This role requires a powerful blend of legacy and modern technology expertise with deep proficiency spanning C/C# Windows services on-device applet Framework architectures (Web Forms MVC Web API WCF) Express and cutting-edge frontend ecosystems like React 18/19. A strong candidate will demonstrate extensive mastery of enterprise identity and access management specifically Azure AD MSAL and JWT bearer authentication alongside the ability to manage co-existing legacy Forms and Windows Authentication models. From a data and infrastructure standpoint the architect must excel in SQL Server multi-database schema design stored procedure governance query optimization and PowerShell deployment automation alongside robust IIS configuration and TLS/SSL certificate management. Furthermore the position demands a rigorous approach to platform security including TLS 1.2 enforcement automated secrets rotation AES configuration encryption and secure code-signing pipeline design. Finally the candidate must possess proven experience designing custom network protocols or binary/text network layers coupled with the ability to engineer robust CI/CD pipelines for complex multi-solution codebases.

Key Responsibilities and Experience Include:

• Serve as the technical authority by conducting rigorous code and design reviews enforcing engineering standards and mentoring senior engineers across C C# and React technologies.
• Formalize enterprise DevOps practices by designing and implementing green-field CI/CD pipelines capable of supporting Framework and React technology stacks.
• Drive the end-to-end architecture and technical strategy for the Instrument Intelligence Platform encompassing remote monitoring applets cloud-native SaaS solutions and Unity Next clinical QC benchmarking engines.
• Establish and govern a unified cross-platform architecture ensuring seamless interoperability scalability and technology alignment across the ecosystem.
• Author and maintain Architecture Decision Records (ADRs) High-Level Design (HLD) Low-Level Design (LLD) documents and interface/data contracts to support platform consistency and governance.
