Phantom is revolutionizing the way millions of people interact with the crypto ecosystem. Our self-custodial wallet offers a seamless, unified experience for managing accounts and tokens across Solana, Bitcoin, Ethereum, and Polygon, empowering users with a single, convenient solution. By integrating cutting-edge security features and launching innovative tools for an enhanced personalized user experience, Phantom is able to provide a next-generation, safe and easy-to-use self-custodial wallet for everyone. This strategy has allowed Phantom to achieve significant milestones including surpassing 16 million MAU’s, reaching #1 in the Google play store finance category, and consistently trending as a Top 50 app across all categories, right next to X, PayPal, Coinbase, and ChatGPT.
As a key member of our Growth & Engagement squad, you will own the design, implementation, and optimization of user-facing growth features action cards, referral flows, push-notification experiences, Phantom Pro upsells, and onboarding enhancements. You’ll partner with Product, Design, and Backend to turn hypotheses into polished, performant, and A/B-test-ready interfaces, build reusable component libraries, and instrument every feature for real-time analytics and rapid iteration.
Feature Development: Ship 2+ end-to-end growth UI features per quarter, each with comprehensive E2E tests, documentation, and performance budgets.
Experimentation Enablement: Integrate feature-flags and build rollout controls so PMs can launch, measure, and rollback UI experiments without developer intervention.
Component Library & Design System: Create and maintain reusable, theme-able React (and React Native) components that power all growth experiments and ensure visual consistency.
Instrumentation & Analytics: Emit structured events (clicks, impressions, variant cohorts) for every feature; collaborate with Data to validate pipelines and dashboards.
Performance & Reliability: Optimize first-paint times (<100 ms) and maintain ≤1 % production error rates; participate in front-end on-call rotation and triage issues within 15 minutes.
Cross-Functional Collaboration: Work closely with Backend, Product, Design, and Data teams to unblock dependencies, align on API contracts, and champion a data-driven development process.
Mentorship & Best Practices: Lead code reviews, pair-programming sessions, and knowledge-sharing Dojos to elevate front-end excellence across the team.
7+ Years of Frontend Experience:
building production React applications (web and/or React Native) in high-velocity environments (fintech, consumer apps, SaaS).
Proven track record shipping A/B-tested, feature-flagged interfaces and rapidly iterating based on metrics.
Advanced React and React Native proficiency, including hooks, context, and performance optimization techniques.
Hands-on experience with feature-flag platforms or custom A/B frameworks.
Strong background in TypeScript, component-driven development, and design-system architecture.
Expertise in front-end performance tuning: code-splitting, lazy loading, memoization, and build-time optimizations.
Instrumentation and observability skills: integrating with Segment, Mixpanel, Amplitude, or similar for real-time analytics.
Proficiency with testing frameworks (Jest, Cypress, React Testing Library) and CI/CD pipelines for front-end delivery.
Data-driven mindset: formulates clear UI hypotheses, measures impact, and iterates quickly.
Excellent communicator and collaborator: thrives in cross-functional teams and handles shifting priorities with grace.
Strong ownership and bias for action: comfortable shipping code, monitoring its impact, and refining based on data.
Mentorship orientation: eager to coach IC3-level peers through design reviews and pair-programming.
Prior experience in crypto wallets, payments, or referral/incentive programs.
Contributions to open-source front-end libraries or published talks on growth engineering.
Familiarity with mobile push-notification SDKs and deep-link handling.
We are a team of experienced builders in the blockchain and crypto industry. Our journey began from users seeking an easy, seamless path to accessing the crypto ecosystem. This passion fueled our exponential growth, allowing us to onboard over 16M+ active users in just over three years; with our user base growing weekly. Our dedication to a secure and seamless user experience has made us the leading wallet on Solana as well as our multi-chain approach enhances our platform's versatility, meeting the needs of a diverse and growing user base. By staying at the forefront of technology and user expectations, we continue to innovate and set industry standards on self-custodial crypto wallets.
There has never been a better time to work in crypto to help shape the future of innovation with a focus around the wallet experience!
First impressions matter: Wallets are responsible for a users first impression with crypto and onboarding new users into crypto. By ensuring that a user has a great first-time experience with crypto, we can help supercharge the growth of the entire ecosystem.
Make crypto easier to navigate: There is no easy way for a user to discover and navigate all that crypto has to offer. Wallets have a unique opportunity to help users not only onboard to crypto but also stay retained by exploring new things to do.
We live in a multi-chain world: We currently support Solana, Ethereum, Polygon and Bitcoin with more networks to come in the new future. We are focused on creating a unified, multi-chain crypto experience for users.
