Product Designer (UX), HCI

BJAK is hiring a Product Designer specializing in UX and HCI. The role focuses on designing human-AI interaction models and end-to-end experiences that help users understand, guide, correct, and trust AI systems. Responsibilities include creating prototypes, conducting usability research, and collaborating with product, engineering, and ML teams to ship reliable AI product experiences.

Responsibilities:

• Design end-to-end user experiences for AI product surfaces, from concept to shipped product
• Create interaction patterns for human-AI workflows, including prompting, review, confirmation, correction, handoff, and recovery
• Design interfaces that help users understand what the AI is doing, what it knows, what it is unsure about, and what will happen next
• Turn complex, multi-step AI capabilities into flows that are clear, controllable, and usable in everyday contexts
• Work closely with product, engineering, and ML teams to define problems, test ideas, and ship quickly
• Produce wireframes, flows, prototypes, and high-fidelity designs for web and mobile
• Run lightweight user research and usability tests to identify friction, trust issues, and failure points
• Help define reusable HCI design patterns as the product and design system mature

Requirements:

• • Experience as a product designer or UX designer, with a portfolio across web or mobile products
• • Strong skills in interaction design, information hierarchy, and prototyping
• • Proficiency in Figma and fast iteration workflows
• • Ability to simplify complex systems and turn unclear product behavior into clear user experiences
• • Experience working closely with product managers and engineers in fast-moving teams
• • Comfort working with ambiguity and shaping solutions before requirements are fully defined
• • Good judgment on usability, edge cases, and failure handling
• • Clear thinking about trust, control, feedback, and transparency in AI-driven experiences
