AI Solutions Engineer

Oper, a European Fintech company, is a leader in cloud-based digital mortgage software. We provide personalized journeys for borrowers and lenders. Oper's technology streamlines the mortgage application process, eliminates paperwork, and increases transparency.

The fastest growing part of our business is Herman, our AI agent for mortgage origination. Herman reads documents, checks them, and works a credit file the way an analyst would, inside the regulated workflow of a real bank. It runs on sovereign EU infrastructure, because our clients cannot send mortgage data anywhere else. Phase by phase, it automates more of the origination process: first employed borrowers, then the self-employed, and onward. This is not a chatbot bolted onto old software. It is agentic software doing real work in a regulated environment.

A passionate and engaging team of around 30 stellar Fintech operators works vigorously to transform European mortgages by enhancing efficiency and alleviating borrower anxiety. Backed by Bessemer Venture Partners and Motive Ventures, we have raised EUR 14 million, placing Oper at the forefront of revolutionizing mortgages in Europe. Oper currently has offices in Zürich, Switzerland, and Antwerp, Belgium.

Now, we're looking for an AI Solutions Engineer to join our AI Squad and help shape the future of automated mortgages in Europe and beyond.

Your Mission

You'll join the AI Squad, the team building Herman. This is a hands-on, hybrid role spanning AI engineering, product management, and solutions architecture. You'll scope and build working AI prototypes, take them in front of real banks to pressure-test against live mortgage workflows, and work alongside the team to turn these into working Herman features. You own delivery end-to-end: from a rough use case to a shipped capability, communicating progress clearly the whole way. This is an applied role, not a research one. We want a builder who can both code and collaborate, who is comfortable in front of a client in the morning and deep in a codebase in the afternoon.

What you'll do

• Scope and build working AI prototypes
  - LLMs, RAG, agentic automation, and integrations
  - that solve concrete origination problems.
• Engage directly with clients: run workshops, gather requirements, demo, and iteratively refine solutions against the real workflows of regulated banks.
• Define and manage AI use cases, structuring them functionally so they can scale beyond a single client.
• Work closely within your team to turn validated prototypes into production features.
• Own delivery timelines and communicate progress clearly to both clients and internal stakeholders.
