AI/ML Engineer – LLM & Voice Pipeline

Apply for AI/ML Engineer – LLM & Voice Pipeline in Remote India

Project description

Our client is advancing its in-vehicle voice assistant into an intelligent, AI-powered companion. Since 2024, they have been incorporating large-language-model capabilities (Azure OpenAI / ChatGPT) into vehicles equipped with the MIB3 infotainment system, with new E³-architecture models featuring enhanced voice functions from the factory. The AIME (AI Model Engine) backend program supports this development over a multi-year timeline, addressing natural-language dialogue, empathic communication, and the complete cloud-edge data pipeline. DXC Luxoft serves as the end-to-end delivery partner, collaborating closely with the client’s engineers within a joint product team on the Azure platform (AKS, Azure OpenAI, Managed Identity, Azure Monitor, Azure DevOps).

Responsibilities

• Design, implement, and optimize RAG pipelines integrating Azure AI Search, vector stores, and LLM completion endpoints.

• Develop and maintain ASR and TTS integration modules, including audio pre

• and post-processing using pyAudio and librosa.

• Create LLM prompt chains, evaluation frameworks, and safety/alignment guardrails for in-vehicle dialogue scenarios.

• Prototype AI capabilities such as few-shot adapters, intent classification, and empathic dialogue, then transition prototypes to production.

• Collaborate with Backend Engineers to develop the FastAPI/Kafka interface connecting the AI layer with the streaming infrastructure.

• Contribute to edge AI components including on-device inference, model quantization, and latency management for in-vehicle use.

• Monitor and enhance model quality metrics including BLEU, WER, CER, and faithfulness via continuous evaluation pipelines.

• Participate in code reviews with cross-functional teams, including customer ML engineers.

Skills

• Must have

• 3+ years of hands-on AI/ML engineering in production environments.

• Strong Python skills; experience with LLM frameworks: LangChain, LangGraph, or equivalent.

• Practical experience building RAG systems (chunking strategies, embedding models, retrieval evaluation).

• Familiarity with Azure OpenAI Service or OpenAI API; prompt engineering best practices.

• Experience with at least one ASR engine (Whisper, Azure Speech, or equivalent) and a TTS system.

• English B2 or above.

• Nice to have

• pyAudio / librosa audio signal processing.

• Edge inference: ONNX, TensorRT, or on-device model deployment.

• Automotive in-vehicle speech processing context (noise cancellation, far-field microphones).

• Experience with LLM evaluation frameworks (DeepEval, Ragas, PromptFlow).

• German language skills.
