Job description

Sympower is accelerating the global transition towards ‘net-zero’ by helping to build smarter, cleaner renewable energy systems. We are leading the way in smarter energy solutions for the energy transition.

With over one hundred employees and thirty nationalities represented in our organisation, our international team is driven by achieving together, focusing on impact and acting responsibly for our environment.

We are looking for a Team Lead to lead our Connections & IoT team. 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.



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.
