Prinicipal Software Architect

• Serve as the technical authority by conducting rigorous code and design reviews, enforcing engineering standards, and mentoring senior engineers across C++, C#, Node.js, and React technologies.
• Formalize enterprise DevOps practices by designing and implementing green-field CI/CD pipelines capable of supporting mixed .NET Framework, Node.js, 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.
• Enforce platform security and compliance standards, including TLS 1.2+, automated secrets rotation through Key Vault, secure code-signing pipelines, AES-encrypted configurations, and zero-PII telemetry compliance.
• Lead the modernization of legacy applications by transforming ASP.NET MVC 5 and AngularJS interfaces into highly scalable React 19 Single Page Applications (SPA).
• Design and implement modern REST APIs within the cloud tier to enable scalable, secure, and extensible platform integrations.
• Architect and maintain the dual-state Azure-to-AWS cloud migration framework while defining the roadmap for cloud-native multi-instrument fleet APIs and imaging system integrations.
• Manage dual-binary codebase constraints by maintaining feature parity and stability across x64/.NET 4.8 and legacy x86/.NET 2.0 transmitter environments., * Serve as a hands-on technical authority, balancing high-level cloud strategy and stakeholder engagement with deep technical involvement in code reviews, solution design, and architectural decision-making.
• Lead the transition from legacy on-device systems, including Win32 services and custom binary protocols, to modern cloud-native architectures while ensuring business continuity and platform stability.
• Communicate complex cross-platform technical concepts effectively, translating architectural decisions into clear, actionable roadmaps for IT leadership, product management, compliance organizations, and field-service stakeholders.
• Champion engineering excellence through security-by-design principles, rigorous documentation standards, quality-focused development practices, and continuous improvement initiatives.
• Mentor and develop engineering teams by fostering a culture of technical growth, collaboration, architectural discipline, and adherence to best practices across the software development lifecycle.

We are seeking for a 12+ years of software engineering experience, including at least 4 years acting as a Principal Engineer or Software Architect managing multi-tier platforms within life sciences, medical devices, or industrial IoT domains. This role requires a powerful blend of legacy and modern technology expertise, with deep proficiency spanning C++/C# Windows services, on-device applet software, .NET Framework architectures (Web Forms, MVC, Web API, WCF), Node.js 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.
