Lead Data Engineer

KMTX is a genuine tech business founded in 2017 by two serial entrepreneurs: Franck Tetzlaff - one of the founders of Doctolib, a French unicorn - and Arthur Querou - founder of MotionLead, which was acquired by Adikteev. We raised €3m and undertook 2 years of R&D to build our technology, before launching commercially in 2019. Over 150 brands currently use KMTX to run their digital campaigns including Toyota, ASUS, Samsung, Danone, Coca-Cola, Adidas, Lufthansa, and IBM.

KMTX empowers advertisers and agencies to make programmatic media decisions with a scientific approach. We're focusing on solving the most difficult problems in marketing and advertising to build a better, open, and fair ecosystem. We believe that science and technology are the most important drivers of change in today's world. And that change is needed, especially when it comes to online advertising.

At KMTX we believe that small increments don't drive change. Anything we do must be 10x better than what existed before.

This also applies to hiring. We hire people that are 10 times better than us. People who want to build and achieve 10x challenges. People who are forward-thinking, who challenge the status quo, get out of their comfort zone, are not afraid to fail, have a high-level of self-awareness and expectation while parking their ego at the door.

We also believe that to perform at their best, our people should be happy. Working hard does not mean setting aside your own comfort or personal life. We take care of our employees with a suite of benefits and perks which help create a beneficial environment: for work and life.
