Interaction Designer, HCI at Bjak

The role

This role focuses on designing the detailed mechanics and HCI interaction patterns for a proactive AI smart assistant. You will define how users interact with, supervise, and maintain agency over complex AI-driven workflows.

What you'll do

• Design detailed interaction models for multi-step AI-driven tasks
• Define specific interaction states like thinking and waiting for AI interfaces
• Create human-in-the-loop controls for reviewing and overriding AI decisions
• Develop interaction patterns for delegation and recovery from AI errors
• Produce detailed interaction specifications and prototypes for engineering handoff
• Collaborate with ML teams to translate system constraints into usable patterns

What you'll bring

• Proven experience as an interaction designer or senior UX designer
• Strong prototyping skills using tools like Figma
• Ability to design micro-level states and handle non-deterministic system behavior
• Deep understanding of HCI principles including transparency and user control
• Systematic thinking to map complex AI logic into coherent user flows

Your impact

You will help define entirely new interaction patterns for proactive AI products from the ground up. By creating intuitive controls and feedback loops, you will ensure that users feel empowered and in control of their AI assistant rather than confused by its autonomous actions.
