We’re looking for an experienced Scala developer to implement a small, well-scoped backend enhancement in our platform.


Scope & deliverables


  • Add/modify one REST endpoint in a Scala service (Play Framework preferred; Akka HTTP also fine).

  • Implement business logic to transform and validate payloads.

  • Integrate with PostgreSQL via a simple repository (CRUD + 1 custom query).

  • Provide unit tests and a short README explaining how to run locally with sbt test and sbt run.

  • Create a lightweight CI step (GitHub Actions or GitLab CI) to run tests and scalafmt.

  • Handover: PR with reviewed code, test coverage report, and brief change log.


Tech stack (our environment)


  • Scala 2.13/3, sbt

  • Play Framework or Akka HTTP

  • Cats / Cats-Effect (optional but nice)

  • PostgreSQL (JDBC/Doobie/Slick—your choice, keep it simple)

  • JSON (circe or Play JSON)

  • Docker for local DB (optional)


What we provide


  • Access to a minimal repo with starter code and models

  • Example payloads + OpenAPI/Swagger snippet

  • Test DB schema and sample data


What we expect from you


  • 3+ years building production services in Scala

  • Clean code, idiomatic FP or pragmatic style, with tests

  • Clear communication and on-time delivery

  • Ability to suggest small improvements (error handling, logging, config)
