About Lineshift

At Lineshift, we're building the next generation of customer operations, powered by AI.

Our AI agents handle phone calls, engage with customers via SMS and WhatsApp, book appointments, and take action directly within business systems.

Already deployed across automotive dealership groups and enterprise networks handling thousands of customer interactions every day, our technology helps companies boost productivity, improve customer experience, and drive revenue.

We're a fast-growing startup, profitable from day one, and proudly selected as one of STATION F's Future 40.

We're looking for a Customer Success Manager to help our customers get the most out of Lineshift, drive adoption, and grow their accounts.

Your Mission

Turn every Lineshift customer into a success story.

You'll own the customer journey after the sale, from onboarding and deployment to ongoing optimization, retention, and account expansion.

You'll work closely with our Sales and Solutions Engineering teams, combining relationship management, technology, and business impact.

What You'll Do

1. Customer Onboarding & Deployment

• Take ownership of new customers after the Sales handoff.

• Lead onboarding projects: understand business needs, coordinate stakeholders, and drive successful launches.

• Partner with Solutions Engineers to configure, test, and deploy AI agents.

• Train customer teams and ensure smooth adoption.

• Deliver a fast time-to-value and an outstanding first experience.

2. Performance Monitoring & Reporting

• Track key performance indicators: call volumes, resolution rates, appointments booked, leads captured, customer satisfaction, and ROI.

• Build and present regular performance reports and business reviews.

• Translate usage data into actionable recommendations.

• Demonstrate the measurable business value Lineshift delivers.

3. Continuous Optimization & Adoption

• Analyze conversations, workflows, and customer journeys to identify improvement opportunities.

• Work with Solutions Engineers to continuously improve AI agent performance.

• Use AI tools and automations to streamline customer reporting, monitoring, and follow-ups.

• Proactively recommend new features, automations, and use cases.

• Anticipate customer needs and resolve issues before they become problems.

• Drive product adoption and customer satisfaction.

4. Account Growth & Expansion

• Build trusted, long-term relationships with decision-makers and operational teams, particularly within automotive dealership groups.

• Identify upsell and cross-sell opportunities: additional locations, new use cases, and new communication channels.

• Partner with Sales to turn expansion opportunities into revenue.

• Manage renewals, reduce churn, and grow recurring revenue from existing accounts.

• Turn happy customers into advocates and references.

Why Join Lineshift?

• Real, measurable impact: Work on a product that delivers tangible ROI for customers.

• AI at the forefront: Help businesses adopt technology that's fundamentally transforming their operations.

• Ownership from day one: Play a key role in building and scaling our Customer Success function.

• Work AI-native: We don't just sell AI. We use it every day to automate our own workflows, move faster, and achieve more with a small team.

• Entrepreneurial culture: Small team, fast decisions, high autonomy, and minimal bureaucracy.

• Room to grow: As Lineshift scales, you'll have opportunities to take on greater responsibility and help shape the team.

How to Apply

Send us your CV or LinkedIn profile, along with a few lines about why you'd like to join Lineshift.

Bonus challenge: Tell us about an AI agent or automation you've built, what problem it solved, and how you approached it.

Our goal is simple: make every customer more successful with Lineshift, every month.

Preferred Experience

Who You Are

• 2–5 years of experience in Customer Success, Account Management, Project Management, or Consulting, ideally in B2B SaaS.

• AI-native mindset: You're already a proficient user of AI assistants and agents. You know how to leverage tools like ChatGPT, Claude, or similar platforms to get real work done, not just generate text.

• Hands-on automation skills: You've built workflows or automations using tools such as n8n, Make, Zapier, or AI agent platforms. You're comfortable connecting tools, working with structured data, and automating repetitive processes.

• Technical curiosity and autonomy: You enjoy experimenting with new AI tools, troubleshooting workflows, and finding creative solutions without always relying on engineering.

• Excellent communication skills: You're equally comfortable speaking with C-level executives and frontline operational teams.

• Commercial mindset: You understand ROI, customer retention, and account growth.

• Analytical and data-driven: You enjoy working with KPIs, dashboards, and performance reports.

• Highly organized and proactive: You can manage multiple customers and projects simultaneously.

• Fluent in both French and English, written and spoken.

Bonus points if you have:

• Experience in the automotive industry, particularly with dealership groups, aftersales operations, or automotive retail.

• Experience in SaaS, telephony, CRM, or conversational AI.

• Experience managing enterprise or multi-location customers.

• Familiarity with APIs, webhooks, CRM integrations, or no-code/low-code platforms.

• A track record of driving account expansion and renewals.

• A builder mindset: you love creating processes, experimenting, and improving how things work.
