About the Role:

We are looking for a Senior DevOps Engineer to maintain, optimize, and continuously improve the CI/CD platform, infrastructure-as-code, and operational practices for a mature, stable multi-environment AWS ecosystem. The solution is fully developed and in production; the focus is on continuous improvement, cost optimization, reliability, and operational excellence. Additionally, the project is undergoing an AI-First transformation, adopting AWS Kiro and custom AI agents to implement an AI-driven Development Lifecycle (AI-DLC).

Key Responsibilities:

- Maintain and evolve CI/CD pipelines (AWS CodeBuild, CodePipeline) ensuring reliability and speed of delivery

- Maintain and improve Infrastructure as Code using AWS CDK (Python primarily, some TypeScript) across multiple AWS accounts

- Optimize serverless infrastructure performance, cost, and reliability (Lambda, API Gateway, AppSync, Step Functions, EventBridge)

- Improve and extend observability solutions (CloudWatch, OpenSearch dashboards, structured logging, alerting)

- Continuously strengthen security posture including IAM policies, KMS encryption, Secrets Manager, and network segmentation

- Collaborate with development teams on deployment strategies (blue/green, canary, feature flags)

- Drive operational excellence through runbooks, incident response procedures, and post-mortem processes

- Apply FinOps practices to monitor, optimize, and report on cloud cost and resource utilization

- Identify and implement continuous improvement initiatives across infrastructure, pipelines, and operational processes

- Contribute to the AI-First transformation by integrating AI agents and AI-assisted workflows into the development and operations lifecycle

- Troubleshoot production issues and perform root cause analysis

- Mentor junior team members on cloud infrastructure and DevOps practices

Key Challenges:

- Sovereign Cloud: reduce footprint on vendor lock-in AWS solutions and migrate workloads toward containers and cloud-native standard technologies

- Migration and Modernization: plan and execute application and workload migration to AWS through 2029

- Propose improvements and new solutions at the weekly architecture board for cost reduction, operational improvements, and adoption of new AWS or market features

What We Offer:
