AI Automation Engineer

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:

ESTO is hiring AI Operations Engineer who will be one of the first builders in its AI Operations team, working closely with the Head of AI Ops and teams across ESTO, with the autonomy to build, experiment, and move fast.

What You’ll Do:

• Build AI-powered automation - design and ship agentic workflows, integrations, and scripts on our AI stack and internal systems

• Remove operational bottlenecks - take ideas from concept to production, understand the problem, design the solution, build it, test it, and iterate

• Keep what you ship alive - monitor the automations you and the team own, catch failures before users do, and refine them as inputs, volumes, and processes change

• Experiment on the frontier - try new AI capabilities and tooling, and turn the promising ones into practical solutions

• Set the standard - establish best practices for AI usage and workflow orchestration.

• Spread what works - turn each automation into a reusable template and share what you learn to build a culture of experimentation across ESTO

What We Expect:

• Solid engineering skills: Python (or similar), APIs, integrations, data

• Problem solver who turns challenges into practical technical plans

• AI-native: excited about AI/LLMs, comfortable experimenting with tooling

• Builder mindset: ships small, tests, iterates from real feedback

• Collaborative across Ops, Engineering, and Product

• Curious: digs into the "why," not just the task

• Ownership mentality: self-directed, fast-moving, comfortable with ambiguity in a role built from scratch

Nice to have

• Automating support/finance/ops processes, AI agent frameworks, fintech/regulated experience

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
