Quick summary: We’re looking for a proactive Customer Success Specialist who thrives in helping clients succeed from day one. You’ll be the first person new customers meet at Sintra, ensuring smooth onboarding, building trust, and laying the foundation for long-term client relationships. You enjoy creating structure, improving processes, and guiding SMB clients through a product with clarity and empathy.

‍

Why join Sintra?

We build AI employees for small businesses. Real helpers with personalities, not faceless chatbots. They handle the work that keeps owners up at night - answering customer emails, posting on social media, analyzing sales data. For business owners who've always worked alone, we're giving them their first team.

‍

50,000+ businesses use Sintra because for the first time someone made AI actually useful for them. While Silicon Valley builds for tech companies, we're building for the florist who needs help with Instagram, the contractor drowning in invoices, the restaurant owner who can't keep up with reviews.

‍

This is a unique moment in history. AI just became good enough to fundamentally change how small businesses operate. Behind every business is someone trying hard for their family. Someone with one goal - put food on the table. And our job is to help them succeed.

‍

Having just raised our $17M seed round, we're off to the races. Small, fast-moving team building together in person. We ship daily, take ownership of what we build, and live by one principle - work is play.

‍

What you'll do

• Lead onboarding for new SMB clients through structured video calls
• Build and refine onboarding processes and playbooks as the team grows
• Guide clients through setup, configuration, and early product adoption
• Maintain ongoing communication during the first months to ensure retention and satisfaction
• Identify patterns, recommend improvements, and contribute to onboarding documentation
• Collaborate with product and support teams to resolve client needs
• Spot opportunities for upsell or expansion (advantage, not mandatory)

‍

Who we're looking for

• Experience in Customer Success, onboarding, or client-facing SaaS roles
• Excellent English communication skills (spoken and written)
• Strong communication, empathy, and relationship-building skills
• Ability to manage multiple client onboarding cycles at once
• Comfortable leading frequent video calls with clients
• Process-oriented mindset with creativity to improve workflows and client experience
• Autonomy, ownership, and the ability to work in a dynamic environment
• Flexibility for shift-based work

‍

What we offer

• Compensation & Equity: Top-of-market salary in Vilnius plus meaningful equity, so that you own a part of what you build. Salary range for this role is €1,300-1,800 EUR gross / month depending on expertise and experience.
• Health & Wellness: Health insurance, gym membership with personal trainer option, team lunch at the office.
