Senior Frontend engineer: visualizing streaming data

Klarrio is looking for a senior frontend developer that can build the visual interface between our customers and their streaming data platform.

Your tech challenges & responsibilities

At Klarrio we are specialized in building streaming data pipelines and IoT platforms. Because these platforms are typically highly dynamic, data updates are streamed from the backend towards the frontend so that users always have access to the latest data. In this lies the challenge to show both big data blobs as well as the individual datapoints in an efficient way.

As a senior frontend developer it is your responsibility to develop user interfaces that are reactive and that scale, implemented with best practices and code quality in mind.

The projects you’ll be working on

Given that we have multiple clients, you will be working on a wide range of projects in various domains (Smart Cities, Transport & logistics, Telecom, Public Infrastructure) in an international context.

The user interfaces for these projects are (mostly) web applications, but also desktop apps (e.g. using Electron), mobile apps (e.g. using Ionic) and reusable libraries.

The user interfaces we build can typically be divided into 3 categories:

  • Data Visualization: exposing the data within the platform in a streaming manner, with some interactivity
  • Platform & Data Management: user interfaces to manage the configuration of a platform, or the data within it
  • Platform Insights: custom (interactive) visualizations to expose platform internals

The team

You’ll become part of an agile, multidisciplinary R&D team. We have a no nonsense mentality where we just want to get things done, lean and mean. Continuous research and education are crucial for the Klarrio team to stay ahead in the various domains. We have a strong culture of knowledge sharing, both internally as well as externally.

Skills & Requirements

  • For enterprise-grade user interfaces you will be working with frameworks such as Angular, while for less complex visualizations you will be using lightweight JavaScript/Typescript libraries.
  • For communication with a backend both REST and MQTT are commonly used.
  • Apart from these frontend related technologies you’ll also use Docker and DC/OS to deploy your applications.
  • Being Klarrio, we are always on the lookout for better technologies that can improve our stack, using the best tools for the job at hand. So the R in R&D is an important part of your job.
  • Knowledge of Kafka or other great open-source technologies is a plus.

Compensation and benefits

We will introduce you to a new world or accelerate your skills

On top of a competitive compensation package, we’ll add Performance Bonuses, Health Insurance, Retirement planning and a Mobility Package.

A place to learn, experiment and exercise your brain, in order to strengthen your powers and feed your passion. Internal and external training programs to grow your skills.
