Ai First Fullstack Engineer Jobs in Austin, TX (NOW HIRING)

When you work at Roku, you work on a platform that real people use: You can show off the fruits of your labor to your family and friends and see it in your favorite stores' electronics departments. As a member of the Roku Products Engineering team, you will design and develop embedded software systems that enable us to build world-class products, with Roku "inside" as their OS. To make this possible, you will work on the Roku OS on new technologies and develop new features while keeping our existing code clean and performant. Additionally, you will work with product managers to accommodate shifting demands and schedules; collaborate cross-functionally with our QA and other development teams; and build solutions with external hardware component vendors. 

We are an AI-first engineering organization. We actively leverage AI tools and agentic workflows to amplify our velocity, quality, and innovation. We expect every engineer on this team to view AI as a core part of their daily workflow not an afterthought, and to continuously push the boundaries of what's possible with AI-assisted development. 

We value individuals who take pride in their ability to navigate ambiguity, collaborate, and partner with both internal and external teams, including those with demanding engineering standards and a passion for building the highest-performing, best-in-class consumer products. We aren't kidding that Roku is a place where no one is a bystander. If you want to work on a team where you will be surrounded by the best talent building things used by millions of people, if you want a tech culture that just works, you should reach out.

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 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 create and drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you.

We are looking for a talented engineer to join our New Products Development Team working on the Roku TV program! You will be responsible for core tasks ranging from Roku OS feature development, SoC partner collaboration, third-party API integration, code maintenance, design scalability solutions to help onboard new factories, supporting our QA and Channel certification teams, and everything else involved in our end-to-end product development and release cycles. You will be expected to use AI coding tools daily to accelerate your work and elevate the quality of your output. To succeed in this challenging role, the following expertise is strongly preferred.

• Roku OS feature development, leveraging AI tools to accelerate coding, debugging, and iteration
• Code maintenance and scalability solution design and development
• Partner with internal QA and development teams
• System-on-a-Chip (SoC) integration and platform bring-up
• Third-party API integration
• Working end-to-end product development and release cycles
• Critically evaluating AI-generated code for correctness, security, and performance in embedded contexts
• Contributing to team AI productivity - sharing effective prompts, workflows, and tooling improvements

AI-First Required Qualifications

• Proven AI-assisted coding experience - Regular, hands-on use of AI coding tools (e.g., Claude, Copilot, Cursor, OpenCode) in real development work, with specific examples of AI tools used in production workflows
• Prompt engineering and AI code review skills - Ability to write effective prompts, iterate on AI output, and critically evaluate AI-generated code for correctness, security, and performance; can identify hallucinations, subtle bugs, and security vulnerabilities
• Agentic coding tool proficiency - Hands-on experience with agentic coding harnesses (e.g., Claude Code, Cursor, Copilot, Codex) with specific examples of driving an agent through a non-trivial engineering task, verifying output, and recovering from agent errors
• AI threat awareness - Understanding of how AI can be exploited (prompt injection, data leakage, etc.) and ability to code defensively against these risks
• Builder mentality toward AI - Actively pushes AI boundaries, adapts quickly to new tools, and views AI as core to their workflow rather than optional 

AI-First Preferred Qualifications 

• Portfolio of projects where AI tools were central to the development process
• Experience shipping production features integrating LLMs, embeddings, or AI capabilities
• Deep embedded systems domain expertise combined with AI fluency to amplify output and velocity
• Contributions to AI tooling or productivity - custom agents, internal tools, scripts, or workflows that accelerate team output 

Core Engineering Qualifications 

• Bachelor's or master's degree in Computer Science, Computer Engineering, Electrical Engineering, or other relevant fields
• 8+ years of relevant software development experience
• 4+ years C/C++ coding experience
• System-on-a-chip (SoC) development and integration preferred
• Experience developing/debugging on Linux or Android-based embedded platforms 
• Good understanding of Linux system and kernel concepts, multithreading primitives, Linux tools, libraries, and open-source development
• Experience with streaming audio/video platforms, graphics, and industry standards
• Ability to excel in a fast-paced engineering environment
• Ability to communicate with candor and effectiveness
• Experience working collaboratively with cross-functional teams
