From Non-CS to Defense Tech: Beginner’s Guide to Sensor Fusion Embedded Systems Interviews

Mistakes to Avoid

BAD: “I’d just average the two sensor streams.”
GOOD: “I’d implement a weighted Kalman filter, respecting the 2 Mbps SPI bus and the 5 ms latency budget.”

BAD: “Security isn’t my concern; the hardware is sealed.”
GOOD: “I’d enforce AES‑256 encryption and follow Palantir’s GIST framework to protect classified links.”

BAD: “My PhD in robotics proves I’m ready for defense.”
GOOD: “My hands‑on work on the Raytheon missile‑guidance prototype taught me to manage cross‑modal interference under strict timing constraints.”

FAQ

Is a non‑CS degree a deal‑breaker for defense sensor‑fusion roles? No. The Q2 2024 Lockheed Martin senior‑engineer hire showed that domain experience and a proven ability to discuss bus limits can outweigh a lack of CS coursework.

What is the most decisive question in a sensor‑fusion interview? The question that forces the candidate to address the real‑time bus limitation—e.g., “How will you handle a 2 Mbps SPI bus while fusing 10 Hz IMU and 30 Hz radar data?”—has historically determined the debrief vote.

How should I negotiate salary after a successful loop? Reference the internal compensation band disclosed on May 12 2024 (e.g., $175‑$185 K base) and emphasize equity; attempts to push base above $200 K without a CS doctorate have been rejected in past Lockheed Martin negotiations.amazon.com/dp/B0GWWJQ2S3).
