Android Application Development

• Design, develop and maintain high‑quality Android applications using Java and Kotlin, following modern Android development practices and architectural patterns.
• Contribute to application design decisions with a focus on scalability, maintainability and security.

Security, Quality & Compliance

• Apply secure coding practices and contribute to the development of applications operating in regulated or security‑conscious environments.
• Support quality assurance activities through unit testing, integration testing and defect resolution.
• Participate in reviews and remediation activities arising from internal audits, testing or external requirements where applicable.

Legacy Transformation

• Contribute to the migration and refactoring of legacy Android codebases to modern architectures (e.g. modularisation, improved separation of concerns, reusable components).
• Support incremental modernisation while maintaining system stability and minimising disruption to users.

Performance & Observability

• Analyse and optimise application performance, including responsiveness, memory usage and startup times.
• Implement logging, monitoring and diagnostic capabilities to support production support and incident investigation.

Automation & CI/CD

• Contribute to the development and maintenance of automated build, test and deployment pipelines for Android applications.
• Support automated test execution and continuous integration practices to improve code quality and release reliability.

Collaboration & Mentoring

• Collaborate closely with QA engineers, product owners, delivery managers and other developers to align on priorities and delivery timelines.
• Participate in code reviews, share knowledge and mentor less experienced developers where appropriate.
• Contribute to post‑release reviews and root‑cause analysis for defects or production incidents.

Qualifications

• BS/MS degree in Computer Science, Engineering or a related subject

Essential skills

• Client-facing skills
• People management skills - introducing and building ways in which people can learn from each other, encouraging mentoring and the transfer of knowledge by designing and delivering learning interventions

• Has an innovative approach – a bold thinker and doer, matching creativity with vigilance
• High value on openness and transparency

Experience

• Strong hands‑on Android development experience using Java and Kotlin.
• Experience working with modern Android architectures, tooling and build systems.
• Familiarity with secure application development principles and best practices.
• Experience with automated testing and CI/CD pipelines for Android applications.
• Proficiency with common development tools including Android Studio, Gradle and Git; experience with CI tools such as Jenkins, GitLab CI or Azure DevOps is beneficial.
