Roku is changing how the world watches TV. Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and we have set our sights on powering every television in the world. Our mission is to be the TV streaming platform that connects the entire TV ecosystem. We connect consumers to the content they love, enable content publishers to build and monetize large audiences, and provide advertisers unique capabilities to engage consumers.

As a Senior Software Engineer, iOS on the Roku Smart Home team, you will help shape the future of how millions of users interact with their smart devices. You’ll work on building intuitive, reliable, and highly performant iOS experiences that allow customers to monitor and control Roku smart devices—from cameras and lights to sensors and beyond.

This role offers the opportunity to work across a modern, evolving tech stack including Swift, SwiftUI, and Apple’s latest frameworks. You’ll collaborate closely with design, product, and cross-functional engineering teams to bring innovative features to life, improve performance, and make every day smart home interactions seamless.

You should be motivated by curiosity and initiative—eager to take ownership of features and run with them, while remaining grounded in a team-first, collaborative mindset.

About The Team: You will be joining a talented, high-performance team with a history of delivery. We are looking for someone who can help us keep up this pace and continue delivering high-quality apps as we grow.

What You’ll Be Doing:

• Design and build advanced applications and features for the iOS platform
• Integrate with cloud APIs and local device communication protocols to control smart devices
• Write and maintain tests using XCTest/XCUITest frameworks
• Collaborate with cross-functional teams to define, design, and ship new features for mobile devices, optimizing for touch experiences
• Write well-designed, testable, and efficient code
• Debug, profile, and optimize app performance across a range of iOS devices
• Participate in design and code reviews, helping elevate code quality across the team
• Stay up to date with Apple platform capabilities and propose how we can leverage them
• Contribute to roadmap planning, technical design, and release delivery

We’re Excited If You Have:

• Professional iOS development experience, ideally with Swift and/or SwiftUI
• Strong experience shipping and maintaining production apps in the App Store
• Proficiency in using AI tools (e.g., GitHub Copilot, ChatGPT) and experience with prompt engineering
• Experience working with IoT or networked device interactions is a big plus
• Familiarity with BLE, websockets, or MQTT protocols is a bonus
• Experience collaborating with cross-functional teams in agile environments
• Proficient in the iOS development toolset: Xcode, Instruments, Simulator
• Strong understanding of iOS architecture, UI/UX patterns, and app lifecycle
• Excellent communication and debugging skills
• Bachelor’s or Master’s/PHD in Computer Science or related technical field

Benefits: Roku is committed to offering a diverse range of benefits as part of our compensation package to support our employees and their families. Our comprehensive benefits include global access to mental health and financial wellness support and resources.

Our employees can take time off work for vacation and other personal reasons to balance their evolving work and life needs.

The Roku Culture: Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the company's success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. We’re independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust.
