Executive Assistant

TLDR: We’re looking for an Executive Assistant to help handle operational and personal logistics in a fast-moving, highly async environment. You’ll own scheduling, travel coordination, research, sourcing, bookings, and a wide range of day-to-day operational tasks.

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

• Work from Paris (hybrid) + relocation package

• 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
