Developer Yokai

This is a hands-on senior role for an infrastructure and network engineer who owns architecture: you set and evolve the technical direction for the platform's core as it scales toward a few thousand users. 

• Own the network architecture. Set and evolve the platform's network topology and set-ups (IP ranges, DNS, VNets) in Azure, and later AWS, making the design decisions that are hard to reverse once it serves a few thousand users. 

• Build governed self-service. Turn a team's request into a running environment through infrastructure-as-code, so onboarding happens on paved paths rather than manual support. 

• Set the standards others build on. Create the abstractions, golden paths, and guardrails that let teams move fast safely, and make the platform self-explanatory rather than dependent on your time. 

On a day-to-day basis, your work comprises 

• Design and implement infrastructure components for Azure.

• Train juniors and other teams in the utilization and extension of our platform.

• Work in a scrum setting.

• Remove compliance issues and close vulnerabilities.

• Automate everything.

• 36 - 40h per week 

• over 2,000 colleagues using analytics services within Rabobank 

• 9.5 million customers worldwide  

• Ensure security of our platform.

• Train new or junior team members.

• Detect inefficiencies and remove them on a technology level.

“We serve hundreds of data scientists with our platforms, and this centralized way of catalyzing our colleague’s work with state-of-the-art methods will be crucial in the age of AI.” Mathis Habich, Tech Lead 

 
The 50 people of One!Prod serve the entire Rabobank to provide an enterprise-grade platform for data scientists to carry out their work. Collaboration is our approach; as a member of team Yokai, you will help ensuring the usage of enterprise-grade and enabling analytics services. 

For us, your development and that of society go hand in hand. That’s why we want to invest in you and work together for a better world. We summarise this in one sentence: ‘At Rabobank, you work on yourself and the world around you at the same time. You’ll see this reflected in your personal development budget, our hybrid working environment, and a healthy balance between work and home. You can work on banking services for our private and business customers, as well as societal issues such as food and energy transitions. 

 At Rabobank, we believe we become stronger through people who complement each other. By embracing our differences, we bring out the best in one another. We seek diversity in areas such as knowledge, skills, and experience, but also in gender, background, and culture. Across every department, we strive for variety and the freedom to be yourself – whoever you are. That’s what diversity and inclusion at Rabobank is all about  

Must-have 

• Azure networking at scale. Deep, hands-on experience with VNets, DNS, IP address planning, and network topology, and a feel for the decisions that are hard to reverse once a platform serves many teams. This is the part of the role we most need you to be strong in. 

• Infrastructure-as-code with real state discipline. You think in terms of state, drift, and resource ownership, not just running deployments. We use Pulumi as our primary tool; experience with Terraform or Bicep transfers well. 

• Governance and policy-as-code. Designing and enforcing guardrails at scale: policy, least-privilege identity, and secure-by-default automation, so the platform stays compliant as it grows. 

• Ownership. Ability to lead smaller initiatives front to back with 1-2 engineers. 

• Delivery fundamentals. CI/CD with Azure DevOps and Azure Pipelines, and comfort in at least one language such as Python, TypeScript, or C#. 

Nice to have (a genuine plus, but none is required and no one person is expected to have all) 

• Databricks on Azure and Internal Developer Platforms (IDPs). 

• A working understanding of analytics and data-science workflows, enough to build the platform they run on. 

• Exposure to AI services or AWS (for example Azure OpenAI, Azure Foundry, or AWS Bedrock). Useful context, not a selection criterion. 

Soft skills 

• Abstract thinking, strong communication, motivation to improve processes, proactive, team player. 

• Energy to engage with users of vastly different backgrounds almost daily. 

• Eager to keep learning, because this field is anything but static. 

• Good command of English. Dutch is purely optional.
