Junior ASP.NET Developer

Quant Capital is urgently looking for a junior asp.net Fullstack Web Application Developer to join our high profile client.
Our client is the world leader in Market data management systems, with clients globally such as most of the major investment banks. Their team in Tonbridge is at 63 and rapidly expanding. As a developer you will work in small teams consisting of a BA, Implementation consultant, web and windows developer and a PM.

All current development is built using React JS for the client side backed by WebAPI (C#) REST Endpoints. For managing application state, we use Redux and Immutable JS. Existing features which are in active maintenance use the Backbone Marionette framework, but due to the impressive performance and productivity benefits of React, we have chosen to gradually phase out these older frameworks. We use open source JavaScript libraries extensively, most notably Lodash, Plotly Charts and React Virtualized.

You will focus on a third-generation .NET web application suite, although legacy solutions also comprise of ASP.NET WebForms.

Day to day the FullStack Developer will:

• Design and implement custom mission critical services and applications using the .NET Framework and SQL technologies.
• Take a project through the entire lifecycle of analysis, design, coding, testing, implementation and support.
• Design, build, and maintain efficient, reusable, and reliable .net and React code.
Junior Full Stack Developers MUST have:
• 2:1 Computing Science degree from an EU University
• ASP.NET MVC
• Production experience of an ORM – Ideally Dapper or Entity Framework 6
• Backed by ASP.NET WebAPI endpoints in C#. The candidate should have secure knowledge of JavaScript and/or C#. Although we don’t require React experience, any exposure to structured frameworks such as React, Ember or Angular will be beneficial. Experience with SOLID principals, IoC Containers such as AutoFac, or SoA experience will make you stand out.

This is a young and dynamic team with a range of people. They look for good technical skills as well as excellent communications skills and offer the latest technology in a cutting edge market.

My client is based in Tonbridge

ES6, React, Redux, ASP.NET, WebAPI, C# Developer
