Senior Partner Engineer

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'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 team 

The Partner Engineering team’s vision is to establish Roku as the preferred platform of choice for our partners (media companies) to distribute and monetize their content globally. The Partner Engineering team’s mission is to be the technical advocate and point of contact for the Partner’s Engineering organization within Roku to help them deliver the best content viewing experience globally for the Roku user community. On a day-to-day basis, we work with engineers from partners organization to help them develop, test, certify, and launch partners direct-to-consumer (DTC) apps in compliance with the Roku platform distribution agreement. We represent partners’ roadmap and technical needs by working cross-functionally with the assigned Partner Engagement Managers, product and engineering teams within Roku. 

About the role 

Roku's platform is live across the multiple European countries, and our European footprint is growing — through Roku TV licensing partners, through our own streaming hardware, and through the local broadcasters and streaming services that make the platform worth owning in each market. 

You will be the senior engineer for our European partners: the person who makes their apps fast, stable and certifiable on Roku, who represents their technical constraints to our platform and OS teams, and who makes each new market launch a technical success rather than a scramble. 

You will be the engineer for a portfolio of European partners — public service and commercial broadcasters, subscription streaming services and pay-TV operators — working with the Partner Engineering team in San Jose and with the Partner Engagement Manager in London who owns those partners’ relationships. You will debug crashes, memory and launch-time issues, diagnose partner-reported streaming problems, and give your partners hands-on support through Roku certification. 

How you’ll work with the Partner Engagement Manager. The Partner Engagement Manager from Roku owns the partner relationship, the launch plan and timeline, partner priorities, and communication during incidents. You own the technical diagnosis, the integration work, and technical sign-off on certification and launch readiness, working engineer to engineer with the partner’s technical team. When something breaks, the Partner Engagement Manager coordinates the response and keeps the partner informed; you find the root cause and the path to a fix. 

Level: Senior individual contributor, with no direct reports. 

Reports to: Director, Partner Engineering, based in San Jose. 

Location and work arrangement: London, UK, in the office Monday to Thursday, with flexible Fridays. Travel within Europe up to 40% of your time. Regular late-afternoon calls with San Jose, whose working day starts at 4pm UK time. 

On-call: For major partner launches and live events, the Partner Engagement Manager is the on-call escalation point and brings this role in for technical diagnosis, which can mean occasional work outside normal hours. 

Expected impact: European partners’ apps pass certification and launch without technical surprises. Additionally, you’ll own the stability, performance and engagement metrics for your partners' apps, and keep each at or better than its benchmark: Roku's certification thresholds and the best-performing apps on the platform. 

• Stability: crash rate, unexpected app closures and out-of-memory terminations 

• Performance: launch time, video start time, video start and playback failures, and rebuffering 

• Engagement: streaming hours per subscriber 

• App Certification and public release: time from technical onboarding to launch in each new market 

• Incidents: platform-caused incidents affecting your partners' apps, and time to resolve them 

What you'll do 

European market expansion 

• Sign off the technical readiness of each new market launch. The Partner Engagement Manager owns the launch plan and timeline; you work with Channel Publishing and Certification to get global and local broadcasters and streaming services onto the platform ahead of a market opening — scoping integrations, running technical onboarding, and clearing the issues that would otherwise surface on launch day. Then write down what “technically ready” meant for that market, so the next launch is faster and cheaper. 
• Represent regional technical requirements inside Roku engineering. European partners hit constraints that do not exist in North America: built-in broadcast TV tuners on Roku TVs, accessibility obligations, rules on how prominently European content is shown, privacy rules for viewing data, and regional differences in content protection and delivery. You will work out what each means technically, and turn it into concrete platform requirements, feature requests and firmware bugs — and follow them to resolution. You don’t need to be an expert in each regulation but should be capable to work cross-functionally with Roku legal, product, engineering to drive these requests to resolution, 
• Help European partners integrate Roku Pay, working with Roku technical teams: you advise partners on their integration, debug it, and test European purchase flows for multi-currency pricing, VAT and invoicing expectations, strong customer authentication (PSD2/SCA) at purchase and re-authentication, and local payment method coverage. 
• Resolve platform issues on Roku TV and operator devices in Europe. When a TV maker’s or operator’s hardware makes partner apps misbehave, you reproduce the problem, measure which devices and apps it affects, and work it to a fix with Roku engineering teams. 

Core Partner Engineering 

• Diagnose and resolve partner app defects end to end — BrightScript/SceneGraph and TypeScript crashes, memory pressure, launch-time and playback-start regressions, general performance problems, and Roku Search integration issues. When the cause is in the partner’s app, you agree the fix with their engineers, who change their own code; you prototype or suggest the patch where it helps. When it’s in the Roku platform, you file it with a reproducible case and work the fix with the team that owns it. 
• Debug streaming and playback problems across DASH and HLS, from manifest and DRM issues to playback problems on physical hardware. 
• Drive adoption of AI-assisted app development to lower partners' total cost of building on Roku. Help partners' engineers use AI coding assistants with Roku's developer tools to build, debug and certify apps faster, feed what you learn back into those tools, and measure the savings in time to certify and engineering effort per release.
