Founding Product Designer
About The Position
We're on a mission to make subscriber churn a solved problem. Backed by a16z Speedrun, we build AI agents that help consumer subscription brands — like Higgsfield and Promova — retain more users, extend lifetime value, and grow fast. We're an incredibly driven team working on a problem that affects every consumer on the planet. If that sounds like your kind of thing, we'd love to meet you. Our co-founders are Azamat Khamidov and Benazir Toleubekova. Azamat built a Telegram AI product from zero to five million users in four months, the first acquisition inside Telegram. Benazir received a full scholarship to Beijing University of Technology at 15. Joined Taobao at 17. At Alibaba, architected the core recommendation engine serving 500M daily users. 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.
Requirements
- 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.
Responsibilities
- 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
Benefits
- Flexible healthcare: We offer flexible spending to direct your benefits toward what matters most to you and your family.
- 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.
