Step into the heart of growth and innovation and help build our ambition to become the leading bank for young people. Every day we work within the 'Growth Accelerator 0-30' on innovative digital customer experiences in the Rabo App.

We translate customer behaviour and performance data into sharp insights and informed choices and convert these into scalable solutions with a direct impact on customer experience and commercial results.

In our multidisciplinary teams, you will work together with the best people in the field: from proposition managers and journey experts to UX/UI designers, data analysts, developers, architects, business analysts and product owners. Together we achieve impact from start to finish: from formulating the right customer question to experimenting, building, launching and continuous improvement.

We like pace and action. As a separate department with clear focus and decision-making space, we do not get stuck in reports, but convert insights directly into choices, actions and results.

Together, we are building the future of the bank with strong propositions, smart products and digital experiences that really make a difference for young people.

We are looking for a backend engineer to build the backbone of our Conversational AI interface, enabling customers to interact with the bank in a new and exciting way. You design and develop scalable backend services and orchestration logic that enable AI agents to interpret user intent, manage context and memory, and securely coordinate actions and collaborate with other agents. 

You & your role

Banking is evolving toward a model where conversational AI becomes the primary interface between customers and the bank. Instead of navigating screens, customers increasingly interact through natural conversations, powered by AI agents that understand intent, maintain context, and guide them toward the right financial decisions.

Within the Growth Accelerator 0–30, we build conversational AI capabilities and financial specific agents (e.g. for budgeting, onboarding, or financial insights) that integrate into the bank’s central AI agent, which orchestrates end-to-end customer interactions.

As a Backend Engineer in the Conversational AI team, you design and build the backend systems that power intelligent, reliable, and secure conversational experiences.

You operate at the intersection of backend engineering, AI capabilities, and conversational design. You ensure that AI-driven interactions are not only smart, but also scalable, safe, and deeply integrated with core banking systems.

You work at the intersection of conversational design, AI capabilities, and backend engineering, where you ensure that conversations are not only intelligent, but also reliable, explainable, and safe. You do not just build APIs; you actively shape how conversations are powered, how context flows through systems, and how agents collaborate to deliver meaningful outcomes.

Together with product owners, business analysts, and designers, you translate customer conversations, intents, and journeys into concrete backend capabilities. You define how conversational context is stored and retrieved, how decisions are made within flows, and how responses are grounded in trusted data sources.

Examples from practice

• Designing and building backend services that power key conversational features to support the product orientation for Gen Z customers.
• Building secure context and memory flows so conversations remain reliable, explainable and useful across customer journeys.
• Integrating Large Language Models and AI agents with internal systems through clear APIs, event-driven patterns and trusted data sources.

Facts & figures

• 36-40 hours per week.
• You work within Growth Accelerator 0-30 on innovative digital customer experiences in the Rabo App.
• Over 48,000 Rabobank colleagues worldwide.

Top 3 responsibilities

• Design and build scalable backend services that power conversational AI features for Gen Z customers in the Rabo App.
• Integrate AI agents, Large Language Models and internal systems through well-defined APIs, event-driven patterns and secure data flows.
• Work with product owners, business analysts, designers, data scientists and engineers to translate customer journeys into reliable backend capabilities.

You do not just build APIs. You actively shape how conversations are powered, how context flows through systems and how agents collaborate to deliver clear and trusted outcomes for customers.

Together we achieve more than alone

We believe in the power of differences. By combining people's differences, we become an even better bank. We are curious about what you will bring to our team at Growth Accelerator 0-30.

The teams of Growth Accelerator 0-30 build innovative digital customer experiences in the Rabo App for young people. Collaboration is our way of working; as one innovative team within Rabobank. You work closely with proposition managers, journey experts, designers, analysts, developers, architects, business analysts and product owners to move from customer insight to experiment, launch and continuous improvement.

Work on yourself & the world around you

For us, your development and that of society go hand in hand. That is why we want to invest in you and work together to create a better world. We summarise this in one sentence: at Rabobank, you work on yourself and the world around you simultaneously. This is reflected in your personal development budget, our hybrid work environment and a good work-life balance. You also contribute to digital banking solutions that help customers make better financial choices, in line with Growing a better world together.
