Project:

Leading regional mobile network operator

We are looking for a
Voice AI Engineer (Real-time speech) to join our team!

Our client is an Azerbaijani telecommunications company and Azerbaijan's largest mobile network operator. The main products are:
Fixed telephony, Mobile telephony, Internet services, Wireless broadband, and Value-added services. The primary goal is to accelerate the client’s Data & AI initiatives via a secure, hybrid cloud foundation on AWS while systematically modernizing the IT estate as part of the AWS MAP 2.0 program.

Key Project Objectives include:

• Cloud Foundation & Landing Zone: Deploy target hybrid network architectures, establishing a secure AWS Landing Zone Accelerator (LZA) and hybrid Data/AI platforms on AWS.
• Security, Compliance & Sovereignty: Operationalize on-premises data de-identification and Format Preserving Encryption (FPE) tokenization (achieving zero raw PII in the cloud), fully adhering to Azerbaijani Personal Data Law No. 998-IIIQ and Critical Information Infrastructure Rules (Resolution No. 229).
• AI Chatbot & Real-Time Voicebot Implementation: Develop and operationalize a flagship Customer Care Voicebot (STT → LLM → TTS pipeline) and Agentic Chatbot targeting < 2.0s conversational voice latency and ~200 rps throughput as the first hybrid-setup consumer.

Responsibilities:

• Design, build, and operationalize end-to-end real-time STT → LLM → TTS (Speech-to-Text / LLM / Text-to-Speech) voicebot pipelines on AWS, optimizing for streaming speech-to-text, first-token LLM generation, and first-audio TTS synthesis.
• Deploy and maintain production customer-trained Whisper (Azerbaijani ASR) and Azerbaijani TTS models as low-latency real-time endpoints on Amazon Sage Maker and specialized GPU node pools (NVIDIA A100/L40S).
• Implement and manage the
  Bedrock Proxy Gateway on EKS for multi-model routing, priority queuing via Redis Sorted Sets, cost caps, and high-availability serving targeting ~200 rps without API throttling.
• Integrate voicebot and chatbot decision engines with core enterprise telephony and CVM platforms, including
  Avaya (voice telephony),
  Genesys (digital chat/omnichannel), and Pelatro (CVM offer decisioning and uplift models).
• Establish
  LLMOps & MLOps pipelines using Amazon Sage Maker Pipelines and MLflow for experiment tracking, model versioning, prompt/agent registries, automated evaluation harnesses, and RAG knowledge base retrieval.
• Build call and chat transcription pipelines to ingest, transcribe, and extract real-time insights (churn risk, dissatisfaction, intent, lead signals) into downstream decision layers.
• Enforce data sovereignty and privacy controls by integrating on-premises
  Format Preserving Encryption (FPE) and tokenization wrappers into ML pipelines so zero raw PII enters AWS cloud environments.
• Define NFR baselines, dialogue flows, voicebot persona, turn-taking, and fallback/escalation logic to guarantee conversational round-trip latency < 2.0 seconds.
• Automate ML deployment workflows using
  Git Lab CI/CD and Infrastructure-as-Code (
  Terraform or AWS CDK
  ), establishing observability and Fin Ops spend/anomaly monitoring via Amazon Cloud Watch and Splunk
  .

Requirements:

• 4+ years of hands-on experience with machine learning and Speech Processing with a primary focus on real-time conversational AI,
  ASR (STT), and TTS voice pipelines.
• Deep expertise with Amazon Sage Maker (real-time GPU inference endpoints, Pipelines, Feature Store, Model Registry) and Amazon Bedrock (Agent Core, Bedrock Guardrails, Knowledge Bases).
• Proven track record in streaming speech inference, speech synthesis, and low-latency audio processing.
• Strong experience in GPU optimization and containerized…
