Join BESTSELLER as a Senior Platform Engineer to help shape the future of retail and e-commerce analytics.

You will play a pivotal role in developing and maintaining the infrastructure behind Appretio, our flagship AI-powered platform transforming merchandising processes across Retail, Wholesale, and E-commerce. With a strong mandate to innovate and a vibrant team culture, this role offers an exceptional opportunity to impact millions of customers worldwide.

YOUR TEAM
You'll join our dynamic Merchandising Solutions department, comprising over 20 highly skilled professionals, including data scientists, software engineers, and application developers. Our team thrives on collaboration, innovation, and continuous learning, united by a mission to deliver state-of-the-art analytics and AI solutions that empower BESTSELLER's global operations. Your primary workplace will be at our vibrant office in Aarhus.

YOUR NEW ROLE
As Senior Platform Engineer, you will be a part of the technical leadership of the Appretio platform itself - the foundation our data scientists, engineers, and developers rely on every day. You will shape architectural direction and build the self-service capabilities and golden paths that let our teams move fast without reinventing the wheel.

YOUR IMPACT
In this senior role, you will:

  • Design, build, and maintain the Appretio's cloud platform, primarily on AWS, with infrastructure-as-code (Terraform, Helm, Kubernetes).
  • Design self-service capabilities and golden paths that make the paved road the easy road for product teams, raising developer productivity across the department.
  • Prepare Appretio for brand adoption - multi-tenancy, isolation, cost attribution, and scale.
  • Partner with data science, engineering, and application teams to keep the platform roadmap grounded in real developer needs.
  • Contribute to our agentic development environment.

YOUR BENEFITS
Joining BESTSELLER means working in a vibrant, innovative environment where your decisions make immediate, tangible impacts. You will:

  • Engage with an expert, collaborative team committed to innovation and excellence.
  • Access comprehensive professional growth opportunities, including specialized training programs and international exposure.
  • Benefit from extensive support for ongoing education, certification, and skill development.

YOUR PROFILE
You are an experienced platform or infrastructure engineer with a product mindset, strong architectural instincts, and a track record of making other engineers more productive. You are at home both at the whiteboard and in the code. Your expertise includes:

  • A degree in Computer Science, Engineering, or a related discipline.
  • Expertise in public cloud architecture, with AWS strongly preferred (Azure or GCP also valuable).
  • Extensive hands-on experience with Kubernetes, Terraform, Helm, and infrastructure as code.
  • Experience designing or scaling internal developer platforms, self-service tooling, or golden-path frameworks.
  • Strong architectural judgement - able to weigh trade-offs across cost, security, reliability, and developer experience.
  • Strong communication skills, able to collaborate effectively across technical and non-technical teams.

The following qualifications would also be advantageous:

  • Experience with data platforms (Databricks, Snowflake) and streaming (Kafka).
  • MLOps or ML-platform experience - running AI and machine-learning workloads at production scale.
  • Experience building multi-tenant SaaS infrastructure
  • Interest or experience in agentic AI development workflows (e.g. Claude Code or containerised AI agents).
