Full Job Description
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.

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 on-device and off device 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 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.


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.


  • 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.


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 largescale 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, DevOps/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.


Preferred

  • 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 multiproduct software ecosystems.
