• Lead the team in making high-level design decisions and technology selections, documenting trade-offs and rationale
• Produce and maintain architecture artifacts, including an architecture description, component design documentation, architecture diagrams (C4, DoDAF, UML), and architecture decision records (ADRs)
• Translate business requirements and product and program goals into technical designs that meet both functional and non-functional criteria
• Develop proofs of concept and prototypes to validate architectural choices
• Evolve the architectural principles, patterns, and standards used for JRE
• Lead architecture and pull-request reviews, providing constructive feedback on designs and significant implementations
• Ensure JRE meets key quality attributes such as scalability, reliability, performance, security, maintainability, and operability
• Manage technical debt and inflation, strategically incorporating the remediation of legacy debt into the product roadmap
• Partner with product management to align technical strategy with business goals
• Collaborate closely with industry partners to understand their requirements and align with JRE modernization goals
• Mentor and coach engineers on design patterns, systems thinking, and architectural reasoning
