Principal Software Engineer, Tooling (Product)

<p><strong>About the Company</strong></p> <p>Gemini is a global crypto and Web3 platform founded by Cameron and Tyler Winklevoss in 2014, offering a wide range of simple, reliable, and secure crypto products and services to individuals and institutions in over 70 countries. Our mission is to unlock the next era of financial, creative, and personal freedom by providing trusted access to the decentralized future. We envision a world where crypto reshapes the global financial system, internet, and money to create greater choice, independence, and opportunity for all — bridging traditional finance with the emerging cryptoeconomy in a way that is more open, fair, and secure. As a publicly traded company, Gemini is poised to accelerate this vision with greater scale, reach, and impact.</p> <p><span style="font-weight: 400;"><strong>The Department: Tooling</strong></span></p> <p><span style="font-weight: 400;"><strong>The Role:</strong> <strong>Principal Software Engineer (Product)</strong></span></p> <p>As a Principal Product Engineer, you'll set technical direction for the customer-facing platform that defines how millions of users experience Gemini — onboarding, compliance, customer support, and the systems that hold the customer journey together. This is a role for an engineer who operates at the level of the technology itself: someone accountable for company-level initiatives, who drives the hardest technical challenges across organizational boundaries, and who creates the architectural vision that other teams build against.&nbsp;</p> <p>You'll work across backend, web, and mobile, but your leverage comes less from what you build directly than from the direction you set, the leaders you grow, and the frontier you push. We treat AI-assisted development and automation as first-class — an agentic SDLC pipeline where agents plan, implement, and review work through our harness under human gates. As a Principal, you're expected to shape where that frontier goes, define the patterns and operational guidelines other engineers adopt, and advance how the whole organization builds. If you're energized by owning ambiguous, company-critical technical bets and multiplying the engineers around you, we'd love to talk.</p> <p><span style="font-weight: 400;"><em>This role is required to be in person twice a week at our New York City, NY office.</em></span></p> <p><span style="font-weight: 400;"><strong>Responsibilities:</strong></span></p> <ul> <li>Own the technical vision and architecture for the customer-facing platform, designing for scale and reliability with a multi-year horizon and anticipating needs before they arrive.</li> <li>Review critical designs across or
