This role offers exceptional scope and measurable impact on millions of shoppers and delivery people daily.

You will partner closely with Product, Design, Data Science, and various cross-functional teams across Instacart to design, ship, and iterate on features that drive key business outcomes at scale.

Key Responsibilities

• Design, build, and ship high-quality Android features in Kotlin to drive shopper activation, engagement, retention, and earnings across the shopper lifecycle.
• Own features end-to-end, from ideation and technical design through implementation, experimentation, launch, and ongoing iteration, balancing velocity with reliability and quality.
• Collaborate with Product, Design, and Data Science to define problem statements, build metrics and dashboards, run A/B tests, and make data-informed decisions to improve marketplace health.
• Contribute to and evolve app architecture, ensuring scalable patterns, robust dependency injection, and maintainable code to improve developer productivity and release reliability.
• Uplevel operational excellence by improving performance, stability, monitoring, and observability; participate in code reviews and contribute to engineering best practices.
• Partner with platform and service teams to integrate APIs, ensuring security, privacy, trust, and safety are primary considerations in all experiences.

Requirements

Minimum Qualifications

• 5+ years of professional Android development experience with Kotlin.
• 2+ years building consumer-facing, application-layer features used at scale (e.g., activation, onboarding, engagement, growth, or earnings experiences).
• Proficiency with RxJava and Dagger; working knowledge of Jetpack Compose in production or migration contexts.
• Proven track record of owning features end-to-end (technical design, implementation, testing, release, and iteration) and delivering measurable impact.
• Experience collaborating closely with Product, Design, and Data Science to define requirements, instrumentation, and success metrics.
• Strong computer science fundamentals (data structures, algorithms, concurrency).
• BS in Computer Science or related field, or equivalent practical experience.

Preferred Qualifications

• Experience with Kotlin Coroutines, Gradle build tooling, and modern Android architectural patterns (e.g., MVVM/MVI, modularization).
• Background in high-scale consumer marketplaces, logistics, or growth/engagement domains.
• Hands-on experience with experimentation and analytics (A/B testing, feature flags, metrics dashboards; SQL or BigQuery is a plus).
• Demonstrated success in fast-paced, rapidly changing environments with a bias toward ownership, operational rigor, and high-quality execution.
