Computer Science, Software Engineering, or related discipline ## Description 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. ## Related Videos - [Architectures that we can use with .NET](https://www.wearedevelopers.com/videos/935-architectures-that-we-can-use-with-net) - [CI/CD with Github Actions](https://www.wearedevelopers.com/videos/856-ci-cd-with-github-actions) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers)
