- Designing and developing scalable Python-based cloud applications, APIs and microservices
- Working across Azure Functions, serverless, containers, APIM and cloud services
- Designing event-driven and integration architectures across complex enterprise environments

- Working closely with architects, product owners, delivery teams and senior stakeholders
- Mentoring engineers and helping raise technical capability across the wider team
- Driving modernisation, automation, CI/CD and continuous improvement

What we’re looking for:
- Strong commercial Python engineering experience
- Solid hands-on Microsoft Azure or AWS experience
- Strong understanding of REST APIs, microservices and event-driven architecture

Your very own career expert that helps elevate your application to the next level.
Experience with Azure DevOps/GitLab CI, Terraform, IBM ACE or API Connect would be advantageous.
