• Develop and implement advanced CI/CD strategies to support complex, large-scale cloud solutions on AWS.
• Engage directly with clients to provide technical expertise, offer solutions to complex cloud challenges, and act as a trusted advisor in their cloud journey.
• Lead technical discussions with developers and stakeholders, influencing architectural decisions and setting DevOps standards across teams.
• Drive continuous improvement initiatives by automating repetitive tasks, remediating technical debt, and identifying opportunities for optimization.
• Mentor and coach junior engineers, fostering a culture of knowledge sharing and continuous learning.
• Stay up to date with the latest cloud technologies, DevOps tools, and industry trends, recommending new approaches to enhance our services.

What experience you'll bring:

• 10+ years of experience in provisioning, configuring, and maintaining AWS Cloud environments, with a focus on large-scale, mission-critical infrastructures.
• In-depth expertise in a wide range of AWS service offerings, including Compute, Management & Governance, Storage, Security, Identity & Compliance, Networking & Content Delivery, FinOps, Containers, and Database products.
• Extensive hands-on experience with Infrastructure as Code (IaC) tools such as AWS CloudFormation, Terraform, or CDK, with a proven track record of automating cloud infrastructure deployments.
• Advanced knowledge of containerization technologies and orchestration platforms like Docker and Amazon EKS (Kubernetes) or ECS.
• Expertise in defining, implementing, and optimizing CI/CD pipelines using tools such as AWS CodePipeline, Jenkins, GitLab, GitHub Actions, and others, applying best practices for pipeline efficiency and security.
• Strong background in networking, Linux or Windows administration, with the ability to architect secure, performant, and highly available cloud solutions.
• Proficiency with monitoring and log analytics tools such as AWS CloudWatch, ELK Stack, Prometheus, Datadog, or New Relic, to maintain observability and ensure operational excellence.
• Demonstrated leadership skills in managing complex, high-pressure situations and guiding teams through incident resolution.
• Exceptional communication and presentation skills, with proven experience engaging with senior stakeholders.

Nice to Have:

• Relevant AWS certifications.
