ABOUT GLADIA
Gladia builds the audio AI infrastructure behind the new generation of voice products. Our mission is to give every voice platform true conversational intelligence — the audio infrastructure that understands every conversation, turning voice into the world's most valuable data layer.
Our API turns real-world conversational audio into accurate, structured, real-time output — powered by our proprietary Solaria ASR, across 100+ languages, with industry-leading latency.
Hundreds of companies build their voice products on Gladia — from meeting assistants and voice agents to sales-enablement and contact-center platforms. We started in Paris, our growth is developer-led and heavily US-driven (and we're going after the US market hard).
Headquartered in vibrant tech hubs like Paris and New York City, Gladia has been acquired by OVH Groupe — Europe's leading cloud provider — and now operates as a fully autonomous brand and company within the Group.
We're guided by four values:
- Honest — Say the real thing, kindly.
- Smart — Work smart, ship fast.
- Builders — Own your scope, build to last.
- Caring — Support people, take pride in the craft.
THE ROLE
We're looking for a Senior Customer Success Manager to own the relationship with our most strategic customers and make sure they succeed at every step — from onboarding and integration to adoption and long-term value.
You'll be the main point of contact for our customers' technical and product teams, helping them understand, adopt, and scale with our API. The role is hands-on and cross-functional: you'll work closely with Sales, Support, Product, and Engineering to drive customer outcomes.
We're an API-first company, so we're looking for someone who thrives in a technical environment and is obsessed with customer value, satisfaction, and retention.
WHAT YOU'LL DO
BUILD A CUSTOMER SUCCESS STRUCTURE THAT WORKS
- Be our customers’ day-to-day point of contact and give them the support they need, when they need it
- Set up and improve our CS playbooks, onboarding flows, tooling, and metrics
OWN THE CUSTOMER LIFECYCLE
- Lead end-to-end onboarding for new accounts: setup, training, integration, and early activation
- Run regular check-ins with your customers, plus business reviews (QBRs) to show the value they get from Gladia
- Monitor usage and proactively support customers to drive adoption and remove friction
CATCH CHURN EARLY
- Build a system that surfaces early signs of churn (usage drops, health scores, support signals)
- Act on those signals quickly to keep customers healthy and satisfied
- Understand each customer’s goals and help them reach them faster with Gladia
BE THE CUSTOMER’S EARS INSIDE GLADIA
- Collect customer needs and feedback, and bring them to Product in a structured way to shape the roadmap
- Know our roadmap well and dig into it to give customers clear answers on what’s coming
- Become a trusted advisor to technical stakeholders, product leads, and executives
WHO YOU ARE
- 4–7+ years in Customer Success or Technical Account Management
- Previous experience with an API-first or developer-facing product
- Obsessed with customer satisfaction and retention: you spot risks before they happen, make sure customers get maximum value from the product, and build long-term, trust-based relationships
- You've managed a portfolio of strategic or enterprise customers and driven measurable value for them
- Excellent communicator — you know how to talk to developers, product managers, and executives
- Organized, autonomous, and process-driven — you're always two steps ahead
- Fluent English; French is a plus
