Description

As the Head of AI & Machine Learning, you will lead the development of transformative AI systems, leveraging generative AI and multi-agent architectures to deliver innovative solutions. Your work will focus on creating advanced, custom AI models that process complex, multi-modal data and provide actionable insights. Internally, you will enhance operational efficiency through AI-driven systems. Externally, you will redefine user experiences by delivering personalized, transparent, and accessible AI solutions.

Responsibilities

  • Lead the development and scaling of a multi-agent AI platform to deliver sophisticated, end-to-end solutions.

  • Enhance integration with foundation models while building custom AI capabilities tailored to specific needs.

  • Design and expand agent workflows to handle complex tasks and decision-making processes.

  • Develop specialized neural architectures optimized for domain-specific reasoning and decision-making.

  • Create purpose-built AI agents with capabilities beyond general-purpose models.

  • Engineer proprietary orchestration layers to enable seamless collaboration among AI agents.

  • Build advanced systems to extract insights from diverse data sources, including documents, market signals, and user inputs.

  • Design novel evaluation frameworks to measure performance, trust, and qualitative outcomes.

  • Implement intelligence loops to enable continuous knowledge accumulation from user interactions.

  • Create explainable AI decision pathways to ensure transparency for users and compliance with regulations.

  • Architect adaptive interfaces that evolve based on user behavior and preferences.

  • Design privacy-preserving AI systems to protect sensitive data while enabling personalization.

  • Implement regulatory compliance guardrails to ensure adherence to industry standards.

  • Collaborate with leadership, engineering, operations, and design teams to integrate AI systems into products.

  • Stay at the forefront of AI innovation, researching and applying breakthrough techniques.

About this role

Pivotal Solutions is seeking a Head of AI & Machine Learning to lead the design and deployment of sophisticated multi-agent AI systems in San Francisco. This role combines research-level technical depth with product leadership, requiring you to architect custom AI models that handle complex, multi-modal data while balancing innovation with transparency and regulatory compliance. You'll own the full stack—from building specialized neural architectures and orchestration layers to designing explainable decision pathways and privacy-preserving systems—while collaborating across engineering, operations, and design to embed these capabilities into both internal operations and customer-facing products.

The ideal candidate holds a PhD in Computer Science, Machine Learning, or AI, with 5+ years of hands-on R&D experience at leading AI labs or tech companies. You should have deep expertise in large language models, multi-agent systems, and orchestration, with proven success building practical agent-based systems for high-stakes domains like finance or regulated industries. Beyond technical chops in Python, TensorFlow, PyTorch, and retrieval-augmented generation, you'll need demonstrated strength in explainable AI, human-AI interaction design, and privacy-preserving techniques—plus the leadership ability to mentor teams and translate business requirements into robust architectures.

This is an in-office, full-time position suited for someone who wants to shape how AI systems are built for real-world impact, with particular appeal to researchers or senior practitioners ready to move from labs into a leadership role that spans both innovation and responsible deployment.
