About the role

We're looking for a Data Scientist to own end-to-end ML models and experimentation across the company. This is a high-ownership, execution-heavy role focused on improving conversions, call success rates, and operational efficiency. You'll own problems end-to-end - from metrics and experiments to production models and product impact.


Responsibilities:

  • Own end-to-end ML systems for an AI-driven outbound call centre.
  • Work on problems directly tied to loan sales, collections, and insurance conversions.
  • Drive experiments → product changes → measurable revenue impact.
  • Build user / lead scoring models to decide who to call, when, and how.
  • Improve conversion rates across outbound funnels (dial → connect → conversation → conversion).
  • Work with rich, messy data: call transcripts, recordings, user metadata, and call-level signals.
  • Extract insights from within-call behaviour (drop-offs, objections, engagement patterns).
  • Design and run A/B experiments on model + product changes.
  • Improve LLM agent performance (response quality, handling objections, conversation flow).
  • Identify failure points (bad targeting, poor timing, weak conversations) and solve them using data + ML.
  • Ship models into production and iterate based on real-world performance.


Requirements:

  • Strong Python + SQL (used daily).
  • Hands-on ML experience (practical projects/internships).
  • Ability to go from raw data → insight → model → deployment.
  • Comfort working with noisy, real-world datasets (text, behavioural data).
  • Understanding of experimentation / A-B testing.
  • Strong problem-solving + ownership mindset.


What Success Looks Like:

  • You improve business metrics (conversion, revenue), not just model accuracy.
  • Your work directly influences who gets called and how conversations are handled.
  • You can break down a funnel and explain where and why it's failing.
  • You independently pick problems and drive them end-to-end.


Tech Stack:

  • Python, ML libraries (sklearn / PyTorch)
  • ClickHouse
  • LLMs (Claude, internal systems)
  • Experimentation-driven environment
