The requirement is immediate and what we are looking for is as follows:
The candidate should:
- be well versed with both front & back end development. Just being versed with one wont do. Nope. Has to be both. Period.
- have had "project lead" experience & should be able to conceptualise a project from start to finish. Leaving it mid way just isn't our style...unless it's a boring conversation or a McAalo Tikki Burger...both suck equally!
- be able to think on their feet, think out of the box, push the envelope, look at the big picture, find the devil in the details, lead by example & most importantly, should be willing to go back to the drawing board. Here, thats all the office jargons we could put up here...rest needed censoring.
- have good communication skills. We don't need the best. As long as you can recite 'ba-ba black sheep' without a pause or two, it should do!
- be healthy, fit & willing to work some days from office and some days from home. To us, work life balance is very important & so is paying 50% office rent during the pandemic!
