You’ve implemented patterns like message-passing and CQRS, and understand how they contribute to the stability of complex systems. You’ve built performance monitoring and diagnostics into your software, so your systems can give the operations team the information they need to support and maintain your code without having to call the developers in every time they have a problem.

Skills & Requirements

Our existing codebase is primarily .NET/C# .net. We have legacy systems running ServiceStack, DotNetOpenAuth, NServiceBus, WebAPI, ASP.NET MVC, NHibernate, LINQ to SQL and other open-source .NET frameworks. Our front-end is HTML, CSS and jQuery; there’s some classic ASP code written in server-side JScript, and our back-end data store is Microsoft SQL Server.

We’re building new tech stack using cloud native technologies AWS Lambda, AWS API Gateway, .NET Core, ReactJs. Sometimes, we’ll be building new features on top of existing code – in which case familiarity with AWS services, ReactJS and .net Core is obviously an advantage. When it comes to integrating the new stuff with the old stuff, we use clean interfaces and APIs around our legacy systems, to make sure things keep evolving away from monolithic web applications towards a decoupled, scalable service-oriented platform.

Again, we have a “wish list” – but we don’t expect you to tick every box on it; these are skills we need as a team, and we know we’ll be lucky to find them all in one person.

  • NET code – from DataReaders to You know your way around REST APIs, ASP.NET MVC, LINQ, NServiceBus, IoC containers, Moq and NUnit. You use tools like ReSharper, Reflector, TeamCity, and SQL Compare. You understand testing. Unit tests, integration tests, acceptance tests, A/B tests. You know when they’re useful, and what they can teach you.
  • JavaScript – and not just the good parts. jQuery, prototypes, timeouts and closures. You know your AJAX from your JSON and your with() from your eval(). You’ve ideally have some experience with frameworks like ReactJs, and know a bit about building single-page
  • The web. You’re fluent in HTML5 and CSS3. You understand HTTP; you know your GET from your POST, and how to use techniques like HTTP caching to deliver responsive front-end
  • PowerShell, T-SQL or Python – they’re not your tools of choice, but you know sometimes they’re still the best tool for the job. You’ve experimented with systems like NodeJS, Redis or Memcached, and have some ideas about how they might fit into a predominantly Windows-based hosting environment. When someone says a server’s running slowly, you can think of a dozen things to try before turning it off and on
  • You’re comfortable with DevOps, configuration management and managing infrastructure as code. Most of our stack runs on Amazon Web Services; as well as EC2 instances, RDS and Elastic Load Balancer, we’ve got code using things like Amazon API Gateway and Elastic Transcode, so any experience with the AWS platform and services would be
