Senior/Staff iOS Engineer (iOS Lead) - Ethena Pay

The lead iOS Engineer is a strong IC who is also the technical authority and primary shipper for our Ethena Pay app, the primary

way users spend, send and grow their money. You’ll own the app end-to-end: building, signing, and releasing it at a quality bar

fit for a money app, in both engineering rigor and visual craft. In a consumer money app, polish is trust, so the app needs to

feel fast, fluid, and pixel-perfect, using modern iOS design (Liquid Glass, SF Symbols, Dynamic Type).

Every iOS question routes through you. You’ll own the passkey/WebAuthn auth surface and the App Store release pipeline, and set

the direction the rest of mobile grows in. This is a hands-on role with real decision authority: the app ships on your word, and

you set the bar for how it’s built.

• Be the top contributor. Write and ship the majority of the Ethena Pay app yourself — the hardest surfaces, the critical path,

the polish — as the most productive hands-on developer on the team, not a lead who reviews from the sidelines.

• Coordinate the App Store release pipeline: certificates, provisioning profiles, entitlements, associated domains, and

TestFlight/App Store submission.

• Raise the iOS quality and visual-craft bar, enforce a test strategy in review, and close UI/polish gaps against the Liquid

Glass design language.

• Act as the default reviewer and decision-maker on iOS, mentoring the team and setting the technical standard others build

against.

• Set mobile direction and drive the roadmap, laying the foundation a phase-2 Android hire and future iOS engineers will build

on.

• Shipped and maintained native iOS apps handling real money or sensitive financial/crypto data, from a world-class consumer app

where design is a competitive advantage (Revolut, Monzo, Cash App, Robinhood, Coinbase, or a design-led crypto app).

• Strong Swift + SwiftUI — modern concurrency (async / await, actors), state and navigation architecture, performance, and

memory; you ship polished, reliable UI.

• A track record of visually excellent, pixel-perfect apps — you can point to shipped apps (App Store links / portfolio) that

look and feel great, are faithful to design down to the detail, and use motion and haptics well. You work hand-in-hand with

designers (Figma) and hold the line on craft. Hands-on with the modern iOS design language, including Liquid Glass (iOS 26)

• You've integrated the classes of SDK a money app relies on — several of: passkeys / WebAuthn (ASAuthorization), embedded-wallet

/ auth infra (Privy, or Dynamic / Turnkey / Magic), WalletConnect / Reown, a KYC SDK (SumSub, Onfido, Persona), account funding

/ aggregation (Mesh, or Plaid-class), and push / attribution (Firebase, AppsFlyer).

• You're agent-native. You wield agentic development — coding agents (e.g. Claude Code), MCP servers, reusable skills — as a

force multiplier, and can explain where it does and doesn't apply on iOS work. Fluent, not a dabbler; you verify output.
