Paris (75)

Dreem has a unique relation to analytics. As a member of the Dreem analytics team, you’ll have the opportunity to work in close relation with nearly all other teams (Product, Marketing, Engineering, Science, Finance).

Dreem’s path and product are unique and to stay successful we rely heavily on data to guide both strategic and day-to-day decisions. Dreem and its users generate large quantities of very diverse data which needs careful and creative aggregation and analysis to provide these crucial insights. By joining our team you’ll be able to guide decisions, create and implement tools to make data accessible in the right place and the right time, all of it fighting one of the most challenging health issue of present times.

More than in most companies, we deal with a lot of diverse data, coming from multiple sources and which needs to be aggregated, aligned and distributed where it matters. As the first dedicated data-engineer at Dreem, you’ll have a unique opportunity to bring the existing ETL pipelines and our current data architecture to the next level. You’ll also play a key role in training the whole company on using data and even delivering insights yourself. To sum it up, we’re looking for someone that embodies completely our mission of diffusing data throughout the company.

Technical context

On the input side, we ingest physiological data from dreem headbands, detailed usage data from the headband, our companion apps and our websites, technical logs, questionnaires, user feedbacks and communication from customer service, data from logistics and growth for instance. We maintain a core postgreSQL data warehouse for all analytics purposes along with an Elasticsearch cluster for logs (with bridges between the two). On the output side, we serve data and analysis through cloud-hosted dashboards (Kibana and Chart.io for non-specialists), notebook-based in-depth analysis and directly in countless third-party tools. Our ETL tools are mainly in python, but we also use some components in go and we use third-party ETL services. Our pipelines run on the latest stacks argo/kubernetes/docker and the ELK.

The Analytics team was created as we sold our very first headbands. Because Dreem is so new, closely understanding our users’ needs and usage has always been a strategic activity. Since its creation, the team has provided insights, tools and training to ensure everyone in the company can leverage data to improve his work.

In addition to “passive” analytics where one looks at normal activity, we also drive many “active” initiatives where we take a more experimentalist approach. Over the years we’ve setup several specialized systems to include our users in product development through large-scale remote tests or targeted feedback collection.
