About the Role

We are seeking a Contract Senior Roku Engineer specializing in agentic development to deliver production-ready, certification-ready Roku applications through an AI-first delivery model. The contractor will design and operate a development workflow where AI agents perform the majority of planning, implementation, testing, debugging, code review, and documentation, with the contractor acting as solution architect, agent orchestrator, technical reviewer, validator, and final approver.

Responsibilities

  • Design, build, and operate an agent-led development workflow for Roku applications.
  • Define agent roles, instructions, tool access, permissions, context-management strategies, retry limits, quality gates, escalation paths, and approval boundaries.
  • Engineer the context, documentation, and tooling required to make agents effective on the Roku platform.
  • Implement and enforce human approval gates for high-risk, irreversible, security-sensitive, or release-related actions.
  • Operate all agentic tooling within BritBox-approved accounts and data-handling boundaries.
  • Maintain traceable, auditable evidence of agent activity, code attribution, test results, approval decisions, and significant manual interventions.
  • Monitor and report agentic tooling usage and inference costs against agreed budgets.
  • Review and approve all AI-generated BrightScript, SceneGraph XML, tests, configurations, and technical documentation before merge.
  • Identify and resolve hallucinated APIs, incomplete implementations, architectural problems, security risks, licence and IP provenance issues, regressions, and performance defects in agent output.
  • Personally validate applications on physical Roku devices and through the Roku development and certification toolchain.
  • Establish automated unit testing, linting, static analysis, regression testing, and release-readiness checks that agents can execute and act upon.
  • Enable agents to analyse requirements, create implementation plans, manage dependencies, produce code, run tests, review results, and correct failures within defined boundaries.
  • Intervene directly and implement by hand when agents cannot safely or reliably complete a task, recording the intervention and feeding it back into workflow improvements.
  • Improve agent instructions, tooling, context, and workflows based on observed failures, intervention rates, and evaluation results.
  • Report agreed metrics per milestone, including the proportion of implementation completed by agents, intervention rate, defect escape rate, and test coverage.
  • Collaborate with product, design, backend, video, and quality assurance stakeholders.
  • Deliver reliable, maintainable, performant, and certification-ready Roku applications against milestones, acceptance criteria, and success metrics agreed in the Statement of Work.

Requirements

  • Strong professional experience developing and shipping production Roku applications.
  • Advanced knowledge of BrightScript and Roku SceneGraph.
  • Strong understanding of Roku SDKs, platform APIs, application lifecycle, navigation, focus management, and remote-control interactions.
  • Experience with video playback, streaming workflows, application packaging, device deployment, debugging, profiling, and Roku certification.
  • Demonstrable experience delivering production software through autonomous or semi-autonomous coding agents, with agents completing meaningful planning, implementation, testing, and correction work.
  • Demonstrable experience making coding agents effective on niche or low-resource languages and platforms.
  • Experience designing single-agent and multi-agent workflows.
  • Strong experience defining agent instructions, tool access, permissions, context-management strategies, quality gates, retry limits, and escalation processes.
  • Ability to evaluate AI-generated code for technical correctness, maintainability, security, performance, licence compliance, and platform compliance.
  • Strong software architecture, debugging, automated testing, and code-review skills.
  • Experience with Git-based development, CI/CD, static analysis, and structured release processes.
  • Experience instrumenting and reporting code attribution, agent activity, and quality metrics in an auditable form.
  • Strong hands-on experience with agentic coding tools.
  • Ability to work independently as a contractor and deliver against milestones, acceptance criteria, and metrics agreed in the Statement of Work.
  • Strong written communication and technical documentation skills.
  • Willingness to provide evidence of agent-led software delivery through a portfolio example, redacted execution records, an open-source project, a live demonstration, or a paid practical assessment.
