Lead DevOps Engineer

Andersen is hiring a Lead DevOps Engineer for a project modernizing CI/CD processes and enhancing a cloud-based software quality platform with scalable public API capabilities. The customer is a technology-driven software quality services provider that helps organizations improve the reliability, usability, and performance of their digital products. It combines quality engineering expertise, flexible delivery models, and technology-enabled services to support web, mobile, and other digital solutions across multiple industries. The company helps businesses accelerate software delivery, improve product quality, and enhance end-user experience through scalable testing and quality assurance services. The project is focused on preparing a cloud-based software quality platform for public API exposure by delivering a public API documentation portal and status page. It also includes modernizing CI/CD processes through migration from CircleCI to GitHub Actions and integrating standardized reusable workflows across multiple repositories.

Responsibilities: - Building and maintaining the public API documentation pipeline, including OpenAPI specification aggregation, validation, bundling, and publishing with Stoplight Elements. - Integrating documentation pipelines into GitHub Actions reusable workflows. - Evaluating, recommending, and implementing a public status page using New Relic Synthetics as the uptime monitoring source, including component-level alert policies and incident workflows. - Managing monitoring and alerting infrastructure as code using Terraform, following the client's existing conventions and patterns. - Supporting live production changes and migrations on AWS ECS Fargate, including service migrations, load balancer changes, and cluster-level changes with zero or minimal downtime. - Owning release engineering for client-facing deliverables: design and manage safe, repeatable release processes (deployment strategies, health checks, automated rollback, release governance and change management). - Contributing to the ongoing migration from CircleCI to GitHub Actions across 111 repositories by integrating new pipelines into reusable workflow templates. - Embeding security and quality gates into CI/CD pipelines using Snyk and SonarQube (SAST, dependency/vulnerability scanning, code quality) as part of the release process. - Working closely with development teams and leading a dedicated DevOps team. The role is focused on delivering and supporting client-facing products rather than working exclusively on internal infrastructure. - Taking ownership of tasks end-to-end: understand the problem, define the approach, implement the solution, and drive it through to production safely. - Making independent technical decisions, communicating trade-offs clearly, and ensuring reliable execution in production environments.

Requirements: - Experience in DevOps, Platform Engineering, or a similar role, with strong hands-on experience in AWS for 7+ years. - Deep expertise in Amazon ECS/Fargate, including Service Connect, Graviton and multi-architecture builds, cluster design, load balancers (ALB/NLB), target groups, and deployment strategies. - Proven experience performing live production migrations and infrastructure changes, with a strong understanding of blast radius, rollback strategies, and zero-downtime deployments. - Strong hands-on experience with GitHub Actions, including reusable workflows, composite actions, and OIDC/IAM integration. - Solid release engineering background: designing and running release pipelines, deployment strategies (blue/green, canary, staged rollouts), health checks, automated rollback, and release/change governance. - Hands-on experience with Terraform in established codebases and the ability to work within existing architecture, conventions, and patterns. - Experience with New Relic, particularly Synthetics, alert policies, APIs/webhooks, and NerdGraph; or strong experience with an equivalent observability platform such as Datadog or Grafana, with the ability to ramp up quickly. - Hands-on experience with security and code-quality tooling in CI/CD: Snyk and SonarQube (SAST, dependency and vulnerability scanning, code quality gates). - Experience with AWS CloudFormation (and Terraform) for infrastructure-as-code in AWS environments. - Experience with OpenAPI tooling and docs-as-code pipelines. - Strong senior-level autonomy: ability to take ownership of a task from problem definition through production deployment with minimal supervision. - Proven ability to work responsibly with elevated and production access, following structured and reliable engineering practices. - Strong technical judgment: able to evaluate trade-offs, communicate reasoning clearly, and make well-founded recommendations even when information is incomplete. - Kubernetes is not required — the platform is primarily based on ECS/Fargate. - Level of English – from Upper-Intermediate and above.

Nice to have: - Experience with API documentation and developer portal tools such as Stoplight Elements or ReadMe. - Experience with status-page platforms such as Atlassian Statuspage or Better Stack. - Hands-on experience migrating CI/CD pipelines from CircleCI to GitHub Actions. - Familiarity with OpenTelemetry. - Experience with AWS Infrastructure-as-Code tools such as CloudFormation and SAM. - Mature experience with AI-assisted development workflows, including the ability to critically review, verify, and validate AI-generated output and explain the resulting implementation and technical decisions to the team.

Compensation: 4050–6000 EUR per month.
