Jobtailor; Kentucky; On-site; USD 140,000 - 190,000; Full time

Job summary

Fidelity is seeking a senior platform engineer to design, deploy, and operate large-scale Kubernetes clusters and cloud-native infrastructure. You will own self-service developer platforms and golden-path templates while collaborating with Fidelity’s Enterprise Technology Platform Engineering team.

The role emphasizes strong Java/Spring Boot microservices, CI/CD maturity, and hands-on experience with cloud platforms and observability tooling.

Qualifications

• Bachelor or Master Degree in a technology-related field (e.g. Engineering, Computer Science, etc.).
• 5+ years of hands‑on experience designing, deploying, and operating production Kubernetes clusters (self‑managed or managed services such as EKS, AKS, GKE).
• Deep expertise in Kubernetes internals: workload scheduling, RBAC, network policies, Helm / Kustomize, Operators, and cluster autoscaling.
• Must have 3+ years of experience developing microservices with Java and Spring Boot.
• Strong understanding of microservices architecture, REST APIs, and event‑driven design patterns.
• Experience containerizing and deploying Java applications to Kubernetes, including JVM tuning for container environments.
• Familiarity with build tooling (Maven, Gradle) and code quality practices (unit/integration testing, static analysis).
• Strong experience with DevOps practices and tooling: CI/CD pipelines (Jenkins, GitHub Actions, ArgoCD / Flux GitOps), Infrastructure as Code / IAC (Terraform or CloudFormation, Ansible), and container image management (Docker, container registries).
• Proven ability to build and maintain self‑service developer platforms and golden‑path templates on Kubernetes.
• 2+ years of experience operating workloads on Cloud platforms (AWS, Azure, or GCP), including networking, IAM, and cost optimization.
• Strong knowledge of observability: metrics (Prometheus/Grafana), logging (ELK / OpenSearch), and distributed tracing.
• Experience with service mesh technologies (Istio, Linkerd) and API gateway patterns.
• Solid experience in Agile methodologies (Kanban and SCRUM).
• Strong technical design and analysis skills; ability to deal with ambiguity and work in a fast‑paced environment.
• Excellent communication skills, both written and verbal, with strong collaboration skills across multiple teams.

Responsibilities

• Build, automate, and operate large-scale event-driven platforms.
• Apply a variety of technologies to deliver robust, self-service infrastructure and deployment pipelines.
• Collaborate with the Platform Engineering group within Fidelity’s Enterprise Technology organization.
• Design and operate large-scale, cloud-native infrastructure using cutting-edge technologies.
