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.

Job description

Products @ Square Sense

Square Sense is developing products to understand people’s behavior and building performance using data collected from sensors and systems within a building. Our models infer knowledge using data from heating, ventilation, and air conditioning (HVAC) systems, lighting, smart meters, Wi-Fi, people counting & occupancy sensors, access control systems, elevators, air quality sensors. These models are based on statistics, probabilistic models, machine learning, and deep learning. The understanding of how a building is used and how it performs under various conditions is used to devise and implement strategies to reduce operating costs, improve the user experience, and increase revenue. Our goal is to develop decision-making support systems and autonomous optimization routines, both at the building level and at the portfolio level (i.e., for clients that own several buildings).

Data analyst responsibilities

Data analysts at Square Sense are responsible for developing products to support decision-making from available data. For such purpose, they develop client-facing dashboards and work with data of various kinds and from multiple buildings. The tasks of a data analyst include quantifying relationships between different variables under various circumstances (e.g., actual or projected), and identifying trends and patterns. They work with the data produced by our data processing pipeline, which is mainly developed and maintained by our engineering and research departments, with whom analysts interact for its design. The data pipeline is responsible for collecting sensor data, transform it using various algorithms and models, and store the results into an analytical database. Data analysts use business intelligence software such as Power BI as well as Python-based tools (Dash, Plotly, Matplotlib) to prepare reports.

Product-driven data analysis

  • Develop production-ready dashboards based on live datasets.
  • Perform data analysis with a rigorous, methodical, and logical approach.
  • Continuously improve the product: identify, assess, and fix issues.

Product design

  • Understand business needs and define the scope of the proposed solution with product management.
  • Proactively propose potential improvements and new use cases to refine product design based on obtained findings.
  • Define precise data querying and processing needs to help improve data models and platform tools in collaboration with the engineering department.

Example products

  • Decision-making support KPIs that track the satisfaction of building occupiers in terms of building operations reactiveness, technical performance, comfort, service offering, and occupancy.
  • Automated and dynamic optimization of the thermal comfort and the energy consumption of a building given current and predicted building occupancy.


  • Collaborate with the project management, product management, engineering, and research departments.
  • Communicate about findings, learnings, and best practices clearly and efficiently.
  • Help to recruit and train interns and junior analysts.
