Senior Software Engineer - Full-Stack (.NET, React + Native Apps)

Job Description

Location: Remote

Level: L4 Senior Software Engineer

ViewNexa is a streaming and app development platform for broadcasters, publishers, and media companies. We give them one workflow to ingest, manage, distribute, and monetize live, VOD, and FAST content across web, mobile, and connected TV experiences, including Roku, Fire TV, Apple TV, Samsung, iOS, and Android.

We are a product-engineering company: live encoding and transcoding, a high-scale backend platform on AWS, a React-based CMS, and native/CTV applications that have to work on real devices, not just in a browser.

ViewNexa ships experiences on web, mobile, and connected TV. This role exists to make that real: shared platform components, native or cross-platform clients, and the glue to our APIs, auth, telemetry, and playback stack.

You are a Senior engineer who is dangerous on C#/.NET and React, and who has actually shipped at least one native or living-room platform, not only responsive web.

\n
• Build and ship features across backend (.NET), web (React/TypeScript), and one or more client platforms.
\n
• Contribute to shared application architecture so web, mobile, and CTV are not three unrelated codebases.
\n
• Integrate clients with REST APIs, auth, cloud services, telemetry, device APIs, and media playback.
\n
• Debug the hard client problems: app lifecycle, memory, focus/remote navigation, fragmented device behavior, and playback edge cases.
\n
• Help the team choose where a native SDK, a cross-platform framework, or a web-based app is the right tool.
  
\n

\n
• Senior-level C#/.NET and strong hands-on React/TypeScript web development. You can contribute on both sides of an API in the same sprint.
\n
• Shipped native or cross-platform applications on at least one of: Android (Kotlin/Java), iOS (Swift), .NET MAUI/Xamarin, React Native, Tizen, Roku / BrightScript, tvOS, or similar living-room platforms. Shipping means store or production release, not a sample app.
\n
• Building clients that talk to real backends: REST APIs, authentication/authorization, cloud services, telemetry, device capabilities, and media playback.
\n
• Practical multi-platform engineering: platform SDKs, application lifecycle, networking, performance and memory constraints, deployment, compatibility, and device debugging.
\n
• Comfort working across backend, web, and client stacks without needing a translator.
  
\n

\n
• Connected TV (Roku, Fire TV, Tizen, webOS, tvOS, Android TV). CTV constraints are different from mobile, and this is high-value for us.
\n
• Media playback on-device (ExoPlayer, AVPlayer, Roku Video, HLS/DASH players) and the issues that come with it: buffering, DRM, live latency, captions.
\n
• .NET MAUI or a shared C# client architecture.
\n
• App-store / manufacturer certification experience (Roku, Samsung, Amazon, Apple).
  
\n

\n
• BrightScript/Roku channel development.
\n
• In-app purchase, entitlements, or SVOD/AVOD client flows.
\n
• Experience with a “write once, certify many” SDK model.
  
\n

You have a production app on a non-web platform, you can talk about remote-control UX or device fragmentation without flinching, and you still enjoy writing .NET and React.

You are web-only, or a mobile specialist with no interest in backend/web, or you have only wrapped a WebView and called it a native app.
