Flightradar24 is one of the most successful growth-stage tech companies in Stockholm. Each month more than 80 million aviation enthusiasts visit Flightradar24, and our Commercial Services team works with some of the biggest names in aviation. We are looking for a Tech Lead to take ownership of the engineering efforts behind our full B2B product portfolio.
Opportunity
Flightradar24 is the world’s definitive source of flight data. While we lead the market in tracking the sky, our next frontier is to become the operational intelligence layer for the aviation industry.
We are transitioning from a data-provider to an essential operational partner. We don't just track flights; we provide the predictive insights that allow airlines, airports, and manufacturers to increase efficiencies, eliminate uncertainty and drive bottomline growth.
We are seeking a Tech Lead to be the founding engineer of our B2B tech-team. You will have a leading role in our transformation as we productise our raw data into B2B products. You will work together with our Sales team to define what we need to build. You will then take ownership of architecture and technology choices to deliver reliable, scalable and safe solutions. As we scale, you will have the opportunity to build a world-class engineering team.
The existing B2B portfolio includes, live data feeds, custom historical data exports, our public REST API service, and the business features of flightradar24.com. We have large volumes of ADS-B and other flight data, at different levels of granularity.
