About White Circle
White Circle provides real-time protection for LLM-powered products by intercepting harmful prompts and unsafe model outputs before they reach the user, with analytics and monitoring on top. They work with companies like Lovable and Dust.
The team is 16 people in Paris, engineering-driven, preparing for Series A. The culture is fast, a little chaotic, and deeply technical, but that doesn't mean you'll be on your own. You'll work directly with the Head of Design, who sets priorities, gives feedback, and is your day-to-day partner. No layers of review, no endless alignment meetings, just a short loop between discussion, design, and production.
Most AI safety and observability tools have interfaces that only engineers love. White Circle believes it's possible to make this space clean, intuitive, and even elegant. That's the challenge.
What You'll Be Responsible For
- Build the design system from scratch. There isn't really one yet, and it's a key bottleneck. Once the foundation is set, you'll shift toward product work.
- Design product features: analytics dashboards, policy configuration forms, tracing views, and settings pages. Classic B2B SaaS, web only.
- Make complex things simple. The users today are AI researchers and safety engineers, but the product is heading toward a broader audience. Every interface should work for both.
- Write clear task descriptions in Linear, so engineers know exactly what to build and why. Good writing matters here as much as good design.
- Bring design perspective to the table early by contributing to product discussions with engineers when features are being shaped.
- Own UX copy on your screens, such as labels, tooltips, empty states, and error messages. Every word should be intentional.
What You'll Need to Succeed
- A portfolio with real UX depth: forms, dashboards, data-heavy interfaces, B2B/SaaS products. The team will look at how you think through complexity, not just how things look.
- Experience building or meaningfully contributing to a design system, not just using one.
- Basic understanding of frontend development: responsive layouts, component thinking. You don't need to code, but you should know what's realistic.
- Strong English writing. Your Linear tickets, your UI copy, your Slack messages — they all need to be clear and well-structured.
- Self-sufficiency. You take a task, dig into it, ask questions early (not after you've gone down the wrong path for a week), and come back with something thoughtful. The team has limited bandwidth for mentoring, so it’s worth being honest about that.
- Comfort with direct feedback. The team will tell you when something isn't working. It's about the work, never personal. They need someone who sees that as useful, not threatening.
- Genuine curiosity about the product. "What does this feature actually do for the user?" should be a question you ask before you open Figma.
Huge Plus If You Have
- Experience with AI products, developer tools, or technical infrastructure.
- Familiarity with v0.dev, Cursor, or similar AI-assisted design/dev tools.
- A habit of researching competitors, collecting references, and bringing ideas to design reviews without being asked.
- Interest in AI safety, LLM evaluation, or the broader AI tooling space.
What You'll Win
- Equity in a pre-Series A company that already has paying enterprise clients.
- CDI — a permanent contract under French law, after a 1-month paid trial.
- Salary reviewed and increased at each funding round.
- Relocation to Paris in roughly 2 weeks, as France's innovation visa program makes this straightforward.
- A two-floor office in central Paris. Attendance is flexible: show up when collaboration matters, work from home when you're in the zone.
- Direct work with the Head of Design. No PMs translating requirements, no design committees. You discuss, you design, you ship.
What's Great About This Role
Here's what's unusual about this position: you're not inheriting a design system and maintaining it. You're building one. At a company where the product is already used by some of the most technically demanding teams in AI.
The problem itself keeps getting more interesting. AI outputs are getting harder to evaluate, harder to trust, harder to monitor. The interfaces that make this manageable don't exist yet. You'd be designing them.
