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: Predictions The Role: Senior Software Engineer (Mobile) As a Senior Mobile Engineer on the Predictions team, you'll own the mobile experience for Gemini's CFTC-regulated prediction markets exchange. You'll build and ship trading interfaces for event contracts — from order entry and position management to real-time market data — within Gemini's React Native app. You'll work closely with product, design, backend, and compliance to bring new contract types (binary, range, combo) to market on mobile and drive activation and retention for a fast-growing product line. Responsibilities: Build and maintain the Predictions mobile trading experience end-to-end: market browsing, order placement, portfolio views, and settlement flows. Architect performant, real-time UI for streaming market data (orderbook, price charts, position P&L) using modern React Native patterns (TurboModules, JSI, native navigator integration). Collaborate with backend engineers on gRPC and WebSocket integrations that power live trading surfaces. Create reusable, well-tested UI components shared across Predictions and the broader Gemini mobile app. Partner with product and design to shape mobile-specific UX for new contract categories (weather, economics, crypto, sports) and features like combo contracts and range contracts. Scope and implement solutions independently, making informed architecture decisions and tradeoffs around native vs. JS boundaries. Establish and improve mobile development processes — testing strategy, release quality gates, OTA vs. native release decisions. Conduct thorough code reviews and mentor other engineers on React Native best practices. Use analytics and experimentation data to inform product and engineering decisions around activation funnels, onboarding, and trading engagement. Minimum Qualifications: 6+ years of software engineering experience, including 4+ years building production mobile applications with React Native. Strong proficiency in TypeScript. Deep understanding of React Native internals — bridging, native modules, performance profiling, and debugging. Experience building real-time, data-intensive UIs (trading, dashboards, live feeds). Strong UX/UI sensibility with a track record of contributing to design and product decisions, not just implementing specs. Expertise in unit and integration testing for mobile. Comfort working in a regulated environment where changes require rigor and auditability. Preferred Qualifications: Experience with financial or trading applications (orderbooks, charting, position management). Familiarity with Expo, EAS, and OTA update strategies. Experience with native module authoring (Swift/Kotlin) or SwiftUI/Jetpack Compose embedding via Expo Modules API. Exposure to gRPC, WebSockets, or similar real-time transport protocols. Experience with performance analysis tooling (Flipper, React DevTools profiler, native instruments). Prior work at a fintech, exchange, or other regulated product environment.

The Department: Tooling The Role: Senior Software Engineer (Product) As a Senior Product Engineer on the Tooling team, you'll work across backend, web, and mobile to build the customer-facing platform tooling that shapes how millions of users experience Gemini - onboarding, compliance, customer support, and the ad hoc projects that keep the customer journey smooth from first touch onward. This is a broad, high-ownership role for an engineer who is comfortable moving up and down the stack, picking up whatever a problem requires, and shipping products end to end. You'll join a team that treats AI-assisted development and automation as first-class tools.

Leverage AI coding tools and our agentic development pipeline to move faster, and help improve the automation itself. Own the DevOps lifecycle for the products you build: building, validating, monitoring, and maintaining them over their lifetime. Provide technical input to planning, design, and requirements for new products and features, making well-reasoned tradeoffs between speed and quality. Conduct meaningful code reviews for correctness, style, and information security. Mentor engineers, share best practices, and contribute to the technical direction and engineering culture of the team. Take on ambiguous, cross-cutting problems and drive them to resolution independently. Minimum Qualifications: 4+ years of software engineering experience building and maintaining production systems at scale. Demonstrated ability to work across multiple layers of the stack: backend services plus web and/or mobile - and a willingness to work wherever a problem requires. Proficiency in a typed language (e.g., TypeScript, Scala, Java, Go) and comfort with JavaScript/TypeScript for web and mobile surfaces. Experience building consumer-facing applications, with a strong understanding of UX/UI concepts and product sensibility. Fluency in using AI coding tools and automation as part of your everyday workflow. Expertise in unit and integration testing and a commitment to code health, testing, and maintainability. A customer and product-focused mindset, with the ability to make well-reasoned tradeoffs between speed and quality. The ability to work across teams and time zones, manage dependencies, and handle multiple competing priorities. Excellent communication and teamwork skills. Preferred Qualifications: Experience in the crypto or fintech industry, or as a user of crypto products. Experience with onboarding, identity/KYC, compliance, or customer support tooling. Experience building and operating AI agents or agentic workflows in production. Familiarity with React/React Native and cloud/microservices architecture.
