopt patterns that work reliably at scale.

• Design and operate the Kubernetes platform across EKS clusters, setting standards for cluster configuration, workload isolation, resource management, and cost optimization, and building runbooks and automation that make operations predictable.
• Own the Kong Mesh ecosystem and mature it from a deployment into a production-grade platform with clear patterns for service-to-service security, traffic management, and observability.
• Define and implement service-to-service communication patterns, working with teams on zero-trust networking, certificate lifecycle, mTLS policies, and debugging.
• Build infrastructure-as-code, automation, and tooling that reduce toil and enable teams to operate reliably.
• Define quality standards for the infrastructure platform, set SLOs, monitor reliability, and hold the line on quality.
• Lead incident response when Kubernetes or mesh issues impact services, understand root cause, fix it, and prevent the same failure from happening twice.
• Mentor engineers on Kubernetes internals, mesh design, and distributed systems thinking to raise technical understanding across the team.
• Evaluate infrastructure tools and platforms to determine what to build, buy, or integrate.
• Work with platform and product teams to understand their Kubernetes and mesh needs and feed those into the roadmap and direction.
• Contribute to broader infrastructure initiatives on observability, cost optimization, and resilience, owning technical scope on assigned work.

• 7+ years of experience working with platform infrastructure, SRE, cloud infrastructure, or related work, including building and operating large systems and shipping real things.
• Deep hands-on experience with Kubernetes, including cluster architecture, multi-cluster operations, scheduling, networking, security, and debugging.
• Strong expertise with modern service mesh platforms, such as Kong Mesh, Istio, Linkerd, or Envoy-based systems, including mTLS, traffic policies, and zero-trust networking.
• Working knowledge of AWS, including VPCs, networking, security, and operating in hybrid environments such as AWS Outposts.
• Understanding of distributed systems and the tradeoffs involved in service-to-service communication at scale, with attention to failure modes.
• Experience defining and tracking SLOs/SLIs for infrastructure services, using metrics that matter to users and the business.
• Ability to code in at least one modern language, build tools and automation, and operate systems as well as write code.
• Experience driving operational improvements through automation, reducing toil, and preventing the same failure from happening twice.
• Experience mentoring and influencing other engineers and raising the technical bar.
• Strong communication skills, including explaining technical constraints to non-technical audiences and influencing technical direction.
• Ownership of problems end-to-end and a commitment to continuous improvement.

• Experience using Envoy in production.
• Experience operating AWS Outposts or hybrid cloud infrastructure.
• CNCF Kubernetes certifications (CKA, CKS, CKAD).
• Experience in regulated industries where network segmentation, auditability, strict controls, and uptime matter.
• Familiarity with Datadog or other observability platforms and eBPF-based networking tools like Cilium.

• A range of health plans to choose from, some as low as $0 per paycheck, including fertility and family planning programs, mental health support, and fitness benefits.
• Generous paid time off, including PTO and sick leave, plus paid personal time off and 14 paid company holidays.
• Medical, vision, and dental insurance; life insurance; disability insurance; and a 401(k) matching program.
• Annual bonus and long-term incentive opportunities based on performance, as well as short-term or long-term incentive compensation including cash bonuses and stock program participation.
• 401(k) with up to a 5% match.
• Commuter benefits and pet insurance.
• Paid sick time in accordance with all applicable state and federal laws.
• Benefits may differ across location, role, and level.
