• Establish coding standards, engineering best practices, architecture guidelines, and reusable design patterns.
• Conduct architecture reviews, technical design reviews, and code reviews.
• Troubleshoot complex application, integration, performance, and production issues.
• Make architecture recommendations covering monolithic vs. microservices and synchronous vs. asynchronous integration approaches.
• Provide technical guidance and mentorship to mid-level and senior backend engineers.
• Work closely with architecture, infrastructure, security, product, and business teams throughout solution design and delivery.
• Communicate architecture decisions, technical risks, recommendations, and trade-offs to senior technical and non-technical stakeholders.
