Arondite is looking for an experienced Android Engineer with specialised expertise in low-level networking to join our innovative team. You should have 5+ years of Android development experience with a strong command of Kotlin and Java, and deep knowledge of complex network architectures including handling offline scenarios and network optimizations.

You will have ownership and autonomy from Day One. There is a flat hierarchy at Arondite. From your first day, you will directly influence the design, functionality, and direction of Arondite’s product offering. We hire the best people and give them extremely high levels of autonomy; the sky is the limit for an individual with the right ambition.

You will design and build software to enable autonomous systems to collaborate, process vast quantities of data, and take meaningful action. You will iterate closely with and enhance the capabilities of end users who do globally impactful work.
