Frequently asked questions
Do I need a security clearance for Anduril FDE?
Not always, but it helps significantly. Anduril can sponsor clearances, but active clearance holders move faster through the process.
Is Anduril FDE open to software engineers without defense experience?
Yes, but mission alignment is non-negotiable. If you're not genuinely interested in national security and defense technology, it will show.
What programming languages does Anduril use?
C++ for systems-critical code, Python for tooling and data work. Some teams use Rust. Know your fundamentals well.
How is working at Anduril different from other FDE roles?
The operational context. You may be on a military base, in a field environment, or working with classified systems. The stakes feel much higher.
