Job Description

Our vision for the role

We are searching for an experienced Senior Cloud Infrastructure Security Engineer with an unquenchable thirst for automation and a passion for DevSecOps methodology. You'll be working with a team of other engineers to build out and secure our expanding cloud infrastructure in AWS. While this is a hands-on engineering position (not a CISO or a consulting role), you will need the confidence and gravitas to heavily influence engineers and managers across a wide technical function.

The team holds itself accountable to a high standard of build quality. We have recently completed the first major phase of a completely green-field infrastructure and platform rebuild that is designed to underpin Cint’s business applications for the next decade, while scaling to support a 10-fold growth in revenue. We are compulsive about infrastructure as code (nothing in our platform is created or deployed unless via a code change) and driven to achieve a full end to end continuous deployment pipeline.

Major elements of our platform include AWS (we make significant use of S3, RDS, Kinesis, EC2, EMR, ElastiCache, ElasticSearch and EKS). Elements of the platform will start to expand into GCP (Compute Engine, Cloud Storage, Google Kubernetes Engine and BigQuery). Other significant tools of the platform include Linux, Terraform, Kubernetes, Docker, Packer, Ansible and Jenkins. We support applications and services written in Golang, Python, Java, Scala and .Net. We monitor and alert on everything we deploy via Grafana, Prometheus, Graphite and ELK stacks.

You will be someone that shares our values and ambitions and can bring security best practices and specific cloud security expertise to the party. You will additionally be the kind of person that is energised by complex challenges, teamwork and problem solving. In return, we can offer a great tech culture, highly competitive compensation packages and employment benefits.
