Staff Full-Stack Product Engineer - Gemini

Gemini is a global crypto and Web3 platform founded in 2014 by Cameron and Tyler Winklevoss, delivering secure, reliable crypto products to millions of individuals and institutions across 70+ countries.

As a Staff Product Engineer on the Tooling team, you will set the technical vision and drive the architecture for customer-facing platform tooling across backend microservices, web, and mobile surfaces. Your technical leadership will define the core user journey—from initial onboarding and identity/KYC compliance to customer support workflows and complex multi-system initiatives. Operating as a technical multiplier, you will advance Gemini's AI-assisted development tools and agentic SDLC pipeline—where specialized agents plan, implement, and review code alongside human engineers—while mentoring engineers and guiding architectural decisions across the broader product unit.

Key Responsibilities

• Multi-System Architecture & Leadership: Independently scope, design, and deliver end-to-end architectures for complex, cross-cutting challenges spanning backend microservices, web platforms, and mobile apps.
• Core Platform Tooling: Drive the architectural evolution of internal and external platforms backing user onboarding, identity verification (KYC), regulatory compliance, and customer support.
• Agentic SDLC & AI Innovation: Wield and advance AI coding agents and automated harnesses, setting team-wide standards for offloading toil to automation while holding critical decision gates.
• Cross-Team Technical Governance: Plug into design reviews beyond your immediate team, establish best practices for code health and information security, and guide teams away from architectural pitfalls.
• DevOps & Operational Ownership: Own the long-term operational health, security, disaster recovery, and operational review processes for the platforms within your domain.
• Engineering Culture & Mentorship: Act as a technical multiplier by providing compassionate technical coaching, mentoring senior engineers, participating in hiring, and advocating for long-term technical investments.
