Our people solutions span the entire employee journey, from salary payment to attracting, rewarding, and developing talent. Are you ready to join us?
About the role:
The Backend Developer (.NET/C#) – CMDB engineer is accountable for both the technical architecture and operational integrity of the platform governing infrastructure capacity, availability, asset lifecycle, and licensing across private cloud, public cloud, and datacenter environments.
We are primarily looking for a hands-on Backend Developer who is passionate about building integrations, services, and data solutions.
The ideal candidate has strong .NET/C# development skills, excellent SQL knowledge, and experience integrating enterprise systems through APIs.
Experience with ServiceNow CMDB, Asset Management, is considered an advantage.
This role combines technical leadership, data ownership, and operational execution to ensure that all capacity, availability, asset, and licensing data is accurate, complete, and actionable.
A significant part of the role focuses on designing, developing, and maintaining backend services, API integrations, and SQL-based data solutions that support CMDB, asset lifecycle management, capacity reporting, and operational decision-making.
It enables Product Owners and Platform Tribes to make informed, risk-aware decisions while ensuring the underlying systems, integrations, and data models are scalable, reliable, and aligned with enterprise architecture standards.
This role is ideal for an experienced backend engineer who enjoys solving complex data and integration challenges while working at the intersection of software engineering, infrastructure, and platform governance.
