Lead Backend Engineer / Developer (Python C++ GCP) London onsite to £150k

Are you a senior Backend Engineer who enjoys building platforms from the ground up? Do you thrive in start-up environments where you can own architecture, shape engineering culture and solve genuinely meaningful technical problems?

This is an opportunity to join an innovative technology start-up that has developed a world leading navigation platform designed to improve independence for people with visual impairments. Combining advanced GNSS positioning, computer vision and AI, the technology delivers centimetre-level accuracy in challenging urban environments, enabling users to navigate the world with confidence.

The core technology is proven. The next challenge is scaling it.

As Lead Backend Engineer, you'll take ownership of the company's cloud platform, defining the backend architecture that underpins a sophisticated ecosystem of mobile applications, computer vision systems and edge devices.

You'll lead the evolution from an existing Firebase implementation to a scalable, cloud-native platform on Google Cloud Platform, building resilient, low-latency services capable of processing high frequency location, sensor and image data from thousands of devices in real time.

Working alongside robotics, computer vision and AI researchers, you'll help transform cutting-edge research into robust production services, creating the APIs, infrastructure and engineering practices that enable the business to scale.

This is a genuine opportunity to influence technical direction, establish engineering standards and build the backend function from the ground up.
