Key Skills

Amazon Athena, Amazon Simple Storage Service (S3), AWS, Continuous Integration & Continuous Delivery - CI/CD, Python Programming, Spark-SQL

Job Description

Opportunity

Join our small team in its growth phase with venture funding and a global customer base. We are a SaaS provider of rich video and speech data capture and analytics within the workflows of large field workforces (field engineers, field service, auditing, reporting, health and safety, sales, etc). Our customers are typically large multinationals in utilities, telecoms, manufacturing, facilities management, etc.

Technologies

Mobile and Web apps are used to capture/manipulate/view structured multimedia data. This data is stored, analysed and labelled on the AWS cloud. We use AWS CDK, GitHub Actions, AWS CodePipeline and a DevOps approach to achieve a high release cadence through our CD pipeline. We use Django rest framework and Postgresql to provide our primary REST API interface. Our web app is built using react. AWS SQS queues are then used to distribute work to a variety of processing systems/microservices which use a combination of commodity analytics APIs (e.g. AWS Transcribe, Google Speech, AWS Rekognition) and bespoke AI algorithms and models (e.g. TensorFlow) to provide advanced speech, image and video analytics. Our ML pipelines use AWS Lambda and Docker for model execution and AWS StepFunctions for orchestration.

As an ML Infrastructure Engineer you will closely collaborate with our data-scientists and platform engineers to roll out new features and implement industry best practices in ML Ops.
