Nature of work · Software Development / Engineering

Build and support Java/J2EE software end to end: design architecture, write and test code, debug production issues, ship via CI/CD, and join code/design reviews. Also collaborate with product/business partners and improve cloud, automation, and Agile delivery practices.

"• You will design, develop, test, deploy, maintain and improve software"

Tech stack maturity

Mainstream Legacy

The skill set centers on Java/J2EE, Angular, Bootstrap, and CI/CD, which is common in established enterprise environments rather than cloud-native or bleeding-edge stacks.
