Job description

About Us:

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.

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.
