Job duties
As part of the Web Performance team, your role will involve assisting with performance instrumentation and observability, as well as aiding our teams in addressing any issues related to performance. Addition responsibilities may include:

- You’ll document and distribute knowledge of performance best practices across engineering at Etsy.
- We believe strongly in using both quantitative and qualitative methods to guide decisions. To that end, you'll not only use our in-house analytics tools to gather information and gain insights, but you’ll also help build those tools.
- You'll also use Etsy's Continuous Deployment architecture to push code to production early and often (and you'll probably push in your first week here).
