Core Apps Developer (Node.js)

Unlike the standard Frontend and Backend development, this is different because the applications running on the devices has to be stable, reliable and long-term maintainable. This job is more about practice in C/C++ applications or similar. However, the underlying technology is JavaScript and TypeScript.

What will you do?

Our product allows developers to run any web or progressive web application on professional displays, TVs, or external players.

We are looking for a person who would develop so-called Core Apps for Samsung Tizen, LG WebOS, Android (TV), Raspberry Pi-like (Linux Alpine/Ubuntu/Fedora), Windows (Intel/AMD), BrightSign (Roku), ChromeOS, etc.

Core App is the main component which creates an adapter layer between our customers and display/device manufacturers. We also provide this product as a unified JS SDK interface to our customers.

The functionality that is under the hood includes, for example, video playback in various formats (codecs, containers, video and audio formats, framerate, resolution), streaming (YouTube, Netflix, UDP, RTSP, etc.), serial communication, payment terminals, receipt printers, QR/BarCode readers, File System (IndexedDB, Native), Cache API, Proxy configuration, Timezone, Brightness/Backlight, and many more.

There are countless specific use cases for end customers, e.g. professional advertising playlist players, dynamic menu boards connected to real-time API about prices, UI for set-top-box software streaming various streaming services (YouTube, Netflix, UDP, RTSP, etc.), interactive exchange rate boards for exchange offices and banks, interactive boards for displaying airport departures and arrivals, etc.

What do you get with this job opportunity?

• A unique opportunity to create software that will not only run on traditional web browsers, but on special devices such as professional displays from Samsung, LG, Sony, etc. or on external devices such as Raspberry Pi, ChromeOS, etc.
• Develop and maintain a unified JS SDK for medium and large companies that rely on the system as a critical development tool.
• Unique opportunity to work on a project that needs to be developed with precision accuracy and stability, supported by extensive automated testing as well as a long-term QA process. Projects are long term with a focus on quality and sustainability of development.
• Design system functionalities from scratch supported by years of experience and knowledge from senior developers.
• Your code will reliably power the largest display networks in the world - such as digital menus at McDonalds, Starbucks, BurgerKing and many more.

What can you do without?

• A very good knowledge of and motivation to use strict TypeScript typing.
• Experience and diligence to write testable code in the form of BDD or at least TDD.
• High level of thinking in abstractions used in application design.
• At least a theoretical understanding of a wide range of algorithms and especially design patterns.
