Apply today and help shape a smarter and more sustainable industry.

As a Senior Data Engineer, you are the glue that makes it all possible, from raw sensor measurement to actionable insight for the customer. You will drive the development of:

• Stream processing pipelines to process incoming sensor data and persist it in our time series database
• Advanced real-time detection of machine faults and energy waste, powered by machine learning
• Batch processing pipelines and analytics microservices that provide personalised advice to our customers over our GraphQL API
• Tooling for state of the art machine learning operations (MLOps), serverless and event-driven architecture and cloud services in AWS.

Being part of a scale-up, you are proactive in prioritising and solving the needs of our fast growing group of customers.

Our AWS stack is focused on ingesting raw sensor data into Kafka, stream processing it using Kafka Streams and Flink and exposing it through Clickhouse. Batch processing is done using Prefect and Fargate, on-demand services are deployed using Lambda. We have a powerful internal GraphQL API to expose data to end users, managed by Hasura.

We do Scrum with 2-week sprints, sprint planning and retrospective sessions. Our stand-ups are at 9:30 and if you're not there you can chime in over Meet. We know how important it is to get in the zone and write beautiful code so we schedule most meetings in the morning and keep the afternoon quiet (we try). We work from home about 70% of the time, but we enjoy meeting each other in the office regularly.

You will be in the Data team, which along with IoT and Platform make up the technology departments. The course is determined by quarterly goals, set collaboratively with the teams themselves. We don't believe in silos, so you will work in a multidisciplinary team with colleagues from multiple departments, represented by a product manager.
