(Senior) Backend / Platform Engineer (Go) (m/f/d)

KINEXON is a global location-based technology leader that develops groundbreaking hardware and software solutions for the Internet of Things (IoT). Our vision is to provide a real-time intelligence solution for a connected and automated world. Wherever assets, people or operations are in motion, we can improve and automate the underlying processes, creating powerful results for our customers.

THE TEAM AND ITS MISSION

KINEXON manages hundreds of active customer installations all around the globe running with different configurations in heterogeneous and demanding environments. To support this growth and ensure a standardized and stable deployment we have started to develop the KINEXON Runtime Platform, a solution responsible for deploying, running and monitoring the KINEXON software stack in a containerized environment.

• Design, implement, and maintain Go-based backend services and REST APIs, primarily in a microservices architecture
• Build and maintain internal tooling and automation in Go to improve developer workflows and platform operations
• Actively contribute to the design, operation, and evolution of our container-native infrastructure (Kubernetes-based)
• Collaborate on CI/CD pipelines (GitLab), including build infrastructure, runner fleets, and deployment strategies
• Support and partially own the Kubernetes platform: deployments, scaling, debugging, networking, and security concepts
• Operate and improve our observability stack (Prometheus, Grafana, VictoriaMetrics, Sentry): dashboards, alerting, and incident response
• Work with Infrastructure as Code (Terraform, optionally Ansible) to provision and manage cloud resources (AWS or Hetzner)
• Participate in architecture discussions, design reviews, and planning for future backend and platform changes
• Review code changes, ensure high code quality, and mentor other engineers where appropriate
• Document architectural decisions and present new features or infrastructure improvements to internal stakeholders
