Job Description
Wells Fargo is seeking a Full Stack Developer to join our Platform Engineering team and help build a modern, self-service, GitOps-driven Internal Developer Platform (IDP). This role is ideal for a developer who understands the toil of infrastructure and is passionate about removing barriers for fellow engineers.
You'll work across the stack to design and deliver API-first platform services, microservice-based abstractions, and intuitive developer-facing interfaces that simplify infrastructure complexity and accelerate application delivery across hybrid cloud environments.
**In this role, you will:**
+ Build and maintain full-stack components of our Internal Developer Portal, including service catalogs, golden paths, and CI/CD templates.
+ Design and implement API-first platform services and reusable microservice components.
+ Contribute to the creation of a unified control plane that abstracts hybrid cloud complexity and enables seamless application mobility.
+ Develop self-service automation workflows that enable developers to provision infrastructure, deploy applications, and monitor services independently.
+ Integrate with tools like Backstage, ArgoCD, Terraform, and Kubernetes to deliver a seamless developer experience.
+ Write clean, maintainable code and participate in code reviews and architecture discussions.
+ Collaborate with platform, security, and application teams to align platform capabilities with developer needs.
**Required Qualifications:**
+ Experience in Engineering, or equivalent demonstrated through one or a combination of the following: work experience, training, military experience, education.
**Desired Qualifications:**
+ Proficiency in Python, Go, TypeScript, or Java.
+ Experience building and consuming RESTful APIs and working with microservice architectures.
+ Familiarity with developer portals (e.g., Backstage, Port, Cortex) and CI/CD pipelines.
+ Hands-on experience with infrastructure-as-code tools like Terraform, and GitOps tools like ArgoCD or Flux.
+ Knowledge of Kubernetes, Docker, and hybrid cloud platforms (Azure, GCP, or AWS).
+ Understanding of observability tooling (e.g., Prometheus, Grafana, ELK Stack).
+ A developer-first mindset with a passion for improving the developer experience.
+ Experience with service mesh technologies (e.g., Istio, Linkerd).
+ Familiarity with API management tools like Kong or Apigee.
+ Exposure to image management tools like Packer or Image Builder.
+ Background in building tools that support cloud-native development and service ownership.
