For our team, we are looking for a senior full-stack engineer. Someone who can not only build good products but also gets energy from coaching teammates and being able to constructively discuss software architecture and development challenges. We want to not only improve our product, but also give a significant boost to our development as a team. If you feel comfortable dealing with both expectations, keep reading!

We build and maintain the application SECA in which all application teams in NN-Group cover their security and compliance requirements. We do this for around 3000 applications with more than 6000 active users, both in our Dutch and international business units. This makes us a crucial part in making all IT within NN-Group safer, and gets us in touch with the entire company. There is continuous demand for developing new features and we are currently implementing a new and improved version of our application. This means you will be working on:

  • Contributing to the redesign of our application, improving usability and efficiency
  • Supporting the backend migration, ensuring performance and security enhancements
  • Developing new features that meet evolving security and compliance needs
  • Collaborating with teams across NN-Group, making IT safer and more streamlined
  • Improving the underlying infrastructure of the application and managing a database migration
  • Shaping the product vision together with the product owner and team

  • On top of that a 13th month and holiday allowance are paid with your monthly salary
  • 27 vacation days for a 5-day working week and one Diversity Day
  • A modern pension administered by BeFrank
  • Plenty of training and learning opportunities
  • NS Business Card 2nd class, which gives you unlimited travel, also privately. Do you prefer to travel with your own transport? Then you can declare the kilometers travelled
  • Allowances for setting up your home office and for internet use

Who you are

  • At least 5 years of experience with Typescript, Angular, Node.js, Nest.js, Jest, among others
  • At least 5 years of experience in working with MySQL databases

  • Experience in Rust and no SQL databases is a big plus

Who you will work with

We are excited to announce a unique opportunity to join our young and dynamic team of 3 engineers and a Product Owner. Our team offers an application to a wide range of stakeholders across the company, providing ongoing business and technical challenges that require ownership and initiative.

Our team is very flexible in terms of location, with team members able to work from various locations with 2 days per week in our office in The Hague. We value a positive team culture and encourage a healthy work-life balance, with occasional games of table football and lots of laughter.
