Berlin, Berlin, Deutschland Unique Vollzeit 80.000 € - 120.000 € pro Jahr

Job Description
Defining how AI and finance work together — securely, intelligently, and at scale.
At
Unique
, we're building
agentic AI infrastructure
that financial institutions can trust. Our systems combine deep technical engineering with enterprise-grade reliability — bringing automation, insight, and adaptability to some of the most demanding environments in global finance.

We've recently raised our
Series A
and are scaling fast. Few teams are tackling the complexity of making AI truly enterprise-ready for finance — we're one of them, and we're growing quickly.

We're looking for a
Senior Backend Engineer
who thrives on deep technical challenges, ownership, and collaboration.

If you know how to write
heavy processing code without blocking the event loop
, or reason about and extend systems
you don't fully control
, this is the environment where you'll thrive.

  • Own the full lifecycle — architecture, implementation, deployment, and observability.
  • Champion best practices in security, reliability, and performance.
