• Implement agent moderation and control mechanisms.  
• Add observability, logging, and debugging for AI behavior.  
• Reduce hallucinations and failure modes through system design.  
• Collaborate closely with product, design, and engineering teams.  
Required Qualifications & Skills: 
• Bachelors/Master Degree in Computer Science or related field from one of the premier 
ins tutes in India/Abroad. IIT/IIIT/ISI/RECs would be preferred.

• Strong debugging mindset for real-world AI failures.  
• Should be comfortable in working in fast-moving product environments.  
• Strong AI engineering background is a must. 
Strong Plus Points: 
• Voice agents, speech-to-text, text-to-speech, or telephony systems.
