About the Role
As a Senior Mobile Engineer on the Pet Experiences team, you'll build and own the iOS and/or Android experiences across our full pet product features — activity timelines, care routines, weekly roundups, lost pet alerts, and the integrations that extend our reach beyond the app. You'll work closely with cloud engineers and PM to take features from spec to production, own quality on your platform, and contribute to raising the bar for how the team builds.
You don't just use AI tools. You think natively in them. Your primary workflow involves orchestrating agents to create specs, generate code and tests, verify results, and perform reviews. You'll help establish and evolve AI-native engineering practices for the Pet Experiences team while delivering features that ship to production weekly.
This role is open to iOS or Android specialists or someone proficient in both. Tell us which platform is your home.
AI-Native Expectations
- Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete.
- Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship.
- Velocity: We expect senior engineers who use AI well to operate with meaningful leverage — doing more with the same time, taking on problems that would otherwise require a larger team.
- Team leadership: You share what works. You automate prompting strategies that others can build on.
- Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team.
What You'll Do
- Design, build, and ship mobile features for pet activity timelines, care coordination, weekly summaries, and lost pet alert flows — using AI (Claude Code) as a first-class collaborator in your daily development workflow.
- Use agentic workflows to increase delivery velocity without sacrificing quality: from generating feature scaffolding to writing and validating test coverage to root cause analysis during incidents.
- Collaborate with cloud, design, and product to define APIs, data contracts, and end-to-end workflows across the pet product surface.
- Consume event-driven data pipelines (trip/dwell events, care routines, Kafka-backed aggregations) and translate them into clear, reliable user experiences.
- Own feature quality on your platform — iOS (Swift, SwiftUI / RIBs, SPM) or Android (Kotlin, Jetpack Compose, Dagger) or both.
- Instrument features for observability, crash-free sessions, and quality compliance; partner with the release team on Crashlytics triage.
- Write clean, testable, performant code; contribute to CI/CD automation and improve team-wide engineering standards.
What We're Looking For
- 5+ years of experience shipping production iOS or Android applications at scale, or both.
- iOS: deep Swift, Combine/async-await, SwiftUI and/or UIKit, SPM, instrumentation.
- Android: deep Kotlin, coroutines/Flow, Jetpack Compose, Dagger/Hilt, Gradle.
- Hands-on experience prompting, evaluating, and building with LLMs — not just autocomplete, but as a genuine development partner.
- Deep experience with agentic workflows, prompt engineering, context window management, and MCP/function calling.
- A track record of using AI tooling to multiply your own output — faster specs, better test coverage, cleaner code, faster debugging.
- Strong experience with mobile architecture patterns, modularization, and dependency management at scale.
- Experience integrating with REST/gRPC backends, event-driven pipelines, push notifications, and persistent local storage.
- Ability to collaborate across teams (cloud, design, product) and articulate technical tradeoffs clearly.
- Bachelor’s degree or equivalent
Nice-to-Have
- Experience building consumer pet, health, or activity tracking products.
- Familiarity with event-driven data pipelines, time-series activity data, or aggregation services.
