The opportunity

Own the accounts. Drive the outcomes.

Atiom closes the gap between brand promise and customer experience — the performance platform that gets frontline teams prepared, practised and performing. Customer success is how that promise is kept: the hands-on work of turning a signed contract into measurable behaviour change on the floor.

As a Senior Customer Success Manager, you'll own a portfolio of key accounts end to end — building the kind of trusted, consultative relationships that drive satisfaction, renewal and growth. You'll work closely with our Customer Success Director and act as a strategic partner to some of the world's most demanding service-first brands.

What you'll do

The role, in three parts.

Manage key accounts

Own day-to-day relationships across your portfolio — proactively managing health, responding to feedback, and ensuring every customer feels supported and heard. Lead regular business reviews that tie Atiom's impact to the outcomes clients care about.

Drive growth and expansion

Co-develop account plans and growth strategies tailored to each customer. Identify and execute opportunities for renewal, upsell and cross-sell — and act as a trusted advisor who translates Atiom's AI-powered behavioural insights into clear ROI narratives for executive stakeholders.

Lead and elevate

Lead onboarding of new key accounts, mentor junior Customer Success Managers, and feed customer intelligence back to Product and Engineering so the roadmap reflects real operational need.

What we're looking for

A senior partner who drives measurable impact.

5+ years in account management or customer success — ideally within SaaS, with a track record in renewals and expansion.
Service-first industry experience — hospitality, retail, travel or similar is strongly preferred.
Executive-level communication — you can influence senior stakeholders and build the kind of relationships that last.
Data-driven approach — you use analytics to track performance, identify trends and shape recommendations that clients act on.
Strategic and consultative — you think in account plans and outcomes, not just tickets and tasks.
Mentoring experience — you've supported junior team members and helped raise the standard around you.
Fluent English — written and spoken; additional languages a plus.

What success looks like

In your first year.

Key accounts retaining and expanding — customers who feel genuinely partnered, not just managed.
AI insights landing as clear ROI stories that executives understand and act on.
A junior CS team that is better for having worked alongside you.

About Atiom

A category, being defined.

We've been closing the gap between standards and service since 2020. Atiom builds behaviour-change technology used by some of the world's most demanding service-first brands — and we work alongside them, so the roadmap comes from real operations, not a whiteboard.

The team is senior, the customers are global, and the ownership is real. What you build — or sell — reaches the floor.
