As a Senior Data Engineer, you will be responsible for developing next generation data pipelines for IoT wearable devices. We are seeking an engineer with many years of experience in the domain, proficient at SDLC and engineering cycles.  You have deep experience with the big data software stack(s). You are up to the challenge of evolving StrongArm’s big data systems, scaling these to hundreds of thousands of industrial athletes, and leveraging advanced techniques like ML edge computing, geolocation analysis, and computer vision.

You must be able uphold quality engineering principles and enjoy holding responsibilities solving advanced problems.

We are highly collaborative. Our open office environment is people-focused - we joke, have fun, and enjoy each other's company when we can, but aren’t afraid to roll up our sleeves and get things done. We are looking for driven and open-minded engineers with exceptional analytical abilities who can wear a number of hats from data engineering, dev-ops, software design, software development, system administration and system architecture.



  • Individual contributor using Python with a system trajectory towards Scala
