Department: Engineering

Reporting to: VP of Product Engineering

We’re looking for world-class developers to join our team in building our Desktop applications. You’ll use the latest technologies and frameworks to build a modern, responsive and highly-performant application providing multiple products in the privacy and security space.

We provide the scaffolding and release vehicles into which multiple product units contribute to creating a super-app of privacy and security services for Windows, Linux and Mac. We:

• Build the foundations of the app into which other product units then contribute functionality like VPN and DNS services, password management, and anti-malware.
• Define core architecture, including guardrails to enable multiple teams to contribute safely.
• Build core functionality in areas such as authentication, user subscriptions, in-app purchases, local and push notifications, in app messages and more.
• Configure and manage our build systems.
• Operate our test pipelines.
• Pick test frameworks and guide other teams on using them well.
• Coordinate releases to customers, typically once every two weeks or more frequently.
• Coordinate technical documentation.
• Provide expertise relating to the Desktop platform as a service for other teams.
• Are accountable for:

• Quality: especially performance, app stability, battery-life
• Velocity: ultimately measured by how quickly we can deliver value to customers
• Meeting SLAs for the build and CI systems
• Satisfaction of other engineers with their ability to contribute to our Desktop app

• Ensure your code follows modern development practices.
• Ensure the app has a clean, simple and robust architecture to enable other teams to easily contribute code.
• Ensure our application functions correctly and looks great on a wide range of Windows, Linux and Mac OS versions and hardware.

• Ensure your build and test pipelines are fast and stable.
• Provide high quality code reviews for your team and other contributors to the code base.
• Able to identify and communicate problems with technology, investigate potential causes, propose solutions/next steps, and proactively inform the team of changes.
