Put drone jobs back into the five-layer supply chain and the picture clarifies: Layer 2 belongs to mechanical and electrical engineers, while Layer 3 — flight control firmware, sensor fusion, RF, edge AI — is the real entry point for software people, and also exactly the layer Taiwan is short on. But check the scale first: 267 companies and NT$12.9B of 2025 output means far fewer openings than the news volume suggests.
TEDIBOA has grown from 50 founding members to over 260, but since 1 July 2025 you must first be a full member of the Defense Industry Development Association before you can even apply. R&D grants under the Industrial Innovation Platform cap out at 50% of total project cost, three concurrent cases per company, three years maximum — and explicitly ban red-supply-chain components while requiring joint cybersecurity lab testing. This piece covers only what public documents can actually establish.
PX4's own architecture docs say the companion computer runs Linux because 'Linux is a much better platform for general software development than NuttX; there are many more Linux developers.' That sentence is the entry point. The three transition paths differ sharply in friction — CV and MAVLink work on the companion computer transfers almost directly, flight controller firmware means learning RTOS and work-queue constraints, and estimation and control means quaternions and Kalman filters.
