Senior Software Engineer - Roku

Senior Software Engineer - Roku

Location: On-Site - New York / Los Angeles / San Francisco / Ft. Lauderdale

About The Role

You'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 Do

• Design, 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 requirements

• Use RSG 1.3 data transfer APIs, BrightScript Memory Monitor, and Perfetto tracing to find and fix performance problems before users hit them

• Build real-time personalization and engagement features — personalized recommendations, dynamic artwork, ad engagement — within Roku's memory and performance budgets

• Write clear documentation for components, architecture decisions, and platform-specific patterns

• Measure and improve application performance and stability through instrumentation and observability

• Work across agile teams and coordinate with backend engineering and DevOps/SRE on service builds and deploys

• Review code, pair with teammates, and raise the quality bar across the team

• Maintain and improve CI/CD pipelines and testing infrastructure

• Design and run A/B tests, then act on what the data says

• Use AI development tools to move faster and share what works with the team

Required Qualifications

• 6+ years writing software

• 3+ years building Roku applications

• BS in Computer Science, a related field, or equivalent work experience

• You know OOP, data structures, and algorithms well enough to design systems, not just pass interviews

• BrightScript and SceneGraph SDK, including RSG 1.3

• You can explain Roku's memory model, the render-thread/task-thread split, device tiers, and what certification requires

• RESTful API design and data serialization

• Roku frameworks and services: RAF, RMF, RokuPay

• Unit and integration testing on Roku

• protocol and caching behavior

• Git and GitHub

• You write and speak about technical decisions in a way that helps people act on them

• You use AI tools (Copilot, Claude, Cursor, or similar) to write and ship code faster

Desired Qualifications

• BrighterScript and Roku community tooling (ropm, bslint, roku-debug)

• Other OTT platforms: Fire TV, Android TV, Apple TV, Samsung TV, LG webOS

• Observability tools: Conviva, New Relic, Datadog, Sentry

• Microservices and backend-for-frontend patterns

• You've worked with personalization or recommendation APIs on resource-constrained devices

• E2E testing for connected-device applications

• Docker and CI/CD tooling (Jenkins or similar)

• GraphQL

• You share AI tools and workflows that save the team time

• You care about UX enough to push back on Product and Design when something isn't right

• You say "I don't know" when you don't know

• You've worked across time zones without waiting for meetings to unblock you

What Good Looks Like

• You open a 200-file BrightScript repo you've never seen and start making changes the same day

• Other engineers read your code and understand it without a walkthrough

• You notice a memory spike on a Roku Express before QA files a ticket. You fix it and write up what happened

• You track Roku OS releases and adopt new APIs when they solve a real problem, not because they're new

• You write architecture docs, component guides, and Slack explanations that save ten people from asking the same question

• You push back when a plan has gaps. You suggest a better one

• You treat the build pipeline, test coverage, and error monitoring like product features

• You make the people around you better at their jobs
