Core Responsibilities

Primary Functions

Lead end-to-end interaction design for new product features and cross-platform experiences, translating user needs and business objectives into intuitive user flows, wireframes, and interactive prototypes.
Conduct and synthesize user research and usability testing (moderated and unmoderated) to validate interaction patterns, identify usability issues, and iterate on designs based on real user feedback.
Create high-fidelity, responsive prototypes using tools like Figma, Sketch, Framer, or Adobe XD to communicate micro-interactions, transitions, and edge-case behaviors to stakeholders and engineering teams.
Define and document interaction patterns, atomic components, and behavior specifications that enable consistent cross-platform experiences and support scalable design systems.
Collaborate with product managers to define problem statements, prioritize features, and scope work for iterative sprints, ensuring design trade-offs are informed by user evidence and KPI targets.
Partner with front-end engineers to translate interactive prototypes into production-ready implementation, providing detailed interaction specs, motion guidelines, and accessibility requirements.
Facilitate cross-functional design critiques, walkthroughs, and alignment sessions to gather feedback, build consensus, and refine solutions prior to development.
Analyze qualitative and quantitative metrics (e.g., task success rate, conversion funnels, session recordings, A/B tests) to measure the impact of interaction changes and recommend data-driven optimizations.
Design accessible experiences that meet WCAG standards, implement keyboard and screen-reader interactions, and educate teams on inclusive design best practices.
Develop journey maps, service blueprints, and scenario-based flows to capture complex user interactions across touchpoints and reduce friction in multi-step processes.
Create robust design documentation and handoffs (interaction specs, states, error scenarios) to reduce rework and ensure fidelity between design and shipped product.
Drive rapid experiment cycles by ideating multiple interaction alternatives, building clickable prototypes, and coordinating lightweight tests to validate assumptions before full development.
Mentor junior designers and provide hands-on guidance on interaction patterns, prototyping techniques, and usability testing methods to raise the overall design quality of the team.
Contribute to the governance and evolution of the design system: propose new components, define interaction rules, and maintain shared libraries that accelerate product delivery.
Translate complex business logic and technical constraints into simplified user interactions that minimize cognitive load and support quick task completion.
Advocate for the user across product roadmaps, sprint planning, and stakeholder reviews, ensuring that user-centered metrics influence prioritization and success criteria.
Map and resolve edge cases and error states in interactive flows, producing clear recovery paths and microcopy improvements to reduce abandonment.
Lead accessibility audits and remediation efforts across interaction layers, coordinating with engineering to ensure accessible implementations at launch.
Produce design specs for animations, timing, and motion to communicate the intended feel and affordances of interactive elements to developers and QA.
Stay current with interaction design trends, emerging tools, and platform conventions (iOS, Android, Web) and incorporate best practices that improve usability and conversion.
Collaborate with analytics and data teams to instrument key interactions, define success metrics, and run hypothesis-driven experiments that optimize user engagement and retention.
Support cross-product initiatives such as onboarding flows, search and discovery interactions, and personalization mechanics to improve new-user activation and long-term engagement.
Prepare and present research findings, prototypes, and design rationale to executives and cross-functional partners, tailoring messages for technical and non-technical audiences.

Secondary Functions

Contribute to product roadmap discussions by providing interaction design estimates, risk assessments, and alternative solutions that balance speed and quality.
Maintain and evolve shared component libraries and pattern documentation in Figma or Storybook to support consistent handoffs and faster development cycles.
Participate in sprint planning, refinement sessions, and agile ceremonies to align on deliverables, timelines, and dependencies with engineering and PMs.
Provide ad-hoc design support for marketing, growth, and customer success teams to ensure a consistent brand and UX across acquisition, activation, and support flows.
Coach non-design stakeholders on basic UX principles and usability heuristics to improve cross-functional decision making and reduce design debt.
