About the company

Hi, we're Ondo Finance. Our mission is to provide institutional-grade, blockchain-enabled investment products and services. We have both a technology arm that develops decentralized finance technology, and an asset management arm that creates and manages tokenized funds. We are the global leader in tokenized treasuries, tokenized stocks and ETFs, and are building the future of institutional-grade financial services onchain.

Founded by folks from Goldman Sachs Digital Assets Team, we’re backed by some of the best investors in the world including Founders Fund, Coinbase Ventures, Pantera Capital, Tiger Global, and more. We are currently the leaders in the space in terms of AUM and are well capitalized to continue growing the firm. We're fully remote, with team members across the U.S.

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.

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.

What we offer

Competitive compensation including but not limited to salary, future token rights, and/or equity (according to your preferences) — We are well-funded and believe that great talent deserves great compensation.

Full benefits (medical, vision, and dental) and flexible vacation policy (PTO).

Remote-first team across many countries — You will be an early team member helping shape our vision, culture, and design practices.

A+ colleagues — Our team includes alumni from: Goldman Sachs, Blackrock, Two Sigma, Bridgewater, SpaceX, AWS, Meta, Google, McKinsey, Circle, Uniswap.

Best-in-class investors — We are proud to be backed by leading crypto experts and VCs, including Pantera Capital, Founders Fund and Coinbase Ventures.
