Roku is changing how the world watches TV

Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and we've set our sights on powering every television in the world. Roku pioneered streaming to the TV. 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.

From your first day at Roku, you'll make a valuable - and valued - contribution. We're a fast-growing public company where no one is a bystander. We offer you the opportunity to delight millions of TV streamers around the world while gaining meaningful experience across a variety of disciplines.

About The Role

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 app as we grow.

With so many people using our products globally, we’ve become well-known for products that “just work” right out of the box and integrate almost by magic. That doesn’t happen by accident, which is why we are committed to making sure our products aren’t just intuitive, they’re obvious.

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, webs sockets, 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. Local benefits include statutory and voluntary benefits which may include healthcare (medical, dental, and vision), life, accident, disability, commuter, and retirement options (401(k)/pension). Our employees can take time off work for vacation and other personal reasons to balance their evolving work and life needs. It's important to note that not every benefit is available in all locations or for every role. For details specific to your location, please consult with your recruiter.

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. In short, at Roku you'll be part of a company that's changing how the world watches TV. 

We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two-part idea. We come up with the solution, but the solution isn't real until it is built and delivered to the customer. That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
