Senior Product Designer, AI
Sigma Computing, San Francisco, CA, United States
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 looking for designers who are excited to solve challenging problems and deliver impactful capabilities across our stack.
This role is a Senior Product Designer / Design Engineer sitting at the intersection of interaction design and AI engineering. It is a 4‑day on‑site role in our San Francisco office.
What You’ll Do
Start 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 production when it 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 production 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 evaluation frameworks, skills, and tooling that make AI reliable—build the scaffolding that lets Sigma’s AI features behave predictably and improve over time.
Shape model behavior—iterate on evaluation and training to improve AI performance on design output; in other words: teach AI how to be a great designer.
Set the craft bar—define what great AI‑native UX looks like at Sigma: patterns and principles the broader team builds on.
What We’re Looking For
4+ years in interaction design or design engineering, with recent hands‑on AI tooling experience—building, not just prompting.
Demonstrated use of AI coding assistants to ship real product (and side projects); explain what was built, how AI accelerated it, and where you steered it.
Experience writing evaluation frameworks, agents, prompt libraries, or skills for AI systems; understand why evaluation is the hardest part of AI product development.
Strong interaction design fundamentals—know when to reach for a new pattern and when to extend a familiar one, and be able to defend that choice.
Opinions about AI UX: trust signals, error recovery, progressive disclosure of reasoning, and real examples of handling these.
Exceptional ability to communicate design decisions to PMs, engineers, ML researchers, and executives.
A portfolio that includes AI‑powered or AI‑adjacent product work.
Transformed intricate interaction problems into elegant flows; bonus if it includes conversational interfaces.
Demonstrated designs that have been successfully released, showing system‑wide thinking, breadth and depth in interactive design skills, and AI first approach.
Process documentation that shows business problem, constraints, assumptions, starting point, and significant iterations leading to the final product.
Demonstrated impact on company objectives while meeting user needs.
Base salary: $210,000 – $250,000 annually. Variable pay, stock options and a comprehensive benefits package are also offered.
