Responsibilities

Platform Engineering (Core)

• Build and evolve an internal developer platform (IDP) based on GitOps and Kubernetes;
• Design and deliver self-service infrastructure capabilities for product teams;
• Treat the platform as a product - developer experience is your primary metric;
• Contribute to IDP evolution using tools such as Crossplane, GitOps, and internal APIs;
• Maintain and extend Infrastructure as Code (Terraform / OpenTofu);
• Deliver prototypes that evolve into production platform capabilities.

AI & Agentic Engineering

• Use AI coding assistants daily (Claude, Copilot, or equivalent);
• Design agentic workflows to automate platform operations (debugging, remediation, documentation, scaffolding);
• Build AI-augmented tooling into the platform where it improves developer velocity;
• Define and raise the standard for responsible AI usage in engineering.

Cloud, AWS & Networking

• Operate AWS services (EKS, IAM, S3, RDS, Lambda, CloudWatch);
• Design and troubleshoot VPC architectures, routing, and multi-account networking;
• Work confidently with:
  • CIDR planning, subnets, route tables;
  • Security groups, NACLs;
  • Transit Gateway, VPC peering;
  • Private connectivity via VPC endpoints;
  • DNS (Route53);
  • Debug Kubernetes networking (Ingress, Services, CNI, Network Policies).

GitOps & Kubernetes

• Operate Argo CD as a core delivery platform;
• Own multi-environment deployment strategies using ApplicationSets;
• Support progressive delivery (blue/green, canary where applicable);
• Deploy, troubleshoot, and instrument Kubernetes workloads.

GitHub Platform Ownership

• Manage GitHub organization as a platform product:
  • Organization structure, teams, repositories, templates;
  • Branch protection, environments, review policies;
  • Build reusable GitHub Actions workflows for platform-wide consumption;
  • Operate CI automation (PR checks, labeling, merge automation);
  • Define Copilot governance and AI usage standards across repositories;
  • Ensure secure OIDC integration between GitHub and AWS.

Artifact Management

• Operate JFrog Artifactory (or equivalent systems at scale);
• Manage registries (containers, Helm, language packages);
• Define promotion flows across environments;
• Implement artifact security scanning, retention, and signing policies.

Collaboration & Leadership

• Work cross-functionally with CloudOps, DevSecOps, FinOps, and SRE;
• Mentor engineers and contribute to technical direction;
• Drive adoption of platform standards across teams;
• Lead delivery of prototypes and platform capabilities;
• Communicate clearly and influence across engineering domains.

Requirements

• 7+ years in Platform Engineering, SRE, or closely related roles;
• Strong platform mindset (you build systems, not ticket queues);
• Deep AWS experience (EKS, IAM, networking, core services);
• Strong Kubernetes operational experience;
• Hands-on Argo CD / GitOps experience;
• Infrastructure as Code: Terraform / OpenTofu;
• CI/CD pipeline design experience (tool-agnostic);
• GitHub administration at scale (organizations, workflows, governance);
• Experience with artifact management systems (JFrog or equivalent);
• Strong scripting skills (Python, Go, Bash, etc.);
• Proven ability to work across teams and deliver outcomes.
