Our client is a rapidly growing, venture-backed AI company building secure, enterprise-grade AI solutions for highly regulated industries. Their platform helps organizations unlock the value of complex data by embedding AI into mission-critical workflows, improving decision-making, operational efficiency, and knowledge discovery. As the company continues to scale, they are investing heavily in next-generation AI capabilities, including search, knowledge exploration, semantic reasoning, and agentic AI.

This is an opportunity to join a high-caliber engineering team tackling technically challenging problems at production scale while helping shape the future direction of the platform.

The Role

As a Staff Applied Machine Learning Engineer, you will design, build, and deploy advanced machine learning solutions that power intelligent search, knowledge exploration, and AI-driven workflows. You'll work closely with product, platform, and engineering teams to develop production-grade ML systems, combining strong software engineering fundamentals with expertise in modern AI techniques. This is a highly technical individual contributor role with significant ownership and influence over architectural decisions.

Responsibilities

• Lead the design, development, and deployment of machine learning models for large-scale production systems.
• Design and build intelligent search and knowledge exploration capabilities using modern ML techniques.
• Develop systems involving knowledge graphs, semantic representations, and advanced entity understanding.
• Collaborate with engineering and product teams to deliver end-to-end machine learning solutions.
• Evaluate model performance, runtime efficiency, and scalability in production environments.
• Communicate technical decisions, trade-offs, and recommendations to both technical and non-technical stakeholders.
• Build high-quality enterprise software while maintaining a fast pace of delivery.
• Take ownership of projects from design through implementation, deployment, and ongoing support.
• Troubleshoot and support distributed production systems.
• Stay current with advances in AI and machine learning and apply emerging techniques where appropriate.
