Customer Success Manager

About Siesta AI

We are building Siesta AI, a Czech AI startup with the ambition to succeed across Europe. Our customers in energy, manufacturing, logistics, aerospace and real estate run real processes on our platform, in the Czech Republic and abroad.

Signing a contract is where the real work starts. A customer has data, people and processes, and somebody has to make sure the platform ends up in their daily work rather than in a pilot nobody opens. We are looking for that somebody.

You are the person our customers call. You run their onboarding, you know how they use the platform, you turn their requests into clear work for product and delivery, and you find the next process worth building. You are technical enough to set things up yourself and client-minded enough to pick up the phone when something is wrong.

We are not looking for someone who forwards tickets. We are looking for someone who wants to own a portfolio of enterprise customers while the company is still small enough for one person to shape how customer success works here.

What you will do

• Run onboarding for new customers: environment, first use cases, training the people who will use it.
• Stay in regular contact with your customers, follow how they use the platform and where it brings value.
• Turn customer requests into clear assignments for product and delivery and make sure they get done.
• Make the smaller changes yourself: an agent, a workflow, a prompt, a new data source.
• Work with the Product Specialist on the larger use cases and bring the customer's view into them.
• Watch satisfaction, adoption and renewal for every account, and act before a problem becomes a churn conversation.
• Find the next use case at an existing customer and hand it over to the business team as a real opportunity.
• Feed what customers say back into the product roadmap and into how we onboard the next one.

No two customers are alike

Different company, different people, different pace. In one month you might:

AI has to be a normal working tool for you

We are an AI company, so we do not want to explain to anyone why ChatGPT or Claude is useful. You do not need to code. You do need to be comfortable setting up the platform yourself, showing it to a customer and understanding what AI can and cannot do for them, so that you hand over a solution rather than a ticket. And we expect that you already use AI in your own work every day.

Who we are looking for

• You enjoy long-term relationships with customers and take their problems personally.
• You are technical enough to configure a tool like ours yourself and explain it to others.
• You use AI tools every day and understand what companies can realistically expect from them.
• You speak and write clearly, with management and with people on the shop floor alike.
• You can handle several customers at once without letting anything slip.
• You notice when something is quietly going wrong and act before the customer has to say it.
• You have a natural interest in business, technology and AI.
• You finish things and do not need ten reminders.
• You want to grow faster than a classic career path allows.

Experience in account management, customer success, consulting or SaaS implementation is an advantage, not a condition. How you have looked after customers matters more to us than the job titles on your CV.

What we offer

• Full-time work directly in an AI startup.
• Direct cooperation with the leadership of the company.
• Your own large Czech and international clients.
• The chance to learn how an enterprise AI product is deployed and adopted in practice.
• Fast professional growth based on results and the responsibility you take on.
• A young team and a minimum of corporate nonsense.
• Team lunches every Wednesday.
• A pet-friendly office.
• A discounted Multisport card.
• Stays at our guesthouse in the Jizera Mountains.
• An office at Bruselska 14 in Prague Vinohrady.

In practice

• Full-time.
• Prague office 3 days a week, 2 days remote.
• Cooperation as a contractor or another agreed form.
• Start by agreement, ideally as soon as possible.

Want to go for it?

Send us your CV and a few sentences about yourself. What we mainly want to know:

• Describe a customer you kept or grew, and what you did for it.
• How do you use ChatGPT, Claude or other AI tools in your work today?
