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

We are looking for a talented Clojure & Java Back-End developer. You have a passion for Clojure but don't mind shelling out to low-level Java when performance is required. You will report to the head of development and to our CTO.

Your tasks will include but are not limited to:

  • Take ownership on the entire lifecycle of the high-performance in-house ETL engine and its integration with a new site information model database (digital twin)
  • On the Clojure side, you will work on a solution that let end users manage the site information model for the configuration of the ETL engine
  • On the Java side, you will work on scaling the high-performance concurrent data load engine and its integration with the new persistent information model in Clojure

Our ideal candidate

Our ideal candidate is 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 Clojure & Java back-end developer:

  • You have a Bachelor or Master's degree in Computer Science, Electronics or similar with at least 8 years' work experience in an operational environment
  • Strong background in declarative programming in Clojure
  • Strong background in thread-safe concurrent programming in Java
  • You have moderate knowledge on scaling distributed systems (queuing, sharding, caching, …)
  • You have a moderate background in SQL
  • You fluently speak English

Bonus points for:

  • Knowledge of other languages
  • Familiarity with Renewables Energy Sector, IoT, OT

What we offer in return

Our offices are hidden in the centre of Brussels with a view on a pond, with ducks and a heron bringing a regular visit. In addition to a stimulating atmosphere in a highly motivated group of people, 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 possibility to travel to Brussels office from time to time.

Furthermore:

  • Attractive salary package in line with your level of experience, including group insurance, hospital insurance, meal vouchers (8 euros), eco vouchers, representation allowance, company mobile phone + subscription, 32 days of vacation and a flex income plan.
