AWS DevOps Engineer - AWS - Lambda - NodeJS - React

We’d all like amazing work to do, and real work-life balance. That’s waiting for you at Sainsbury’s. Think about the scale it takes for us to feed the nation. The level of data, transactions, and variety it involves. Then you’ll realise that ours is a modern software engineering environment because it has to be. We’ve made serious investment into a Tech Academy and into setting standards and principles. We iterate, learn, experiment, and push ways of working such as Agile, Scrum, and XP. So you can look forward to exciting opportunities in everything from AI to reusable tech.

About the role

• Help build and maintain CI/CD pipelines using GitHub Actions to support fast, reliable deployments across multiple environments, including for JavaScript/TypeScript and React applications.
• Work closely with engineers to improve local development and deployment workflows, aiming for speed, simplicity, and consistency — particularly in Node.js-based services.
• Support infrastructure-as-code using tools like Terraform and Serverless Framework, in AWS and Azure.
• Assist in maintaining and evolving monitoring, logging, and alerting systems like New Relic, with attention to Node.js observability needs.
• Contribute shared internal tools and automation scripts that reduce manual tasks and streamline delivery.
• Work on environment setup and lifecycle, potentially including ephemeral environments, UAT, staging, and production.
• Troubleshoot infrastructure and deployment issues and help keep systems running smoothly.
• Write clear documentation and guides to help others understand and use platform tools confidently.
• Stay up to date with platform and CI/CD best practices and help implement improvements as needed.

You’ll be a role model for best practices, championing a customer-centric mindset and a passion for creative problem-solving, as well as mentoring fellow engineers as a progressive member of the engineering community. We’d also like you to be yourself – analytical, curious, and unafraid to challenge the status quo.

More about the role

• You’ll work with technologies at an enterprise scale.
• You may be asked to participate in out-of-hours support and should aim to build reliability and fault tolerance into the product, as well as engineering systems that are simple to diagnose and fix.
• You’ll guide, support, and enable performance within the team through providing technical knowledge and ideas.

More about you

• Great expertise in modern cloud engineering practices, including deep knowledge of system architecture, reliability engineering, and DevOps principles.
• Proven experience of cloud architecture, container orchestration, infrastructure as code, and CI/CD.
• Self-driven and constantly striving to improve your team, division, and peers.
• Drive for advocacy of agile/lean delivery methodologies.
• A passion for delivering solutions to customers, owning the whole SDLC, and living the DevSecOps principles.
