Senior Back-Office Full Stack Developer

by:  Relax Gaming Ltd

The job offer is available for the following event:

Relax Gaming is a game studio and content aggregation platform for the casino (iGaming) industry. We were founded in 2010 with the goal of simplifying B2B content creation and distribution for the rapidly evolving online landscape of the biggest casino names in regulated markets. With transparency and collaboration central to our ethos, we’ve rapidly increased our team since the beginning of 2018 and we’re continuing to grow fast!

You will be joining the team of one of our most successful and celebrated products – Bingo. Our Bingo product operates in multiple markets with multiple brands like Unibet,, Maria Bingo VladCazino, and Bingohuone, and is used by thousands of players each day.

Job Summary

We are looking for a solid Senior Full Stack Developer to join our Bingo development team to work on our Back-Office. Our Back-Office is the gateway into the heart of our Bingo System and is used heavily by us and our customers. Bingo is actually quite a complex game and the amount of tweaking, configuring and fine-tuning that needs to happen is high. Combining this with the challenging environment of regulated online gambling and the Back-Office is at the centre of a lot of what we do.

You will be leading the development efforts on our Back-Office. The current Back-Office is a legacy system in Ruby on Rails, and, together with the Bingo Team, you will have the opportunity to rewrite and rework this system in a way that makes the most sense for the product and for the end-users.

You will be key in the development and progression of the Back-Office, leading the development from the current legacy system into whatever shape the Back-Office will end up in. You will have a junior developer to assist you in this, and you will be responsible for their daily work as well as mentoring and teaching them.

As part of the Bingo Team, you will be reporting to the Bingo Team Lead and will be working alongside fellow frontend and backend developers and QA using Agile processes. Given the importance of the Back-Office, you will also be directly in touch with the business when required. 

While this is a full-stack development role, the emphasis is on the frontend with JavaScript and CSS. Solid Java is required primarily for the creation and modification of APIs as required.


  • Own and lead the development of the Bingo Back-Office
  • Mentor and guide junior developers
  • Ensure quality and stability in the Back-Office throughout the SDLC
  • Ensure deadlines are met without compromising on quality or stability  
  • Work with other developers within the Bingo Team
  • Work with other developers and technical staff elsewhere in the company, such as DevOps

Job Requirements:

  • Four years of experience in IT
  • Excellent JavaScript, markup and CSS knowledge
  • Solid Java knowledge
  • Experience in Javascript frameworks, eg. React, VueJS and ES6
  • Experience in building and working with APIs
  • Good knowledge of Agile development practices
  • You are open-minded, keen to learn and gladly share your knowledge with fellow developers
  • You are a positive, self-motivated team player that gladly speaks your mind
  • You thrive in a fast-paced environment and embrace having many projects running at the same time
  • Excellent verbal and written communication skills in English
  • You are excited about playing a big part in shaping the future of the slickest gaming products of the industry

Bonus points for…

  • Excellent Java knowledge
  • Previous experience building Back-Offices
  • Knowledge in Ruby
  • Previous experience in Bingo products
  • Previous experience in iGaming
  • Passionate about games and an interest in gambling
