Flight Test Engineer

The Flight Test Engineer designs and executes flight test campaigns for high-altitude solar-powered aircraft, oversees real-time test execution, analyzes telemetry data to characterize performance, and drives design improvements through reports and root cause analysis. Requires aerospace/mechanical engineering degree, flight test experience, strong data analysis skills in MATLAB/Python, and willingness to travel to remote test sites.

About the job

What you’ll do

Plan the test

  • Design flight test campaigns, test cards, and pass/fail criteria from first flight through envelope expansion.
  • Define what we measure: instrumentation, sensors, data acquisition, and telemetry requirements.
  • Write test plans and hazard analyses, and contribute to flight safety documentation.
  • Translate engineering questions into test points that can effectively find an answer.

Oversee the test

  • Oversee execution of test cards and test criteria during test events, making sure each point is flown and captured correctly.
  • Monitor aircraft behavior and data in real time against the test criteria.
  • Recommend and make parameter changes when the test calls for it, in coordination with the test director and flight crew.
  • Capture the conditions, configuration, and events of every flight with precision.

Turn data into answers

  • Own the data: build and maintain the pipeline and tooling that turn raw flights into clean, usable engineering data.
  • Analyze flight data and telemetry to characterize aircraft performance, stability, loads, and systems behavior.
  • Run root cause analysis on anomalies and failures and drive them to resolution.
  • Write quick-look and formal test reports that engineering trusts and acts on.
  • Compare flight results against models and predictions and close the loop with the design teams.

Improve the test program

  • Continuously improve the tools, processes, and standards that make Icarus flight test fast, safe, and repeatable.
  • Travel to remote test sites and work in heat, cold, wind, and dust for long days on short notice.

What we’re looking for

  • Bachelor's or graduate degree in aerospace, mechanical, electrical, or a related engineering discipline.
  • Experience in flight test, developmental test and evaluation, or a closely related discipline.
  • Demonstrated experience planning and executing flight test, ideally including first-flight or build-up test programs.
  • Familiarity with flight test fundamentals, ideally fixed-wing: test card design, envelope expansion, and test criteria.
  • Strong data analysis skills: you can turn large, messy flight data sets into clear engineering conclusions.
  • Proficiency in MATLAB, Python, or similar for data analysis, signal processing, and scripting.
  • Strong Linux command line skills for debugging and troubleshooting.
  • Working knowledge of instrumentation, telemetry, and data acquisition.
  • Calm, decisive judgment under pressure, especially when jumping in on parameters with an aircraft in the air.
  • Willingness to travel to remote test sites.
  • Strong communicator, non-negotiable.
  • High trust, extreme ownership, no ego.

Bonus

  • Experience as a test director or test conductor, running test events and directing the flight crew.
  • FAA Part 107 Remote Pilot Certificate or experience operating unmanned aircraft.
  • Background building RC or UAS aircraft (SAE Aero, Design Build Fly, or serious hobbyist).
  • Experience working within a flight test program at an early-stage company.
