Mobile Engineer

📋 Description

• • As a Mobile Engineer at Fireblocks Ltd., you will design and implement high-quality native mobile SDKs that enable developers to integrate embedded wallet functionality into their applications, focusing on API ergonomics, performance, and reliability. This role is critical to advancing Fireblocks’ mission of enabling businesses to securely access digital assets through Dynamic, its embedded wallet platform trusted by major financial institutions and Web3 companies.
• • You will own SDK features end-to-end — from API design and architecture through implementation, testing, release, versioning, and developer documentation — while building secure, reliable components for wallet operations, including cryptographic functions, blockchain interactions, and security-sensitive flows. You’ll also create sample applications, demos, and comprehensive documentation, and collaborate with developer relations and support teams to resolve customer integration challenges.
• • You’ll join the Dynamic team, founded in 2021 with the vision that every app and website will have a wallet component. The team powers wallet-based experiences for leading crypto and fintech companies like Kraken, zerohash, and Magic Eden, having onboarded 50M+ wallets across applications. Operating with a strong product mindset, the team emphasizes security, reliability, scalability, and exceptional developer experience, working in a fast-paced, distributed environment with a focus on real-world user needs.
• • In this role, you will deepen your expertise in mobile SDK development, security-sensitive systems, and blockchain-enabled applications. You’ll have the opportunity to shape long-term architectural decisions, establish best practices in testing, observability, and release management, and contribute to a culture of ownership and execution by leading through hands-on work, code reviews, and knowledge sharing — all while working on transformative financial infrastructure used by global institutions.
