Director - Application Performance Engineering

Our products are built on Windows .NET and SQL Server and managed in AWS. Our web UX stack is built on jQuery and some areas use AngularJS. Our middle tier is in C# and we build our infrastructure on an extensive set of Restful APIs. We build native iOS and Android apps, and are starting to leverage Flutter and Dart. For select infrastructure components we use Python extensively, and use Tableau for analytics dashboards. We use Redshift, Aurora, Redis Elasticache, Lambda, and other AWS products to build and manage our complete service, moving towards serverless components. We deal with billions of API calls, millions of records in databases, and terabytes of data to be managed with all services we build that must run 24x7 at 99.99% availability.  

Key Responsibilities:

• Performance Optimization: Lead the design and implementation of performance tuning strategies for our .NET-based product and the underlying SQL Server databases. Utilize tools and techniques to analyze and enhance application performance, reducing latency and improving response times.
• Technical Leadership: Guide and mentor a team of performance engineers, providing technical direction and fostering a culture of continuous improvement. Collaborate with developers, QA engineers, and infrastructure teams to identify and resolve performance bottlenecks.
• Monitoring and Analytics: Implement and manage performance monitoring solutions on AWS to track application and database performance metrics. Analyze performance data and logs to identify trends, potential issues, and areas for improvement.
• Scalability and Reliability: Develop strategies to ensure that product can scale effectively to meet growing user demands. Collaborate with SRE on capacity planning and disaster recovery strategies to maintain high availability and reliability.
• Performance Testing: Oversee the development and execution of performance testing plans, including load testing, single user testing, and benchmarking. Ensure that performance requirements are met throughout the development lifecycle and be responsible for certifying release from a performance stand point.
• Stakeholder Communication: Communicate with Leadership team and provide regular updates on performance metrics, issues, and improvements. Be able to communicate and work with customers on on-going performance issues.
