Description du poste

Who we are

ALOALTO develops and implements end-to-end IoT and Big Data solutions using best of breed technologies for large and medium sized companies.

We’re a fun team of multi-skilled and sharp software engineers, UX/UI designers and data scientists.

Exemples of what we do:

IoT monitoring solutions:

ALOALTO has developed a mobile app allowing an easy and fast way to deploy, activate and link LPWAN multi-sensors with valuable assets (e.g.; fuel tanks, freight wagons, flight cases). In addition to that, we are developing web based applications allowing our clients to monitor these assets (e.g.: track and trace, measure lisquid levels, perform facility management) and trigger alerts when a threshold (e.g.: temperature, humidity, shock, liquid level) is overcome or when an a geofence is breached.

The main technologies we use (amongst others to come):

§ Computer languages: Scala and Java – play framework, Python, Java Script, HTML5,…

§ Databases and data repositories : SQL and noSQL

§ Map technologies : Leaflet, OpenStreetMap, MapBox, Google Maps API

§ Cloud environments: AWS, Azure

§ Big Data technologies: Cloudera, HortonWorks, AWS EMR, Spark, Hive, Impala, Kudu, Kafka, Kibana, ElasticSearch, Flume, Sqoop, Hbase, Pig, Yarn, …

§ Data analysts interfaces: Jupyter, Zeppelin, Tableau

§ Hardware: RaspberryPi, Arduino, LPWAN sensors (LoRa, Sigfox), ...

§ Security: Kerberos, Oauth 2.0, AWS IAM, Azure Active Directory, MFA, Blockchain,

§ Source code hosting: GitHub, Bitbucket

§ Methodology: Agile, Scrum

Telematics big data:

In the context of a big data infrastructure that we have set up on AWS, we have developed an application that ingests massive amounts of telematics data from dozens of thousands of vehicles in order to determine vehicle operations patterns in their environment: route utilization, usage of road infrastructure and facilities. Results are displayed on an interactive heat map allowing our client to gain insights on these operational patterns, and provide recommendations for improvements/optimization.
