About the role

  • Dynamic was founded in 2021 with a simple vision: every app and website will have a wallet component.
  • That vision is rapidly becoming reality.
  • Wallets are no longer limited to crypto-native products, they are becoming foundational infrastructure for payroll, remittances, and global payments.

Responsibilities

  • Design and implement high-quality native mobile SDKs that enable developers to integrate embedded wallet functionality into their applications, with a strong focus on API ergonomics, performance, and reliability.
  • Own SDK features end-to-end: from API design and architecture, through implementation and testing, to release, versioning, and developer documentation.
  • Build and maintain secure, reliable SDK components for wallet operations, including cryptographic operations, blockchain interactions, and security-sensitive flows.
  • Define and evolve the SDK architecture to support long-term maintainability, backward compatibility, and adoption across diverse customer applications.
  • Create clear, comprehensive SDK documentation and integration guides.
  • Work with developer relations and support teams to address customer integration challenges.
  • Dynamic builds and maintains developer-first SDKs that enable teams to seamlessly integrate embedded wallet functionality directly into their applications.
  • These embedded wallets allow end users to create, manage, and use wallets without leaving the product experience, making wallets feel like a native part of modern fintech and crypto apps.
  • As part of Fireblocks, the Dynamic team continues to build and scale the infrastructure and developer tooling that has onboarded 50M+ wallets across crypto and fintech applications.
  • Engineers at Dynamic build secure-by-default systems and approach their work with a strong customer focus, balancing technical excellence with real-world user needs.

Requirements

  • Strong hands-on experience with iOS (Swift) and/or Android (Kotlin)
  • experience with React Native or other cross-platform frameworks, and familiarity with all.
  • Experience with blockchain-enabled mobile systems, including wallet flows, signing, and on-chain interactions.
  • Experience with advanced mobile security primitives (secure hardware, MPC, low-level crypto).
  • For employees hired to work from our NYC HQ, Fireblocks is required by law to include a reasonable estimate of the compensation range for this role.
  • This range is specific to New York City, and takes into consideration a wide range of factors that are reviewed when making a hiring decision, such as years of experience, skills, and other business needs.
