Senior/Principal/Lead Developer

Enjoy architecting, creating a solution and making things happen? Want to take the lead and forge the way forward?

You need to work with amazing people, you need a new challenge, you need to work with Razor!

Microsoft Partner - Silver Application Development Gold Cloud Platform Crown Commercial Service Supplier

We are looking for a senior/principal/lead developer with personality. A developer who really knows their technical stuff and who can also articulate their ideas clearly has the ability to create simple elegant solutions and has got over the hump of the developer knowledge curve.

You may not have had the opportunity yet to flex those solutionising muscles or to be set free to lead a team or project but you are ready to take the leap. You may already be doing this on a day to day basis but need the next challenge or want the opportunity to build using the latest tools, technologies and techniques.

We don't expect you to know everything or have used all of the technologies we may have already used, we are learning all the time with new technologies and tools being added to our list all the time. The list below is probably already out of date.

This is the beauty of Razor, we are always moving with the technology keeping relevant and up to date so our partners stay up to date and relevant and importantly - so do you!

From developer to developer; no waffle. The stuff we do is pretty clever and it’s fun to work on. Here’s an idea of the types of technologies you’d be expected to work with:

  • .NET Core
  • C#
  • MVC
  • APIs
  • Azure; a lot more than just VM's and App Services
  • Xamarin(.Forms)
  • JavaScript / TypeScript
  • TDD
  • Python (for Machine Learning)

What to expect from us?

We pay you well and care about your development. We are flexible and offer flexible working hours. We understand that you are human and have a life outside of work. We don't expect you to slave away - we want you to be productive and happy.

We have a great working environment that is close to Sheffield train station and the centre of town.

If you are a recruiter and read this far, we feel that we may have wasted your time for a change 😉. Please don't contact us, we will contact you if we want to. We hope that you appreciate this and take heed.

The inside view of the Razor Sheffield Office

We will give you some of the best people to work with. People who you will be able to teach and who you will also learn a lot from.

We have UX and UI designers who create beautiful interfaces and provide you with clean HTML to work with.

The work we do is vast and varied and almost all targetted at Azure. We work on high scale concurrency ticketing platforms, IoT platforms with stream processing and big data analytics, Machine Learning, Natural Language Processing, cross-platform native mobile apps, bots, API's and of course websites.

We are constantly pushing the boundaries and have a clear vision of where we are going and who works well in our team. We are growing a culture with people who share our beliefs and want to enjoy the technology wave with us.

Razor is a place where you will be pushed to reach your full potential.

Are you ready to take the next step, to learn new things and to be pushed to the next level?
