• Own the development of user-facing blockchain applications with a strong focus on security, usability, and reliability • Design and implement high-quality user interfaces for interacting with blockchain wallets and transaction flows • Integrate frontend applications with security-critical core libraries without re-implementing sensitive logic • Ensure safe handling of user inputs, permissions, error states, and edge cases in blockchain interactions • Collaborate closely with backend, protocol, and security engineers to align UX with system constraints and guarantees • Build and maintain scalable component architectures and frontend state management solutions • Ensure applications meet high standards for performance, accessibility, and cross-platform compatibility • Participate in usability testing and iterate on designs based on user feedback and security considerations

• Launch & upgrade chains: standups, hard-forks, snapshots, pruning, clean rollbacks. • Automate everything: modules, golden images, CI/CD, zero-touch deploys across regions. • Run K8s at scale: safe rollouts, HPA/VS/ingress tuning, capacity & cost plans that hold up. • Own incidents: lead SEV0–2, publish RCAs, and ship the change that prevents a replay. • Build signal, not noise: SLOs/error budgets, useful dashboards, alerts that only page when users hurt. • Code where it counts: write/extend tools (snapshots, replay/load, state sync checks); occasionally patch client bugs that bite production and upstream when it’s worth it.
