Company Details

Altitude Angel is an aviation technology company which creates global-scale solutions to enable the safe integration and use of fully autonomous drones into global airspace. Our purpose-built cloud platform supports both U-Space and UTM, and delivers market-leading services to drone operators, manufacturers and software developers. Our innovative solutions for ATM enable them to access a rich source of real-time airspace, environmental and regulatory data which is expertly customised to the specific operation.

Look up and you probably don’t see much. Maybe a plane, the occasional helicopter and, of course, the odd bird. Not for long…

We at Altitude Angel envisage a future where drones are set to revolutionise the lives of everyone on the planet, so we’re building the platforms to ensure drones can fly safely alongside other, more traditional, forms of aviation.

Since 2014 we’ve been steadily growing our team beyond our Reading HQ, whilst expanding our network into Europe, attracting some of the finest minds and top talent from the worlds of aviation, software engineering and product development.

Our platform is now used in 152 countries across the globe enabling over 50,000 safe drone flights every month, including everything from transport of life saving medication in sub-Saharan Africa to coffee and burger delivery in the Republic of Ireland.

With drones becoming more and more prevalent, we’re looking for individuals who are eager to help us build and deliver the solutions which have the potential to change the world.

About the role:

Widely regarded as a technical leader in our field, our national foundation technologies are deployed internationally by governments, civil aviation authorities and air navigation providers to meet the needs of an emerging industry.

Our mobile apps play an important role in providing operators in the field with the tools to intuitively understand when and where it is safe to operate. They translate complex airspace shapes, rules and regulations into a digestible model, providing the tooling to request and obtain access to regulated airspace and/or private land. They inform the operator about potential and actual conflicting traffic and interacting with airspace management systems and authorities – whether a human or machine interface.
