About This Internship

As an iOS Engineering Intern at Speak, you’ll help build and ship features that power a language-learning app used by millions of learners around the world. You’ll work closely with experienced iOS engineers, backend engineers, Product, and Design to improve the core mobile experience across learning, monetization, and global expansion.

This is a hands-on, high-impact internship where your work will ship to production. You’ll gain real-world experience building a consumer mobile product at scale while learning best practices in iOS development, experimentation, and product thinking.

What You’ll Be Doing

• Building and shipping iOS features: Contribute to product features that improve the learning experience for millions of users.
• Improving the freemium experience: Help implement and test paywalls, pricing experiments, and monetization flows.
• Supporting global expansion: Assist with launching new markets and languages on iOS.
• Working on core platform systems: Contribute to areas like audio/video playback, speech-to-text experiences, or app performance.
• Collaborating cross-functionally: Partner closely with iOS engineers, backend engineers, Product, and Design to take features from idea to launch.
• Learning at scale: Gain exposure to A/B testing, experimentation frameworks, and production systems used by large consumer apps.

What We’re Looking For

• Pursuing a degree in Computer Science, Engineering, or a related field.
• Experience building iOS applications using Swift (through internships, coursework, or personal projects).
• Familiarity with common iOS architectures (e.g. MVC, MVVM).
• Strong fundamentals in software engineering and a desire to write clean, maintainable code.
• Curiosity about mobile product development and how technical decisions impact users.
• Ability to learn quickly, take feedback well, and thrive in a fast-paced environment.

Nice to have (but not required):

• Experience with SwiftUI
• Exposure to mobile experimentation, analytics, or A/B testing
• Familiarity with media, streaming, or speech-related features

What You’ll Gain

• Real product impact: Your work will ship to production and reach millions of learners worldwide.
• Mentorship: Learn directly from experienced iOS engineers who will support your growth and development.
• Hands-on mobile experience: Build consumer-facing features using modern iOS tools and practices.
• Strong product intuition: Develop a product mindset by working closely with Product and Design.
• A high bar: You’ll be challenged, trusted, and supported to do meaningful work.
