Location: Paris, France
Contract: Part-time (4 days/week)
Start date: As soon as possible

Your Role:

At LaSource, we help sports organisations, entertainment companies, and innovative startups unlock the power of technology and data. Our team combines strategic expertise and hands-on delivery to support clients globally. We are a dynamic, international, and growing company that values innovation, ownership, and collaboration.

About Us:

As Office Manager, you’ll be at the heart of the company, ensuring that everything runs smoothly behind the scenes while also being a visible touchpoint for some of our clients and partners. From managing admin and finance processes to supporting HR and team operations, you’ll create the structure that enables our consultants and partners to focus on delivering impact.

Beyond internal support, you’ll also interact with clients: coordinating invoices, handling event organisation, and occasionally representing LaSource in day-to-day communications. You will report directly to one of the Partners and work closely with our finance and operations support team.

What you will do:

  • Internal Operations and team support

    • Keep the office running smoothly: supplies, logistics, communication with providers.

    • Organise and maintain contracts and company documents.

    • Support HR processes: onboarding new team members, contracts, payroll liaison, leave tracking.

    • Help improve and implement internal processes and tools for efficiency.

  • Administrative & Financial Tasks

    • Prepare invoices, follow up on payments, and act as a point of contact for client finance teams.

    • Support basic bookkeeping and liaise with our accounting provider.

    • Manage supplier contracts, expense reporting, subscriptions, and administrative documentation.

  • Client-facing support & events

    • Coordinate event logistics (venues, travel, suppliers) for client travel and internal events.

    • Assist management with reporting and follow-up tasks when needed.

Profile We Are Looking For 

  • Previous experience in office management, admin support, or executive assistance.

  • Organised, detail-oriented, and proactive: you make sure nothing slips through the cracks.

  • Comfort with administrative tools (Google Workspace, basic accounting/CRM software).

  • Confident handling of numbers, invoices, and financial processes.

  • Excellent communication skills in both English and French (written and spoken).

  • Reliable, flexible, and able to work independently in a fast-paced, entrepreneurial environment.

What We Offer:

  • Competitive salary based on experience and aligned with market benchmarks.

  • 4-day work week (part-time contract).

  • Usual benefits: meal vouchers, health insurance, team events, etc.

  • A dynamic, international work environment with flexibility and autonomy.

  • The opportunity to grow with a company at the intersection of sports, entertainment, and technology.

  • The opportunity to take on more operations, HR, or finance responsibility as the company grows.
