Our success to date is down to 500 passionate and brilliantly-talented people working together to harness the power of beauty, and the beauty of technology.

However, we are not even close to being done. Today, less than 5% of hair and beauty is booked online - that’s tiny. We believe that booking online is inevitable and our mission is to give every customer their perfect hair and beauty experience, and to revolutionise an industry.

You have strong Linux skills and are familiar with AWS, or a similar cloud provider.
You are experienced using Docker and also have some knowledge (and preferably practical experience) of container orchestration e.g. Kubernetes.
You are familiar with some of the rest of our tech stack, and can learn the remainder very quickly.
You have experience with some of: networking, security, logging, alerting and monitoring.
You have programming experience, you’ve written Infrastructure as Code and you may have worked with Java and/or NodeJS development teams.
You live and breathe DevOps culture and practices including CI/CD, automation and IaC and can coach teams to adopt these ideas.
You may have worked on distributed systems, and have an appreciation of highly available, self-healing systems.
You have experience working in, or closely with, Agile development teams.
You’re friendly, diligent and driven and you like having fun at work!
