The position
We are looking for talented Senior Full Stack Software Engineers to join the Connections & IoT team, part of the engineering side of Sympower. This team is focused on how we can connect to our customers’ automation systems in the most painless and user-friendly way while keeping the end-to-end system scalable and secure. We are currently reshaping the technical foundations of this domain — you have a chance to have a direct influence on the future design. This is a full-time position.

The Connections & IoT domain has responsibilities across different stacks:

• Embedded (software-close-to-hardware) stack is running on IoT devices (Java and Rust), acting as a gateway between Sympower cloud services and customer automation systems accessible via local connections.

• Cloud connections stack is running in the cloud (Java), acting as a gateway between other Sympower cloud services and customer automation systems accessible via the internet.

• Cloud components stack is running in the cloud (Kotlin and Java), providing APIs via gRPC and/or REST.

• And finally, the front-end stack is powering the user interfaces we have (React, TypeScript).

Why join our Software Engineering team? Our current engineers share their reasons in this video.
