At Proton we're bringing cutting-edge technology to the world of business-to-business distribution. It's a large market that offers an enormous opportunity for growth. The industry we serve accounts for trillions of dollars of revenue a year. It's a huge chance to have an impact by shaking up an industry that's still waking up to the promise of technology. We have a chance to really transform the way a huge number of people work for the better, and bridge the gap between amazing software tools and human expertise.

By becoming the source of truth for our customers' data, we're helping them make better decisions and be more effective. We’re looking for a mobile applications engineer to help us build a React Native mobile-first experience for our tool.

As the first member of our team working on a mobile product, you’ll help us build a rich and fully-featured tool on both Android and iOS using React Native that gives our users a smooth, seamless experience. You’ll work with our infrastructure team to define the mobile development toolchain, and work with technical leadership to make key foundational design decisions that will guide us for the years to come. You’ll work with our product team to define what it means to put Proton on a mobile device.

We think big and start small: you’ll also need to be nimble as we try and refine our mobile product, while not losing sight of the long-term goal. We want to build a true mobile-first application, including features such as on-device machine learning, that may require some diving into platform-native SDKs.

This engineering role sits within our user products team, joining engineering functions in server-side, machine learning, and frontend development. It reports to our CTO.

Our existing server-side infrastructure runs in a microservice architecture orchestrated by Kubernetes. Our backend is written in Python and Go, and our frontend is developed in JavaScript using the Vue framework. Our mobile experience will be built using the React Native framework, targeting Android and iOS. We plan to expand our development toolchain, including a robust continuous integration layer, to support our mobile vision.

As an early member of the company, you’ll have a chance to shape how we grow, making key decisions around technical choices, and defining our culture. We're working to build a sustainable environment where excellence sits alongside a recognition we operate in a system and a need to nurture learning at all levels.
