We’re looking for a proactive and technically strong Support Engineer to support the full lifecycle of apps on Titan OS.

You’ll work closely with key app providers (e.g. AppleTV, HBO Max, Spotify) not only during initial onboarding, but throughout the ongoing lifecycle of their apps: across new platform releases, evolving technical specifications, and new TV model launches.

This role combines technical troubleshooting, partner support, and coordination across internal teams. You’ll help ensure apps continue to perform reliably as the platform evolves, while also improving documentation, processes, and overall developer experience.

Key Responsibilities:

App Lifecycle Support & Integrations

• Act as a technical contact for app partners across the full lifecycle (onboarding, updates, and new platform releases)
• Support partners in adapting their apps to new Titan OS versions, device generations, and technical requirements
• Troubleshoot issues and identify root causes across app, platform, and device layers
• Collaborate with QA, engineering, and partners on investigations and issue resolution
• Communicate technical topics clearly to both technical and non-technical stakeholders

Developer Experience, Documentation & Tooling

• Improve onboarding and integration processes through clear documentation and guidance
• Create and maintain technical documentation, guidelines, and integration best practices
• Support and help define tools that improve debugging, inspection, and validation workflows
• Contribute to maintaining compatibility with other Smart TV platforms
• Support app interaction features (e.g. key mapping, deep linking, and platform integrations)

Platform Quality & Certification

• Support app certification and ensure compliance with platform requirements (e.g. playback performance, input handling)
• Help validate app behaviour across devices and platform versions
• Identify recurring issues and drive improvements in platform requirements, tooling, or processes

Requirements

• 2-5 years of experience in technical support, software engineering, or systems integration (ideally on Smart TV or connected devices).
• Proficiency with JavaScript (ES6+), HTML5, and CSS3, including at least one JavaScript framework, with an understanding of how modern web application architecture works.
• Expertise in debugging Web Applications, with proficiency in JavaScript analysis and browser-based tools (WebInspect/Chrome DevTools).
• Basic understanding of cloud infrastructure (AWS, Azure, etc.) and how it impacts the app lifecycle and data communication.
• Strong problem-solving skills across multiple layers (app, platform, and device).
• Strong written and verbal communication skills, including technical documentation
• Ability to collaborate with internal teams and external partners
• Detail-oriented with a structured approach to problem-solving and process improvement

Nice to Have

• Experience with Smart TV platforms (e.g. Titan OS, Android TV, Tizen, WebOS)
• Familiarity with OTT/video streaming, DRM, or playback technologies
• Experience with debugging tools, test frameworks, or automation
• Understanding of CI/CD or release processes

Why This Role

This is a great opportunity to work at the intersection of engineering, product, and partner integration, supporting high-profile apps and ensuring they continue to perform across an evolving Smart TV ecosystem.
