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). You will work closely with development squads to ensure fast, reliable, and secure delivery of enhancements and fixes.

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
  • Maintain and tune data infrastructure components (RDS PostgreSQL, ElastiCache Redis, DynamoDB, S3)
  • Review and improve disaster recovery strategies, backup automation, and rollback mechanisms
  • Support multi-account governance and cross-account resource management
  • 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:

  • Access and incentive to pursue multiple certifications (AWS, Azure, GCP, GitHub, AI, and more)
  • Be part of a 60+ DevOps engineering community, working across 25+ projects in different industries and countries
  • Collaborative environment with internal and external meet-ups, happy hours, and challenges beyond project work
  • Access to leading AI tools and platforms
  • Opportunity to work on a high-impact EU institutional project with modern serverless architecture
  • Active AI-First transformation with cutting-edge AI-assisted development practices

    • Required Technical Skills:

  • Advanced proficiency in Amazon Web Services (AWS) - multi-account environments
  • Strong experience with Infrastructure as Code (AWS CDK with Python/TypeScript; CloudFormation)
  • CI/CD pipeline design and management (CodeBuild, CodePipeline, or equivalent)
  • Containerization and orchestration (Docker, ECS/Fargate)
  • Serverless architecture (Lambda, API Gateway, Step Functions, EventBridge)
  • Networking (VPC, subnets, security groups, PrivateLink, CloudFront)
  • Monitoring and observability (CloudWatch, OpenSearch, structured logging)
  • Scripting and automation (Python, Bash, PowerShell)
  • Database operations (PostgreSQL, Redis, DynamoDB)
  • Security hardening (IAM, KMS, WAF, Secrets Manager)
  • Maintain and enforce security and quality gates across CI/CD pipelines (OWASP Dependency Check, Prowler, SonarQube, AWS Config, ECR image scanning)
  • FinOps fundamentals (cost allocation, tagging strategies, resource optimization)

    • Certifications:

  • AWS Certified Developer - Associate (Must-have)
  • AWS Certified DevOps Engineer – Professional (Nice-to-have)
  • AWS Certified SysOps Administrator – Associate (Nice-to-have)
