Core Values

Role Summary

You’ll help build the Intelligence Engine: the learning layer of our platform that improves itself over time

using data, experiments, and models. This role is for people who don’t just run notebooks — they ship

outcomes.

• Build and improve foundational ML models powering discovery, ranking, relevance, and conversion signals.
• Curate datasets (structured and unstructured), define labeling strategies, and own feature/model iterations end-to-end.
• Run model experiments: offline evaluation, online experimentation (A/B), and rapid iteration loops.
• Design evaluation frameworks for LLMs, embeddings, retrieval, and agent decisioning, including human-in-the-loop checks where needed.
• Partner tightly with Product and Engineering to translate ambiguous problems into measurable model wins.

Technical Requirements (What you should be strong at)

• Model training: classical ML and deep learning (PyTorch/TensorFlow), loss functions, regularization, calibration, bias/variance trade-offs.
• Representation learning: embeddings, metric learning, retrieval, similarity search, vector databases (or equivalent).
• LLM-related workflows: fine-tuning (as applicable), prompt and retrieval strategies, evaluations, hallucination checks, guardrails.
• Ranking and personalization: learning-to-rank, recommender patterns, propensity models (bonus).
• Experimentation: strong statistical thinking, causal intuition, offline-to-online translation, metric design.
• Data fluency: SQL and Python, feature engineering, data quality checks, pipeline sanity.
• Bonus: RL or bandits (explore-exploit), multi-agent evaluation or orchestration metrics.

Qualifications and Experience

• 2–6 years building and training ML models that made it to production and moved a business metric.
• Strong fundamentals in ML, math, and statistics; you can reason about trade-offs, not just copy architectures.
• Comfortable with ambiguity, fast iteration, and high ownership.

What’s on offer

• High-ownership role building a core “brain” for the platform.
• Work with strong Product and Engineering teams, a fast shipping culture, and real-world scale.
• In-office first team environment in Gurgaon.
