About Trovex.ai

Trovex.ai is an AI-powered Sales Readiness and Performance Enablement platform that helps enterprises build, assess and improve the capabilities of their frontline sales teams.

Our platform leverages conversational AI, voice technologies, generative AI and digital avatars to create realistic role-play simulations, personalized coaching experiences and AI-powered learning solutions.

We work with leading enterprises across BFSI and other industries, helping thousands of sales professionals improve their real-world performance.

About the Role

We are looking for curious and hands-on AI Engineering Interns who are passionate about building applications using Large Language Models (LLMs), Speech-to-Text (STT), Text-to-Speech (TTS) and AI-powered digital avatars.

You will work closely with our engineering and product teams to experiment with emerging AI technologies, build prototypes and develop production-ready features that power our conversational AI platform.

This is an opportunity to work on real-world AI products rather than just research projects or proof-of-concepts.

Key Responsibilities

- LLM Integration: Build applications using LLMs such as OpenAI GPT, Google Gemini, Claude and open-source models.
- Voice AI: Experiment with and integrate Speech-to-Text (STT) and Text-to-Speech (TTS) technologies to enable natural, real-time voice conversations.
- AI Avatars: Explore and integrate AI avatar technologies for realistic, interactive digital human experiences.
- Conversational AI: Develop AI-powered conversational agents,



role-play simulations and intelligent virtual assistants.
- Prompt Engineering: Design, test and optimize prompts, system instructions and conversational workflows.
- Backend Development: Build APIs, integrate AI services and develop backend components for AI-powered applications.
- Experimentation: Evaluate new AI models, frameworks, APIs and tools, and identify opportunities to improve product capabilities, response quality, latency and cost.
- Prototyping: Rapidly build functional prototypes and convert successful experiments into scalable product features.

- Required Skills & Qualifications

- Strong programming fundamentals in JavaScript/TypeScript or Python.
- Basic understanding of LLMs, Generative AI and prompt engineering.
- Hands-on experience using APIs from OpenAI, Gemini, Claude or similar platforms.
- Familiarity with REST APIs, JSON and backend development.
- Understanding of basic concepts in machine learning and NLP.
- Familiarity with Git/GitHub and collaborative development practices.
- Strong problem-solving skills and a willingness to learn new technologies.

Good to Have

Experience or familiarity with any of the following:
- LLM Frameworks: LangChain, LangGraph, LlamaIndex,



Hugging Face.
- STT/TTS: Google Speech-to-Text, Deepgram, ElevenLabs, Azure Speech Services or similar.
- AI Avatars: HeyGen, D-ID, Tavus, Simli or similar avatar platforms.
- Voice AI Frameworks: LiveKit, Vapi, Pipecat or real-time audio processing.
- AI Infrastructure: Google Cloud Vertex AI, AWS Bedrock or Azure AI.
- Development Stack: Node.js, React.js, Express.js, MongoDB.

You don't need to know all these technologies. We value hands-on experimentation, curiosity and the ability to build things.

What You Will Get

- Work on real-world AI products used by large enterprises.
- Hands-on exposure to cutting-edge LLM, Voice AI and Digital Avatar technologies.
- Opportunity to work with experienced engineers and product leaders.
- Experience building and deploying production-grade AI applications.
- Freedom to experiment with current AI tools, models and frameworks.
- Potential opportunity for a full-time role based on performance and business requirements.

- Who Should Apply? We are looking for builders and problem-solvers who enjoy experimenting with technology, learning independently and turning ideas into working products.

Students pursuing B.Tech, B.E., M.Tech, MCA or related degrees in Computer Science, Information Technology or equivalent disciplines are encouraged to apply.

Most importantly, show us something you have built! Personal projects, GitHub repositories, hackathon projects and AI experiments will be given significant weightage.
