ABOUT THE ROLE

We are looking for a Senior Software Engineer with experience in building scalable, reliable systems to help evolve and extend the infrastructure behind our Search and Recommendations platform. In this role, you’ll be part of a cross-functional, globally distributed team dedicated to creating fast, cost-efficient solutions that deliver relevant and seamless user experiences.
You’ll contribute to the design, development, and operation of critical systems that power real-time search and personalised recommendations for millions of users. You’ll help shape the roadmap for our next-generation architecture, drive standardisation and tooling efforts, and champion best practices in observability and resilience.
We are a fast-moving team with a strong engineering culture built on clear communication, thoughtful decision-making, and a shared commitment to delivering impactful solutions. Collaboration is fundamental to how we work — we invest as much in supporting each other’s growth as we do in building exceptional systems.

WHAT YOU’LL BE DOING

• Design, build, and operate platform infrastructure powering real-time search and personalised recommendations
• Work closely with machine learning engineers, data scientists, and infrastructure teams to scale our Machine Learning Platform
• Shape the roadmap for our next-generation architecture, including improvements in cost efficiency, observability, and resilience
• Drive tooling and standardisation, working with the broader platform teams to identify and align on shared approaches
• Design and implement multi-tenant systems and APIs that accelerate development, reduce coupling, and serve multiple teams across Roku
• Take ownership of quality and system performance from design through deployment and operation in production
