Software Engineer

Pinterest is a platform that helps people discover creative ideas and plan meaningful experiences. The Software Engineer will build Android prototype tooling, reusable components, and AI-enabled workflows while partnering with designers, UX Engineering, Production Engineering, and the Gestalt Design System team.

Responsibilities:

• Build and evolve Android prototype foundation tooling that enables designers and cross-functional partners to create high-quality, interactive prototypes more quickly and consistently
• Develop reusable starter templates, component patterns, and technical foundations that accelerate prototyping workflows across product areas
• Create tools and systems that help designers leverage AI in the prototyping process when using native Android frameworks, including structured flows, automation, and agentic capabilities
• Partner with internal tooling teams to document and test workflows for prototype generation, packaging, and distribution
• Establish best practices for Android prototyping architecture, maintainability, performance, and extensibility to support rapid experimentation
• Contribute to the definition of new workflows, platforms, and internal capabilities that improve how teams explore, validate, and communicate product ideas
• Assist the Gestalt Design System team with Android-specific deliverables and dependencies, helping ensure design system foundations, components, and prototype tooling align with broader platform needs and timelines
• Document systems, templates, and usage patterns so tools are approachable, durable, and easy for others to adopt
• Lead cross-functional communication and collaboration between Design, UX Engineering, and Production Engineering to align on workflows, priorities, and implementation quality

Requirements:

• 7–10 years of professional experience building native Android applications
• Strong proficiency in Kotlin
• Hands-on experience with both Jetpack Compose and XML-based views
• Proven experience building or maintaining a design system, component library, or reusable UI foundations used by other teams
• Ability to explain technical concepts clearly to designers, product managers, and other non-technical partners
• 5+ years of experience building native Android applications or tooling using Kotlin and modern Android frameworks
• Strong understanding of UX engineering principles, with experience building prototypes, design systems, internal tools, or front-end foundations that bridge design and engineering
• Experience creating reusable technical frameworks, starter kits, templates, or infrastructure that improve team velocity and consistency
• Familiarity with AI-enabled workflows, automation, or agent-based tooling, and curiosity about how AI can support design and prototyping workflows
• Ability to work fluidly across design and engineering disciplines, turning ambiguous concepts into practical tools and polished prototype experiences
• Strong product thinking and craft, with attention to interaction quality, usability, performance, and developer/designer experience
• Experience collaborating in highly iterative environments, incorporating feedback quickly, and balancing speed with scalable implementation decisions
• Clear communication skills and a proactive, low-ego approach to partnering with designers, engineers, and cross-functional stakeholders
• Experience with Jetpack Compose is strongly preferred
• Experience with Android animation
• Experience building prototypes, internal tools, or design-to-code workflows
• A strong eye for UX, interaction quality, and design craft
• Familiarity with AI-enabled or agentic workflows
