In over 20 projects we are working with a variety of technologies: Machine Learning, Computer Vision, Cloud, Big Data, Frontend, Backend, and others.

Requirements:
- Requirements:
- Mandatory Skills:
- 3+ years of experience with Java
- 1+ years of Apache Flink experience
- Nice-to-Have Skills:
- Knowledge of deployment tools
- Hands-on experience in automated testing tools
- Experience with fleet tracking (automotive domain)
- Job responsibilities:
- Work with a platform that uses Apache Flink
- Consult existing developers on the integration of components with Flink
- Collaborate with a globally distributed team of other developers, business analysts, and quality assurance (QA) professionals
- About Project:
- Technologies used: Java 8, Apache Flink

Responsibilities:

The scope:
- Gps coordinates of all devices in the system are produced on Kafka (as well as different device events)
- Currently, we have the algorithm that calculates “trip statistics” for GPS data for a given vehicle (it divides the gps data into different trips according to the time difference between points (more than 5 minutes) and certain events from the device
- Trips statistics include info like a starting point, endpoint, duration, distance, max speed, number of events, etc.
- The problem with the current algorithm that it runs each time when we request it and it is not saved in the DB
- The goal is to create a Flink job that will calculate those statistics on the fly and store them in a DB. Latency requirement ~2 minutes so that the ongoing trip will re-calculated and be up to date with all data at least up until 2 minutes ago.
- The order of GPS coordinates is not guaranteed, there could be “holes” in the GPS series potentially and other edge cases that need to be handled reasonably. And this requires kind of a design for it
- Both GPS data and trips data should be stored in Scylla DB (this is exactly the same interface as CassandraDB)
- We need it as a separate microservice and covered by unit tests
