Senior iOS Engineer

Company: Warp Development

Location: Remote

Type: Full-time, Senior Level

Start Date: As soon as possible

About the Role

Warp Development is looking for a Senior iOS Engineer to design, build, and maintain high-quality native iOS applications. You'll take ownership of features end-to-end—from architecture through to release—working across a modern Swift toolchain with a strong emphasis on modular project structure, automated testing, and CI/CD.

This is a senior, hands-on role suited to an engineer who can work independently, make sound architectural decisions, and raise the bar on engineering quality across the team.

Key Responsibilities

• Design, develop, and maintain native iOS applications using Swift, SwiftUI, and UIKit.

• Architect features and modules following MVVM, ensuring clean separation of concerns and testability.

• Structure and manage the Xcode project using Tuist for modular, scalable project generation.

• Write and maintain unit, integration, and UI tests using Swift Testing, XCTest, swift-snapshot-testing, and XCUITest.

• Build and maintain automated build, testing, and release pipelines using Fastlane.

• Manage version control, code review, and collaborative development workflows through GitHub.

• Diagnose and resolve performance, stability, and UI issues across the app.

• Collaborate closely with product, design, and backend teams to ship polished, reliable features.

• Mentor engineers and contribute to iOS engineering standards and best practices.

What We're Looking For

• Hands-on experience with Tuist or similar modular project tooling.

• Strong testing discipline, with experience across unit, snapshot, and UI automation testing.

• Experience building and maintaining CI/CD pipelines, ideally with Fastlane.

• Comfortable working with Git-based workflows and collaborative code review via GitHub.

• Track record of shipping production apps to the App Store.

• Strong communication skills and the ability to work independently in a remote team.

Nice to Have

• Experience in regulated or high-security environments (e.g. banking, fintech, healthcare).

• Exposure to authentication and security flows (MFA, biometrics, OTP).

• Experience mentoring engineers or leading technical initiatives.

• Familiarity with observability and analytics tooling (e.g. Sentry, Firebase).
