Job Description
<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: Platform Security</strong></span></p>
<p>The Platform Security team secures Gemini’s infrastructure through service hardening and by developing and supporting a suite of foundational tools. We provide secure-by-default infrastructure, consumable security services, and expert consultation to engineering teams for secure cloud and non-cloud infrastructure.</p>
<p><span style="font-weight: 400;"><strong>The Role: Staff Platform Security Engineer</strong></span></p>
<p>The Platform Security team builds and delivers zero-trust foundations and paved paths so every Gemini team can ship safely on supported cloud platforms. As a Staff Security Engineer, you will build security services, tools, and automation while hardening our cloud environments (primarily AWS), securing container orchestration platforms, and implementing infrastructure-as-code security guardrails. This is a hands-on engineering role where you'll write production code daily, not just infrastructure-as-code.</p>
<p>You'll design and build security platforms that scale across our engineering organization. This role requires deep technical expertise in cloud security, strong Terraform proficiency, and strong software development skills to build production services. You will partner closely with engineering teams to enable rapid, secure delivery while maintaining zero standing privilege and least-privilege access models.</p>
<p><span style="font-weight: 400;"><strong>Responsibilities:</strong></span></p>

<li>Build and maintain security services, tools, and automation using Python or Go</li>
<li>Design and implement security controls for AWS and Kubernetes environments using infrastructure-as-code</li>
<li>Create reusable libraries, frameworks, and platforms that enable secure-by-default patterns</li>
<li>Develop automated security monitoring, scanning, and remediation services</li>
