About the Job

Requirements

  • A bachelor's degree in electrical engineering, aerospace, mechanical engineering, or a similar technical field is required.
  • At least 2 years of professional, internship, academic, or project-based experience testing real hardware, including electronics, electromechanical systems, or similar; coursework, internships, and serious personal projects count.
  • Ability to read and interpret schematics, layouts, and bills of materials; mechanical drawing skills are a plus.
  • Hands-on experience with common test equipment such as multimeters, oscilloscopes, and power supplies, and basic component-level troubleshooting ability.
  • Familiarity with printed circuit board assembly or electronics testing and/or environmental, qualification, or integration testing.
  • Ability to learn, ask questions, take ownership of outcomes, and troubleshoot in the field.

Responsibilities

  • Build, run, and improve test setups and procedures for aircraft hardware, including avionics, power systems, sensors, and electromechanical assemblies, at the bench and system level.
  • Perform incoming inspection and bring-up of electronics, including printed circuit board assemblies and commercial off-the-shelf components, and mechanical assemblies; troubleshoot issues to their root cause.
  • Run environmental and qualification testing, including thermal, vibration, and altitude/vacuum testing, to verify that hardware survives the stratosphere.
  • Develop hardware-in-the-loop and automated test setups to accelerate engineering iteration loops.
  • Support calibration of test and development assets and maintain reliable test equipment.
  • Capture and analyze test data, document results, disposition non-conformances, and drive corrective actions and product improvements.
  • Review schematics, layouts, bills of materials, drawings, and work instructions, and help create clear test documentation.
  • Support integration, production bring-up, and flight testing in the field.

About the Company

Icarus

Solar-powered stratospheric aircraft for ISR

Icarus builds APOLLO, a solar-powered autonomous aircraft that aims to fly continuously in the stratosphere (above 60,000 feet) for weeks without landing. It covers more than 1,000 square miles with ultra-high-resolution, real-time sensing and delivers high-throughput, low-latency connectivity directly to ground devices. This platform is positioned as a cost-effective, rapidly deployable alternative to satellite constellations for persistent intelligence, surveillance and reconnaissance (ISR) and resilient communications, with a primary focus on defense and security customers. Founded in 2023 and based in Los Angeles, Icarus was part of Y Combinator's Fall 2025 batch.
