• Identify technology and strategic growth opportunities that enable Iru to grow as a business and rally the organization behind these choices by providing clear rationale and technical vision. 
• Become an authority on the technologies of your team with the ability to answer questions to guide other developers and inform business management
• Collaborate cross functionally with distributed teams; much of our workforce is remote
• Work closely with engineering counterparts on other projects to ensure consistent architecture and product alignment
• Help drive quality by working with teams to promote modularized code that is testable, performant, and easy to maintain with multi-staged validation plans
• Design and deliver systems that require research on what is 'possible' rather than simply relying on past experience
