Front-End Developer at Roseman Labs



The Role

The core of our Virtual Data Lake uses techniques from modern cryptography to enable unique privacy features. However, the core would be worthless without an intuitive client-facing application – and that’s where you come in! You will play a pivotal role in designing and developing new features in our customer-facing applications in close cooperation with the back-end and DevOps engineers.

This is an all-round position, meaning that the challenges you solve will engage both your development as well as your UI-design skills.

Your Development (major) responsibilities include:

  • Designing and developing web apps, improving user experience on the platforms, and developing new features to enhance the user experience;
  • Keeping a balance between aesthetic design and functionality;
  • Optimizing the web apps for speed and scalability;
  • Agile cooperation with the cryptography and customer deployment teams;
  • Design, develop and implement application solutions that make our products more intuitive and more effective for our users, while not compromising on the strong security and privacy guarantees;
  • Working in sprints with an agile methodology in close alignment with the scrum team and the product owners;
  • Proactively identify opportunities and solutions for improvement of the application code.

Your UI Design (minor) responsibilities include:

  • Design friendly and intuitive UI and APIs (customers typically work in healthcare, law enforcement, energy, and cyber security).


We are looking for a colleague who can identify with the following description:

  • University degree (MSc) in a field that is relevant for the description below, with a curious, creative, and analytical mindset;
  • The ability to translate requirements and mockups into fully functioning web-applications, in close cooperation with the back-end developers;
  • Strong proficiency in web development with experience in HTML, CSS, and JavaScript languages. Experience in front-end frameworks such as Vue or React;
  • Affinity with troubleshooting cross-browser and cross-platform compatibility issues and experience with using the web-browser development tools;
  • Prior experience in designing UI/UX;
  • Experience in designing and building RESTful APIs, especially in Python, is a plus;
  • Hands-on experience with deploying on Linux environments is a plus (being comfortable on the command line);
  • You have an international orientation and experience. You speak English at a professional level;
  • You are hands-on, proactive, organized, and structured. You have a strong eye for quality;
  • You are creative and not afraid to step outside of your comfort zone. You can quickly respond to changes in the environment and deliver short-cyclical value in an Agile way;
  • You enjoy working in a small team of a fast-growing start-up with many opportunities but also many uncertainties.

We offer attractive employment conditions that suit a start-up in this phase; participation is an option. We value a high-performance culture built around our core values: customer, quality, and team. Where, how, and when you work is up to you.

Please include links that highlight your relevant experience, such as GitHub, Stack Overflow, or portfolio websites.
