WE ARE SEEKING software developers and embedded engineers with 4+ years of experience. At Sparx you will work with clients on projects involving everything from embedded microcontrollers, to media and image processing, to Bluetooth and TCP communications, to server-side database, web, and mobile app development. Our engineers work across C and C++ on bare-metal and RTOS targets, VHDL for FPGA designs, Embedded Linux with Yocto or Buildroot, Python for tooling, test automation, and data analysis, and C# and .NET for desktop applications and services. As such, you should have a proven track record of being able to pick up new languages and technologies, be multi-faceted in your skillset and interests, and preferably have some history of "tinkering" in your spare time.
We operate across many fields such as aerospace, oil and gas, medical, robotics, industrial automation and consumer products. You will be exposed to many types of technology and have the opportunity to hone your current expertise and learn skills both within and outside of the software engineering spectrum, such as electronics and advanced data analysis.
