Description & Requirements


We’re looking for a Full Stack developer to join our HRSD team. We are growing both our frontend and backend team and look forward for more multidisciplinarity in the dev teams, to build the next generation of HR delivery services.

We strive to build a work environment in which you will be:

- Working within a friendly, fast-growing, inclusive, progressive company
- Collaborating with a team of talented designers and developers
- Learning not only how to code but how to build a product
- Encouraged to share your knowledge and learn new skills as a Javascript/Java/Python developer, your role is to give life to this platform backed by our design guidelines and our APIs.

Your responsibilities will include:

- Improving existing applications and building new ones
- Sharing your knowledge and efforts across projects to build a strong and consistent development platform
- Learning and teaching with weekly dedicated learning sessions on every side of your skill set

Mentoring is also a first-class element at UKG: depending on the topic and your proficiency, you will be offered to mentor or be mentored.


- Frontend : Javascript, HTML & CSS
We have grown to become big fans of the Javascript framework Ember.js. If you don’t know it, we’ll teach you. If you do know it, come share your experience with us. Besides Ember, you must at least be curious about the evolution of plain “vanilla” Javascript. The JS tribe and our UI designers collaborate to improve our UI framework every day. You will need some proficiency in HTML and CSS to contribute.
- Backend: Java
We are looking for experienced and talented developers who love working with microservice architecture built on top of a Lot of Java/Quarkus/Dropwizard & more and more Scala/Play. Of course, you will also participate to the Java tribe roadmap, projects and experimentations.
- Experience : This is a Full Stack position, so we are looking for experiences on both frontend and backend side. We also deknow that it is impossible to know everything. For example, we are using Ember.js and Quarkus as a main frameworks, but we’re not expecting you to know it. A strong desire to learn is as welcome as an expertise.
- Tooling & Methodology
We are big fans of pair-programming, we dedicate a lot of time to the onboarding of our newest members. Testing is an integral part of our practices and so is peer reviews.
