Senior Software Engineer - Roku

Senior Software Engineer - RokuLocation: On-Site - New York / Los Angeles / San Francisco / Ft. LauderdaleAbout The RoleYou'll build and ship the Paramount+ Roku application used by millions of viewers. The Roku platform has constraints other platforms don't: tight memory budgets, a single-threaded render loop, device hardware that ranges from flagship to five years old. You'll solve problems inside those constraints. We write software that's simple to read, cheap to maintain, and built to last. You'll own features from design through deployment, work across agile teams, and help other engineers get better at this work.What You'll DoDesign, build, and maintain core Roku framework components and application features for Paramount+Architect around Roku's constraints: memory limits, render-thread/task-thread boundaries, device performance tiers, and certification requirementsUse RSG 1.3 data transfer APIs, BrightScript Memory Monitor, and Perfetto tracing to find and fix performance problems before users hit themBuild real-time personalization and engagement features — personalized recommendations, dynamic artwork, ad engagement — within Roku's memory and performance budgetsWrite clear documentation for components, architecture decisions, and platform-specific patternsMeasure and improve application performance and stability through instrumentation and observabilityWork across agile teams and coordinate with backend engineering and DevOps/SRE on service builds and deploysReview code, pair with teammates, and raise the quality bar across the teamMaintain and improve CI/CD pipelines and testing infrastructureDesign and run A/B tests, then act on what the data saysUse AI development tools to move faster and share what works with the teamRequired Qualifications6+ years writing software3+ years building Roku applicationsBS in Computer Science, a related field, or equivalent work experienceYou know OOP, data structures, and algorithms well enough to design systems, not just pass interviewsBrightScript and SceneGraph SDK, including RSG 1.3You can explain Roku's memory model, the render-thread/task-thread split, device tiers, and what certification requiresRESTful API design and data serializationRoku frameworks and services: RAF, RMF, RokuPayUnit and integration testing on Roku protocol and caching behaviorGit and GitHubYou write and speak about technical decisions in a way that helps people act on themYou use AI tools (Copilot, Claude, Cursor, or similar) to write and ship code fasterDesired QualificationsBrighterScript and Roku community tooling (ropm, bslint, roku-debug)Other OTT platforms: Fire TV, Android TV, Apple TV, Samsung TV, LG webOSObservability tools: Conviva, New Relic, Datadog, SentryMicroservices and backend-for-frontend patternsYou've worked with personalization or recommendation APIs on resource-constrained devicesE2E testing for connected-device applicationsDocker and CI/CD tooling (Jenkins or similar)GraphQLYou share AI tools and workflows that save the team timeYou care about UX enough to push back on Product and Design when something isn't rightYou say "I don't know" when you don't knowYou've worked across time zones without waiting for meetings to unblock youWhat Good Looks LikeYou open a 200-file BrightScript repo you've never seen and start making changes the same dayOther engineers read your code and understand it without a walkthroughYou notice a memory spike on a Roku Express before QA files a ticket. You fix it and write up what happenedYou track Roku OS releases and adopt new APIs when they solve a real problem, not because they're newYou write architecture docs, component guides, and Slack explanations that save ten people from asking the same questionYou push back when a plan has gaps. You suggest a better oneYou treat the build pipeline, test coverage, and error monitoring like product featuresYou make the people around you better at their jobsParamount is an equal opportunity employer committed to a diverse and inclusive workplace.
