Square Sense développe des solutions destinées aux grands investisseurs immobiliers (foncières, institutionnels, fonds d’investissement) pour les aider à faire face aux nombreux enjeux auxquels ils sont confrontés et leur permettre d’adapter leurs stratégies de gestion d’actifs plus rapidement et plus efficacement.

Pour ce faire, ces solutions interprètent des données collectées dans les immeubles à partir de plusieurs sources : énergie, IoT, services aux usagers, community management, etc. Elles permettent de comprendre les attentes des usagers, mesurer leur satisfaction et anticiper les situations à risque, et ainsi permettre aux gestionnaires d’actifs de prendre les bonnes décisions au bon moment. Ces solutions ont pour finalité d’améliorer la performance financière des actifs et leur impact sociétal et environnemental.

La plateforme développée par Square Sense met en oeuvre les technologies incontournables en matière de traitement de données massives. Son équipe de data scientists utilise les techniques de pointe en apprentissage automatique pour développer ses applications data-driven.

Square Sense a été fondé en 2017 à Paris par une équipe multiculturelle et talentueuse d’ingénieurs et de scientifiques.

Vos missions au quotidien

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 Python & Scala. 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.

Objectives

As a Data / 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 Data / Back-end Engineer are:

In collaboration with fellow team members, design the data pipelines for collection, storage, processing and BI of data generated by IoT devices and third-party services. Propose relevant technologies and solutions.
Design and develop multiple software components 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 multiple software components for data processing (for example, streaming and batch data pipelines with Apache Spark or Apache Kafka Streams), as well as other internal software, tools and APIs to support the data processing.
Automate data processing tasks and their monitoring in production (for example, orchestration of batch processing jobs using Airflow).
Design efficient data models using various storage technologies (cloud file storages, HDFS, relational DBs and non-relational DBs).
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.
