Job description

Required qualifications, capabilities, and skills

• Backend engineering: Proficiency in one or more backend languages Python, Golang, or Java.
• Schema-driven experiences: Experience building dynamic, schema-driven UIs and services from structured contracts such as the OpenAPI Specification (OAS) or JSON Schema.
• API gateway configuration: Professional experience configuring API gateways - Kong, Envoy, Akamai/CloudFront including routes, services, upstreams, and plugins.
• GitOps model: Hands‑on experience with GitOps‑based delivery - author intent → PR → validate → merge → reconcile — with automated rollback on failure.
• CLI & code‑editor tooling: Comfort with CLI‑driven and code‑editor‑based workflows for gateway onboarding - authoring, validating, and committing configuration directly as code.

• Kong: Deep, hands‑on experience with Kong API Gateway (plugins, consumers, upstreams, schema validation).
• Envoy: Hands‑on experience with Envoy Proxy or Envoy Gateway (routes, filters, and configuration).
• Akamai / CloudFront: Familiarity with edge configuration (CDN, WAF, GTM, certificates, property versioning/activation).
• Config reconciliation & drift: Experience building drift detection and desired‑state reconciliation between Git and live systems.
