Mission

Speechify is the easiest way to listen to the world’s information. Articles on the web, documents in the cloud, books on your phone. We absorb it all and let you listen to it at your desk, on the go, at your own speed, and with tools that make learning easier, deeper, and faster.

What streaming services have done for audio entertainment, we’re doing for audio information. And whatever we’re doing seems to be working. We’re #1 in our category, and experiencing exponential growth.

Together, Fireblocks and Dynamic are building the most complete, secure, and developer-friendly wallet infrastructure in the industry by combining institutional-grade security with consumer-grade experiences.

About the Team

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. Dynamic powers wallet-based experiences for leading crypto and fintech teams including Kraken, zerohash, Magic Eden, and more.

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. In this context, Dynamic powers the application-layer wallet experience and developer tooling, complementing Fireblocks’ core custody, security, and transaction infrastructure.

What You’ll Do

• 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.
• Build sample applications and demos that showcase SDK capabilities and serve as integration references for customers.
• Create clear, comprehensive SDK documentation and integration guides.
• Work with developer relations and support teams to address customer integration challenges.
• Raise the bar for quality and operational excellence by establishing best practices around testing, observability, releases, and code health.
• Contribute to a culture of ownership and execution, leading by example through hands-on work, code reviews, documentation, and knowledge sharing

What You’ll Bring

• 5+ years of software engineering experience, with deep focus on mobile development and shipping production-grade SDKs
• Demonstrated track record of building and shipping high-quality code, with work you can point to and discuss in depth
• 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 building mobile SDKs or shared libraries, including API design, versioning, packaging, and long-term maintenance across platforms.
• Experience with blockchain-enabled mobile systems, including wallet flows, signing, and on-chain interactions.
• Experience working on security-sensitive mobile software, such as key management, secure storage, cryptography, or financial products.
• Strong grasp of mobile engineering best practices, including CI/CD, automated testing, release management, and observability.
• A get-things-done mindset with the ability to independently own problems and deliver end-to-end solutions.
• Comfortable making long-term architectural decisions while remaining pragmatic and adaptable.
• B.Sc. in Computer Science / Engineering or equivalent practical experience.
• Remote role in a distributed team; preference for candidates in the Americas time zone

Big Advantages

• Rust and/or WebAssembly (Wasm) experience, particularly building cross-platform SDKs consumed by mobile apps.
