AI-Native Customer Success Engineer

OperAI-Driven Full-Stack Customer Success EngineerEmployeeEngineeringAbout OperOper, 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-Native Customer Success Engineer to join our mission and help shape the future of automated mortgages in Europe and beyond.Your MissionIn this role, you will own the technical side of getting our product live and running smoothly for specific customers. The work spans a wide range, from focused changes like a custom acceptance rule or a contract template adjustment, to more complex custom integrations and micro-services. You'll work within the frameworks the product team provides, extending them with new business logic and journeys rather than conceptualising major new features, all with the goal of getting more clients live on Oper and keeping them successful. This is a role for someone who is AI-native, who uses modern AI tooling as a core part of how they think, write, and ship.TasksWhat you’ll doOwn the technical implementation of customer installations: configuring acceptance and business rules, adapting contract templates, building custom integrations and micro-services, and extending existing product frameworks with new logic.Work closely with the rest of the CS team across multiple clients and projects at once, switching context comfortably between different people, codebases, and problem areas.Be customer-facing: joining meetings and workshops with clients and system integrators, translating their needs into technical solutions.Liaise with the product team to suggest improvements that let us onboard clients faster.Work AI-nativeWe expect you to use modern AI tooling as a real lever, not a curiosity.Write code AI-first: agents produce the bulk of your code under your direction, while you own the architecture, integrations, review, and quality. We measure your output in shipped customer value, not hand-typed lines.Build agentic workflows that do real work: scaffolding integrations and micro-services from a spec, generating and running tests, drafting configuration and contract logic, and reviewing diffs.Use modern AI coding tooling as the default way you build, configure, and debug, not as an occasional helper.Identify where AI compounds your work and where it does not, and design your workflow accordinglyAim for a delivery cadence a non-AI-native engineer simply cannot match, and help us raise the bar on what an AI-native delivery function looks like at OperRequirementsWhat you’ll bring3 to 5 years of experience in software development.Full stack → Python (Django or FastAPI) on the back-end and Angular on the front-endSolid experience with REST APIs and integration work, comfortable shipping across the full stack from Angular front-ends to Python services.Comfortable working with flexible and loosely...
