• Contribute to engineering standards and development best practices

Skills & Experience

We’re looking for a strong hands-on developer with commercial experience across many of the following:

• Java
• Spring Boot
• REST API development
• Microservices
• Apache Kafka
• AWS
• Kubernetes / EKS
• Event-driven architecture
• Docker and containerisation
• CI/CD pipelines
• Automated testing
• Enterprise integration
• Distributed systems
• Secure software development
• Performance optimisation
• Agile software delivery

Most importantly, you’ll be someone who is comfortable getting into the code and building complex backend services, rather than operating primarily at an architecture or management level.

What’s on Offer?

• 6-month contract
• $700-$800 per day (inc. super)
• Hybrid working environment
• Major enterprise cloud transformation program
• Modern engineering stack including Java, Spring Boot, AWS, Kafka and Kubernetes
• Complex, high-volume development environment
• Work alongside highly experienced software engineers
• Opportunity to work on mission-critical systems at significant scale
• Immediate start available
