Backend Developer

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

* Hands-on experience using Claude Code or similar GenAI tool in day-to-day

work.
