- Bachelor's degree in Computer Science, Engineering, or related field.
- Strong proficiency in GIT for version control and collaborative development.
- Proficiency in Android Kotlin front-end development.
- Happy to develop PoC applications where requirements may change rapidly and rework is common.

- Experience with Docker for containerisation and deployment.
- Knowledge of DevOps processes, including CI/CD pipelines and automated testing frameworks.
- Strong communication and collaboration abilities within a team environment.
- Ability to adapt to a fast-paced, dynamic work environment and learn new technologies quickly.
