AI Engineer developing AI agents and intelligent software components for a top software solutions provider in retail and hospitality. Collaborating with teams to enhance user experiences and internal processes.
About the role
- Senior AI Engineer leading voice technology stack evolution for US Mobile. Spearheading Voice Biometrics and AI Agents development for advanced connectivity solutions.
Responsibilities
- Establish the Trust Layer: Design and deploy robust voice biometric systems (Speaker Verification and Identification) to serve as the secure entry point for our voice ecosystem.
- Anti-Spoofing & Security: Develop advanced liveness detection and anti-cloning models to protect against deepfakes and synthetic audio attacks.
- Architect Voice AI Agents: Lead the long-term transition toward autonomous Voice Agents by integrating Biometrics with ASR, TTS, NLU and LLMs.
- Pipeline Innovation: Build end-to-end low-latency pipelines that process streaming audio, enabling fluid, real-time "human-in-the-loop" or fully autonomous interactions.
- LLM Integration: Explore and implement Large Language Models (LLMs) and "Speech-to-Speech" architectures to give our voice agents contextual memory and reasoning capabilities.
- Performance Engineering: Optimize models for accuracy (minimizing FAR/FRR) and latency, ensuring the agent responds with sub-second "Time to First Token."
Requirements
- 6+ years of experience in AI/Machine Learning, with a strong portfolio in Speech Processing or Audio Intelligence.
- Biometric Expertise: Proven experience in speaker recognition, embedding extraction (x-vectors/d-vectors), and signal processing.
- Conversational AI Vision: Deep understanding of the modern "Voice Stack"—specifically how to connect ASR, LLMs, and TTS into a cohesive agentic workflow.
- Tooling & Frameworks: Expert-level proficiency in PyTorch or TensorFlow, and familiarity with speech libraries such as SpeechBrain, NVIDIA Riva, or Kaldi.
- Production Excellence: Experience deploying real-time AI models in cloud environments (AWS/GCP/Azure) with an emphasis on high-availability and security.
- Growth Mindset: A background in general AI with the agility to master niche voice biometrics today and lead broad Voice AI agent strategy tomorrow.
Benefits
- Competitive salary
- Flexible working hours
- Supplemental health insurance
- Professional development stipend
- $500 wfh tech set-up reimbursement
