Job brief

We are looking for a creative Interaction Designer to join our product team and define the future of our digital interface. You will lead the transition from wireframes to high-fidelity, interactive prototypes that bring our software to life for millions of users. By collaborating with product managers and engineers, you will solve complex navigation challenges and ensure every interaction feels fluid, accessible, and purposeful. If you are passionate about the intersection of behavioral psychology and digital design, we want to help you shape our platform’s user experience.

Key highlights

  • Design and document high-fidelity interactive prototypes using Figma or Protopie to communicate complex user journeys to cross-functional engineering teams.
  • Define clear motion design guidelines and animation states that enhance feedback and accessibility within our primary web and mobile product suites.
  • Conduct iterative usability testing sessions to identify friction points and validate interaction models against established user behavior metrics.
  • Collaborate with UI developers during the technical hand-off phase to ensure complex transitions meet performance requirements and accessibility standards.

What is a Interaction Designer?

An Interaction Designer is a specialized UX professional focused on the 'moment of truth' where a user engages with a digital interface. By bridging the gap between static visual design and functional software engineering, an Interaction Designer defines how a user navigates through products, reacts to stimuli, and experiences the overall workflow. Utilizing advanced prototyping tools like Figma, Framer, and Principle, these designers craft meaningful motion patterns, state transitions, and responsive micro-interactions that elevate brand perception and ensure high-level usability across platforms.

What does a Interaction Designer do?

On a typical day, an Interaction Designer builds interactive prototypes to test complex user flows and gathers quantitative data from usability sessions to refine navigation logic. They collaborate with UI developers to hand off design specifications, ensuring that animations and component states are implemented exactly as envisioned. Beyond building screens, an Interaction Designer documents behavioral patterns, iterates on design systems, and conducts stakeholder reviews to align interactive elements with the company’s broader product strategy and technical constraints.

Key responsibilities

  • Design and document high-fidelity interactive prototypes using Figma or Protopie to communicate complex user journeys to cross-functional engineering teams.
  • Define clear motion design guidelines and animation states that enhance feedback and accessibility within our primary web and mobile product suites.
  • Conduct iterative usability testing sessions to identify friction points and validate interaction models against established user behavior metrics.
  • Collaborate with UI developers during the technical hand-off phase to ensure complex transitions meet performance requirements and accessibility standards.
  • Maintain and scale the organization’s design system, focusing on interaction patterns that ensure consistency across all product modules and touchpoints.
  • Analyze user session data and heatmaps from tools like Hotjar or FullStory to optimize existing click-paths and conversion funnels iteratively.
  • Lead design workshops and design-critique sessions to align stakeholders on the logic, flow, and intent behind proposed interface interactions.
  • Stay abreast of emerging HCI (Human-Computer Interaction) trends and accessibility legislation to ensure designs remain compliant with WCAG 2.1 guidelines.

Requirements and skills

  • 3+ years of experience as an Interaction Designer, Product Designer, or UX Designer with a strong portfolio showcasing complex digital flows.
  • Advanced proficiency in industry-standard prototyping tools including Figma, Protopie, or Framer with a focus on component-based design.
  • Deep understanding of Human-Computer Interaction (HCI) principles, cognitive load theory, and their direct application to interface design.
  • Expertise in designing for responsive layouts and mobile-first environments, with a practical understanding of CSS, HTML, and browser limitations.
  • Familiarity with accessibility standards (WCAG 2.1/2.2) and the ability to implement screen-reader-friendly navigation patterns and focus states.
  • Bachelor’s degree in Interaction Design, Human-Computer Interaction, Graphic Design, or equivalent professional certification (e.g., Nielsen Norman Group).
  • Proven experience working within Agile/Scrum development environments and participating in daily stand-ups and collaborative sprint planning.
  • Ability to articulate design rationale and present complex architectural decisions to non-technical stakeholders and leadership executives clearly.

FAQs

What does an Interaction Designer do on a daily basis?

An Interaction Designer focuses on the dynamic aspects of an interface, translating static wireframes into interactive prototypes that demonstrate how a user moves through a product. Their daily work involves creating micro-interactions, defining hover states and transitions, and testing these designs for usability. They spend significant time collaborating with software developers to ensure that these complex design interactions are technically feasible and correctly implemented in the live build.

What skills are required for an Interaction Designer?

Successful Interaction Designers possess a blend of technical design skills and psychological understanding. Essential tools include Figma, Protopie, and Principle, alongside a solid grasp of HTML and CSS to understand the frontend development process. Beyond software, they must demonstrate expertise in user research, wireframing, motion design, and accessibility compliance, paired with the ability to communicate how a design choice solves a specific user problem.

Who does an Interaction Designer work with in a tech company?

An Interaction Designer acts as a bridge between the creative and technical teams. They work most closely with UI designers to maintain a consistent visual language, while partnering with UX researchers to gather insights. They also maintain a daily feedback loop with frontend engineers to ensure that animation assets and interaction logic are performant and that design systems are implemented accurately within the final product code.

Why is the role of an Interaction Designer important for user experience?

An Interaction Designer is vital because they transform a product from a static set of pages into a cohesive, intuitive experience. By focusing on how a user feels and reacts to each click, swipe, or transition, they directly influence retention and customer satisfaction. High-quality interaction design reduces cognitive load, minimizes user errors, and creates a sense of polished professionalism that distinguishes leading products from their competitors.
