Mobile Engineer
As a Mobile Engineer at Fireblocks, you will design and implement high-quality native mobile SDKs that enable developers to integrate embedded wallet functionality into their applications. This role is critical to advancing Fireblocks’ mission of providing secure, developer-friendly wallet infrastructure that powers financial applications for leading fintech and crypto companies worldwide.
In this position, you will own SDK features end-to-end—from API design and architecture through implementation, testing, release, versioning, and documentation. You will build secure SDK components for wallet operations, create sample applications and demos, write integration guides, collaborate with developer relations to solve customer integration challenges, and establish best practices in testing, observability, releases, and code health while contributing to a culture of ownership and technical excellence.
The ideal candidate has 5+ years of software engineering experience with a deep focus on mobile development and shipping production-grade SDKs. Strong hands-on experience with iOS (Swift) and/or Android (Kotlin) is required, along with 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, as well as working on security-sensitive mobile software, such as key management, secure storage, cryptography, or financial products, is highly desirable.
Fireblocks offers a competitive compensation package, including a salary range of $177,000 to $230,000 annually, along with bonuses and equity grants. The company also provides remote work options, with a preference for candidates in the Americas time zone, and emphasizes a culture of ownership and execution, leading by example through hands-on work, code reviews, documentation, and knowledge sharing.
Joining Fireblocks means becoming part of a passionate group that moves fast, works with the biggest names in payments and fintech, and is defining how the next generation of financial applications are built. The company operates with a strong product mindset and deep focus on security, reliability, scalability, and exceptional developer experience, offering significant growth opportunities for its employees.
