Senior Machine Learning Engineer

Role Description

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

Qualifications

• 8+ 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.

Requirements

• 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.

Benefits

• Health coverage.
• Paid parental leave.
• Generous paid time-off and holidays.
• Quarterly self-care days off.
• Stock options.
• Support for equipment and connectivity needs.
• Access to LinkedIn Learning platform for learning and development.
• Quarterly wellness education sessions.
• Celebration of employee backgrounds through ERG-hosted events.
