Principal Developer (Mobile Service Cloud)
Full-time
At CM.com, we help businesses worldwide elevate their customer interactions. With our AI-powered Customer Engagement Platform, we connect conversations, customer data and payments through AI Agents, allowing companies to create more intuitive, personal customer journeys.
We're looking for a Principal Engineer to join the Mobile Service Cloud development team.
What You Will Do
You'll take ownership of the development and architecture of Mobile Service Cloud, our cloud-native contact centre platform that runs 24/7, supporting thousands of customer service agents and resolving millions of inquiries. Trusted by brands like Auping, Fleurop, Revolution Beauty, AS Watson, and Yoursurprise, it consolidates channels like Email, Phone, Live Chat, WhatsApp, Facebook Messenger, RCS, and Native Voice into a single service inbox.
The future of customer service is automation and AI. We leverage technologies like HALO, our own agentic platform, to build intelligent agents that handle inquiries autonomously and free up human agents for complex work. Working with a team of 7 developers in Arnhem, you'll build new features, introduce workforce management tools, and leverage AI for smarter workflows. You'll also take a helicopter view of how Mobile Service Cloud integrates with the Marketing Cloud, Customer Data Platform, Conversational Router, and HALO, actively shaping architectural decisions.
About the Tech Stack
CM.com runs a broad technology landscape from Java and .NET to Rust across a hybrid infrastructure. Mobile Service Cloud runs on Azure microservices. For this role you'll mainly work in .NET backend using SQL and Entity Framework, and we're leading a frontend renewal from legacy jQuery to Vue 3.
What You'll Bring
A strong software engineering background with proven experience on highly complex, large-scale products.
Technology-agnostic thinking: your seniority and AI fluency let you navigate and add value in any stack.
A backend focus, with openness to frontend work in Vue.js.
Solid familiarity with Microsoft Azure or comparable cloud platforms, plus Docker, Kubernetes, and microservices.
AI fluency and a hands-on attitude toward AI-assisted development.
A team-player mentality with a commitment to quality and a growth-oriented attitude.
Fluency in both Dutch and English.
For this position, we can only consider candidates who already hold a permanent work and residence permit for the Netherlands.
