Description du poste

Mercateam is the platform manufacturers use to digitalize their industrial know-how (skills, certifications, training, workforce planning) and turn it into measurable operational performance on the shop floor. Every month, top industrial sites go live with us.

At Mercateam, the Customer Success Manager owns the account from the day the contract is signed until renewal. Sales signs, deployment configures. You hold the plan that turns a signed contract into proven operational results ready for expansion, and you mobilise the rest of the team to get there.

You’ll join a CS team of 3 CSMs, working closely with Sales and the deployment team consultants.

The role: Senior Customer Success Manager

You’ll own a portfolio of industrial groups, multi-site, with stakeholders from shop floor to group level. Your mission: make each client reach, and prove, the operational outcomes they bought Mercateam for.

What you’ll do

1. Own the account plan, from signature to renewal

• Join deployment on site at kick-off: map stakeholders, capture the KPI baseline to be able to prove ROI and prepare what comes next.

• Build and run a shared action plan per account: scope extension, new modules, integrations, external dependencies (HRIS, reorganisations, budget cycles). You keep owners and deadlines moving, on the client side and internally.

• Supervise deployment with the long-term view: assess the quality of what’s delivered and challenge set-up decisions that solve today’s need but won’t hold as the account grows (new sites, modules, use cases).

• Once the account is live, qualify each new client need and bring in the right people internally: deployment for configuration, product for a blocking limitation, our CEO for executive backing. You own the resulting timeline with the client.

2. Drive and prove value

• Define with each client where they want to go, show them the path, and prove progress against the baseline at regular checkpoints.

• Run steering committees: operational COPILs with site or BU champions, and strategic COPIL with the executive sponsor to present consolidated ROI.

• Turn results into customer stories clients are proud to share both internally and publicly.

3. Know your clients’ organisations inside out

• Map and maintain the operational network on each site: decision-maker, champion and backup, active managers, sources of resistance.

• Spot early warning signs (champion departure, usage drop, reorganisation…) and trigger the right response

4. Detect growth

• Surface expansion opportunities: uncovered sites or workshops, missing modules, latent needs. You frame the business problem and the product answer, involving sales on pricing and contract.

• Defend your accounts and their development plan at our internal quarterly business reviews, alongside the Account Executive.

5. Be the client’s voice in the product

• Keep a clear view of the product limitations blocking your accounts and what’s at stake, and feed it into roadmap decisions.

Why join us

• Real ownership: one account plan from signature to renewal, with the whole team (deployment, product, leadership) as resources you mobilise.

• Senior industrial stakeholders: plant directors, operations directors, group leadership.

• Measurable impact: your success is measured on your clients’ operational progress against a baseline you set yourself.

• Room to shape how Customer Success works.

• Travel to client sites in France and abroad, learn what manufacturing in France is, don’t just sit behind a desk.

How we take care of you

• Health insurance: Alan Purple, 100% covered for you

• Lunch: Swile meal vouchers

• Flexible remote

• Time off: RTT

• Team life: offices in central Paris (Montmartre), annual offsite, monthly afterworks after the All-Hands
