- You are comfortable with Linux administration, networking, and distributed systems
- You have hands-on experience with infrastructure-as-code tools such as Terraform or CloudFormation
- You have worked with configuration management tools like SaltStack, Ansible, or Chef
- You have experience with container and orchestration technology (Docker, Kubernetes, Helm) in production
- You understand monitoring and observability and have worked with tools like Datadog, Prometheus, or Grafana
- You communicate effectively in asynchronous, remote-first environments

What the job involves
- As Site Reliability Engineer (all genders) you will join a deeply technical squad of around 6 engineers responsible for the reliable operation and infrastructure behind the Intelligent Grid Platform (IGP). The platform runs across 100+ customer instances on Kubernetes, spanning Azure, Open Telekom Cloud, and on-premise environments
- You design, build, and maintain the platform foundation: cluster provisioning, deployment pipelines, observability, secrets management, and infrastructure-as-code. You partner closely with the new Operations team that will run IGP day to day for customers, providing them with the tooling, monitoring, and automation they need to operate confidently
- You work in a squad together with other SREs, reporting to the Engineering Manager
- You maintain Kubernetes clusters across multiple clouds and on-premise environments, ensuring they are reliable, secure, and cost-effective
- You develop and maintain infrastructure-as-code (Terraform, SaltStack) to manage 100+ customer instances with layered configuration
- You design and maintain observability (monitoring, alerting, SLOs) so that production issues surface early and are resolved quickly
- You own and evolve secrets management, certificate automation, and security tooling across the platform
- You reduce operational toil through automation, better tooling, and solid runbooks
- You participate in incident response, root cause analysis, and drive follow-ups so the same issues do not reoccur
- You collaborate with development squads and the Operations team to improve the overall reliability of the IGP
Our take
As the world transitions to sustainable energy, millions of new wind energy systems are being integrated into power grids. As well as the number of new consumer solutions, such as electric charging stations is also rapidly increasing, and the integration of these new systems is putting a strain on distribution grids.
Envelio is a cloud-based smart grid platform providing a solution to this challenge. The Cologne-based company has developed the Intelligent Grid Platform (IGP), a software assistance system that transforms power grids into digital, flexible interactive smart grids. Through IGP grid operation management can be carried out digitally at a quicker, more cost-effective pace.
Born out of the Institute of High Voltage Technology at the RWTH Aachen, Envelio has since grown a steady customer base for itself and expanded on an international scale. Recognised as a clean-tech software company, Envelio is driving the change to sustainable energy.

Diversity, Equity & Inclusion at envelio
Ann-Sophie Kuttner (Senior Manager Culture & Development)
- At envelio, our commitment to Diversity, Equity, Inclusion, and Belonging (DEIB) is a journey, not a destination. This journey is all about creating an environment where every individual feels empowered to thrive, contribute, and evolve alongside us. We are not perfect, but we are committed to growing every day — by listening to each other, staying informed about the latest research, and learning from our experiences. We acknowledge that we don’t have all the answers, and are open to feedback and new ideas.
- Unconscious Bias Training: All interviewers in the recruiting process receive ongoing training to recognise and reduce unconscious bias. We regularly update this training based on the latest research and feedback from participants.
- Come as You Are: We believe in the power of authenticity. There’s no dress code because we want everyone to feel comfortable expressing themselves. Whether it’s barefoot shoes or sneakers, a shirt or a hoodie.
- Growth Talk: Our monthly Growth Talk covers a range of topics, including DEIB. These sessions help to keep an open discussion in the company.
- Gender-Inclusive Language: We remain committed to using inclusive language and regularly review our communication strategies to ensure they reflect our evolving understanding of inclusivity.
- Annual Diversity & Inclusion Survey: Assuming is different from knowing. Instead of assuming that every envelian feels included, we conduct an annual survey to understand where we are at and what can be improved.
