IoT Cloud Engineer

As a (Senior) IoT Cloud Engineer, you will own the cloud side of our IoT Platform that ingests, routes, and observes every message flowing between our gateway fleet and our cloud services. You will work at the intersection of cloud infrastructure, messaging systems, data and IoT engineering, making sure our device-to-cloud highway is reliable, secure, observable, and cost-efficient as the fleet grows.

What you'll do

• Take ownership of our systems at the intersection of Cloud Services and residential IoT Gateways
• Operate and evolve our Kubernetes-based IoT Cloud Platform, including the deployment, scaling, and hardening of our connectivity and fleet services
• Develop and run our Eclipse Hono stack as the messaging backbone between gateways and the cloud
• Design, build and operate features around fleet management enabling the lifecycle of gateways from production line to field
• Integrate tightly with Mender to operate safe OTA rollouts across the fleet
• Build and own the observability pipelines for the IoT Platform and turn metrics into automated monitors, alerts, and self-healing mechanisms
• Build data pipelines and BI models to turn raw data into fleet insights
• Work collaboratively with product managers, data engineers, IoT engineers, and cloud engineers to create solutions enabling a scalable virtual power plant

What you'll need

• Bachelor's or Master's degree in Computer Science, Software Engineering, or related field
• 5+ years of experience building and operating cloud / distributed backend systems in production
• Strong hands-on experience with Kubernetes (ideally GKE) and modern cloud-native operations
• Solid understanding of MQTT and device-to-cloud messaging patterns at scale, including back-pressure, QoS, and fan-out
• Experience designing and running observability pipelines (logs, metrics, traces) for large-scale distributed systems
• Comfortable working with data and BI tooling — writing SQL, modeling data, and building dashboards
• Experience with CI/CD, IaC, and platform engineering practices
• Clear and effective communicator in English (German is a plus)

Nice to have

• Production experience with Eclipse Hono or a comparable IoT connectivity platform
• Familiarity with Mender or other large-scale OTA / fleet management systems
• Experience with SQLMesh and/or Looker (LookML) specifically
• Familiarity with Google Cloud Platform as the primary cloud
• Passion for climate tech and distributed energy systems

What they offer

• Work remotely (Germany-wide), with offices in Hamburg, Berlin or Munich
• EGYM Wellpass benefits for healthy balance
• Benefits and discounts with Futurebens
• Job bike leasing for flexibility and environmental impact
• Direct contact with core decision-makers
• Work with a talented, international team on climate tech
