We are looking for a Senior Developer to help build and scale the cloud platform behind our connected industrial products, a production industrial-IoT system that ingests telemetry from tens of thousands of sensors in customer plants, decodes and enriches it, runs engineering calculations over the resulting time series, and serves the results to internal engineering teams and to customers.
You will work across that whole span: from LoRaWAN and Modbus device decoding, through time-series analytics, to the API and UI that engineers use every day.
This is a hands-on senior engineering role. You will own features end to end: design, implement, test, deploy through CI/CD, and support in production. You will also help set the technical direction, raise the engineering bar around testing and infrastructure-as-code, and mentor colleagues across a distributed team.
We expect a strong track record of shipping and operating production cloud software, with practical depth in the following.
