You only need the right attitude for this job and the ability to improve your .NET skills. That’s it.
This software house is ready to improve their existing product offering and work on Greenfield projects, so they would also like to hire someone (they’re looking for a mid and a senior-level developer) that’s worked on some new tech and is keen to be one of the go-to people in the dev team.
It’s not about how much code you can write; it’s about writing code that’s easy to maintain. The company has plenty of money to further invest in you and, if you like the idea of a developer job working in t-shirt and jeans (maybe a hoodie in the winter), then you might want to find out more about this opportunity. Your working hours are 9am-5pm and you can work from home as much as you like so long as you’re happy to pop into their office too.
