Sr. AI UX Designer & Prompt Architect

At AbsenceSoft, we’re transforming the employee experience. Our secure, intuitive technology helps employers bring humanity, certainty, and efficiency to some of the most complex moments in the workplace. Built by HR professionals for HR professionals, we’re proud of where we’ve been and even more excited about where we’re going.

We’re seeking a Senior AI Experience Designer & Prompt Architect to shape the future of intelligent, conversational, and assistive applications. This role blends UX design with AI interaction architecture, focusing on crafting intuitive, aligned, and trustworthy experiences where the prompt itself becomes the interface. You’ll work at the intersection of design, user psychology, and AI system behavior—defining how users engage with intelligent systems through thoughtful, human-centered design.

What you'll do

• Design user experiences that incorporate natural language interactions with LLMs and agentic systems, focusing on usability, clarity, and alignment.
• Conduct user research, persona development, and journey mapping to identify user needs and opportunities for intelligent automation.
• Craft, iterate, and test prompts that guide AI behavior—including tone, style, instruction strategy, few-shot examples, and function/tool usage.
• Prototype AI interactions using prompt libraries, sandbox environments, and conversational UI flows.
• Build prompt evaluation protocols including hallucination detection, instruction following, response quality, and consistency.
• Apply techniques such as chain-of-thought prompting, ReAct, self-reflection, tool-chaining, and autonomous prompt loops.
• Collaborate with Product, Engineering, Data Science, and Compliance teams to align experience goals with technical feasibility and regulations.
• Design for multi-modal interfaces (text, audio, visual), ensuring accessibility across diverse user types.
• Define the experience layer of intelligent systems, including fallback logic, transparency, user agency, and correction loops.
• Serve as the creative force behind scalable AI interaction frameworks for internal tools and customer-facing applications.

What you'll bring

• 6+ years of experience in UX design, UX research, conversational or AI interaction design.
• A strong portfolio demonstrating complex systems design with elegant, user-centered interaction patterns.
• Deep understanding of UX research methods, design thinking, usability testing, and accessibility principles.
• Hands-on experience designing and testing prompts for LLMs (OpenAI, Claude, etc.), including multi-turn and tool-using agents.
• Working knowledge of prompt engineering best practices: instruction design, context control, chaining, grounding, and temperature tuning.
• Experience with experimentation and prompt evaluation methodologies (A/B testing, RLHF-style evaluation, bias detection, telemetry feedback).
• Understanding of how LLMs work, including transformer behavior, tokenization, and limitations.
• Strong written and visual communication skills with an eye for tone, microcopy, and behavioral nudges.
• Empathy for end users and a commitment to building transparent, safe, and trustworthy AI systems.
