GenAI Engineer in London

At Vyntelligence, we are reimagining how work gets done in the deskless world. Our platform enriches expertly-curated short videos — captured before, during, and after work — with AI-powered automated workflows. We own the world's largest dataset of this kind, enabling field users and customers to make smarter, more efficient decisions about their assets and operations. Our purpose is to deliver transformative commercial and environmental outcomes, helping global clients across utilities, telecoms, retail and energy improve pricing accuracy, speed up delivery, ensure safety, and maintain compliance.

Mobile and Web apps are used to capture, manipulate and view structured multimedia data. This data is uploaded to our public cloud systems and analysed using machine learning, computer vision, LLM (and Vision-Language models) and other technology. Our AI decision-making agents combine with various integrations to support decisions for users, and in other systems, to drive important field workflows. We are continually enhancing the data collection and computer vision and AI capabilities of our platform.

Our team includes multiple specialists who are developing and improving our AI capabilities, as well as a wide range of other software engineers to provide our full offering. We use GitHub, GitHub Actions, code-pipeline and CDK with a DevOps/GitOps approach to achieve a high release cadence through our CD pipelines. We use Django Rest Framework and PostgreSQL to provide our primary REST API interface. Our web app is built using React. We also have Android and iOS native apps.

Our platform is primarily AWS and has a pluggable architecture coordinated using queues. Work is distributed to a variety of processing systems and smaller services. We use a combination of commodity analytics APIs and bespoke AI algorithms and models to provide advanced multi-step multi-modal speech, image and video analytics. We use AWS Lambda, Docker, ECS, API Gateway, AWS Step Functions and other tools to implement various video processing, ML and other AI applications.

As you would expect, our system also provides various collaboration, administration, management and security-related features around the central video capture and analytics. We offer both shared and dedicated deployments of the software; by defining all of our infrastructure as code we are able to easily deploy dedicated copies of our entire system into dedicated VPCs for our large customers. Many of our customers have stringent security requirements around their video data, so we use a variety of modern systems to provide security and monitoring across our networks and applications.
