Job description

We’re looking for a dynamic, ambitious and talented Frontend Developer to join our team in Brussels!

About Us:

AppTweak is the leading ASO tool for apps and games driven by data science. Our all-in-one platform provides mobile marketers and app publishers with all the data and insights they need to increase their app or game’s visibility, grow organic downloads and find new growth opportunities.

Launched in 2014, AppTweak is the most accurate, transparent and easy to use tool to grow app businesses of all sizes. Today, AppTweak supports more than 1,500 customers worldwide with offices in Brussels, San Francisco, Tokyo, and Bengaluru and a team of 45 people.

AppTweak has been awarded “best ASO tool” by the App Growth Awards community and was recognized as the 9th fastest-growing technology company in Deloitte Belgium’s Fast 50 competition.

About the Role

The frontend team has full ownership over the architecture and design of our application. We manage massive amounts of data while ensuring excellent performance, thus providing the best possible user experience.

You will work in a team of 3 talented Web Engineers and be directly involved in developing the AppTweak application. You will be in direct contact with colleagues working in different teams (Backend, Product, and Design teams) to deliver new features quickly and ensure the best quality of our code.

At the beginning of AppTweak, we wrote our frontend in BackboneJS and decided to move to React three years ago. Since then, we built a Single Page Application based on React/Redux/Redux-sagas, written in TypeScript, with the standard tooling (Webpack, Babel, ES6, ESLint, and Prettier). To allow our frontend to consume our data, we built a set of services that interact with our API layer (REST APIS built on Ruby). Our infrastructure is based on K8s, and we have created a robust CI system to develop and deploy our code quickly. We deploy directly from Slack!

Your Responsibilities

  • Create, maintain and expand AppTweak's Web application functionalities
  • Collaborate with Product and Design teams to ensure that every feature satisfies our customers’ needs and provides them with the best possible UI/UX
  • Find elegant solutions to usability problems
  • Stay up-to-date on new Web technologies that will make AppTweak better, faster, and stronger
  • Participate in code review, pairing, and other forms of knowledge sharing


Your profile

  • 3+ years of industry experience building fast and reliable web-based applications
  • Knowledgeable about modern web technologies and excited to learn new ones
  • Product minded: committed to making the best user experience
  • Sensitivity to design in general and user experience
  • Excellent communication and collaboration skills

Bonus points

  • GitHub profile or link to open source work
  • Full-stack experience
  • Love food ! (optional)

What’s in it for you?

  • Opportunity to be a part of a Belgian high-growth company where co-creation is not just a buzzword
  • Learn and grow at an open and fast-paced environment
  • Work-life balance
  • Employee and health care benefits

So if you are motivated, ready to learn, and have a curious and innovative mindset, we’d love to meet you!
