Senior Software Engineer, Voice AI
About The Position
Cloaked is building the next generation of its real-time voice AI for the Call Guard team. This role involves owning major parts of the stack, from voice agent design and conversational latency to adversarial robustness and the underlying infrastructure. The engineer will contribute to AI-native consumer products and help build the agents that turn detection into action. Call Guard is Cloaked's AI call screening product that intercepts unknown callers, engages them in an AI conversation, and only connects legitimate calls, stopping spam, scams, and voice-cloned callers. We have screened over 50 million calls to date.
Requirements
- 5+ years building production software, ideally real-time or distributed systems
- Hands-on experience shipping voice or conversational AI products in production
- Fluency with modern voice AI stacks: STT (Whisper, Deepgram), TTS (ElevenLabs, Cartesia), and real-time orchestration (LiveKit, Pipecat, or similar)
- Production experience with LLMs and agent frameworks (LangChain, LangGraph, LlamaIndex, or equivalents)
- Experience optimizing for low latency in real-time systems
- Strong Python and/or Go, with experience building scalable, secure backend systems and APIs
- Solid cloud infrastructure experience (AWS or GCP, containerized deployments)
- Experience shipping consumer products at scale
- Daily use of AI coding tools (Cursor, Claude, Codex) with good judgment on when and how to use them
Nice To Haves
- Telephony, VoIP, SIP, or carrier-level call routing experience
- WebRTC or real-time media infrastructure experience

- Familiarity with adversarial ML, AI safety, or anti-fraud systems
- Experience handling PII and sensitive data
- Prior work on consumer privacy or security products
Responsibilities
- Design and ship production voice agents that talk with unknown callers, classify intent, and block scams autonomously
- Own key components of Call Guard's real-time voice AI stack and contribute to its architecture and technical direction
- Drive down end-to-end conversational latency across STT, agent reasoning, and TTS
- Build defenses against adversarial AI callers, including voice-cloning attacks targeting our users
- Evaluate and integrate frontier models (LLMs, speech models, agent frameworks) for production use
- Build and maintain telephony, VoIP routing, and the cloud infrastructure the voice agent runs on
- Partner with product, design, and mobile to ship voice experiences that feel effortless
- Raise the team's bar on quality through code reviews, design discussions, and knowledge sharing
- Use AI tools daily to move faster
