IoT Software Developer (ADS-B & Mode S)

IoT Software Developer (ADS-B & Mode S)

Flightradar24 is looking for a talented developer to lead the software development of our terrestrial receiver network that receives, interprets and distributes data from aircraft transponders including ADS-B and Mode S.

We operate a network of many thousands of receiver devices globally, including our own hosted hardware in addition to volunteers with a variety of hardware, including Raspberry Pi. This network is continuously growing as we bring new receivers online to expand our coverage and today delivers hundreds of millions of data frames every hour.

What you’ll do

  • Develop and maintain Flightradar24's IoT receiver software using modern C++ in order to continue improving our flight tracking coverage and features
  • Develop and maintain server-side software in C++ and Python for large-scale processing of incoming data from the receiver network
  • Apply analytic, algorithmic and signal processing skills to solve software design problems
  • Use your own initiative to drive the receiver roadmap through research of experimental ideas and recommending key improvements and features
  • Liaise closely with the electrical engineering team to improve receiver hardware and coordinate the software support of new hardware

Who you are

  • You have significant experience with modern C++ development for Linux and online services, ideally also in environments processing lots of data
  • Familiar with common flight tracking hardware and software such as the Mode-S beast, RTL-SDR USB devices and dump1090
  • Active interest in aviation interrogation standards including multilateration (MLAT), ADS-B (ES plus UAT), Mode S (DF17, DF18 etc), Mode A/C and more
  • You have experience employing development best practices, such as test-driven development, unit testing, code reviews, continuous integration, etc.
  • You know how to design simple, performant, testable, and maintainable software
  • Proficient in using technical and aviation (e.g. ICAO) documentation
  • Comfortable working with semi low-level development for e.g. Raspberry Pis
  • Experience with web development and web frameworks, e.g. for collecting and presenting statistics, would be a plus
  • Excellent English skills – Swedish is not required for this role
  • An aviation geek, and quite possibly already a user or feeder of Flightradar24's services and network :-)
