Job description

We are seeking a highly skilled and motivated AI Engineer to design, develop, and deploy advanced solutions using Large Audio Language Models (LALMs) and end-to-end Speech-to-Speech (S2S) systems. This role focuses on building real-world, production-ready applications that integrate speech recognition, language understanding, and speech synthesis into seamless voice-driven experiences.

You will work at the intersection of AI, deep learning, and speech technologies, contributing to innovative products rather than purely theoretical research.

Key Responsibilities
  • Design and implement end-to-end speech-to-speech systems integrating ASR, LLMs, and TTS components
  • Develop and optimize Large Language Models (LLMs) and Large Audio Language Models (LALMs) for real-world applications
  • Build scalable pipelines for speech and language data processing, including data collection, augmentation, and preprocessing
  • Fine-tune models on domain-specific datasets to improve performance and contextual accuracy
  • Evaluate and benchmark voice agents using modern frameworks and real-world conversational data
  • Apply prompt engineering techniques to enhance model responses and system behavior
  • Integrate AI models into backend systems and deploy them in cloud environments
  • Collaborate with cross-functional teams (product, engineering, and research) to deliver production-grade solutions
  • Continuously optimize models for latency, scalability, and quality (speech intelligibility and language accuracy)
Required Qualifications
  • Master’s or PhD (or equivalent experience) in Computer Engineering, Artificial Intelligence.Strong programming skills in Python.
  • Hands-on experience with deep learning frameworks such as TensorFlow or PyTorch
  • Solid understanding of neural networks and deep learning techniques for speech and language processing
  • Expertise in Large Language Models (LLMs), speech recognition (ASR), and text-to-speech (TTS) systems
  • Experience with end-to-end speech-to-speech architectures and multimodal AI systems
  • Knowledge of prompt engineering and model fine-tuning techniques
  • Familiarity with tools and frameworks such as LangChain, LangGraph, or similar orchestration tools
  • Experience with backend systems, APIs, databases, and containerization (e.g., Docker)
Preferred Skills
  • Experience with evaluation frameworks for voice agents (e.g., EVA or similar tools)
  • Strong understanding of model evaluation metrics for speech quality, accuracy, and contextual relevance
  • Experience handling large-scale datasets and building efficient data pipelines
  • Knowledge of speech data augmentation techniques
  • Ability to rapidly learn and apply emerging AI technologies
Core Competencies
  • Strong problem-solving and optimization skills
  • Hands-on, product-focused mindset with a passion for building real-world AI solutions
  • Attention to detail, with a structured and methodical approach to development and documentation
  • Strong communication and collaboration skills across technical and non-technical teams
  • Ability to work independently while contributing effectively in a team environment
Why Join Us?

This is a unique opportunity to work at the forefront of AI innovation, shaping the future of speech-to-speech systems and intelligent voice applications. You will play a key role in building next-generation AI products that have real-world impact.
