Principal System Architect - MedDevice

About This Role

The Principal Architect is a senior individual contributor who defines, leads, and governs the software architecture vision across our device and digital ecosystem. This includes our on-device firmware, cloud services, analytics platforms, data pipelines, clinician and patient-facing applications, AI/ML enablement platforms, and operational software systems. The role drives architectural excellence, technology strategy, and systems coherence across R&D, product, clinical, data science, and IT, ensuring the on-device and off-device software ecosystem is secure, scalable, resilient, compliant, and aligned with product strategy and long-term business goals.

• Define the multiyear architecture strategy for all product 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.

• 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.
• Review key technical proposals, high-impact design decisions, and fundamental platform changes across R&D teams.
• Champion engineering quality standards for architecture, coding, testing, observability, and documentation.

• 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.

• 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.

• 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 architecting regulated or high‑reliability systems (preferably within medical, health tech, or similar domains).
• Mastery of architectural domains such as microservices, event‑driven systems, data pipelines, observability, Dev Ops/SRE practices, and cloud‑native technologies.
• Ability to operate as a senior‑level individual contributor influencing executive teams without direct authority.
• Exceptional ability to communicate complex technical concepts in clear, concise, and business‑relevant terms.
• Demonstrated success partnering with cross‑functional leaders across product, security, quality, regulatory, data science, and infrastructure.

• Experience with FDA, EU MDR, IEC 62304, HIPAA, and related regulatory frameworks for software as part of medical systems.
• Background supporting AI/ML platform architecture, model deployment, and clinical decision‑support software.
• Experience designing architectures that integrate with medical devices, clinical systems, EHRs, or healthcare data standards (FHIR, HL7).
• Prior leadership in organizations scaling complex multi-product software ecosystems.
