• Experience architecting modular, testable, and performant iOS codebases from the ground up.

• A passion for crafting beautiful, fluid, and intuitive UI/UX experiences.

• Solid understanding of data handling, background threading, caching strategies, and persistence (e.g., Core Data, SQLite).

• Experience with instrumentation and tooling for performance analysis, crash reporting, and continuous monitoring.

• Proven ability to ship quickly without sacrificing stability, polish, or scalability.

• Clear communication skills and comfort working closely with designers and cross-functional teams.

• A Bachelor’s degree in Computer Science or equivalent practical experience.

Standout Experience:

• Led architecture or re-architecture of a high-scale, user-facing mobile app.

• Worked in fast-paced, product-driven environments like Stripe, Coinbase, or Robinhood.

• Familiarity with Web3 technologies, Solana wallets, or cryptographic integrations on mobile.

About the role:

As a Senior iOS Engineer, you’ll take ownership of designing and delivering performant, scalable, and sleek mobile features for our Web3-powered tools and apps. You’ll work closely with design and backend teams to build a seamless user experience for developers and end users alike.

Key responsibilities:

• Architect and implement high-quality iOS features with an emphasis on performance and scalability.

• Own mobile performance, from launch time and memory usage to smooth interactions and responsiveness.

• Define and maintain patterns and frameworks to keep the codebase scalable and efficient.

• Integrate with REST/GraphQL APIs and implement robust data handling, including offline support and caching.

• Collaborate with designers to deliver pixel-perfect, platform-native UI.

• Contribute to developer tooling, CI/CD pipelines, testing strategies, and documentation.

• Drive best practices across the engineering team.

What does success in this role look like?

• In three months, you’ve led the implementation of core features, contributed to architectural decisions, and driven improvements in performance and code quality.

• In six months, you’ve led a major performance upgrade or refactor, contributed to product planning, and established iOS best practices.

• In twelve months, you’ve helped define the long-term vision for our mobile platform, led large-scale architecture initiatives, and ensured the app scales with our growing user base.
