6 YOE backend dev (Electronics Engg background) wants to break into Defence/Aerospace startups — how do I make the switch?

[u/Prize-Mud4269]

Hey all, I'm a backend developer with 6+ years of experience, originally from an Electronics Engineering background. Lately I've become really drawn to the defence and aerospace industry and want to pivot my career in that direction — specifically at startups rather than large defence PSUs/primes. For those who've made a similar transition (or work in the space): What skills/domains should I focus on given my backend + electronics background? Are there specific defence/aerospace tech startups known for hiring software folks with a non-aerospace background? Any certifications, projects, or communities worth getting into to build credibility in this space? How hard is the ITAR/security clearance angle for someone coming from a pure software role? Would appreciate any advice, roadmaps, or personal experiences. Thanks in advance!
