You'll analyze and interpret large volumes of performance data to characterize application behavior while proactively scanning for potential problems. Once an issue or bottleneck is identified, you'll build simulations to test your findings, and upon confirmation, you'll clearly explain it to Technical Architects and guide them towards a solution. We believe in having the guts to push limits and break barriers to make things happen, continuously learning and reinventing ourselves for maximum impact, never giving up. Your duties will include:
• Explaining complex findings to a variety of technical audiences.
