Senior Data Engineer, Python, Spark

What does the team work on? 

The mission of Roku’s Data Engineering team is to develop a world-class big data platform that empowers both internal and external partners to leverage data and drive business growth. The team works closely with business stakeholders and engineering colleagues to collect, transform and surface metrics that are critical to the success of new and existing initiatives.

As a Senior Data Engineer in the Viewer Product Device & Themed Experiences team, you’ll play a pivotal role in designing data models and building scalable pipelines to capture business metrics across Roku devices, Roku Powered TVs, web, and mobile clients. This work is essential to helping Roku understand which features resonate most with users and how we can continue to improve their experience.

 

What is the role? 

Roku pioneered TV streaming. We connect users to the content they love, enable publishers to build and monetise large audiences, and give advertisers unique opportunities to engage consumers. Roku streaming players and Roku TV™ models are available worldwide through direct retail and licensing partnerships with TV brands and pay-TV operators.

With tens of millions of devices sold across multiple countries, thousands of streaming channels, and billions of hours watched, a scalable, reliable and fault-tolerant big data platform is critical to our continued success.

 

How will I use AI at Roku? 

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 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.

This role is offered on a hybrid basis, based from our Manchester office, UK. 

 

What are the responsibilities of the role? 

• Building highly scalable, fault-tolerant distributed data processing systems (batch and streaming) that handle tens of terabytes of data each day, supporting a petabyte-scale data warehouse.

• Designing and developing robust data solutions, streamlining complex datasets into simplified, self-service models.

• Developing pipelines that ensure high data quality and resilience to imperfect source data.

• Defining and maintaining data mappings, business logic, transformations and data quality standards.

• Debugging low-level systems, measuring performance and optimising large production clusters.

• Taking part in architecture discussions, influencing the product roadmap, and owning new initiatives from concept to delivery.

• Maintaining and evolving existing platforms, introducing modern technologies and architectures where appropriate.
