Senior .NET Developer

Role Summary

The Senior .NET Developer will design and build the core verification APIs for a cloud-native platform that centralizes and automates employment and work-requirement verification.

This role focuses on backend API development, integration with external verification sources, and the implementation of policy-driven business rules that can evolve as program requirements change. A key emphasis of this role is ensuring that verification logic is transparent, maintainable, and auditable, rather than tightly hard coded into services.

Build secure and scalable API integrations with external verification sources, including:

State and federal data providers
Third-party systems
Stubbed or mock services during early delivery phases

Implement policy-driven business rule patterns that clearly separate verification logic from core service code
Enable business rules to be read, updated, and tested without invasive code changes
Design traceable rule evaluation flows that support explainability (inputs rules outcomes)
Support automated, partial, and manual verification paths based on rule outcomes
Apply API security best practices for systems handling sensitive data (authentication, authorization, data protection)
Collaborate with:

Cloud platform teams on infrastructure, CI/CD, and runtime environments
Integration teams on API gateways and enterprise integration patterns
Product, policy, and data governance stakeholders to translate requirements into technical solutions

Produce clear technical documentation for APIs, business rules, and integration contracts
