Senior DevOps Engineer

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)

• AWS Certified Solutions Architect – Associate (Nice-to-have)

• AWS Certified Advanced Networking - Specialty (Nice-to-have)

Desired Qualifications:

• 5+ years of experience in DevOps/Platform Engineering roles

• Experience with multi-environment deployment strategies and release management

• Familiarity with Agile/Scrum delivery (Jira, Confluence)

• Experience with Git workflows and branching strategies

• Understanding of compliance and data sovereignty requirements (EU context)

• Interest or experience in AI-assisted development tools and workflows

• Strong communication skills and ability to work independently as an SME
