Expertise in designing secure software platforms, including TLS 1.2+, certificate lifecycle management, Azure Key Vault, encryption, secure code signing, and secrets management.
Experience designing custom communication protocols, network services, binary/text messaging layers, and distributed systems.
Demonstrated success implementing enterprise CI/CD pipelines supporting complex, multi-solution application ecosystems.
Key Responsibilities
Define and drive the technical architecture and long-term technology strategy for the Instrument Intelligence Platform, including remote monitoring solutions, cloud-native SaaS applications, and clinical quality benchmarking systems.
Serve as the organization's technical authority by establishing engineering standards, conducting architecture and code reviews, and mentoring senior engineering teams across C++, C#, Node.js, and React technologies.
Lead modernization initiatives that transform legacy .NET Framework, Windows Services, and AngularJS applications into scalable, cloud-native React-based solutions.
Design secure, scalable REST APIs and integration frameworks supporting instrument connectivity, enterprise systems, and cloud services.
Establish enterprise DevOps practices by designing and implementing CI/CD pipelines that support hybrid technology stacks across .NET Framework, Node.js, and React applications.
Define and govern cross-platform architecture standards to ensure scalability, interoperability, maintainability, and long-term technology alignment.
Produce and maintain Architecture Decision Records (ADRs), High-Level Designs (HLDs), Low-Level Designs (LLDs), interface specifications, and architectural governance documentation.
Champion security-by-design principles by enforcing authentication standards, encryption, certificate management, secrets rotation, secure code signing, and regulatory compliance requirements.
Lead Azure-to-AWS migration initiatives while defining the roadmap for cloud-native services, fleet management APIs, and imaging platform integrations.
Maintain compatibility across legacy and modern application environments, including x86/.NET 2.0 and x64/.NET Framework 4.8 deployments, while driving long-term modernization.
