Role Overview

We are seeking a UX Engineer (Design Engineer) who combines strong UX design expertise with front-end development skills.

This hybrid role requires someone who can design intuitive user experiences and also translate them into working front-end code, leveraging AI tools to accelerate development.

The ideal candidate is a full-stack designer who can move from design → prototype → code, working closely with product and engineering teams.

Primary Responsibilities:

UX / Product Design (~60%)

Own end-to-end UX workflows: research, user flows, wireframes, interaction design, and high-fidelity visual design.
Conduct user research (interviews, usability tests, contextual inquiry) with internal stakeholders to inform design decisions.
Design complex and multi-step workflows.
Create and maintain a consistent design language across the portal and CRM, ensuring visual polish, information density appropriate for users, and accessibility compliance.
Design for edge cases, error states, empty states, loading states, and offline/degraded scenarios.
Present design decisions clearly to the pod and stakeholders, articulating rationale grounded in user needs and business outcomes.

Frontend Engineering (~40%)

Prototype designs in React/TypeScript to validate interactions, test with users, and accelerate development handoff.
Ship production frontend code in partnership with the pod’s engineers — components, pages, animations, and interaction logic.
Own the fidelity of what gets merged: review pull requests for visual accuracy, interaction quality, and design intent.
Contribute to and extend the frontend component library, ensuring design tokens, spacing, typography, and motion are implemented consistently.
Collaborate daily with engineers on technical feasibility, component architecture, and frontend performance.
