(Medior) Back-end engineer Conversational AI – Growth Accelerator

Step into the heart of growth and innovation and help build the ambition to become the leading bank for young people. Every day, the team within Growth Accelerator 0-30 works 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 multidisciplinary teams, you will work together with proposition managers, journey experts, UX/UI designers, data analysts, developers, architects, business analysts and product owners. Together, the team achieves 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.

Rabobank is looking for a backend engineer to build the backbone of its 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, 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, for example 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 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.

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 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

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.

You & your talent

• (Senior-)level experience in backend software engineering, with at least 3 years of experience in a similar role.
• Backend development using Python and Java.
• Designing and implementing REST APIs and integration patterns.
• Familiarity with orchestration patterns, for example A2A and workflows.
• Experience with AI-agent architectures, including tool invocation, context persistence, conversation state and guardrails.
• Event-driven architectures, messaging platforms and distributed system patterns.
• Security, privacy and compliance considerations when exposing data to AI agents.
• Observability, including logging, metrics and tracing, and reliability engineering in AI-augmented systems.
• Hands-on experience integrating AI/LLM-based components into backend systems, including prompt orchestration, tool or function calling and context management.
• Experience with distributed systems and API design, and familiarity with event-driven or message-based architectures.
• Ideally, you have previously worked at Rabobank and are familiar with our backend and integration landscape.
• A strong sense of ownership: you’re proactive, quality-driven and comfortable making architectural trade-offs in complex environments.
• A customer- and outcome-focused mindset; you understand that backend design directly impacts customer trust, explainability and experience.
