Spoke with Bill Marshall tonight, they lost a developer ~6 months ago and another developer ~2 weeks ago. They really need to hire a mid-senior dev quickly.
Strong C# skills – they are using/will be using AngularJS, WebAPI, Entity Framework (can be either a front-end developer or back-end developer; will cross-train).
They are also using Akka.NET, which apparently is pretty progressive. I.E.: if we have someone with this, they are pretty much hired.
