This is a high-visibility, high-impact opportunity perfect for analytical, curious individuals who want to contribute meaningfully from Day 1.
Key Responsibilities :
- Train, fine-tune and deploy AI/ML models for use cases like speech recognition, speaker isolation, turn detection across languages and verticals
- Build scalable inference pipelines and integrate models seamlessly into production environments
- Optimize models for latency, accuracy and throughput because this is real-time, global-scale AI
- Analyze large datasets to identify patterns, surface improvements and drive model performance
- Collaborate cross-functionally with engineering, product and data teams to deliver production-ready AI features
- Explore and implement open-source frameworks, build internal AI tooling and stay ahead of the curve
- Stay current with the latest trends in LLMs, generative AI and voice intelligence because we’re always pushing the frontier
What We’re Looking For :
- B.Tech in Computer Science, AI/ML, Data Science or a related field from a top engineering school
- Strong theoretical understanding of ML algorithms, deep learning and model training
- Proficiency in Python and experience with frameworks like PyTorch, TensorFlow or Hugging Face Transformers
- Hands-on experience building models (e.g., NLP, ASR, TTS, embeddings, voice agents); Kaggle or competition experience is a strong plus
- Solid experience in data processing, feature engineering and model evaluation techniques
- Analytical mindset, bias for action and excellent communication and collaboration skills
Nice to Have :
- Experience working in real-time systems and deploying models in production
- Familiarity with MLOps tools and pipelines
- Exposure to speech, voice or multimodal datasets
- Contributions to open-source ML projects
- Experience building models from scratch
Why Join Plivo?
- You’ll build AI models that power global-scale products used by top B2C brands
- You’ll work with real speech and language data at a massive scale
- You’ll join a fast-paced engineering culture with high ownership and internal autonomy
- You’ll be at the intersection of real-time systems and AI - rare and exciting
- You’ll be part of a culture that values innovation, experimentation and real business impact
