• Evaluate architectural tradeoffs and document technical decisions through ADRs, diagrams, prototypes, benchmarks, and other appropriate artifacts 
• Work with Requirements Engineers to develop detailed agile user stories and validation criteria 
• Provide technical leadership and mentorship to software engineers through design reviews, code reviews, and architectural guidance 
• Lead software design decisions across all levels of development, ensuring solutions are scalable, maintainable, and production-ready 
• Demonstrate advanced knowledge of enterprise design patterns and Well-Architected Framework to drive sound technical decisions 

What You’ll Need to Succeed:

• Bachelor’s or Master’s degree in Computer Science, Computer Engineering, or a related field 
• 8+ years of relevant experience in software development and architecture 
• Excellent communication skills, with the ability to clearly convey products, deliverables, analyses, and/or issues to groups outside of your team or those who are unfamiliar with the topic
