Senior Customer Success Manager (F/M)

In just a few years, we’ve grown to several millions in ARR supporting 180+ customers in France and across Europe in their procurement journey, growing the team to 60+ people (including remote employees).

Following a successful Seed funding round and a Series A of €15 million led by 13Books, Portage and Tomcat, we are focused on continuing our growth and expanding our impact in the market.

We have the ambition of being the leading procurement solution in France, and Europe. Our goal is to become the strategic partner for businesses, their Architect of Trust.Your role

You'll own a focused portfolio of high-value Enterprise accounts where the stakes are high, the stakeholder map is complex, and the margin for error is low.

The challenge is clear: What keeps Enterprise clients is not the product alone, it's the depth of the relationship, the quality of the strategic advice, and your ability to position Najar as an indispensable partner in how the company runs its procurement function.

You'll navigate C-level relationships, organizational politics, and high-ARR renewals.

You'll coordinate a binomial with a Procurement Expert who manages supplier negotiations on behalf of your clients.

And beyond your portfolio, you'll be expected to shape how the CS practice is built through playbooks, standards, and mentoring junior team members.

What you'll own :

Build and execute tailored account strategies: expansion plans, risk mitigation plans, multi-year roadmaps,
