Fullstack Engineer — Own End-to-End Fintech & AI Systems

Anyfin AB; Stockholms kommun; On-site; Full time

Job description

We’re hiring engineers. Not ticket-takers.

At Anyfin, we’re building financial infrastructure and products used by millions of people across Europe with a deliberately small engineering organisation.

That means we care a lot about who we hire.

What the role actually looks like

This is not a place where engineering sits separately from the business.

Small cross-functional teams own their work end-to-end, from identifying problems and shaping solutions to shipping and operating them in production.

Engineers here work closely with product, data and commercial teams to solve real-world problems across:

• Payments
• Credit decisioning
• Customer experience
• Operational tooling
• Internal AI systems
• Scaling infrastructure across markets

There’s very little ticket-pushing and very few handoffs.

We value people who can think independently, make sound tradeoffs and move things forward without unnecessary complexity.

Tech

• TypeScript
• React / React Native
• Node.js
• Python
• Go
• GraphQL
• PostgreSQL
• BigQuery
• Kubernetes
• GCP

We also use AI heavily in day‑day engineering work and product development.

AI and machine learning have been part of Anyfin since the beginning, originally through credit assessment models, and increasingly across operations, tooling and product experiences.

Today we work with multiple frontier models, build internal AI tooling and agent infrastructure, and are investing heavily in AI‑powered financial experiences.

Why engineers join

• Real ownership
• Smart colleagues
• Modern tooling
• Complex systems without legacy bank infrastructure
• Fast decision-making
• High standards without unnecessary bureaucracy

We’re intentionally not building a huge engineering organisation.

We’d rather have fewer strong engineers with high trust, high expectations and meaningful impact.

How we work

The engineering team works together from our Stockholm office during most of the week. We genuinely believe collaboration, fast feedback loops and problem‑solving work better that way.

A few practical notes

• Stockholm and office‑based, because we believe that great products and culture are better built when you meet in person.
• EU work authorization required.
