• AI Leadership: Architect and guide implementation of AI tooling and pipelines using LLMs, RAG, and MCP, including retrieval design, model orchestration, safety guardrails, and backend integrations. Establish standards for data validation, analysis, and anomaly detection; implement automated quality gates to safeguard log and telemetry integrity at scale. Define coding and documentation standards for Python-based services and AI-assisted development; conduct code and design reviews to uphold engineering rigor. Develop performance testing and monitoring strategies; instrument metrics and health endpoints to drive continuous optimization.
• Technical Delivery: Create and maintain software solutions within the team’s domain; own epics and tasks and delegate work as needed to ensure timely delivery.
• Mentoring and Coaching: Lead onboarding and accelerate ramp-up through structured curricula, shadowing, and clear success metrics. Provide educational code/design reviews and formal training; serve as a Subject Matter Expert to unblock teams, elevate standards, and develop future senior engineers.

What should I know about Roku's culture?

Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the company's success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. We're independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust. In short, at Roku you'll be part of a company that's changing how the world watches TV.

We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two-part idea. We come up with the solution, but the solution isn't real until it is built and delivered to the customer. That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
