Platform Engineer (DevOps)

Job Overview

We're hiring a Platform Engineer (DevOps) to join our team in Aarhus. Own the infrastructure that runs AI at ecommerce scale. We're looking for a Platform Engineer who thrives at the intersection of cloud infrastructure, developer tooling, and operational reliability. This isn't a maintenance role - you'll be architecting and owning the platform that enables AI agents to process millions of product records, run nightly enrichment pipelines, and push structured data to channels used by some of Europe's leading ecommerce brands.

Key Responsibilities

• Cloud infrastructure & reliability


• Design, build, and maintain scalable infrastructure on Google Cloud Platform


• Ensure high availability and performance across enrichment pipelines handling 1M+ product records


• Implement monitoring, alerting, and observability across all services


• Own incident response and postmortem processes


• CI/CD & developer experience


• Build and maintain CI/CD pipelines that enable fast, safe deployments


• Develop internal tooling that improves developer velocity


• Manage containerisation and orchestration (Docker, Kubernetes)


• Define and enforce infrastructure-as-code practices


• Data infrastructure & integrations


• Support event-driven architecture for real-time and nightly enrichment jobs


• Ensure robust data flows between integrations (Shopify, PIM systems, feed channels) and our AI layer


• Maintain and optimise SQL and NoSQL databases for performance at scale


• Security & compliance


• Own secrets management, access controls, and least-privilege policies


• Ensure infrastructure meets security and data compliance requirements relevant to enterprise customers

Technologies You'll Work With

Cloud & infrastructure: Google Cloud Platform - compute, storage, networking, managed services, GitHub actions and Helm for continuous deployment, Docker & Kubernetes for containerisation and orchestration, Grafana Cloud for observability.

Pipelines & data: Temporal workflow orchestration, Event-driven architecture and message queues, SQL and NoSQL databases, BigQuery data-warehouse, Nightly batch processing and real-time pipelines.

Backend context: Golang and Python services (you don't need to write them, but you'll support the teams that do), API infrastructure and OAuth integrations.

Required Qualifications

You have:

• 4+ years of professional experience in DevOps, platform engineering, or cloud infrastructure


• Ability to work onsite in Aarhus (remote not accepted)


• Deep hands-on experience with Google Cloud Platform or equivalent (AWS/Azure)


• Strong understanding of CI/CD, containerisation, and infrastructure-as-code


• Experience designing and operating event-driven or pipeline-heavy systems


• A track record of improving reliability, observability, and developer experience


• Comfort making independent decisions on infrastructure - you own it, you improve it
