Do you want to make a direct social impact with your work? Join Populytics!

About Populytics

At Populytics, we empower policymakers to make decisions that better reflect the preferences, values, and concerns of citizens — strengthening democracy in the process. We specialize in large-scale online citizen consultations based on scientific methods, enabling thousands of people to share their views on complex policy questions in a reliable way. Our clients include governments such as municipalities, provinces, ministries, and the Dutch House of Representatives.

How we work

You’ll be part of a dynamic spin-off from Delft University of Technology (TU Delft). Our organization includes 16 researchers who design policy questions and present them to citizens through our online platform. They also analyze and report the resulting data so that policymakers — from aldermen to ministers — can use it to make informed decisions. Your researcher colleagues are also your users: they configure the citizen consultations directly within our platform, Wevaluate.

We carry out our citizen consultations through our proprietary platform, Wevaluate. A small software team ensures that Wevaluate runs smoothly and is continuously improved. You’ll work closely with a mid-level fullstack engineer based in Austria, a product owner, and occasionally a UI/UX designer.

Your role & responsibilities

As a Senior Fullstack Engineer at Populytics, you’ll be responsible for maintaining and managing our Wevaluate application and its system architecture. You think beyond the code: you ensure that Wevaluate remains stable, scalable, and future-proof. You identify technical challenges early, assess their impact, and tackle them with structural, long-term solutions. You understand application architecture, think ahead about scalability and performance, and know how to set priorities effectively.

About you

You bring at least 8 years of experience as a fullstack engineer and recognize yourself in the following:

• Experience with PHP (preferably Laravel);
• Experience with JavaScript frameworks such as Vue (preferred), React, or Angular;
• Experience with cloud architecture, preferably AWS (especially CloudFront, Lambda Functions, DynamoDB);
• Experience with Git and CI/CD pipelines;
• Experience with quality control processes such as unit testing and code reviews;
• Knowledge of Linux and server management;
• Nice to have: affinity with UI/UX principles and an interest in improving user experience
• Strong architectural insight — you understand how systems fit together and proactively think about scalability, performance, and long-term risks;
• You value clean, testable, and maintainable code;
• You enjoy working in a small, independent team;
• You are proactive and bring your own improvement ideas;
• You work efficiently and solution-oriented — you can quickly track down and fix bugs when they occur;
• You have strong English communication skills; Dutch is a plus;
• You live in the Netherlands and can be at our office at least one day a week.
