Senior Software Engineer, Voice AI

Cloaked https://cloaked.com/ is a privacy startup dedicated to rebuilding consumer trust in how personal data is used. Our vision is to create an internet that serves the needs of its users, first and foremost - with individual privacy and opt-in at the core. Our product is a virtual “cloak” that you use as you visit any website - Facebook, Amazon, etc. It lets you choose to share all, some, or none of your private information based on your personal preference.

ABOUT THE ROLE

We’re looking for a Senior Software Engineer to to join the effort in leading and setting strategic direction of Call Guard, our AI call screening product. Call Guard intercepts unknown callers, runs a real-time AI conversation, and only rings users through if the call is legit - protecting them from the spam, scam, and AI voice-cloning wave. 50M+ calls screened to date.

You’ll own the technical roadmap end-to-end: real-time voice agent design, conversational latency, adversarial robustness against AI-generated callers, and the cloud infrastructure underneath. Long-term, this role grows beyond Call Guard. You’ll contribute across Cloaked’s engineering org and help shape how we build AI-native consumer products at scale.

WHAT WILL YOU DO?

• Lead the technical roadmap and architecture for Call Guard’s real-time voice AI stack

• Design and build production voice agents that converse with unknown callers, classify intent, and block scams autonomously

• Optimize real-time conversational latency end-to-end - from STT, through agent reasoning, to TTS

• Build defenses against adversarial AI callers, including voice-cloned attacks targeting our users

• Integrate and evaluate frontier models (LLMs, speech models, agent frameworks) for production use

• Own VoIP routing, telephony integration, and the cloud infrastructure that the voice agent runs on

• Collaborate with design, mobile, and product teams to ship voice experiences that feel effortless to end users

• Serve as the voice AI domain expert on the team, raising the engineering bar through code reviews, architecture discussions, and mentorship

• Help the team ship features faster and with fewer bugs by setting the technical standard for the product

• Actively leverage AI tools in day-to-day engineering work

• Contribute across engineering teams beyond Call Guard as the business scales

WHAT SKILLS AND EXPERIENCES WILL HELP YOU?

• Strong software engineering fundamentals - production systems, distributed systems, real-time infrastructure

• Hands-on experience building voice or conversational AI products in production

• Proficiency with modern voice AI stacks: STT (Whisper, Deepgram, etc.), TTS (ElevenLabs, Cartesia, etc.), real-time orchestration (LiveKit, Pipecat, or similar)

• Deep familiarity with LLMs and agent frameworks (LangChain, LlamaIndex, LangGraph, or equivalents) in production environments

• Experience optimizing for sub-second end-to-end latency in real-time systems

• Proficiency in Python and/or Go, with a track record of building scalable backend systems

• Experience designing and deploying secure, production-grade APIs

• Strong understanding of cloud infrastructure (AWS, GCP) and containerized deployments

• Track record shipping consumer products at scale

• Active daily use of AI coding tools (Cursor, Claude, Codex) with strong prompt judgment and tool selection instincts

WHAT’S NICE TO HAVE?

• Experience with telephony, VoIP, SIP, or carrier-level call routing

• Background in speech recognition, signal processing, or audio engineering

• Familiarity with adversarial ML, AI safety, or anti-fraud system design

• PII handling and sensitive data awareness

• Prior exposure to consumer privacy or security-focused products

• Experience with WebRTC or real-time media infrastructure

WHAT DO WE LIKE?

• Passion for security, privacy, and internet ethics

• Curiosity and constant learning at the frontier of voice AI and applied ML

• Strong analytical thinking with proactive problem-solving abilities

• Ownership mentality - comfortable holding the pen on technical direction

• Effective team player in high-velocity environments

• Comfortable mentoring and knowledge sharing across teams

• Experience in startups or growth-stage companies

• Interest in data tracking, analytics, and product instrumentation
