Job description

Software Engineering at Square Sense

In Square Sense’s Software Engineering Team we are building a multitude of products in the domains of data collection, analysis, visualization and IoT manipulation. Our systems collect data from IoT devices and third-party data sources, process ingested data in streaming and batch modes, organize processed data, provide the APIs to access it (analytics platform), or use third-party APIs to manipulate the physical world (automated decision making solution).

Our main programming languages are Scala and Python. Our solution is built with modern technologies such as (list is not exhaustive): Docker and Kubernetes, Kafka stack (Kafka, Kafka Connect, KSQL), Spark, Airflow. Our production platforms run in the public clouds (Azure, GCP, AWS) and employ related services such as GKE, Dataproc (GCP) and AKS, HDInsight (Azure) to name a few, and we deploy the software in a Continuous Delivery process. We focus on a high quality of our software and all team members take seriously such practices as automated testing and PR reviews.

All team members participate in the design and architecture, development, quality, production delivery, and monitoring.


As a Back-end Engineer you will be a member of the Software Engineering Team. This position implies close collaboration with all members of the Software Engineering Team, as well as members of our Data Science Team, who design and implement various data processing algorithms.

Primary objectives of a Back-end Engineer are:

  • In collaboration with fellow team members, design the architecture for various software and APIs in the domains of business processes modelling, modelling and automated management of the buildings and IoT sesnor networks, as well as data processing. Propose relevant technologies and solutions.
  • Design and develop software for data collection (connectors for various IoT devices and third-party services, web hooks) and ingestion of collected data (using Kafka, for example).
  • Design and develop software and back-end APIs for buildings, IoT management, and process modelling and automation.
  • Develop internal APIs, tooling and libraries.
  • Collaborate with Data Engieenrs and Back-end Engineers in architecture design and implementation, with Data Scientists to support the research activities, and with DevOps Engineers to deliver to production all software you develop.
