Full Job Description
What You'll Do:

This is the first design role at Sirius. That means you'll set the visual and interaction language for everything we build. We're looking for a Product Designer who cares about the craft at every level; from the shape of an interaction to the clarity of a data visualization. You'll be working on a product that touches real revenue for real companies, which means your design decisions matter in ways you'll be able to see and measure. You'll be a close partner to engineering and product, shaping how we communicate complex retention intelligence in ways that feel obvious and inevitable to the people using it.

  • Own product design end to end - research, flows, high-fidelity UI, and the handoff details that make implementation feel right
  • Build and maintain a design system with a long-term sensibility, not just the current sprint
  • Work directly with Claude Code and TypeScript to prototype and occasionally contribute production-ready UI
  • Partner with founders on product direction, bringing a designer's perspective to strategy early - not just execution
  • Move fast enough to keep pace with a small team, but carefully enough that the quality standard stays high


What You'll Bring:

  • 3+ years of product design experience - enough that you've shipped something real and learned from what didn't land
  • Figma fluency: components, variables, auto-layout, prototyping
  • Comfortable using Claude Code/Codex to accelerate your workflow and iterate on live UI
  • TypeScript literacy - you don't need to be an engineer, but you can read and write enough to collaborate without a translator
  • A portfolio that shows taste, rigor, and the ability to simplify complex problems into clear interfaces
  • Based in San Francisco or able to be here full-time. We're not offering visa sponsorship at this time.


Our Values:

Stewardship: We build for the long term. Every customer, partner, and teammate gets that same commitment from day one.

Trust: Earned through the integrity of our technology, the consistency of our commitments, and the honesty of our communication.

Customer Obsession: We win when our customers win. Every choice and conversation orbits around what makes them stronger.

Excellence: The same standard for the product we ship, the service we give, and the team we build. The bar is the bar.

Family: A constellation, not a single star. We back each other on hard days, celebrate the great ones, and protect the time teammates need to be parents, partners, and humans first.

Life at Sirius:

In-person, in San Francisco: We work side by side, on-site in San Francisco. Proximity helps us move faster, solve harder problems, and build something we're proud of together. Note: we're not able to offer visa sponsorship at this time.

Flexible healthcare: We offer flexible spending to direct your benefits toward what matters most to you and your family.

Own what you build: We're building something real, and we want you to own it.

Lunch, coffee & snacks: Daily lunch, plus coffee, tea, and snacks to keep you going.

Time off that's actually off: Take the time you need to show up as your best self. We mean it.

Company Events: We work hard and celebrate our wins.
