We're partnering with a growing technology-led business operating a large-scale cloud platform and looking to add a hands-on DevOps Engineer to their engineering team.

This is an ideal opportunity for someone who enjoys solving problems, building solutions from scratch, and taking ownership of cloud infrastructure rather than simply maintaining existing environments. You'll work as part of cross-functional product teams, helping to improve platform reliability, scalability, security and developer efficiency across a predominantly AWS estate.

The team values curiosity, initiative and continuous improvement. They're looking for someone who enjoys learning, challenges the status quo and takes pride in delivering meaningful engineering outcomes.

The Role

You'll work closely with software engineers, QA engineers and data teams to design, build and optimise infrastructure that supports business-critical applications and data platforms.

Responsibilities include:

• Building and improving AWS infrastructure using Infrastructure as Code
• Creating and enhancing CI/CD pipelines and deployment processes
• Supporting the infrastructure behind data and ETL platforms
• Improving platform reliability, observability and performance
• Identifying opportunities for automation and cost optimisation
• Contributing to cloud security best practices and infrastructure governance
• Troubleshooting complex production issues and acting as a technical problem solver
• Supporting SRE initiatives across the platform
• Collaborating with globally distributed engineering teams across Europe and India

What They're Looking For

• Strong hands‑on AWS experience
• Experience with Terraform for Infrastructure as Code
• Good understanding of networking concepts including VPCs, routing and autoscaling
• Experience with monitoring and observability tools such as CloudWatch, Datadog or similar
• Knowledge of cloud security principles and AWS best practices
• Experience building, improving and automating infrastructure rather than purely supporting it
• Strong troubleshooting and problem-solving skills
• Comfortable working across a broad range of DevOps, platform and SRE responsibilities

Nice to Have

• OpenSearch experience
• Exposure to Azure environments
• Scripting and automation experience

The Team

You'll join a close-knit engineering function where DevOps plays a central role in product delivery. Engineers work within cross-functional squads, taking ownership of both project-based initiatives and ongoing platform improvements.

The environment suits someone who enjoys variety, autonomy and responsibility. There is genuine opportunity to develop new skills, influence technical decisions and grow within the business.
