Why this role?



t Infare, we build products that open doors to right decisions by the air travel industry. Since 2000, we have gathered and we keep collecting a massive amount of data and insights that allow airlines to understand and to react to competitor behavior.

As air travel is becoming an increasingly large and competitive industry, fare intelligence is of vital importance. For this reason, our tools and products have become of major interest to airlines and airports in the past years: in fact, we have 19 of 20 world’s largest airlines as our customers on top of 200+ other carriers, and our business has been growing by 30-50% in recent years.

Data is at the core of our business, as we use it for our final products such as Pharos, Altus and others. However, we need to gather the data from APIs and/or extract it from airline websites, meta search and online travel agent sites. This is where our 30+ data collection team is crucial. Its members write, optimize, maintain and improve 1000+ of our robots/crawlers, and overcome challenges such as volume, quality, dynamism and even blocking on the daily basis. While we seek quality, integrity and consistency in the data we deliver to our customers, the funniest part about data extraction is that there’s no single rule or method to collect it: the solution is custom every time and it’s our engineers who have total liberty to come up with it!

As our company is going through an exponential growth, we decided to transform our backend to use all the newest and coolest technologies that are out there. You will use infrastructure as a code and work closely with development teams to automate deployment. Your team will ensure running of physical Data Centers and Public Cloud.
