The posting

About ESTO

Founded in 2017, we are a fast-growing fintech company on a mission to make shopping and financial decisions effortless. By combining smart technology with customer-first thinking, we enable people to pay flexibly and businesses to grow faster.

As a team, we value ambition, ownership, and constant improvement. We move fast, think big, and build solutions that make a real impact on everyday lives.

About the role:

There's no open seat right now. This is an open door. If you build with AI, we want to get to know you and find a fit in ESTO for exceptional people.

Our AI Operations team rebuilds how ESTO works, one process at a time. An AI Builder sits where three skills meet: engineering, systems design and product thinking. You find the work that eats a team's week, build the system that takes it over, and own it in production.

What You’ll Do:

  • Sit with teams across customer support, legal, marketing, finance etc. Find out what they need, not just what they ask for.
  • Build agents, pipelines and internal tools that change how ESTO operates.
  • Plug them into the tools we already run.
  • Own your solutions end to end: deploy, monitor, iterate, fix when they break.
  • Measure everything: quality, cost per task, hours saved, adoption. If nobody uses it, it doesn't count.
  • Teach as you go, so colleagues start building too.

What We Expect:

  • You've built prototypes or systems using LLMs. Show us.
  • Solid understanding on software engineering principles and agile ways of working.
  • You know how to design for failure: validation, human checkpoints, fallbacks.
  • You also know when not to use AI.
  • Claude, Cursor or similar are daily tools, and you know where they break.

Nice to have experience with:

  • Fintech, lending or another regulated industry.

Why You'll Love Working Here

  • 28 days annual leave + public holidays + your birthday off, always
  • Hybrid work with flexible hours
  • Paid sick leave + 3 wellbeing days
  • Modern, pet-friendly office in the heart of Tallinn
  • Fully stocked kitchen: snacks, fruit & drinks
  • Monthly Stebby allowance for sports & wellness
  • Collaborative, multicultural team
  • Regular events & offsites
  • Room to bring ideas and make real impact

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
