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 With more than 100 million 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. Our goal is to help people find what they want and make it easier for people to stream. We do this with state-of-the-art technology and engineering, keeping the customer at the center of everything we do. We're looking for a hands-on, systems-oriented Senior Software Engineer in Test (Sr. SDET) to join our Browse and Discovery Team. You'll own quality for the APIs and data pipelines — the automated test frameworks, containerized quality checks, CI/CD workflows, and infrastructure as code that let the rest of the organization ship with confidence. You'll do that work with agentic AI as your default mode of working: driving agents to write and maintain integration tests, keep suites healthy, triage failures, and debug production issues, and building the tools, harnesses, and evaluations that make those workflows trustworthy. This is a role for someone who treats agent design as an engineering discipline — grounding agents in the right context, integrating them with the systems they act on, proving them reliable through rigorous automation and evaluation, and turning what works into the reusable components and paved paths other teams at Roku build on. For California Only - The estimated annual base salary for this position is between $141,300 - $360,700. Compensation packages are based on factors unique to each candidate, including but not limited to skill set, certifications, and specific geographical location.

What you'll be doing Design and develop automated test frameworks for APIs and data pipelines, and containerize automated quality checks for complex orchestrated services. Use agentic AI workflows day to day — authoring and maintaining integration tests, keeping test suites healthy, triaging failures, and debugging production issues. Build the context and retrieval pipelines that ground these agents in the right code, schemas, telemetry, and business logic, and keep them aligned as those sources evolve. Implement tool-calling and MCP-style integrations so agents can safely act on the systems around them — test runners, CI, ticketing, logs, and data services. Build and maintain CI/CD workflows and infrastructure as code using Terraform or CloudFormation, so deployments and test execution are repeatable and auditable. Establish evaluation, observability, and monitoring for the signals that matter here: test reliability and flake rate, mean time to triage, agent task success rate, latency, and cost. Build safeguards that improve production readiness and reliability — controlled rollouts, drift detection, and mechanisms that prevent error amplification in multi-step agent workflows. Create reusable templates, modular components, and paved-path patterns that accelerate adoption across teams, and partner with development, data engineering, and product teams to improve end-to-end testing and release processes. We're excited if you have 5+ years of experience in software testing and automation, software engineering, or adjacent domains, with strong software engineering fundamentals and the ability to build production-grade systems. Expertise in Python or Java with familiarity in the other; experience with C/C++ or another systems language is a plus. Experience designing test plans, test cases, and automated test frameworks for APIs, services, and data pipelines. Hands-on experience with LLM-based systems, including prompt design, retrieval, tool use, memory handling, and agent orchestration patterns. Experience building and maintaining retrieval and context pipelines, agent frameworks, and MCP servers or equivalent function-calling architectures. Experience with CI/CD tooling such as GitLab runners, GitHub Actions, Jenkins, or Travis CI. Experience with cloud platforms — AWS (preferred), GCP, or Azure — REST APIs, and containerization and orchestration tools such as Docker and Kubernetes. Experience with infrastructure as code: Terraform or CloudFormation. Working knowledge of Linux and Bash scripting. Experience with observability, evaluation, experimentation, and feedback loops for AI systems in production, including monitoring tools such as DataDog, Prometheus, or Grafana. Ability to work independently, manage ambiguity, move quickly, and deliver incrementally in a fast-paced environment. Strong analytical and problem-solving skills, excellent communication and collaboration skills, and sound engineering judgment. Bachelor's or master's degree in Computer Science, Computer Engineering, Electrical Engineering, Data Science, or a related technical field — or equivalent engineering experience. #LI-BD1 What's Roku's approach to hybrid working?

At Roku, we don’t just use AI, we work with it. AI agents and smart tools help power drafts, analysis, and repetitive workflows, while our people bring direction, judgment, and accountability. We’re looking for curious, adaptable builders who can show how they’ve used AI or automation to move faster, raise the bar, and scale their impact. We value your AI skills if you have built fluency across the agentic engineering toolchain — coding harnesses like Claude Code or Cursor, MCP servers, custom skills, or agent frameworks. And you can describe projects where you shipped real work with these tools. You know how to drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you. What You'll Be Doing Design, build, and operate core components of a large-scale, real-time distributed decisioning system with strict latency requirements Take end-to-end ownership of specific subsystems: architecture, implementation, testing, deployment, on-call, and long-term evolution Build a working mental model of a highly distributed, complex production system, and make high-leverage contributions Identify opportunities to continuously evolve the system and tooling Partner with engineers and applied scientists working at the intersection of distributed systems and statistical/ML-driven decision-making Diagnose and resolve subtle, often timing- or statistics-related issues in a highly concurrent, multi-region distributed system Mentor other engineers and raise the bar on engineering rigor, testing discipline, and operational excellence across the team Communicate clearly with both technical and non-technical stakeholders, and drive alignment across engineering, product, and business partners We're Excited If You Have 10+ years of experience designing, building, and operating large-scale, low-latency distributed systems — ideally including at least one system you built substantially from the ground up A demonstrated track record of owning complex systems end-to-end: design, build, operate, on-call, and iterate based on production feedback Proven ability to ramp quickly on unfamiliar, complex, large codebases and become productive fast — you enjoy the “figure it out” part of the job as much as the “build it” part Experience evolving and refactoring live, business-critical systems without compromising uptime or correctness Strong command of Java, with a solid foundation in algorithms, data structures, concurrency/multi-threading, and performance optimization Practical experience with distributed caching, high-throughput messaging/streaming systems, and SQL/NoSQL datastores Comfort operating in cloud infrastructure (GCP or AWS) at scale Exposure to applying statistical, control-theory, or ML-driven techniques within production decision-making systems is a strong plus Real-time bidding / ad-tech domain experience is a big plus, but deep experience in adjacent high-stakes, low-latency domains (trading systems, large-scale ranking/recommendation, matchmaking, risk/fraud systems) is equally valued B.S. or M.S. in Computer Science, Engineering, or equivalent practical experience High ownership, self-motivation, critical thinking, and comfort operating with ambiguity Low-ego and nonpolitical — you'd rather get to the right answer than be the one who's right, and you take critical feedback in stride rather than personally Genuinely collaborative and team-oriented, with an open mind toward other people's approaches and the outgoing energy to work well across teams You've used AI coding assistants (e.g., Claude Code, Cursor, or similar) in real production work to accelerate design, implement, debug, and understand unfamiliar codebases. You have informed opinions on how best to leverage them You're curious about applying AI – whether that means using AI to monitor system health, triage issues or develop agentic workflows You hold yourself to a high bar of correctness and understanding of what you ship, even as these tools accelerate your pace Deep prior experience isn't required — genuine curiosity and a willingness to help shape how the team uses these tools responsibly are what matters most #LI-SSC What's Roku's approach to hybrid working? Roku fosters an inclusive and collaborative environment where teams generally work in the office Monday through Thursday. Fridays are generally flexible for remote work, except for employees whose specific roles or assigned office location require five days' a week attendance. What are some of the benefits?
