Sennen is hiring a site reliability engineer to run and evolve our global offshore wind farm and renewable energy management platform.

Our vision is to transform infrastructure through technology, for a more sustainable world. Our mission is to become the go-to technology provider for renewable energy operators who are serious about safety, automation and efficiency at scale.

Deployments are to AWS - Sennen’s own account or a client’s account - entailing multiple databases and Docker services to facilitate our complex data integration processes, to drive our state-of-the-art applications. We're preparing for our largest solution to date, a multi-site five year partnership with EDF Renewables. In addition to our ongoing solutions for clients including London Array and Foresight, we have a healthy pipeline of new prospects and ambitious growth plans.

You'll provide the infrastructure, security and automation that underpins 24*7 production ops, ensuring we remain robust, nimble and efficient as we scale up. We have several existing infrastructure provision processes, as well as an ambitious roadmap of changes, and we’ll welcome your insights around the resources and evolution of the environments.

We offer a collaborative and friendly culture, with a flat structure. We can offer technical mentoring and guidance while you progress into delivering on more challenging objectives. You'll also have lots of autonomy, with plenty of time for research, to try things out and to complete projects. You'll find us open minded and supportive of your development and ideas.

Now is a great time to join us as we expand further, potentially becoming our lead on platform operations.
