Senior Product Engineer - Tooling & AI Platform

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 Senior Product Engineer on the Tooling team, you will build and scale customer-facing platform tooling across backend, web, and mobile surfaces. Your work will shape the core user journey—from initial user onboarding and identity/KYC compliance to customer support workflows and ad-hoc platform features. Operating in a high-ownership environment, you will leverage AI-assisted development tools and an agentic SDLC pipeline where specialized agents plan, implement, and review code alongside human engineers.

• Core Platform Tooling: Architect and maintain internal and external workflows backing user onboarding, identity verification (KYC), regulatory compliance, and customer support.
• Agentic SDLC & AI Automation: Utilize AI coding agents and automated harnesses in daily workflows to eliminate toil and refine Gemini’s continuous delivery pipeline.
• DevOps Lifecycle Ownership: Build, validate, deploy, monitor, and maintain production services throughout their operational lifespan.
• System Architecture & Trade-Offs: Provide technical input during product scoping, making well-reasoned trade-offs between delivery speed and system quality.
• Code Governance & Mentorship: Conduct thorough code reviews for information security, correctness, and style while mentoring junior/mid-level engineers.
