Our Dream Machine app is at the forefront of this vision, bringing powerful AI to millions of users in a delightful mobile experience.
Where You Come In
As an iOS Engineer, you will architect and build the next generation of the Dream Machine app, transforming it into a fast, responsive, and magical creative companion. This is a foundational role with significant ownership. You will work from the ground up, collaborating closely with our product, design, and research teams to reimagine what a generative video product feels like in your pocket. You are driven by a product mindset, and you care deeply about how things feel, not just if they work.
What You'll Do
- Architect from the Ground Up: Lead the design and development of core architectural components for the Dream Machine app, using Swift, SwiftUI, and UIKit.
- Ship Polished Experiences: Collaborate with designers and researchers to translate a powerful product vision into elegant, intuitive, and user-focused mobile experiences.
- Master Media Workflows: Build and optimize features for advanced video workflows, including real-time processing, playback, and editing, leveraging frameworks like AVFoundation.
- Tune for Peak Performance: Dive deep into performance, memory management, and power optimization to ensure a fluid experience, especially when handling complex media and on-device AI.
- Elevate the Team: Mentor other engineers, drive technical strategy, and establish best practices for mobile engineering at Luma.
Who You Are
- 5+ years of experience building and shipping high-quality iOS applications, with strong proficiency in Swift, SwiftUI, and UIKit.
- A proven track record of shipping polished, consumer-facing apps that have scaled to real users.
- Deep understanding of iOS architectural patterns and ability to optimize performance, memory, and power.
- A strong product and design sensibility; you have experience influencing UX decisions and partnering closely with designers to achieve a high bar for quality.
- You are a strong communicator and thrive in a collaborative, fast-paced environment where you can take ownership.
What Sets You Apart (Bonus Points)
- Deep experience with AVFoundation, Metal, or other frameworks for video processing, camera workflows, or real-time media.
- A background in building creative, media-rich, or camera-based applications (e.g., video editors, design tools).
- Familiarity with integrating on-device ML models using CoreML or similar frameworks.
The base pay range for this role is $170,000 – $360,000 per year.
