Quick summary: We're looking for a Customer Support Specialist, who would be the friendly face of Sintra, ensuring our customers receive the best possible experience.

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
  • Handle customer inquiries across support channels
  • Resolve issues quickly and accurately
  • Contribute to a seamless overall customer journey
  • Build and maintain support automations
  • Collaborate closely with the development team on technical or complex cases
  • Document feedback and escalate issues as needed

Who we're looking for
  • At least 1 year of experience in customer service, ideally in B2B SaaS or consumer products.
  • Ability to work evening shifts (17:00 PM to 1:00 AM) on a shift-based schedule.
  • Proficiency in English at a professional (or ideally bilingual or native) level.
  • Experience in building automations and workflows would be an advantage.
  • High energy, proactive mindset, and a readiness to assist.

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 €2,500-3,000 EUR gross / month depending on expertise and experience.
  • Health & Wellness: Health insurance, gym membership with personal trainer option, team lunch at the office.
