Lead iOS Engineer (Swift/SwiftUI) - Portugal Full Remote

ABOUT THE OPPORTUNITY Join a fast-growing EdTech startup helping more than 1. 5 million students worldwide study better and stay motivated through an AI-powered learning platform.

With tens of thousands of new students joining each week and approximately $4 million in seed funding, the company is expanding its mobile capabilities.

You will work directly with the founders, influence product decisions and help shape how students engage with learning every day. The role is fully remote within Europe. Being based in Portugal, particularly Lisbon, is preferred but not required.

PROJECT & CONTEXT Own the mobile app end-to-end across architecture, performance, release processes and technical roadmap. Set technical direction and mentor the two engineers already supporting mobile, raising engineering standards while maintaining a pragmatic approach to delivery.

Partner with engineering and product leadership on onboarding, growth and retention. Deliver a polished native experience through smooth animations, responsive interactions and platform-specific conventions.

Work in a product-led growth environment: ship features, instrument user journeys, run A/B tests, measure impact and iterate quickly. Manage App Store releases, versioning, store optimization, crash monitoring and performance improvements. As mobile grows, you may also help build a dedicated mobile team.

The core iOS technologies include Swift, SwiftUI, UIKit and Combine. The wider platform uses Node. js, React, React Native, Next. js, NestJS, Expo, Prisma, Tailwind CSS and AWS. Specific technology versions and supported iOS versions are to be confirmed.
