Second Order Effects is an engineering consultancy based in El Segundo, California. Founded in 2016, we provide technical consultation, electrical design, product development, and testing services for clients across multiple industries. Our mission: We design and create effective engineering solutions by improving our methods and building traditions. Engineering is a craft that is honed and mastered through coaching and practice, and employees receive deep training in their respective areas of expertise. We design, build and test precisely — reaching the right solution rather than the easiest, turning uncertainty into functional hardware and software, and picking up new knowledge along the way. Our value: We help our customers reduce their development risk, expand their capabilities, and increase their engineering bandwidth. Our solutions are low overhead and turnkey, even for the most complex of projects. We get it right. Our designs have become parts of rocket engines, satellites, self-driving cars, automated systems, and consumer electronics of all kinds. Our hardware is sold in Apple stores and lives in outer space.

HW Test Software Engineer

HW Test Software Engineer

As a Hardware Test Software Engineer you will own all aspects of software development for automated hardware test systems. This includes creating software and tools for the development of hardware, simulation environments, continuous integration setups, and hardware-in-the-loop (HITL) and hardware-out-of-the-loop (HOOTL) systems. You will be responsible for the complete life-cycle of the software you create, from initial concept through release.


  • Develop automation frameworks and invent new tools that enable more frequent and reliable software deployment, test execution, and data analysis as part of our continuous integration and release system
  • Create and test code for aerospace, automotive, and consumer electronics projects (including rockets, satellites, robotic systems and more!) using simulated hardware, HITL/HOOTL systems, and a variety of testing environments
  • Perform hands-on integration and troubleshooting of hardware/software systems
  • Analyze test results and root cause bugs that require in-depth investigations by monitoring real-time output and data review tools
  • Provide meaningful contributions to clients for environmental test systems and help drive decisions for projects in a variety of different industries
