Job description

Our People:

People are the heart and soul of 6sense. We serve with passion and purpose. We live by our Being 6sense values of Win as One Team, Stay Curious, Do The Right Thing, Own the Outcome, and Create Belonging. Every 6sensor plays a part in defining the future of our industry-leading technology. 6sense is a place where difference-makers roll up their sleeves, take risks, act with integrity, and measure success by the value we create for our customers. We want 6sense to be the best chapter of your career.

About the Role :

We’re hiring a Sr. Machine Learning Engineer to join our AI team. 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 withProduct and Go-to-Market, and see your work reach customers. You’ll join a team distributed across theUS and India, at a company where AI is the product rather than a feature

What will you own: :

• 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 thanblack-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 platformarchitecture.
• Explain your work clearly to technical and non-technical audiences, and engage with customers whenneeded.
• Mentor engineers and raise the bar for engineering excellence

What We’re Looking For :

• 6+ years of industry experience building and deploying machine learning systems in production, with clear end-to-end ownership.
• Strong foundation in machine learning and applied statistics, with hands-on depth in NLP, transformers, embeddings, and retrieval-based systems.
• Practical experience with modern GenAI tooling such as LangGraph, LangChain, or Amazon Bedrock.
• Strong Python skills and experience building distributed ML pipelines on cloud infrastructure (AWS, Databricks, or equivalent).
• Solid grasp of feature engineering, model evaluation, and MLOps practices.
• A product mindset — you want to build AI products customers use, and you measure yourself on customer impact.
• Excellent communication: you can explain complex technical work clearly, tell the story of what you’ve built and why, and hold your own with product and business partners.
• Comfort with ambiguity and the judgment to drive execution independently.

Nice to Have :

• Experience with RAG architectures, vector databases, and prompt engineering.
• Hands-on work with PyTorch or TensorFlow.
• Background in B2B SaaS, enterprise AI products, or forward-deployed engineering — especially where you worked directly with complex customer data and delivered quickly.

• Full-time employees can take advantage of health coverage
• paid parental leave
• generous paid time-off and holidays
• quarterly self-care days off
• stock options

We’ll make sure you have the equipment and support you need to work and connect with your teams, at home or in one of our offices.

We have a growth mindset culture that is represented in all that we do, from onboarding through to numerous learning and development initiatives including access to our LinkedIn Learning platform. Employee well-being is also top of mind for us. We host quarterly wellness education sessions to encourage self care and personal growth. From wellness days to ERG-hosted events, we celebrate and energize all 6sense employees and their backgrounds.
