TLDR: We’re looking for a highly organised and resourceful Personal Assistant. This is a hands-on execution role focused on taking ownership of administrative, logistical, and personal tasks: from calendar and travel coordination to paperwork, appointments, and everyday errands. This is not a strategy or business-partner role: success means handling the details reliably, quickly, and with minimal supervision.

About us

White Circle is an AI Safety company building the safety, reliability, and optimization layer for AI systems. At the core of our platform are policies – simple natural-language rules that define what an AI model should and shouldn’t do. We automatically test, enforce, and continuously improve these policies at scale.

• We’ve raised $11M from top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others

• We process over one hundred million API calls every month

• We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model

We’re a small, highly focused team. If you want to work deeply on hard problems, see your work ship to production quickly, and influence how AI safety is actually built – you’re the one we need.

You will:

• Coordinate meetings, calendars, and inboxes

• Handle travel planning (flights, hotels, logistics)

• Research and compare services, products, etc.

• Book reservations, appointments, and meetings

• Handle operational and administrative tasks quickly and independently

• Organise information and summarise options clearly

• Help reduce day-to-day operational friction across a wide variety of areas

You’ll fit right in if you:

• Have fluent English and French (both are mandatory)

• Are highly responsive and reliable

• Are comfortable with ambiguity and fast-changing priorities

• Can make decisions independently without needing detailed instructions

• Communicate clearly and concisely

• Are highly organised and detail-oriented

• Are proactive, resourceful, and naturally “figure things out”

• Are comfortable working async and occasionally across unusual hours/time zones

A big plus:

• Experience supporting founders, executives, creators, or startup teams

• Familiarity with AI tools and productivity software

• Experience working remotely in fast-moving online environments

Why White Circle

• Paid time off in line with your local regulations, no matter where you work from

• Best medical insurance in France

• All the hardware, tools, and services you need

• Covered subscriptions for AI agents

• Team off-sites twice a year: we’ve recently been to the Alps and to Saint-Tropez
