About This Role

The Principal Software Architect is a senior individual contributor who defines, leads, and governs the software architecture vision across our medical and non‑medical digital ecosystem. This includes cloud services, analytics platforms, data pipelines, clinician and patient‑facing applications, AI/ML enablement platforms, and operational software systems. This leader drives architectural excellence, technology strategy, and systems coherence across R&D, product, clinical, data science, and the intersection of our products with IT.

The role ensures that the software ecosystem is secure, scalable, resilient, compliant, and aligned with product strategy and long‑term business goals. Operating at an enterprise level, this role influences senior stakeholders across engineering, product, quality, regulatory, and security while maintaining deep technical credibility.

Key Responsibilities

Technology & Architecture Strategy

• Define the multiyear architecture strategy for all off device software systems, spanning cloud, application, data, integration, and ML/AI infrastructure.
• Establish architectural principles, reference architectures, and guardrails that support reliability, performance, interoperability, maintainability, and regulatory compliance.
• Ensure holistic systems thinking across software platforms, clinical workflows, device interactions, and data flows.
• Evaluate emerging technologies and provide strategic recommendations for adoption, modernization, and platform evolution.

Architectural Leadership & Governance

• Lead cross‑functional architecture forums and governance processes, ensuring consistent patterns, shared services, and disciplined decision‑making across teams.
• Drive architectural clarity early in product development by guiding systems decomposition, API strategies, data models, and cloud architectures.

• Champion engineering quality standards for architecture, coding, testing, observability, and documentation.

Cross Functional Influence & Collaboration

• Partner with product management to translate business needs into scalable technical strategies and architectural roadmaps.
• Collaborate with security, privacy, regulatory, quality, and clinical teams to ensure designs meet medical device standards and software compliance requirements.
• Serve as a trusted technical advisor to senior leadership, articulating architectural options, trade‑offs, risks, and business impacts.
• Bridge off‑device and on‑device systems to ensure seamless end‑to‑end workflows, data flows, and system integrity.

Execution Support & Technical Leadership

• Provide architectural oversight throughout the SDLC, guiding teams during concepting, detailed design, implementation, and release.
• Drive standardization, reducing duplication and accelerating development velocity through clear architectural patterns.
• Mentor engineering leads and architects across the organization through thought leadership, coaching, and technical review.
• Lead technical investigation and resolution of complex systemic issues, spanning data, scalability, reliability, or workflow interactions.

Qualifications Required

• Bachelor’s degree in Computer Science, Software Engineering, Systems Engineering, or related field; advanced degree preferred.
• 15+ years of progressive experience in software engineering or architecture, with deep expertise in large‑scale distributed systems, cloud architectures, and modern application platforms.
• Proven experience…
