• Standards & Best Practices: Establish and enforce engineering standards across the organization, including coding guidelines, testing frameworks, CI/CD pipeline strategies, and security-by-design principles.
• Cross-Functional Partnership: Collaborate deeply with Product Management, Engineering Managers, and Pharmacy Operations to ensure technical architectures align with long-term business goals and clinical requirements.
• Regulatory & Security Compliance: Partner with the InfoSec team to architect systems that natively support strict healthcare compliance standards (HIPAA, SOC2), ensuring patient data privacy and secure messaging.
• Performance & Reliability: Spearhead initiatives to optimize system performance, reduce latency, and improve database efficiency within our PostgreSQL and AWS infrastructure.
• Technology Evaluation: Continuously evaluate new tools, frameworks, and AWS services, running proof-of-concepts (POCs) to determine their viability for improving the FuzeRx ecosystem.

• Education: Bachelor's degree in Computer Science, Software Engineering, or a related technical discipline.
• Experience: 10+ years of progressive, hands-on experience in software engineering and systems design. 3+ years operating at a Staff, Principal, or equivalent senior architectural level, driving technical initiatives across multiple teams.
• Industry Experience: Extensive background in building and scaling distributed, high-throughput, and highly available B2B SaaS or transactional systems.
• Shift / Site Specific Requirements: Standard business hours; expected to serve as a Tier 1 technical escalation point for critical architectural outages. [Insert Remote/Hybrid/On-site details].

• Other Desired Experience: Exceptional communication skills with the ability to explain complex technical trade-offs to non-technical executives and stakeholders. A strong bias for action and pragmatism over architectural purity.
• Measurable Expertise: Proven ability to design and implement complex distributed systems, optimize complex relational database queries, and establish automated deployment pipelines.
