Job Role

We are on a mission to make science open so everyone can live healthy lives on a healthy planet.

What we have to offer

Frontiers is a young, fast paced technology driven company with a large IT department to support its goals.

In Frontiers we are using microservices architecture to build our platform, and a distributed architecture leads to distributed data. In order to enable our business to make fast decisions, and facilitate the rapid growth of the platform, we started our journey of data consolidation and federation. You’ll join the team of developers responsible for designing and building the next-generation data integration layer that will serve our internal and external consumers.

About You

The ideal candidate will be working together with Product owners, Stakeholders and QA engineers for developing and maintaining our data integration layer. In addition to building and maintaining current solutions, you will be responsible for overseeing the next technological enhancements of the company. You will also be in charge of research, design, prototype and develop new solutions using innovative technologies and approaches.


  • Minimum 4 years of experience;

  • Experience with TypeScript and Node.js;

With more than 50 nationalities represented in our global team, you will work regularly with teammates in other countries, and with our community of researchers, editors, and authors from around the globe.

Our mission to create solutions for healthy lives also extends to the working environment we provide for our employees.

This includes:

100% remote working

Employees now have the flexibility to choose where they want to work, with remote working available on a part- or full-time basis (not applicable to some Workplace/IT jobs due to nature of role requiring presence onsite, in the office).

Learning and development

All employees have access to LinkedIn Learning (and Pluralsight for our technology team), an annual personal learning budget, and dedicated L&D time.


We offer free online yoga classes, an employee assistance plan, access to the Headspace app, and four wellbeing days on top of your annual leave allowance.

Employees can dedicate three days each year to volunteer for a personal cause or through our volunteering partner platform, Alaya.
