This is a rare opportunity for an experienced Senior Cloud / Platform Engineer to be part of something big, early on - driving performance, resilience and automation across a modern, cloud-native stack. You'll play a crucial role in building, maintaining, and improving the platforms that underpin everything from product delivery to developer velocity.

If you are a Senior Cloud / Platform Engineer, and you are looking for a role where you can work with cutting-edge technology across DevOps and AI-native development tools, while having an opportunity to influence architectural decisions and take ownership of the platform as the company scales rapidly - then this one is for you!

• Performing cost optimisation, security hardening, and proactive infrastructure fixes
• Leading internal pen testing and collaborating on platform security improvements
• Maintaining the company's CI procedures and deployment processes
• Using Terraform and/or CloudFormation for Infrastructure as Code
• Working with MySQL databases (Aurora) and other AWS services such as EC2, RDS, Lambda, ElastiCache, and DocumentDB

The Person

• You have proven experience as a Cloud, DevOps, or Platform Engineer, ideally in a scaling or high-growth environment
• Deep hands-on expertise with AWS (e.g. EC2, RDS, EKS, Lambda, CloudWatch, SecretsManager, ElastiCache, DocumentDB), with experience designing secure and reliable cloud architectures.
• Solid understanding of Kubernetes (EKS preferred) and container orchestration
• Strong scripting skills - you're confident automating processes in Bash, Groovy, or similar
• Proficient in building and managing robust CI/CD pipelines
• You're passionate about platform security, observability, and continuous improvement
• Comfortable collaborating across product and engineering teams to improve workflows and reliability
• You have a keen eye for performance and cost efficiency in cloud architecture
