Product Engineer - Frontend​/Fullstack

Senior Staff Product Engineer — Full Stack / Frontend Focus

Location: East Bay, CA

Work Arrangement: Hybrid

A rapidly evolving technology organization is expanding its engineering team to build sophisticated software products incorporating modern AI capabilities.

We’re looking for a highly experienced Senior Staff Product Engineer with a strong frontend background and the ability to operate across the full application stack.

• Build sophisticated web applications with an emphasis on usability, responsiveness, maintainability, and frontend architecture.
• Develop application services and APIs supporting complex, data-driven product functionality.
• Work closely with product and design partners to turn ambiguous requirements into well-engineered software experiences.
• Incorporate emerging AI capabilities into production applications, including natural-language interfaces, intelligent discovery, recommendations, summarization, and automated workflows.
• Own major initiatives throughout the engineering lifecycle — from technical discovery and architecture through implementation, launch, and continuous improvement.
• Establish scalable frontend patterns, shared components, and engineering practices that improve consistency and development velocity.
• Collaborate with engineers across AI, data, infrastructure, and platform teams to integrate intelligent services into customer-facing applications.
• Identify and resolve architectural and technical challenges affecting application performance, scalability, reliability, and maintainability.
• Provide technical leadership through design discussions, code reviews, mentoring, and hands-on problem solving.
• Help establish longer-term engineering direction while remaining an active individual contributor.

• Significant experience building and scaling sophisticated software products.
• Professional experience developing backend services with Python and modern web frameworks.
• Strong understanding of APIs, distributed application architecture, and full-stack development.
• Experience putting LLM or generative AI capabilities into production software
  .
• Strong frontend architecture experience, including component systems, state management, performance optimization, and application scalability.
• Comfortable working across application, data, and service layers rather than operating exclusively within one technical discipline.
• Experience partnering with Product and Design to deliver polished customer-facing experiences.
• Demonstrated technical leadership at Staff, Senior Staff, Principal, or equivalent level.
• A history of mentoring engineers and influencing engineering practices beyond your immediate area.

This is an opportunity for an engineer who wants significant architectural influence without leaving hands-on development behind
.

You’ll help shape the next generation of an established technology platform, work on meaningful AI-enabled product capabilities, and influence engineering practices as the organization continues to scale.
