This role will apply proven software architecture and systems engineering principles to define requirements, evaluate design alternatives, manage interfaces, resolve competing priorities, and reduce technical and operational risk. The architect will lead or support technology exploration, modeling, proofs of concept, prototyping, and technical down-selection. They will also guide system integration, verification, performance, resilience, and scalability testing to demonstrate that platform solutions meet product, business, security, privacy, and regulatory requirements. Working as a senior member of the technology organization, this architect will collaborate with company leadership, product teams, quality assurance, cybersecurity, alliance partners, vendors, and other stakeholders. The architect will serve as an authority and advocate for the consistent application of platform architecture principles, engineering standards, and modern backend development practices across teams. Where you come in Provide architectural direction for strategic technology and product decisions involving server-side, backend, and cloud platforms. Define target-state and reference architectures for distributed services, APIs, data pipelines, event-driven systems, integrations, and shared platform capabilities. Translate customer, product, business, regulatory, security, and operational needs into platform requirements and architecture patterns. Design systems for scalability, availability, resilience, performance, security, privacy, observability, maintainability, and cost efficiency. Define service boundaries, domain models, API contracts, integration patterns, data ownership, and platform interfaces. Evaluate architectural tradeoffs involving consistency, availability, latency, throughput, complexity, delivery speed, operational risk, and cost. Establish standards and guidance for service development, API design, cloud infrastructure, data management, deployment, configuration, and system integration. Partner with cybersecurity and privacy teams to incorporate identity and access management, encryption, secrets management, auditability, threat modeling, and secure-by-design principles. Develop strategies for meeting applicable medical-device, privacy, security, and software lifecycle requirements throughout technology development and product commercialization. Identify, document, track, and actively reduce technical, operational, security, project, and business risks. Lead architecture reviews and provide clear, actionable guidance to engineering teams. Evaluate new platform technologies and determine when adoption will accelerate development, improve reliability, or create a competitive advantage. Lead proofs of concept and technical evaluations using modeling, prototyping, experimentation, and measurable acceptance criteria. Guide capacity planning, performance engineering, reliability testing, disaster recovery, business continuity, and subsystem and system integration testing. Define and promote observability practices, including logging, metrics, tracing, alerting, service-level objectives, and production health monitoring. Collaborate with DevOps, Site Reliability Engineering, and infrastructure teams to improve deployment automation, environment consistency, operational readiness, and incident response. Communicate complex architectural decisions, alternatives, risks, and recommendations clearly to engineering teams, product stakeholders, and senior management. Maintain architecture documentation, decision records, interface specifications, system diagrams, and technical roadmaps. Independently plan, prioritize, and manage architecture initiatives while providing periodic progress, risk, and decision updates to management. Take a direct technical leadership role in high-priority or complex platform initiatives when business needs require it.
