Role Overview

We're seeking a highly skilled Lead Speech Researcher with deep expertise in speech technologies and advanced NLP to join our growing AI research team. In this role, you'll work on building and optimizing machine learning systems that power intelligent audio and language-based solutions, contributing to next-generation AI products that prioritize privacy, performance, and scalability.

Key Responsibilities

- Build a real-time voice-to-text (ASR) pipeline using models like Whisper, wav2vec2, DeepSpeech, or custom speech models.
- Design and implement fraud detection logic based on transcribed speech, keywords, and intent patterns.
- Integrate telecom call metadata to generate a multi-signal fraud score.
- Optimize entire model pipeline for low-latency mobile inference (TFLite, ONNX, quantization).
- Collaborate with VoIP/backend engineers to analyze call behavior patterns.
- Contribute to future capabilities: audio fingerprinting, real-time call classification, and voice anomaly detection.
- Work closely with AI Product and MLOps teams for deployment, updates, and feedback-based iteration.

Required Technical Skills

- Experience with speech AI/ASR models like Whisper, wav2vec2, DeepSpeech, Kaldi, or Silero including fine-tuning for Indian voice patterns.
- Strong understanding of NLP techniques for fraud detection including fraud keyword spotting, masked text decoding, and intent classification.
- Ability to extract and analyze telecom metadata .
- Hands-on experience optimizing models using TFLite, ONNX, and applying quantization (post-training or QAT) for on-device inference.
- Proficient in Python, with deep experience in PyTorch or TensorFlow, and comfort working with NumPy, pandas, and real-time data pipelines.
- (Bonus) Exposure to VoIP protocols (SIP, RTP) or experience detecting audio tampering, speaker changes, or spoofing in call audio.

Qualifications

- Bachelor's or Master's degree in Computer Science, Electrical Engineering, Data Science, or a related technical field.
- Specialization or thesis work in speech processing, ASR, telecom analytics, or applied NLP preferred.
- Strong portfolio showcasing real-world speech/NLP applications, open-source contributions, or peer-reviewed publications.
- Alumni of top institutions (e.g., IITs, IIIT-H, IISc, BITS) or equivalent global research programs are highly preferred.

Experience

- 3 to 6+ years of hands-on experience in speech AI, NLP for fraud or intent detection, or telecom-related machine learning.
- Previous work in R&D/product roles at communication companies or telecom/VoIP-focused startups is a major plus.
- Experience building, deploying, and optimizing mobile-first ML models or inference engines for real-time applications.

Bonus if You Have

- Contributed to open-source projects like openai/whisper, mozilla/DeepSpeech, or Facebook's wav2vec2.
- Kaggle competition experience in speech or fraud detection, or published work in fraud defense / voice AI.
- Experience working on AI security, adversarial robustness, or real-time edge inference protection.
