• Be the internal go-to person for all Modjo Academy questions.
• Organize team lunches, afterworks, and social moments at the office.
• Coordinate our annual seminars end to end: logistics, venue, program, and vendors (next offsite planned for September).

Description du poste

Our mission

The system is broken.

Sales should be an art built on human relationships and strategy. Instead, it has become a bureaucratic science. The best sales talent gets turned into accountants, buried under admin, CRMs, and reporting.

At Modjo, we're here to break these chains and deeply transform the B2B sales profession.

If you want to build the product that will make salespeople unstoppable and help redefine an entire industry: welcome aboard.

Our culture

Aim for excellence

We place particular importance on quality: in our product, our decisions, and the people we hire.

"Good enough" isn't good enough for us. We constantly push to improve, sharpen our thinking, and raise the bar even higher.

Team spirit and honest feedback

We believe great teams are built on trust, transparency, and collaboration.

Feedback isn't optional: it's an essential driver of collective and individual growth.

Users first

Everything we build starts from real-world realities and the concrete needs of sales teams.

We focus on solving real user problems, not theoretical ones.

Entrepreneurial spirit

We act like owners.

We don't wait for all the conditions to be perfect before moving forward. Autonomy goes hand in hand with responsibility.
