Washington, Washington, D.C., United States Turn2Partners Full time $150,000 - $220,000 per year

This Turn2 client, a leading mobile-first health and wellness company, is hiring a Staff iOS Engineer to support the evolution of its core subscription platform. This role is ideal for a senior-level mobile engineer who enjoys working across disciplines, mentoring teammates, and building polished iOS experiences that directly support millions of users on their health journeys.

You'll join a high-visibility, cross-functional team responsible for subscription infrastructure, upsell flows, and premium feature development. This role blends architecture, product thinking, and deep technical execution.

Why This Role Stands Out:

  • Massive user impact: Help build the core app experience used by a global user base.

  • Modern codebase: Work with both Swift and Objective-C as the team continues modernizing its architecture.

  • Cross-functional collaboration: Partner with teams across Android, backend, web, and product.

What You'll Do:

  • Architect and build features across the iOS codebase with a focus on performance and maintainability.

  • Lead technical decisions and mentor other engineers on iOS best practices.

  • Contribute to subscription management infrastructure and user-facing premium feature development.

  • Write clean, testable code and support TDD/BDD practices.

  • Collaborate closely with data, design, product, and engineering teams to shape user experiences.

  • Help evolve architectural patterns and support refactoring efforts across the app.

  • Participate in code reviews, testing strategy, and deployment automation.

What You Bring:

  • 7+ years of professional experience as a software engineer, with a deep focus on iOS development.

  • Proven experience shipping and maintaining high-traffic iOS applications.

  • Mastery of Objective-C and Swift.

  • Expertise with UIKit, Foundation, and the broader iOS SDK.

  • Experience writing unit tests and building testable, modular code.

  • Familiarity with multithreading, concurrency, and performance tuning.

  • Experience with CI/CD pipelines for iOS app deployment.

  • Strong communication skills and a collaborative, mentorship-focused mindset.

Bonus Points For:

  • Experience with mobile payments or subscription infrastructure.

  • Familiarity with App Store Connect and Apple's release tooling.

  • Exposure to collaborative programming styles (e.g., Pair or Mob Programming).

  • Background in migrating legacy codebases from Objective-C to Swift.

  • Broader experience across Android, Web, or Backend applications.
