up to 6000 $
Full-time
Remote
Experience: 5 years

Country — Estonia

Salary — 4-6 K USD

Working hours — European standard working hours, GTM+3

 

Most sales tools help you send emails. We’re building something different. We’re creating autonomous AI agents that can:

  • Find the right prospects
  • Generate highly personalized outreach
  • Run conversations
  • And book meetings
  • All without human involvement.

 

Why this is interesting:

A lot of AI products stop at “generate text.” We’re focused on outcomes.

 

 

That means solving problems like:

  • How do you generate messages that actually get replies?
  • How do you evaluate and improve agent performance over time?
  • How do you orchestrate millions of AI-driven interactions reliably?
  • How do you combine structured data + LLMs in a way that scales?

If you enjoy working at the intersection of systems + AI + real-world feedback loops, this will feel like a playground.

 

 

What you’ll be working on

  • You won’t be maintaining legacy systems.

 

You’ll be:

  • Designing and building core backend systems that power our AI agents
  • Creating APIs and services that handle high-scale, real-time workflows
  • Working with queues (Kafka / SQS / RabbitMQ) to orchestrate async systems
  • Thinking deeply about performance, cost, and reliability in AI pipelines
  • Shipping features end-to-end with a small, senior team

 

The team

  • We’re a small group of experienced builders. We move quickly, care about quality, and avoid unnecessary process.
  • No layers of management.
  • No long planning cycles.
  • Lots of ownership and autonomy.

 

What we’re looking for

  • 5+ years of backend engineering experience
  • Strong system design fundamentals
  • Experience with distributed systems and async processing
  • Familiarity with relational and/or document databases
  • Clear communicator, high ownership

 

Why join

  • You’ll work on a product where the output is measurable (meetings booked, revenue generated)
  • You’ll have real ownership from day one
  • You’ll be early in building a new category (AI sales agents)
  • You’ll grow as fast as we do
