Engineering foundations
The MARFELD technology stack
A structured view of the infrastructure, data layers and integration standards behind our HR software and applicant tracking solutions.
Core tiers
Three layers, one system
Each tier is designed to be understood and reviewed on its own terms.
Tier 01
Interface components
The front-end layer where HR and recruitment teams review candidates, manage vacancies and follow hiring workflows in a consistent interface.
Tier 02
Data storage
A structured persistence layer that holds candidate, role and workflow records with integrity checks built into how data is written and read.
Tier 03
Integration connectors
Defined connection points that exchange data with the wider organisational systems an HR or recruitment team already relies on.
Architecture standards
Protection, boundaries and reliability
Our architecture separates responsibilities into clear modules so that data protection, security boundaries and infrastructure reliability can be reviewed independently. Access to candidate information is scoped to the roles that need it, and each layer is built to keep records consistent even when individual components are under load.
Modular enterprise patterns guide how the system grows: new capabilities are added as bounded modules that connect through documented interfaces, so the platform remains predictable for IT teams validating its design and for the HR organisations relying on it day to day.
