About The Position

FocusKPI is seeking a UX Designer - Bixby/Interaction Designer (AI Systems) to join one of our clients, a high-tech SaaS company. The Client's Advanced Intelligence Lab is seeking an Interaction Designer (AI Systems) to drive the next evolution of Bixby, the client's intelligent personal assistant. This role focuses on designing intuitive, high-quality AI interfaces that enhance user experiences and bring Bixby closer to becoming the primary entry point for interacting with products across the client's ecosystem – from mobile and wearable devices to TVs and smart home appliances. As an Interaction Designer, you'll bring AI strategy and product direction to life through visual design, interaction design, prototyping, and storytelling. You'll contribute to projects across the design lifecycle – from early concepts through launch and iteration – translating product requirements into clear, well-crafted interfaces. You'll work closely with other designers, product management, engineering, NLU, and research teams, as well as their design partners in Korea, to deliver experiences that are user-centered, technically feasible, and cohesive across surfaces. They’re looking for a designer with a high bar for craft – someone who thinks in states, behaviors, and systems, and enjoys turning complex AI interactions into clear, well-designed interfaces. This role emphasizes execution, prototyping, and polish over product ownership.

Requirements

Bachelor’s Degree or Master’s Degree preferred in visual design, HCI, computer science, or a related field – or equivalent experience.
3+ years of experience in visual or interaction design within product or UX teams.
Experience contributing to design systems.
This role seeks a detail-oriented designer who combines strong craft with thoughtful problem-solving to create intuitive, user-focused experiences.
User-centered expertise: Strong understanding of user behaviors and interaction patterns, with the ability to design intuitive, effective experiences.
Visual interaction design: Proven ability to design high-quality interfaces with attention to hierarchy, layout, and consistency. Experience working within and contributing to design systems.
Prototyping and innovation: Ability to rapidly prototype interactions and flows, test ideas, and refine solutions based on feedback and real-world constraints, bringing bold ideas and user scenarios to life.
Interaction thinking for AI systems: Experience designing for dynamic states, such as loading, ambiguity, errors, and multi-step or asynchronous interactions.
HCI & research awareness: Familiarity with human-computer interaction principles and the ability to incorporate user insights into design decisions.
Collaboration and communication: Ability to clearly present design work, articulate decisions, and partner effectively with leadership and cross-functional stakeholders.
Strong design portfolio demonstrating the best of your craft.

Nice To Haves

Expertise in Figma or similar design and prototyping tools.
Experience designing for AI-powered products or systems.
Familiarity with incorporating AI tools into design workflows.

Responsibilities

Drive end-to-end execution of UI and interaction design. Produce high-fidelity, production-ready designs for AI-powered features across mobile and multi-device experiences, with a strong emphasis on visual quality, interaction detail, and polish.
Prototype interactions, not just screens. Build visual and interactive prototypes that demonstrate flows, states, transitions, and edge cases, enabling rapid iteration and alignment with product and engineering.
Design for real system behavior. Account for loading, errors, ambiguity, partial results, and asynchronous states common in AI-powered experiences.
Translate defined product directions into concrete design solutions. Take clear requirements and turn them into thoughtful flows, interaction patterns, and refined user interfaces.
Work within and extend design systems. Use existing components effectively and evolve where necessary, ensuring consistency and scalability across surfaces.
Collaborate closely with cross-functional partners. Work with designers, product managers, and engineers to refine and iterate designs, provide specs, support implementation, and ensure high-quality execution.
Communicate work with clarity and precision. Present designs with a clear rationale, focusing on interaction decisions and tradeoffs rather than broad product strategy.
