Meet the DevOps team

In DevOps, we develop robust and scalable infrastructure across multiple AWS regions and support multiple development and Quality Engineering teams. We focus on reliability, security and continuous improvement.

What you'll do

To make this happen you will

Database & data platform management

Own the reliability, performance and capacity of RDS and Aurora PostgreSQL, DynamoDB, Valkey and OpenSearch, balancing availability and cost. Lead upgrades and migrations, maintain tested backup and recovery procedures, and work with developers to improve queries and data access patterns.

Infrastructure & reliability

Build and maintain secure, scalable and cost-aware AWS infrastructure across multiple environments and regions using Infrastructure as Code. Identify reliability risks and standardise infrastructure patterns to reduce failures and simplify operations.

CI/CD & automation

Understand existing processes, identify bottlenecks and automate repetitive work to deliver measurable improvements. Improve CI/CD pipelines and build reusable, self-service tooling for safe deployments and routine operational tasks.

Monitoring & incident response

Maintain actionable monitoring and alerts, lead complex incident investigations and implement fixes that prevent recurrence. Maintain practical operational runbooks and participate in the weekly out-of-hours on-call rotation.

Security & best practices

Apply secure defaults across infrastructure and data platforms, including least-privilege access, encryption and secrets management. Identify and address security gaps, keeping configurations and auditing aligned with AWS best practices.

Collaboration & technical leadership

Partner with development and QE teams on technical decisions, clearly communicating risks and trade-offs. Mentor engineers, review infrastructure and automation changes, and share knowledge to strenghten team capability.
