About the Job

  • Design, build, and ship Android features for cart, checkout, payments, order status, and post-order experiences using Kotlin, Coroutines/Flow, and Android Jetpack (including Compose or View-based UI as appropriate).
  • Integrate and optimize payment flows and SDKs (e.g., tokenization, 3DS, wallet support), partnering with payments and risk teams to deliver secure, compliant, and low-latency experiences.
  • Create reusable, well-documented modules and libraries used across multiple Instacart Android apps, improving consistency, reliability, and developer velocity.
  • Uphold quality with robust testing (unit, integration, and UI), code reviews, analytics-driven monitoring, and performance tuning to reduce crashes and regressions.
  • Own work end-to-end: participate in technical design, break down deliverables, implement features, launch with feature flags/experiments, and iterate based on data and feedback.
  • Contribute to incident response and on-call rotations as needed, proactively addressing root causes and driving long-term platform hardening.
  • Mentor other Android engineers through design guidance, pairing, and thoughtful feedback; help define team coding standards, patterns, and documentation.

Minimum Qualifications

  • 5+ years of professional Android development experience with Kotlin, shipping consumer apps to the Google Play Store.
  • 3+ years building large-scale, user-facing features with Android Jetpack (e.g., Lifecycle, Navigation, ViewModel) and Coroutines/Flow.
  • 2+ years working on transactional flows (e.g., cart, checkout, payments, order status) or integrating payment providers/SDKs (e.g., Stripe, Adyen, Braintree), including 3DS and tokenization.
  • Hands-on experience with dependency injection and networking on Android (e.g., Hilt/Dagger, Retrofit/OkHttp), and modular app architectures.
  • Proven track record of quality: unit and UI testing (JUnit, Mockito/MockK, Espresso), CI/CD workflows, and analytics/crash monitoring.
  • Experience collaborating with cross-functional partners (product, design, backend, data) to deliver measurable impact in a fast-paced environment.
  • Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent practical experience.

Preferred Qualifications

  • Production experience with Jetpack Compose at scale, including theming, state management, and interoperability with Views.
  • Background building shared Android libraries/SDKs consumed by multiple apps or teams, with clear APIs and documentation.
  • Experience with experimentation and feature flagging (e.g., A/B tests, phased rollouts) and data-informed iteration.
  • Familiarity with observability and performance tooling (e.g., Firebase/Crashlytics, Android Profiler, Datadog, custom metrics/logging).
  • Knowledge of security and compliance for payments (e.g., PCI DSS) and techniques for fraud/risk mitigation.
  • Exposure to GraphQL or gRPC, offline/latency-tolerant design, and/or Kotlin Multiplatform Mobile.
