End client - Service base Industry

Experience -  12+ Years

ROLE PURPOSE

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.

KEY RESPONSIBILITIES

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.
