* Orchestrating workflows and event-driven systems

* Managing containerised services with Docker and ECS

* Setting up monitoring, alerting, and reliability practices

* Optimising performance, cost, and scalability

* Baking in security and least-privilege access from day one

* Experimenting with AI tools and agents to automate workflows and improve productivity

What We’re Looking For

* Strong AWS experience (especially ECS, Lambda, Step Functions, S3, Event Bridge)

* Solid Docker and container-native deployment experience

* Python for data processing and automation

* Experience building data pipelines and data lake architectures

* Infrastructure-as-code (Terraform, CDK, or Cloud Formation)

* CI/CD and production engineering mindset

* Systems thinking and comfort owning production workloads

* Curiosity about AI tools, LLMs, and automation

Why Join

* Real ownership of core infrastructure and architecture

* Work at the intersection of cloud, data, and applied AI

* Modern AWS stack, event-driven design, and production scale
