Senior Software Engineer - Backend

Job Summary

Senior Software Engineer to join the Payouts team where you will be responsible for designing and building mission-critical services that power revenue calculation and developer payouts on the Roku platform. This role requires strong expertise in distributed computing paradigms and the ability to deliver high-reliability backend systems with no margin for error. You will collaborate closely with product, engineering, and non-technical stakeholders such as Accounting and Treasury to ensure effective solutioning and seamless execution. The position offers significant exposure to the full payments lifecycle, from developer onboarding to revenue distribution. You will also provide technical mentorship to team members and drive engineering best practices across the team. This is an exciting opportunity to contribute to a platform that is scaling rapidly across domestic and international markets.

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 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.

Responsibilities

• Design and build APIs and backend services using Java
• Write clean, maintainable, and efficient code, ensuring adherence to best practices through code reviews
• Architect and develop scalable, distributed systems that support revenue calculation and developer payout workflows

• Participate in on-call rotations and incident response for mission-critical payment services
• Drive cross-team alignment and consensus on technical solutions and architectural decisions

• Bachelor's degree in Computer Science, Engineering, or a related field (or equivalent experience)
• 10+ years of experience in software engineering with exposure to scale and distributed services
• Expertise in developing APIs and robust backend services, with strong programming skills in Java or other JVM-based languages
• Strong problem-solving abilities and the capacity to work independently or collaboratively
• Excellent verbal and written communication skills
• Strong sense of ownership in driving projects from inception to user adoption
