Icarus median: 30 days open

The posting

Icarus was founded on the belief that the Stratosphere is the Forgotten Frontier and that reclaiming it will define the next era of aerospace and what is possible from the sky. We build solar-powered aircraft that fly at 60,000 ft for weeks at a time, delivering persistent, affordable, and scalable presence from this layer of the atmosphere.

Mission

Re-establish and maintain dominance in the Stratosphere.

What you’ll do

  • Design, build, and fly RF and communications systems for long-endurance stratospheric aircraft
  • Own RF subsystems end to end: architecture, link budgets, component selection, integration, test, and flight validation
  • Design and integrate radios, antennas, RF front ends, and data links for LOS and BLOS operation
  • Drive RF performance through analysis, simulation, bench testing, and flight data
  • Lead EMI/EMC mitigation across avionics, power, and payload systems
  • Work closely with avionics, GNC, electrical, mechanical, and software teams to deliver robust flight communications
  • Support integration, production bring-up, and flight operations in the desert

What we’re looking for

  • 2+ years designing and deploying real RF systems for aerospace, defense, UAVs, or similarly demanding environments
  • Strong fundamentals in RF theory, electromagnetics, and communications systems
  • Experience with link budgets, antenna design or selection, RF propagation, and system-level trade studies
  • Hands-on experience with RF test equipment (spectrum analyzers, VNAs, signal generators, power meters)
  • Experience debugging RF systems in the field, not just in simulation
  • Comfort working from first principles and validating performance through test and flight data
  • Ability to move fast, own outcomes, and operate with minimal supervision

Why Icarus

  1. Meaningful equity
  2. Top market salary and bonuses
  3. Health, dental, and vision insurance
  4. Factory in El Segundo
  5. Real ownership, real hardware, real flight
  6. Small team, massive responsibility
  7. High signal (engineering) to noise (management) culture
  8. Dream desk setup
  9. Daily lunch
  10. Unlimited celsius

This is not a normal engineering job

  1. We are pioneers, not corporate managers. Icarus deliberately optimizes for a high signal (engineers) to noise (management) ratio, where engineering, flight, and execution matter more than process, politics, or management overhead
  2. You will work side by side with the CEO and a small team of world-class builders. You will own your subsystem end to end. Design it. Build it. Break it. Fix it. Validate it in the desert. Fly it. Then do it again, faster
  3. We expect full extreme ownership. This is a high-trust, no-BS team, and everyone pulls their weight
  4. We are hiring across the stack: mechanical, aerodynamics, RF, GNC, electrical, avionics, power electronics, energy storage, software, and systems
  5. We want builders. No hand-holding. No fluff. No fake projects. No slide decks. No sitting in meetings all day. Just raw engineering, real hardware, and real flight
  6. You must thrive under pressure, learn fast, troubleshoot in the field, and push hardware to its limits. We move fast. We go to Mojave at 4 am in the morning. We expect results and an obsession with quality and speed
  7. You will be a core executor of flight systems, taking them from concept to reality and driving rapid iteration loops. You will work across design, integration, testing, and flight. If you want real ownership, real hardware, and real flight milestones, this is it.

No tourists. No bystanders. Only builders.

Hiring process

  1. Technical interview
  2. One-on-one with CEO
  3. Meet the team in-person

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
