You'll have the opportunity to build internal developer platforms, golden paths, and self-service capabilities that meaningfully accelerate engineering teams. This is a hands-on, highly technical role where you'll influence platform standards, embed reliability and security into every layer, and work with cutting-edge tooling across DevOps, DevSecOps, and observability. If you're motivated by solving complex infrastructure challenges and creating scalable platforms that empower developers, this role offers both impact and ownership. Essential duties include the following: * Architect and maintain AWS-based infrastructure (ECS, EKS, ECR, VPC, IAM, Lambda, API Gateway, S3, RDS). * Implement Infrastructure as Code (IaC) using AWS CDK (preferred), AWS cloud formation and Terraform for modular, reusable patterns. * Optimize cost, performance, and security across environments. * Orchestrate containers, observability stacks, and scaling strategies across distributed systems to ensure reliability and high availability. * Build and standardize CI/CD pipelines using GitHub Actions, reusable workflows, and deployment strategies. * Integrate GitHub Advanced Security (CodeQL, Secret Scanning, Dependabot) into pipelines for proactive security. * Enable OIDC-based deployments for secure, secretless AWS access. * Drive adoption of internal developer platform (IDP) such as Atlassian Compass (Preferred) or Backstage to enable developer self service, service cataloging, scorecards, and golden paths. * Implement OpenTelemetry for distributed tracing and metrics. * Configure APM monitoring tooling (e.g Datadog ), including dashboards, alerts, and SLOs for application health and performance. * Improve MTTR through automated incident response and runbooks. * Embed security checks in CI/CD pipelines (e.g., SAST, dependency scanning, secret scanning, container image scanning, etc.) to support SOC 2 and PCI compliance * Experience with Policy as Code using OPA (Open Policy Agent) and Conftest to validate IaC templates before deployment will be preferred * Apply AWS Well-Architected Framework principles across all platform designs to ensure security, reliability, performance efficiency, cost optimization, and operational excellence. * SBOM (Software Bill of Materials): Ensures transparency of all dependencies for compliance and vulnerability management. * Cosign (Image Signing): Provides cryptographic verification of container images to prevent tampering and supply chain attacks. * Work with AI MCP servers to automate operational workflows and enhance developer experience. * Partner with engineering teams to define platform standards and best practices. * Mentor peers and promote automation-first culture. * Operate with minimal supervision and deliver solution-oriented outcomes.
