About Vakta AI

Vakta AI is building a bold new interface to knowledge — through hyper-realistic AI avatars that people can talk to, learn from, and take guidance from in real-time.

From intelligent tutors and language coaches to career, legal, and health advisors — we're rethinking how India learns and solves problems, one conversation at a time.

We’re assembling a world-class AI team to push the frontiers of LLMs, speech technology, and virtual agent design — blending cutting-edge research with real-world scale.

As part of this journey, we’re hiring across core AI/ML roles — a rare chance to shape the future of avatar-based learning and expert access for millions across Bharat.

What You’ll Work On

Core R&D

Fine-tune and optimize LLMs (Mistral, Gemma, Phi, etc.) for interactive, role-based conversations

Build voice-driven interfaces using models like Whisper, Bark, OpenVoice, etc.

Experiment with LoRA, QLoRA, RAG, quantization, and other performance techniques

Engineering & Deployment

Convert research into production-grade APIs or on-device models

Optimize models for latency, memory, and multilingual support

Integrate models with 3D avatar systems and real-time user experiences

Internal Knowledge Sharing

Maintain clean experiment logs and model documentation

Collaborate in internal demos, peer reviews, and quick iteration cycles

You Should Have

1–2 years of experience in AI/ML, NLP, or speech tech — or strong project portfolio

Proficiency with PyTorch, Transformers, HuggingFace, and model fine-tuning

Familiarity with LLM training techniques like LoRA, DPO, RAG, or quantization

Hands-on experience with speech technologies (ASR/TTS) is a strong plus

Clear communication and the ability to own projects end-to-end

Bonus If You’ve Worked On

Indian language support / multilingual AI

ONNX, model compression, or edge deployment

Unity, WebXR, or avatar integration pipelines

Open-source contributions or public demos/projects

Qualifications

Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, Machine Learning, Data Science, or related fields

Strong academic or project background in NLP, deep learning, or speech processing

Alternatively, a solid portfolio of personal/independent work in LLMs or applied ML can substitute for formal education
