Job description

Senior Android Developer - Hybrid

Important Disclaimers:

**Please note: A few of our roles may require in-person interviews at Cognizant offices or client locations, depending on project or client needs.**

In this role, you will:

• Define clean architecture patterns and Android Jetpack based modular designs that promote separation of concerns, testability, maintainability and clear boundaries between presentation, domain and data layers.
• Drive adoption of modern asynchronous and reactive patterns using Coroutines and Rx JAVA to improve app responsiveness, simplify concurrency handling and reduce issues related to threading and resource contention.
• Optimize app performance by profiling startup time, memory usage, network calls and rendering pipelines, then implementing targeted improvements in Compose UI, data access and caching strategies.
• Implement and review robust Android security controls covering secure storage, network encryption, authentication flows and protection against common mobile threats to safeguard sensitive data and user trust.
• Establish comprehensive Android testing strategies including unit tests, instrumentation tests and UI tests, and integrate them within continuous integration pipelines to maintain high release quality and rapid feedback.
• Collaborate with product, design and backend engineering to translate business requirements into Android focused technical solutions that balance usability, maintainability and long-term platform evolution.
• Guide teams on effective use of Android Jetpack libraries for navigation, lifecycle management, dependency injection and data persistence to reduce boilerplate and align solutions with recommended platform practices.
• Shape app distribution strategies through Play Store configuration, build variant management, feature flagging and phased rollout plans that minimize risk while enabling frequent and reliable releases.
• Ensure Android accessibility best practices are embedded in Compose UI components, layouts and interactions so that applications remain inclusive, navigable and compliant for users with diverse abilities.
• Provide structured debugging support for complex production issues by using profiling tools, logs and crash analytics, and translate findings into durable fixes that improve platform stability and customer experience.
• Design and develop AI agents for vulnerability discovery, triage, root-cause analysis, and remediation across native mobile applications.
• Build workflows that inspect source code, dependencies, platform configurations, and data flows to identify security weaknesses.
• Enable agents to detect issues such as insecure data storage, sensitive information
  exposure, weak cryptography, insecure network communication, and authentication or authorization flaws.
• Integrate security scanning tools and their findings into agent workflows to improve detection accuracy and reduce false positives.
• Enable agents to generate targeted fixes, create regression tests, run builds and security checks, and prepare pull requests with supporting evidence.
• Collaborate with application security, architecture, mobile engineering, and QE teams to validate and improve agent behavior.
