Job description

Senior AWS DevOps Engineer

About Rayo

Rayo, part of UBDS Group, helps organisations design, build and operate secure, resilient cloud environments, with a strong focus on public sector and other complex, regulated environments.

We’re looking for an experienced Senior AWS DevOps Engineer to take a leading role in the design, build and delivery of cloud infrastructure and automation for our clients.

This is a hands‑on senior engineering role, combining deep AWS and DevOps expertise with technical ownership, client engagement and the ability to guide other engineers and influence engineering practices.

The Role

As a Senior AWS DevOps Engineer, you’ll take technical ownership of cloud infrastructure, CI/CD, infrastructure-as-code and deployment automation across client engagements.

You’ll work closely with architects, engineers, security specialists and client teams to design and implement solutions that are secure, resilient, scalable and repeatable.

Alongside hands‑on engineering, you’ll provide technical leadership, help establish engineering standards and practices, support less experienced engineers and contribute to key technical decisions throughout delivery.

What You’ll Do

• Lead the design, build and evolution of secure AWS cloud infrastructure and DevOps capabilities
• Design and maintain scalable, secure and automated CI/CD pipelines using GitLab or GitHub
• Own infrastructure-as-code approaches using Terraform, ensuring environments are repeatable, maintainable and compliant
• Define and promote engineering standards, patterns and best practices across delivery teams
• Embed automation across build, test, deployment and operational workflows
• Apply DevSecOps and security‑by‑design principles throughout the delivery lifecycle
• Design, deploy and operate containerised workloads using Kubernetes and AWS services such as ECS and EKS
• Work with architects and security specialists on cloud architecture, networking, identity, security and integration requirements
• Implement effective monitoring, observability, logging and alerting to support resilient services
• Provide technical leadership during complex troubleshooting and resolution of infrastructure and deployment issues
• Engage with clients and technical stakeholders to understand requirements, explain technical decisions and provide recommendations
• Mentor and support engineers, encouraging knowledge sharing and continuous improvement
• Identify opportunities to improve engineering practices, automation, reliability and delivery efficiency

What We’re Looking For

• Current SC clearance is highly desirable due to the nature and timescales of our client engagements. Candidates must be eligible to obtain and maintain SC clearance
• Significant hands‑on experience designing, building and operating solutions within Amazon Web Services (AWS)
• Strong knowledge of AWS compute, networking, identity, security and container services
• Strong experience designing and managing CI/CD pipelines using GitLab or GitHub
• Demonstrable expertise with Terraform and infrastructure‑as‑code at scale
• Strong understanding of Kubernetes architecture and operating containerised workloads in cloud environments
• Good understanding of DevSecOps, OWASP principles and security‑by‑design
• Experience designing and implementing monitoring, logging and observability solutions
• Strong scripting skills using Python, Bash, PowerShell or similar
• Experience making technical design decisions and providing engineering leadership within multidisciplinary teams
• Strong troubleshooting and problem‑solving skills across complex cloud environments
• Confidence working directly with clients and communicating technical concepts, decisions and recommendations
• Experience working within Agile delivery environments
• Experience supporting and mentoring other engineers

Desirable

• AWS Professional‑level certification, such as AWS Certified DevOps Engineer – Professional or Solutions Architect – Professional
• Strong experience delivering solutions for public sector, defence or other regulated clients
• Experience working within secure environments and understanding the associated security and assurance requirements
• Experience contributing to technical designs, architecture decisions and engineering standards
