About the role

Silmaril in San Francisco seeks a senior product designer to shape how people understand, trust, and interact with autonomous agents. You will lead product strategy, UX, UI, and brand, partnering with founders and engineers from research through prototype, production, and iteration. You will own design systems, typography, layout, and interaction details, ensuring an agent-first experience that is clear, usable, and delightful.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
