[Hiring] Senior Android Engineer @Sword

Role Description

As an Android Engineer in Consumer Growth at Sword, you’ll build experiences that turn initial interest into lasting engagement with our consumer products. You’ll work across acquisition entry points, onboarding, subscription conversion, activation, and retention. Partnering with Product, Design, Data, Marketing, and backend engineers, you’ll ship experiments, understand their impact, and evolve successful ideas into high-quality Android experiences. This role combines native Android engineering with product curiosity: you’ll help determine what to improve, how to measure it, and what to build next.

• Build and improve Android experiences across onboarding, account creation, paywalls, subscriptions, and ongoing engagement;
• Create smooth transitions from acquisition campaigns and web journeys into the app through deep links and reliable navigation;
• Implement subscription purchase flows, purchase restoration, and entitlement handling in collaboration with backend engineers;
• Deliver controlled experiments using feature flags, targeted experiences, and accurate analytics instrumentation;
• Partner with Product, Design, and Data to identify friction, define experiment requirements, and evaluate results after release;
• Build reusable UI components and application foundations that make subsequent experiments easier to deliver;
• Maintain app performance, accessibility, stability, and responsive behavior across supported devices and Android versions;
• Own features through implementation, testing, release, monitoring, and iteration;
• Use AI tools to accelerate development while validating generated code and preserving engineering quality.

Qualifications

• Experience shipping and maintaining production Android applications;
• Strong proficiency in Kotlin and experience building interfaces with Jetpack Compose;
• Solid understanding of Android architecture, lifecycle management, coroutines, state management, and navigation;
• Experience integrating APIs and handling loading, failure, and interrupted user journeys gracefully;
• Experience with automated testing, debugging, and performance analysis;
• Ability to instrument user journeys and use product data to inform engineering decisions;
• Good product judgment and attention to interaction quality, accessibility, and user trust;
• Ability to work across disciplines, communicate trade-offs, and own features from concept through production;
• Practical experience using AI in your engineering workflow and critically reviewing its output;
• Fluent English, written and spoken.

Requirements

• Experience with Google Play Billing, subscriptions, or RevenueCat;
• Experience with A/B testing, feature flags, acquisition attribution, or Android App Links;
• Experience improving conversion, activation, or retention in a consumer application;
• Familiarity with push notifications and lifecycle engagement experiences.
