Luxoft

<div><div><h5 class="jobSectionHeader"><b>Project description
</b></h5><p>Luxoft is one of the major software services companies world-wide. In particular, we develop high quality software in automotive industry for most famous car makers.
<br>
<br>
The software inside a vehicle was traditionally expected to be a very controlled and self-contained environment. Equipping cars with perception and machine intelligence changes a lot in the overall picture of the vehicle manufacturer. Luxoft's goal is to empower our customers, with deep domain knowledge and smart solutions, to develop cars of the future.
<br>
<br>
The project is dedicated to the development of the tools for virtual testing of ADAS systems using data-driven development approach. Tools will allow testing and validation of higher automation level cars. The target SAE automation level is 3, which means that the car will be fully responsible for driving under specific conditions (highways, specific areas, traffic jams, etc). To bring fully autonomous car to the roads and to bring the future to reality, their safety has to be proven, for this purpose the testing on private grounds or on public roads is not enough as it requires hundreds of millions of kilometers to ride, so the alternative way of testing - virtual testing and data based testing - is becoming more and more actual.
<br>
<br>
For the development of the next generation tooling for ADAS (Advanced Driver Assistance Systems) and HAD (Highly Automated Driving) functions for a major German car maker, we are looking for a talented software engineer.
<br>
<br>
Join our enthusiastic and experienced team and develop software for the vehicles of future that will be used on a daily basis by millions of drivers once the next generation of cars hits the roads starting from 2025.

</p></div><div><p>Stay abreast of industry trends and technologies, ensuring that our solutions remain innovative and aligned with best practices.
