About the Role:
The Trust Engineering team safeguards our marketplace by building secure, reliable, and user-friendly systems that protect our users and their transactions. We are looking for a Senior Android Engineer to strengthen our authentication and trust experiences across the Carousell Group.
You will design and build secure, scalable, and modular Android systems that power login, account protection, and fraud prevention. You’ll work across multiple domains — authentication, KYC, fraud prevention, and platform security — to improve user trust while maintaining seamless experiences.
This is a hands-on senior role where you’ll not only write high-quality code but also drive technical direction, influence architecture, and collaborate with platform and backend teams to shape how we scale security across the organization.
You will:
- Design, build, and maintain secure, reusable Android SDKs and components for authentication, identity, and trust.
- Drive adoption of modern authentication technologies such as passkeys, biometrics, device-bound tokens, Play Integrity API, and trusted device frameworks.
- Collaborate with backend, security, and product partners to design risk-based verification and identity protection systems.
- Champion modular and testable architectures (e.g., MVVM, MVI, Clean Architecture) to improve maintainability and developer experience.
- Leverage GenAI and agentic tools (e.g., coding copilots, AI-assisted testing, refactoring agents) to boost engineering productivity and reduce manual effort.
- Lead end-to-end project delivery, from RFC design and milestone planning to testing and rollout.
- Identify and resolve security, privacy, and performance issues early through proactive analysis and monitoring.
- Design and implement concurrent systems leveraging Kotlin coroutines or the RxJava framework.
- Contribute to platform evolution efforts like Kotlin Multiplatform, shared SDKs, or architecture unification.
- Enhance CI/CD pipelines, crash alerting, and observability to improve release stability.
- Mentor teammates, review designs and code, and foster a culture of security-first engineering excellence.
