Senior Platform Engineer

About the Company 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. The Department: Platform Our Platform organization’s purpose is to enable Gemini to scale effectively and empower our engineering teams to focus on building innovative financial products and experiences for individuals around the world. Platform focuses on building a scalable and secure foundations platform, enabling Engineering to develop, deploy, validate, and operate services in production; improve resiliency; increase organizational efficiency by reducing operational toil; and improve system efficiency through architectural evolution. The Platform team builds products for engineers. We work directly with product, data, security, and infrastructure teams to understand their needs, establish safe and opinionated defaults, and provide paved paths that make the reliable choice the easy choice. We treat internal platforms as production software with users, service-level objectives, roadmaps, documentation, and feedback loops, not as collections of configuration. The Role: Senior Platform Engineer You will design, build, and operate the software and infrastructure that form Gemini’s internal engineering platform. This is a software engineering role grounded in deep production and infrastructure experience. You will build self-service systems, developer tools, and automation that improve the way teams create, deploy, scale, observe, and operate services. You will partner with engineering teams to turn broad operational needs into reliable platform products. You will make infrastructure programmable, secure, observable, and resilient; use SLOs and error budgets to guide tradeoffs; and continuously replace manual operational work with well-designed software. The role spans software, systems, and infrastructure engineering, with an emphasis on durable abstractions and measurable improvements to developer velocity and production reliability. The role spans cloud platforms, networking, compute, storage, infrastructure automation, CI/CD, and the systems required to run highly available services in production. Responsibilities: • Design, build, and maintain platform services, APIs, CLIs, controllers, and automation in languages such as Go, Python, or similar; own them through design, implementation, testing, deployment, and production operation. • Build self-service capabilities that let engineers provision environments, deploy services, manage infrastructure, and respond to operational conditions safely without relying on manual platform intervention. • Create and evolve paved paths for service development and delivery, including templates, libraries, deployment workflows, policy-as-code, and reusable platform primitives. • Design and improve the cloud, compute, storage, identity, and infrastructure primitives used by engineering teams. • Design and operate core network infrastructure — VPCs, Cloud Routing, and security controls across public clouds and regions. • Operate and improve the compute, container, networking, and cloud foundations that support critical services and
