Senior Software Engineer - Service Security & Communication

The mission of the Service Security & Communication team is to provide secure and resilient inter-service communication, management of secrets and protection of sensitive data, across Tesco.

More specifically, our areas of responsibility include:

• Resilient and secure inter-service communication via service mesh and mTLS
• Desensitising secrets and data via encryption or signing
• Secure management of secrets via rotation and centralised management

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, to minimise support costs. We practice continuous integration and delivery which allow us to deliver business value frequently while minimising risk.

Our microservices use ReactiveX Java and are deployed to Kubernetes on AWS and Azure. We leverage a number of cloud services such as DynamoDB, Cosmos DB, S3, Blob Storage, KMS and Key Vault. Our CLIs are built 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.
