Senior Software Engineer, Edge AI in Cambridge

Teamwork makes the stream work. 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. 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 will make a valuable - and valued - contribution. We are 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 Team: The Advanced Development team pushes the boundaries beyond product lines to build genuinely new things. We think independently of standard shipping cadences and timelines, working on foundational technologies that could impact every Roku device in the future and on ideas that no one has seen in their living room. Because this is an exceptional team, we are seeking remarkable talent. Everyone here is an expert, but without the myopia of over-specialisation. They have the technical expertise to let them see the bigger picture, but can still go deep into the minutia, pushing back against convention and building something singular and new. They foster a strong sense of collaboration and trust with little room for drama. Together, this is a team of people who love to make decisions and own those decisions.

About the Role: We are looking for a Senior Software Engineer to join our Advanced Development group in Cambridge. You will work on Edge AI — deploying, optimising, and scaling intelligent models directly on-device. These are models that run locally on constrained environments, enabling faster, smarter, and more private user experiences. This is a hands-on, high-impact role for someone who thrives in an environment where innovation meets engineering excellence. You will collaborate with a world-class team of software and hardware engineers, contributing across the entire lifecycle of building, optimising, and delivering next-generation intelligent systems.

What You Will Be Doing: As a Senior Software Engineer, you are willing to contribute wherever needed to get our products out the door. Any company growing at scale thrives on its ability to continuously innovate on new products and features. You will be hands-on and responsible for developing and deploying embedded software for constrained device environments balancing performance, latency, and resource usage. In this role, you will often integrate and optimise AI workloads for both on-device and hybrid (device + cloud) deployments. You will contribute across design, implementation, testing, release, and maintenance — everything else involved in our end-to-end product development and release cycles.

We Are Excited If You Have:

• Hands-on relevant software development experience
• Excellent C and modern C++ coding skills
• Experience developing/debugging on Linux based embedded platforms
• Proven track record of success with embedded system development projects
• Ability to accurately estimate software tasks and work to schedule
• Bachelors/Masters in Computer Science/Computer Engineering/Electrical Engineering or equivalent
• Experience with inferencing machine learning models

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 is 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 are independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust. In short, at Roku you will be part of a company that is 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.
