What this job asks for AI summary
A principal/staff-level backend engineering role focused on defining and evolving the foundational architecture for an HCM platform — covering shared services, APIs, data models, and platform libraries consumed by HR, Recruiting, Benefits, and Payroll product teams. The work spans distributed systems design in .NET Core, service decomposition, event-driven patterns, and modernization of legacy platform dependencies, with compliance, auditability, and scalability as core constraints. Best suited to a seasoned engineer with a history of setting cross-team architectural direction on large-scale, regulated enterprise systems.

Why we read it this way (7)
The title is not given; the role is framed around architecture and platform leadership across multiple teams and domains. The requirements explicitly call for 3+ years at a 'senior, staff, or principal level' and cross-team architectural authority, which supports a Staff-level classification despite the title being absent.
The alt SOC (11-3021, Computer and Information Systems Managers) is noted because the role carries significant cross-team technical direction and standards-setting, though the primary day-to-day work described is hands-on architecture and engineering (building services, APIs, libraries), keeping it in 15-1252.
AI-assisted engineering practices are listed in the required qualifications block with firm language ('Experience applying AI-assisted engineering practices'), so it is treated as a hard gate. The more specific AI concepts (anomaly detection, rule augmentation, model inference pipelines, decision-support systems) appear in a secondary block with 'Familiarity with' framing and are marked preferred.
Angular is listed under a secondary bullet ('Front-end experience supporting or integrating with Angular applications') that reads as context/nice-to-have rather than a primary gate for this backend/platform architecture role.
Event-driven architecture, NoSQL, and batch/hybrid processing appear in a secondary 'nice to have' style block and are marked preferred.
No compensation, degree requirement, or employment type is stated in the posting.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): AI-assisted engineering.
