What we're looking for

• Hands-on experience with production Java/Scala services
• Familiarity with the Play Framework internals
• Spark experience for pipeline-heavy work
• Comfortable with OAuth-based authentication patterns
• React/TypeScript familiarity is a plus
• For DevOps-leaning candidates: experience with build systems

(Gradle), scripting, and CI/CD pipelines

Example of work tasks

• Modernise backend services and pipelines: upgrade to latest JDK, Scala 3.x, and Play Framework 3.x
• Apply GenAI tooling throughout to automate code transformations, dependency resolution, and compatibility fixes - producing reusable tools, prompts, and a documented runbook
• Migrate authentication across a large number of backend services from a legacy API to an OAuth-based solution.
• Replace per-unit data stores with a single versioned table: build Spark/Java batch pipelines for backfill/migration and extend Scala/Play backends

As it is a short term assignment, these skills are important, as it is crucial to quick come up to speed and be open to changes in work tasks during these months:

* Learning agility - Willing to pick up new technology, work with legacy code, and adapt quickly

* Communication - Easy to talk to, take feedback without defensiveness.

* Problem-solving clarity - Explain their thinking, ask clarifying questions
