TELECOMMUTE Principal (.net) Software Architect

We are looking for a Principal Software Architect to own end-to-end technical direction across all three platforms. This is a hands-on authority role: you will set architecture, govern the legacy-to-modern migration roadmap, drive cloud strategy, define integration standards, and mentor senior engineers - while remaining close enough to the code to lead meaningful design reviews and architectural decisions., Architecture & Platform Governance

• Own and evolve the cross-platform architecture spanning (C++/C# Windows applet, BHFTP transmitter, Proactive portal), (cloud SaaS, instrument fleet API, data pipeline), and Unity Next (QC engine, LIS/HL7 integration, Unity Connect middleware, peer-comparison analytics).

• Produce and maintain ADRs, HLD/LLD artifacts, and interface contracts - DCC folder layout, BHFTP protocol versioning, Azure AD/MSAL token flows, and LIS connectivity specifications.

• Govern security posture: TLS 1.2+ enforcement, secrets rotation via Key Vault, code-signing pipelines, AES-encrypted config management, and zero-PII telemetry compliance across all three platforms.

• Represent architecture to IT leadership, product, compliance, and field-service stakeholders; communicate decisions clearly to both technical and non-technical audiences.

Modernization & Cloud Strategy

• Lead frontend migration from MVC 5 + AngularJS (80+ components) to React 19 / Vite / Redux Toolkit / MSAL SPA; design new REST APIs in the AZURE Webservices tier.

• Own the Azure * AWS migration architecture; maintain AzureWebServices-AWS_migration skeleton in sync with every production change until the migration is decided.

• Define the cloud-native evolution roadmap - multi-instrument fleet APIs, data sharing, protocol distribution, and imaging system integration (ChemiDoc Go).

• Drive Unity Next modernization: cloud vs. desktop deployment strategy, LIS/HL7 connectivity hardening, scalable QC peer-analytics pipeline, and CLIA/ISO 15189 audit-trail architecture.

On-Instrument & Integration Systems

• Guide Applet architecture: C++ Win32 service host, IMonitoredEntity driver plugin model (Drives Info, Running Processes, System Info, ME Collect), DCC output contract, and AppletSoftwareUpdateManager CAB update pipeline.

• Govern cross-module constraints: Remote Client x64/.NET 4.8 and RemoteClient32 x86/.NET 2.0 must remain in parity; every BHFTP change requires coordinated updates in both transmitters.

• Own Salesforce ServiceMax integration architecture (ServiceMaxService Node.js + Health Reporter C#) and Unity Connect LIS/middleware specifications for Unity Next.

CI/CD, DevOps & Data

• Formalize CI/CD pipelines for the platform (no Jenkins file or pipeline YAML currently exists); design a multi-solution build matrix for the mixed .NET Framework / Node.js / React codebase.

• Govern the SQL Server data model (Proactive, Roles Permissions, Membership, InstrumentDataCollection, Logs databases) and drive a platform-wide secrets management strategy to eliminate hardcoded credentials.

• Mentor senior engineers across C++, C#, Node.js, and React; enforce coding standards and conduct architecture and code reviews.

Required

• 12+ years engineering; 4+ years as Architect or Principal Engineer

• Multi-tier platform experience in life sciences, medical devices, or industrial IoT

• C++/C# Windows services and on-device agent/applet software

• .NET Framework (Web Forms, MVC, Web API, WCF), Node.js Express, React 18/19

• Azure AD / MSAL / JWT bearer auth; Forms Auth and Windows Auth co-existence

• SQL Server: multi-DB schema design, query optimization, stored proc governance

• Custom protocol or binary/text network layer design (analogous to BHFTP over HTTPS)

• Azure cloud architecture (App Service, Azure AD); cloud migration planning

• Security: TLS 1.2+ enforcement, secrets rotation, AES config encryption, code signing

• CI/CD pipeline design for multi-solution .NET and Node.js codebases

• PowerShell deployment automation; IIS configuration and TLS/SSL certificate management

Preferred

• AngularJS-to-React migration at scale (50+ components)

• AWS architecture (ECS, RDS, Lambda, IAM) as migration target-state designer

• LIS / HL7 / middleware connectivity (Data Innovations, ASTM, FHIR)

• Clinical QC software: Westgard rules, CLIA, ISO 15189, CAP compliance frameworks

• Salesforce ServiceMax or comparable field-service platform integration

• ISL, TeamViewer, or remote-session / remote-desktop platform integration

• WPF / WinForms / VB6 co-existence and legacy code containment strategies

• Dual-binary codebase experience (x64/.NET 4.8 + x86/.NET 2.0)

• Redis; application-level caching and async job queue patterns

• GIS / Sharp Map or similar mapping components in enterprise web apps

• M.S. Computer Science, Software Engineering, or related discipline
