Senior Product Manager - Core Platform

About the Role 

guardsix is a European cybersecurity platform built to safeguard society by empowering lean SecOps teams across Regional MSSPs and regulated mid-market organizations. 

At the core of our product is the platform layer — how data is ingested, normalized, stored, queried, and made usable at scale. 

We are hiring a Senior Product Manager - Core Platform to lead this area and define how our platform is built, deployed, and operated in real customer environments. 

You will shape how guardsix SIEM: 

Ingests and processes high-volume data reliably 

Maintains consistent, usable data models across sources 

Delivers fast, predictable query performance 

Scales across customers and environments 

Is deployed, configured, and operated successfully in production 

This role sits at the core of the product. The strength of our platform, and how well it runs in real environments, determines product reliability, scalability, and customer trust. 

The workplace will be based in Copenhagen or remote from Europe. You will report into VP, Product Management.
