Principal Software Engineer - Product & Onboarding

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 Principal Product Engineer on the Tooling team, you will set the multi-year technical vision and overarching architecture for customer-facing platform tooling across backend microservices, web, and mobile surfaces. Accountable for company-level initiatives, you will solve the hardest technical challenges across organizational boundaries—defining the core systems behind user onboarding, identity verification (KYC/compliance), and customer support. Operating at the highest level of technical leverage, you will shape Gemini's AI-assisted development practice and agentic SDLC pipeline—where specialized agents plan, implement, and review code alongside human engineers—while growing engineering leaders and setting standards across the enterprise.

Key Responsibilities

• Company-Level Architectural Vision: Define and own the multi-year technical vision, reliability standards, and system architecture for Gemini's customer-facing platform.
• Cross-Organizational Technical Governance: Review critical designs across the company, drive architecture for the most complex technical challenges, and set operational guidelines across engineering verticals.
• Core Initiative Accountability: Take full accountability for company-critical programs spanning onboarding, compliance (KYC/identity), and support infrastructure from ambiguity through long-term operation.
• Agentic SDLC & Frontier AI Tooling: Shape the evolution of Gemini's agentic development pipeline, establishing operational patterns, human-in-the-loop gates, and AI-assisted engineering practices for the broader organization.
• System Defense & Incident Leadership: Proactively raise security, reliability, and code quality standards across teams while debugging and contributing to mission-critical codepaths when required.
• Technical Multiplier & Talent Development: Mentor and develop senior engineers and future engineering leaders, delegate strategic initiatives, drive bar-raising in hiring, and foster a healthy engineering culture.
