Job Specifications

The client is looking for a UX Engineer with strong Android development skills. This role requires hands-on coding (Kotlin, Jetpack Compose) to build high-fidelity prototypes, not just design. It's ideal for someone who can merge UX sensibility with mobile development expertise in an R&D environment.

This role is perfect for a creative Android developer who loves experimenting with new ideas. You'll get to build interactive prototypes that shape the future of AI-powered tools, working closely with designers and researchers. If you enjoy coding polished UIs, rapid prototyping, and bringing innovative concepts to life, this opportunity will be exciting for you

Title: UX Engineer (Only W2)

Location - Mountain View, CA (3 Days onsite a week)

Duration: Long Term Contract

About the Role:

Job Specification: UX Engineer, Agentic Prototypes (Contractor) Team Overview: Our team is building the future of AI-powered software development, moving from high-level concepts to tangible, working prototypes. We are the bridge between visionary design and engineering reality, creating the interactive experiences that will define how developers and creators interact with autonomous AI agents.

Role Description: As a UX Engineer, you will be responsible for bringing our most ambitious design ideas to life. You will build high-fidelity, functional prototypes that explore the future of the IDE and agentic workflows. Working in a highly collaborative and fast-paced environment with 2-week sprints, your work will be critical for user testing, internal demos, and making concrete decisions about our product direction. You will be building the demos that inspire and the prototypes that prove what's possible.

Key Responsibilities:

Rapidly build interactive, high-fidelity prototypes of next-generation developer experiences, including multi-agent control panels and AI-first IDE concepts.
Develop functional Android app prototypes that showcase the output of our AI agents, helping to test and validate the end-to-end "vibe coding" experience.
Collaborate closely with UX designers to translate static mockups and design visions into dynamic, interactive experiences.
Work with UX researchers to build prototypes for user studies that test core assumptions about developer-agent interaction.
Leverage your mobile development expertise to ensure prototypes are realistic, performant, and effectively demonstrate key user journeys.

Minimum Qualifications:

Strong portfolio of work demonstrating excellence in front-end or mobile development, with a focus on building polished user interfaces.
Proven experience with mobile development and building Android applications.

Preferred Qualifications:

Expertise in the modern Android development toolkit, particularly Kotlin and Jetpack Compose.
Experience building plugins or extensions for IDEs (e.g., IntelliJ, VS Code).
A strong interest in generative AI, LLMs, and agentic systems.
Ability to work effectively in a fast-paced, ambiguous R&D environment.
