Senior Software Engineer, Infrastructure / Efficiency / Productivity in Cambridge

Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and we aim to power every television in the world. We connect consumers to content, enable publishers to build and monetize audiences, and provide advertisers unique capabilities to engage consumers.

From your first day at Roku, you’ll make a valuable contribution. We are a fast-growing public company where no one is a bystander. You will gain meaningful experience across a variety of disciplines while delighting millions of TV streamers.

About the Role: You will be a SME and technical leader in engineering Infrastructure, productivity and enterprise tooling, partnering with globally distributed Engineering, Product and Security teams and systems.

What You’ll Be Doing: Roku seeks a world-class engineer to own the strategy, architecture, and long-term execution of engineering infrastructure, enterprise tooling, and AI-assisted workflow automation. This architect/strategist role drives org-wide improvements in engineering productivity, delivery throughput, quality, security posture, and cost efficiency by building platforms, working practices and automation (including AI/LLM-enabled capabilities) that scale across geographies and time zones.

Key Responsibilities:

• Define and lead an AI-first automation roadmap for Engineering Infrastructure and Enterprise Tooling (e.g., reducing waste, accelerating reviews, improving incident response, increasing release confidence).
• Architect and ship AI/LLM-enabled workflow automation across the SDLC (e.g. risk assessment, automated build, test and deployment, intelligent test selection, change-impact analysis, auto-triage of build/test failures).
• Establish policies and guardrails for AI usage in internal tools: data handling, prompt/response logging, model/provider selection, evaluation, fallback behaviors, and abuse prevention.
• Set technical direction and standards for globally used developer tools, including build systems; source code management, branching/release strategy, and self-service support tools.
• Architect and evolve CI/CD and build/test pipelines using Jenkins, Docker, and build systems (Bazel /BitBake/Yocto preferred) to support multi-site engineering environments.
• Own and scale test and quality workflows leveraging test management systems (e.g., TestRail or equivalent), enabling traceability, reporting, and release sign-off across distributed teams.
• Drive Jira workflow design and automation (templates, guardrails, integrations) for cross-org visibility and execution.
• Design and implement automation spanning Engineering, Product, Marketing, and Partners (e.g., launch readiness, certification/release checklists, partner onboarding, incident/change workflows).
• Replace manual coordination with durable automation and integrations that work reliably across regions/time zones.
• Embed secure-by-default controls into pipelines and tooling (access control, secrets handling, audit trails, policy enforcement), including for AI-enabled systems.
• Improve build/test performance and reliability (build times, test duration, flake reduction, pipeline stability) using measurable KPIs and operational rigor.
• Drive cost efficiencies across tooling/infrastructure (compute utilization, caching strategies, license rationalization including AI/runtime costs and ROI tracking).

This is a highly visible role and you will report directly to a Vice President of Engineering. Strong technical leadership with experience in consumer electronics devices is needed. Ability to collaborate with engineering and partner teams.

Own cross-team architectures and standards; drive adoption through influence, clear technical judgment, and sustained multi-quarter execution. Lead design reviews, mentor senior engineers, and unblock the hardest technical problems across distributed teams and systems. Provide long-term stewardship via roadmaps, operational maturity (runbooks/SLOs), and incident/postmortem practices for 24/7 global operations. Establish yourself as the go-to person for difficult problems.

We’re Excited If You Have:

• Bachelor’s in Computer Science or Computer Engineering, or equivalent experience.
• Prior experience at Staff, Principal, or Architect level.
• Ownership in platform/infrastructure, developer productivity, CI/CD, build systems, or workflow automation, including globally distributed teams and systems.
• Strong, hands-on knowledge of Git (workflows, branching strategies, release management).
• Jenkins (CI/CD pipeline design, scaling, reliability).
• Docker containers (reproducible build/test execution).
• Build systems (itBake/Yocto preferred).
• Jira (workflow design/automation, cross-team visibility).
• Test management systems (e.g., TestRail or equivalent).
• Demonstrated experience delivering automation at scale, including building platforms/components used by multiple teams.
• Strong systems thinking across security, reliability, performance, and cost tradeoffs.
• Excellent written communication (architecture docs, decision records, operating procedures).
• Experience building AI-assisted developer tooling (e.g., CI insights, test intelligence, code review automation, release risk scoring, incident copilots).
• Experience implementing evaluation/monitoring for AI systems (quality metrics, drift, offline test sets, human feedback loops).
• Extensive experience with software development on embedded Linux, multi-process architectures and IPC mechanisms.
• Experience working in large cross functional teams and ability to influence teams that don’t report to you.
• Ability to see the big picture while focused on short-term objectives and deliverables.
• Ability to multi-task and drive parallel projects and distributed teams with tight deadlines.
