Senior/Staff iOS Engineer (iOS Lead) em Lisboa, Portugal is listed on Jobeax. Browse 30,000+ vacancies available.
Role Overview
The lead iOS Engineer is a strong IC who is also the technical authority and primary shipper for our native app, the primary way users hold and move 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.
Role Responsibilities
Be the top contributor. Write and ship the majority of the 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.
Own the native iOS app end-to-end - architecture, build, and quality bar - across both engineering rigor and visual craft.
Coordinate the App Store release pipeline: certificates, provisioning profiles, entitlements, associated domains, and TestFlight/App Store submission.
Own core app surfaces with full design authority, keeping each legible, documented, and easy for the team to build on.
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.
Required Skills and Experience
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).
Secure on-device handling - Keychain, biometric gating, and disciplined avoidance of token/PII leakage to logs or analytics.
Comfortable owning and evolving a large existing iOS codebase, with the judgment to set technical direction.
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.
