About the role
The mission of the Service Communication & Security team is to provide performant, resilient and secure interservice communication, across our cloud and till estate. We are part of the Engineering Effectiveness organisation within Tesco Technology.
More specifically, our areas of responsibility include:
- Resilient and secure interservice communication via service mesh and mTLS
- Desensitising secrets and data via encryption or signing
- Secure management of secrets via rotation and centralised management
- Removal of secrets via workload identities i.e. SPIFFE
We build and operate a set of cloud-native services, infrastructure and CLIs. Tesco’s large footprint means that our systems operate at vast scale and our clients require > 99.9% availability.
We obsess about system operability and as such focus heavily on observability, fully automated deployments, continuous improvement, and refinement in turn minimising support costs. We practice continuous integration and delivery which allow us to deliver business value frequently while minimising risk.
Our microservices are built using Java (using Micronaut and VertX) and are deployed to Kubernetes on Azure. We also leverage several cloud services such as Cosmos DB, Blob Storage and Key Vault. We build CLIs for our engineering teams using Go, allowing us to cross-compile to multiple operating systems. In addition, we also use Python, Bash and Terraform extensively in order to achieve a high level of automation.
The culture at Tesco Technology values above all else autonomy and full end-to-end ownership of solutions, thus empowering teams to build and deliver software as effectively as possible.
