We're looking for a Senior Software Engineer to join the Call Guard team and help build the next generation of our real-time voice AI. You'll own major parts of the stack, from voice agent design and conversational latency to adversarial robustness and the infrastructure underneath. Call Guard is Cloaked's AI call screening product. It intercepts unknown callers, holds a real-time AI conversation with them, and only rings the user through if the call is legit.
