Are you a structured developer who loves building robust architectures just as much as writing code? Do you want to lead the professionalization of a talented young team while taking our global platforms to the next level?
Join our Data Science Center in Groningen as our new Senior Full-Stack Developer.
About MeMo² (a Kantar Company):
MeMo², part of Kantar, is a leading international player in advanced cross-media research and analytics. We work with top global brands to optimize their media investments using data-driven insights.
A key part of our success is our THX. platform, currently live in the EU5, Netherlands, and Belgium. We are now preparing this platform for worldwide availability. This massive scaling operation requires a solid technical foundation, and that is where you come in.
About the job
We are looking for a Senior Full-Stack Developer with a strong focus on backend, infrastructure, and automation. You won't just be writing code; you will play a pivotal role in bringing our development team to the next phase.
We have a driven, young team of developers eager to learn. You will be the hands-on senior who not only contributes directly to the codebase but also creates a professional development environment. You define the architectural lines, introduce structure, and optimize our workflows.
Your core mission: Scale our THX. platform infrastructure for global usage and automate our internal workflows.
Job Goals
Professionalizing the environment: Setting up and optimizing automated deployment pipelines (CI/CD) and introducing development best practices.
Scaling Infrastructure: Taking the lead in preparing the THX. platform infrastructure for a worldwide rollout.
Backend & Automation: Designing scalable backend services and automating complex workflows to improve efficiency.
Full-Stack Scope: While the focus is backend/infra, you will work across the stack, including occasional mobile development and frontend tasks.
Mentorship & Strategy: Balancing hands-on development with a strategic role; you will help structure the team’s work and mentor junior/medior colleagues.
Collaboration: Working closely with the team lead and project manager to translate business needs into technical reality.
Ideal Skills & Capabilities
To help us make this professionalization step, we are looking for a specific set of skills:
Senior Experience: Strong background in backend development with modern languages (e.g., Python or TypeScript).
Infrastructure Expert: Proven experience with AWS or Azure is a must. You know how to set up and maintain robust cloud environments.
CI/CD Master: You are passionate about structure and have experience setting up automated deployment pipelines.
Broad Scope: Experience with (or willingness to work on) mobile development and frontend (HTML/CSS/JS).
Architectural Mindset: Understanding of databases, APIs, and scalable architectures for global platforms.
Personality: You are proactive, structured, and enjoy helping a team grow. You see problems as opportunities to automate.
Our Offer:
Impact: The opportunity to lead the technical rollout of a global platform (THX.) and shape the way our team works.
Growth: A key position in a company that values innovation; you get to define the technical standards.
Culture: A small, collaborative development team within a dynamic company culture featuring regular team events, lunch gatherings, and office perks.
Balance: A mix of structured long-term projects (platform scaling) and fast-paced, iterative improvements.
And more: Weekly inspiration sessions, access to industry-leading tools, a competitive salary, and a flexible work environment where your well-being comes first.
We are not able to offer visa sponsorship or help with relocation support for this role. Before applying, please make sure you’ve got the right to work in the Netherlands.
