Your goal: make sure our international clients are happy, their operations run smoothly, and OneFlash becomes an essential service for their visitors.

You’ll join the Ops & Customer Success team, working closely with our COO and international partners.

Your responsibilities:

• Manage and support a portfolio of international B2B clients (shopping malls, airports, events, leisure venues, etc.).

• Handle daily client requests (reporting, on-site operations, small logistics follow-up) and ensure proper communication with the Ops team in France.

• Track performance metrics and usage data, turning insights into actionable recommendations.

• Build and share monthly dashboards and performance reports for clients.

• Identify opportunities for upsell or renewal, and contribute to account plans.

• Coordinate on-site client activations, events, or trade fairs — possibly travelling in Europe to represent OneFlash.

• Contribute to improving internal tools, documentation, and customer processes.

• You’re currently in Master 1 or Master 2 (business school, university, or equivalent).

• You’re looking for a 6-month full-time internship starting January 2026.

• You have a first experience in customer success, account management, or operations.

• You’re fluent in English (mandatory – you’ll work daily in English).

• You speak Spanish (ideally), or German / Swedish as a strong plus.

• French is optional but appreciated for daily team interactions.

• You’re autonomous, structured, and proactive — capable of juggling multiple priorities.

• You have great communication skills and empathy, and love building long-term relationships.

• You’re comfortable with digital tools (Excel, Notion, HubSpot/CRM, etc.).

• You’re curious, resourceful, and want to grow in a fast-moving, international startup environment.

Pourquoi nous rejoindre ?

• Be part of a young, ambitious, and international team of 30 people.

• Get real responsibilities from day one — and make a visible impact.

• Work at Station F, the world’s biggest startup campus, in the heart of Paris.

• Join a company expanding fast across Europe with opportunities to travel.

• Enjoy regular team lunches, afterworks, events, and learning sessions.
