• Develop and maintain scalable, reliable automation and integrations across AWS, GCP, and Azure, SaaS platforms, and custom services (including APIs and event-driven workflows). • Design, implement, and operate CI/CD using Jenkins, Dagger, Terraform, and Docker, with repeatable pipelines for applications and platform components. • Work in a Git-centric workflow (branching, reviews, collaboration) and contribute to infrastructure-as-code and GitOps delivery models. • Build, operate, and troubleshoot workloads on Kubernetes, using Kustomize and Helm, and platform tooling such as Argo CD, Argo Workflows, Argo Events, Argo Rollouts, Crossplane, and related controllers (External Secrets, Sealed Secrets, cert-manager, ingress such as Traefik, AWS Load Balancer Controller, External DNS) as appropriate to the environment. • Support configuration management and fleet-style operations with Ansible where applicable, alongside cloud APIs and automation. • Develop and maintain REST (and SOAP where legacy systems require) APIs and integrations between services, data stores, and identity systems. • Program in Python, Go, and TypeScript/JavaScript (Node.js) (and other languages as needed) for tooling, integrations, and platform automation. • Apply Agile practices to prioritize work, collaborate with stakeholders, and deliver incremental value with clear operational outcomes. • Design and operate event-driven patterns using managed services (e.g. Lambda, SQS, SNS, API Gateway) and/or Kubernetes-native and workflow platforms (Knative, workflow engines, integration with n8n or similar) to improve responsiveness and scale. • Contribute to observability and reliability: metrics, logs, and tracing aligned with stacks such as Prometheus, Grafana, and Grafana Alloy (or equivalent), and operational dashboards for platform health. • Where relevant, support developer portal and platform engineering initiatives (e.g. Backstage-style experiences), container registries (Harbor, artifact stores), and safe promotion patterns across environments.

• Learn the infrastructure, ship confidently • Ship a small infrastructure improvement: Terraform module refactor, monitoring enhancement, or CI/CD optimization • Strengthen system reliability with better metrics, alerts, autoscaling policies, and failure recovery mechanisms • Lead a platform-wide initiative: single immutable image pipeline, infrastructure standardization, database performance optimization, or security hardening • Partner with engineering, security, and compliance teams to make pragmatic tradeoffs on reliability, cost, and regulatory requirements
