What You'll Do

• Lead the technical architecture for AI-powered voice and speech applications.

• Evaluate and recommend AI models for different use cases such as speech recognition, transcription, translation, summarization, and conversational AI.

• Design and build scalable backend services using Java and Python.

• Work with Azure AI services, including Azure Voice Live API, Speech Services, and Azure OpenAI.

• Design low-latency, real-time speech processing pipelines.

• Collaborate with product, engineering, and AI teams to deliver production-ready AI solutions.

• Drive technical decisions around model selection, performance, latency, scalability, and cost optimization.

• Mentor engineers and promote engineering best practices across teams.

Required Qualifications

• Bachelor's or Master's degree in Computer Science or a related field.
