The Role

At Thrive Market, our ML team works closely with Product Managers and Feature teams to enable experiences that define how our members shop, save, and stay loyal. This is a foundational hire within a net-new product engineering group focused on Personalization, AI, and ML Enablement; meaning you won't just inherit a slice of the product as-is; you'll be shaping how intelligent, personalized experiences reach members on their most personal devices.

As a Senior Software Engineer, Mobile, you'll own the full mobile surface across iOS and Android; from building polished, performant native experiences in Swift/SwiftUI and Kotlin to integrating the backend services and APIs that power them. You'll also work within and modernize legacy Objective-C and Java codebases, evolving them toward modern architectures. If you're energized by ambiguity, care deeply about craft on mobile, and want your architectural decisions to directly impact how over 1.7 million members experience Thrive Market; this is the role.

Responsibilities

• Design and build native mobile features in Swift/SwiftUI (iOS) and Kotlin (Android) that are fast, accessible, and polished at every interaction.
• Integrate with backend services and REST/RPC APIs to deliver personalized, data-driven product experiences on mobile.
• Work within legacy Objective-C and Java mobile codebases while actively driving their modernization toward current frameworks and patterns.
• Decompose tightly coupled mobile architectures into modular, testable, and maintainable components.
• Apply strong software development principles and practice test-driven development from the start; unit tests, UI tests, and meaningful observability are table stakes.
• Collaborate closely with Product, Design, and Data in the Product Triad model; translate business problems into technical specs and realistic sprint goals.
• Instrument mobile experiences with meaningful metrics; own reliability and performance SLAs for what your pod ships.
• Elevate the team through thoughtful code review, architectural discussions, and documentation of mobile best practices.
• Work with cross-functional partners to diagnose and resolve production issues, including crash triage and release health monitoring.

Qualifications

• 7+ years of hands-on mobile engineering experience (or equivalent scope at a hyperscaling company), with meaningful production time on both iOS and Android.
• Strong proficiency in Swift and SwiftUI for iOS development; solid Kotlin experience for Android.
• Experience building and consuming REST and RPC APIs from mobile clients at scale.
• Working knowledge of mobile CI/CD pipelines, app distribution (TestFlight, Play Console), and release management.
• Familiarity with relational and non-relational data persistence on mobile (Core Data, Room, Realm, SQLite) and when to use each.
• Experience with mobile observability and monitoring tools (Firebase Crashlytics, Datadog, New Relic, or similar) to maintain crash-free rate and performance targets.
• Comfort working in and modernizing legacy mobile codebases; Objective-C on iOS, Java on Android; you don't need a greenfield project to do your best work.
• Strong communication skills; can articulate tradeoffs clearly and influence architectural decisions across teams.
• Experience with agile development and collaborative Git workflows.

Nice To Have

• E-commerce or high-traffic consumer-facing mobile product experience.
• Experience with server-driven UI patterns or feature flagging on mobile (LaunchDarkly, Optimizely, or similar).
• Familiarity with on-device ML frameworks (Core ML, ML Kit) or integrating ML-powered features into mobile apps.
• Experience with Kotlin Multiplatform (KMP) or other cross-platform strategies.
• Working knowledge of AWS services and serverless patterns as they relate to mobile backends.
• Experience with A/B testing frameworks on mobile.
• Familiarity with accessibility standards and tooling for iOS and Android (VoiceOver, TalkBack).

Belong to a better company

• Comprehensive health benefits (medical, dental, vision, life and disability)
• Competitive salary (DOE) + equity
• 401k plan
