Our aim is to revolutionise the way organisations collaborate with robotic and autonomous systems and use the data they generate. We are driven by our determination to help defend our collective democratic values and by our strong belief that an elite group of engineers can make a big difference. We are ambitious, well-funded and building for the long-term.

If you are motivated by our mission and if you want to be part of a growing team of outstanding engineers, then we want to hear from you.

Requirements

About the role

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. While focusing on networking challenges, you'll be writing clean, maintainable code and implementing custom protocols on a daily basis. To help you decide if Arondite is for you, here's what you can expect:

You will join Arondite at a pivotal moment in the company’s journey. Our company’s future will be built on a foundation of exceptional engineers, people who find high-impact and technically challenging work engaging and exciting, and who consistently deliver outsized impact. You will collaborate with other brilliant minds to solve some of the world’s hardest and most important engineering problems.

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. The software you create will present complex information in an intuitive way to enable humans to task, control and supervise multiple robotic and autonomous systems.

In particular, you should apply if you have:

• 5+ years of Android development experience with a strong understanding of Kotlin and Java
• Expertise in low-level networking on Android, including working with sockets, WebSockets, and custom networking protocols.
• Deep knowledge of complex network architectures, including handling offline scenarios, caching strategies, and network optimizations
• Familiarity with Jetpack components and modern Android development best practices
• Ability to write clean, maintainable and testable code with unit and integration tests
• Strong problem-solving skills and ability to work in a fast-paced environment

It would be beneficial if you have:

• Experience with geo/mapping applications, including working with Cesium, Mapbox or custom mapping solutions
• Experience optimising for battery life and low power consumption
• Knowledge of video streaming protocols (RTSP, WebRTC) and optimizing media playback on Android
• Experience implementing and optimizing real-time push notifications
• Familiarity with Android security practices related to networking, encryption, and data protection
• Prior experience in industries such as navigation, transportation, or live video streaming

We believe in working closely with customers. As a result, this role will require the individual to hold a clearance or be willing to undergo UK security vetting to Security Check (SC) or above. This normally requires having continuous residency in the UK for at least 5 years.

Office vs Hybrid

We are focused on building a positive, collaborative engineering culture. As a result, we believe in making the office a friendly, comfortable and fun place to be and we try to work from the office where possible. Of course, there are times when it makes sense to work from home and that's OK. You may also need to travel to visit customers. But in general, you should only apply to join Arondite if you're excited to come into the office and work in person more often than not.
