About 6sense
6sense is Intelligence for Agentic GTM. We turn every signal — yours and ours — into intelligence that every team, tool, and AI agent can act on and trust. Every day, the 6sense Signalverse™ captures one trillion signals to power AI that pinpoints who’s ready to buy, how to engage them, and when to act. 6sense was named a Leader in The Forrester Wave™: Revenue Marketing Platforms for B2B, Q1 2026.
The Opportunity
We’re hiring a Senior Machine Learning Engineer to join our AI team, reporting directly to the Head of AI.
Signals tell you what happened. Our job is to explain why — and that is the problem you will work on. You will build the intelligence that turns a trillion daily signals into cited, explainable answers about why an account matters, why now, and who is deciding. Your models power products customers use every day, including RevvyAI, our conversational GTM intelligence product, and reach their stack through our APIs and MCP server.
This is a build-and-ship role, not a research role. You will own problems end to end, work directly with Product and Go-to-Market, and see your work reach customers. You’ll join a team distributed across the US and India, at a company where AI is the product rather than a feature.
What You’ll Do
- Own machine learning problems end to end — from data exploration and modeling through deployment, monitoring, and iteration in production.
- Build NLP, LLM, and agentic systems at enterprise scale, including retrieval-based architectures and multi-agent workflows.
- Develop ranking, recommendation, prediction, and optimization models that are explainable rather than black-box.
- Partner with Product and Go-to-Market to turn ambiguous business problems into shipped capabilities.
- Improve the performance, scalability, and reliability of production ML systems, and help shape AI platform architecture.
