Lead end-to-end system architecture, including system design, APIs, data models, security, scalability, observability, and cost optimization.
Own the production performance and reliability of systems serving large user bases.
Design secure solutions involving healthcare data, Protected Health Information (PHI), and payment workflows.
Architect applications using the MERN stack (MongoDB, Express.js, React, Node.js) and modern cloud infrastructure.
Work with AWS, GCP, or Azure, along with Kubernetes, CI/CD, Infrastructure as Code (IaC), networking, and secrets management.
Drive decisions on microservices, event-driven systems, integrations, and build-versus-buy strategies.
Identify and resolve production bottlenecks across performance, scalability, and availability.
Establish engineering standards, reference architectures, and reusable design patterns.
Participate in coding, architecture discussions, design reviews, and code reviews.
Mentor senior engineers and develop future technical leaders.
Required Qualifications
