HTML/CSSMentoring should come naturally to you, as well as finding the right balance towards process and documentation.
Highlights:
1) You will be working on interesting technical challenges in a product centric and open-source driven environment. The role requires a good knowledge of Algorithmic Design and Architecture, Data structures, OOPS Concepts, server less architectures and complex problem solving skills.
2) You will help set a very high bar on code quality.
3) You will take ownership of product features from conception to implementation, testing deployment and support.
4) A lot of freedom on when and where you work from - just get stuff done.
5) You will open source as much as possible, and blog about cool things that you learnt and built.
6) You will help define who we become as a company.
7) You will get stock options in line with silicon valley standards.
Caveats:
1) We have a strict no-divas rule. There are a lot of smart engineers on the team but no one with an attitude / superiority complex.
2) If you think writing tests for your code, writing docs, doing customer support etc are not your cup of tea, this isn't the right role for you.
3) Similarly if you're viewing this just as a 20-40% increment opportunity over your current compensation, this isn't the right role or company for you.
This role can be the growth opportunity of a lifetime for anyone who has been operating as a backend lead and wants to grow into a full stack
