About the role

We’re looking for a Senior iOS Engineer to help build Ondo’s mobile experience. You’ll own features from early product discussions through release and improvement, working closely with design, product, and engineers across the stack. Financial software asks a lot of its interface. People need to understand what they own, what an action will do, and whether it succeeded. You’ll bring strong iOS judgment to those moments: making complex flows feel clear while treating security, accessibility, performance, and reliability as core parts of the product.

What you’ll do

• Build and maintain native iOS features in Swift, from architecture and implementation through App Store release.
• Partner with design and product to turn complex financial workflows into clear, responsive mobile experiences.
• Shape how the app handles authentication, account state, transactions, errors, and interrupted flows.
• Work with backend and platform engineers to define reliable app-facing contracts.
• Improve quality through thoughtful testing, observability, code review, and attention to real user behavior.
• Help set technical direction for iOS and mentor other engineers through collaboration and feedback.

What you bring

• A track record of shipping and improving production iOS apps with Swift.
• Strong command of SwiftUI and practical experience with UIKit where it serves the product.
• Sound judgment about app architecture, asynchronous work, state management, networking, and persistence.
• Experience designing for security, privacy, accessibility, and performance.
• The ability to take ownership of an ambiguous problem, make clear tradeoffs, and bring others along.
• Care for the details users notice and the failure cases they should never have to think about.

Nice to have

• Experience with financial products, trading, digital assets, or wallets.
• Experience building apps that handle sensitive account or transaction flows.
• Familiarity with release automation, analytics, and crash monitoring.
