Senior Product Designer, AI

About the role

Sigma is transforming how businesses allow customers to build apps, agents and dashboards on top of governed enterprise data. We are growing the design team and are seeking a Senior Product Designer / Design Engineer who sits at the intersection of interaction design and AI engineering.

Responsibilities

• Start with AI, stay with AI. Use LLMs to clarify scope, draft specs, surface edge cases, and align your team before committing to a direction. Use AI coding tools to build and iterate on the solution itself, and merge code to prod when fits.
• Prototype in code. Build working interfaces with Cursor and Claude Code, guiding structure, behavior, interaction, motion and UX quality while AI handles implementation.
• Partner directly with engineering to decide what moves into the product and what stays as a validated spike.
• Bring it to production. Fix small interaction and refinement issues directly on prod code.
• Design new AI interaction paradigms for conversational interfaces. Invent and validate novel patterns for how users converse with, direct, and trust AI systems - especially in data contexts where precision and confidence matter.
• Write evals, agents, prompt libraries, or skills for AI systems. You understand why evaluation is the hardest part of AI product development.
• Strong interaction design fundamentals: you know when to reach for a new pattern and when to extend a familiar one, and you can defend that choice to anyone.
• Opinions about AI UX: trust signals, error recovery, progressive disclosure of reasoning and real examples of how you've addressed these.
• Exceptional ability to communicate design decisions to PMs, engineers, ML researchers, and executives.
• Portfolio that includes AI-powered or AI-adjacent product work. Bonus if includes conversational interfaces.

Requirements

4+ years in interaction design or design engineering, with recent hands-on AI tooling experience — not just prompting, but building. Demonstrated use of AI coding assistants to ship real product (and side projects). Experience writing evals, agents, prompt libraries, or skills for AI systems. Strong interaction design fundamentals. Exceptional ability to communicate design decisions to PMs, engineers, ML researchers, and executives. A portfolio that includes AI-powered or AI-adjacent product work.

Qualifications

We want to see designs that have been successfully released that demonstrate system-wide thinking, breadth and depth in interactive design skills and AI first. We want to see your process and progressive evolution of your designs, including the business problem you were trying to solve, constraints and assumptions you needed to work within, where the design started and your significant iterations leading to the final product. We want to understand how your designs furthered company objectives while meeting user needs.

Skills

Knowledge of AI coding assistants, experience with LLMs, familiarity with Cursor and Claude Code, strong interaction design fundamentals, ability to write evals, agents, prompt libraries, or skills for AI systems, exceptional communication skills, and a portfolio demonstrating AI-powered or AI-adjacent product work.

Benefits

The base salary range for this position is $210,000 - $250,000 annually.
