Nature of work
· Data access and persistence
Build and maintain Java backend components with multithreading, collections/stream APIs, and strong OOP/design patterns, while also working with Oracle/Sybase databases, Unix, and DevOps/scripting across the dev lifecycle.
"Strong database knowledge (Oracle and Sybase preferred)."
Tech stack maturity
Mainstream Modern
The skill set centers on Java, multithreading, algorithms, design patterns, and DevOps, which is typical of a current mainstream backend stack rather than bleeding-edge or legacy-only technology.
