Take the lead on 3E's high-performance data engine using Java

Tech stack

  • Java

What you will be doing

Operating and designing a pipeline that can process a high amount of versatile time-series data and protocols in near real-time is a contemporary challenge in terms of performance, scalability, maintainability and flexibility. So far, 3E developers pride themselves in having architected and developed a competitive data processing pipeline that is lean, efficient, scalable and that can be operated by a small team.

The entire platform takes advantage of several programming languages and runtime environments such as Python, Bash, MySQL, Java, Clojure and Common Lisp. We like to refer to it as “energy-efficient software with very low carbon emission footprint”.

We are looking for a talented Java developer who will report to the head of development and will also be working closely together with Sales and Operations.

Responsibilities include:

  • Taking ownership on the entire lifecycle of the high-performance concurrent data collection and normalisation pipeline written in Java, from the architecture and development of new features to its deployment and operation in production environment.
  • Improving the traceability of the data that is processed and capture the configuration of the pipeline into a relational database.
  • Scripting your way on the Linux shell to analyse data or design small command line tools
  • Being available to support our client support team to help them troubleshoot the data load or configuration issues in situations that require a deeper technical knowledge of the platform.
  • As you will grow in the job and obtain experience in the full operational stack, contribute to the REST API architecture of the front-end stack that is developed in Clojure.

Our ideal candidate

To take this important place in the team we are looking for someone with strong development skills who can take the lead on our high-performance data engine. An enthusiastic team player with good written and oral communication skills is exactly what we are looking for!

Troubleshooting and problem-solving is part of the game and stepping out of your comfort zone to learn new things is very welcomed. We would appreciate someone who can think technically with us from the start, setting out a roadmap and different scenarios from architecture to deployment. Proactivity is encouraged throughout the company.

What we are looking for in our new Java Developer:

  • You have a Bachelor's or Master's degree in Computer Science, Electronics or similar with at least 8 years' work experience in an operational environment
  • Performance and concurrent programming on the Java/JVM ecosystem have no secrets for you.
  • Knowledge about functional programming in Clojure or eagerness to learn it.
  • You have experience in designing lean software architectures that scale.
  • You can design efficient algorithms and implement your own code libraries.
  • You have experience in maintaining projects and developing code that pass the test of time.
  • You can think outside of the box and like to understand the platform and domain as a whole.
  • You have experience with Linux command line and Bash
  • Managing end-to-end deployment pipelines from the code repository to Linux servers is no problem.
  • You have used SQL for relational domain modelling
  • You know about REST API design and have UI survival skills
  • You fluently speak English

What we offer in return

3E offers a unique opportunity to further develop yourself in a company/team with an ambitious growth plan, delivering innovative services.

We work in a distributed team. This position is remote-friendly, with the possibility to travel to the Brussels office from time to time.
