Senior/Principal UI Framework Developer

Huawei Finland Graphics and GUI lab is looking for a Senior/Principal UI framework developer to join the team!

Huawei is developing its own operating system for a wide range of embedded devices, to be used for smartphones, cars, laptops, home entertainment devices, etc.; Named Open Harmony OS (OHOS). Open source on gitee.com. Product name is Harmony OS Next. The operating system has been show-cased this summer, currently in public beta, with a first phone product expected later this year in PRC market. ArkUI is the UI framework of OHOS (open source at [https://gitee.com/openharmony/arkui%5Face%5Fengine>). Our Helsinki-based team is responsible to deliver major parts of the framework’s front-end: application state monitoring, UI render and smart UI update logic, related developer APIs. Hence, the ‘reactiveness’ of the framework. We implement the state management part of ArkUI runtime in ArkTS, with interfacing to C++ thru the ArkTS runtime. The pipeline and UI components are implemented in modern C++. The OHOS application programming language is ArkTS, Huawei’s own flavor of TS (essentially TS with some JS language elements depreciated). ArkUI has its own DSL and accompanying UI compiler.

You will be working with our team to develop new front-end features for ArkUI, to re-architect and optimize existing ones. You will be touching code every day. Sometimes you contribute straight to the next release, sometimes you will need to convince stakeholders about your solution with a PoC first. All ArkUI code is open source, PRs need to be submitted to gitee (link above). You will join our Finland team of ~12 senior to expert -level software engineers and a department of 100+ working on ArkUI, and 3000+ engineers working on OHOS.
