We’re working with an established digital agency that is looking for a Junior to Mid-Level Full Stack Developer to join its growing development team.

You’ll be joining a highly experienced technical environment and working within a client-focused delivery team, building and enhancing digital solutions for a broad portfolio of existing customers.

This is a great opportunity for a developer who already has some commercial software development experience, enjoys working across the full stack and wants to continue developing within a supportive and technically strong team.

The Role

You’ll work on small-to-medium-sized projects across a range of client accounts, contributing throughout the development lifecycle.

Your responsibilities will include:

  • Developing full-stack web applications using C# and modern .NET technologies
  • Building and integrating Web APIs
  • Working with SQL Server and relational databases
  • Front-end development using JavaScript and TypeScript
  • Working with CMS platforms such as Umbraco and Xperience by Kentico
  • Delivering new functionality and enhancements for existing client platforms
  • Writing clean, maintainable and well-tested code
  • Taking part in code reviews and collaborative development
  • Working with CI/CD and modern development practices
  • Communicating with technical colleagues, project teams and clients
  • Contributing to technical discussions and continually improving your development skills

What We’re Looking For

We’re ideally looking for someone with:

  • Commercial software development experience within a .NET environment
  • Strong C# and .NET fundamentals
  • Experience with ASP.NET Core and Web APIs
  • Good SQL Server knowledge
  • Front-end experience with JavaScript and TypeScript
  • A genuine interest in full-stack development
  • Strong communication skills
  • A strong academic or educational background
  • A stable career history and an interest in developing within a business long term

Experience working for a digital agency would be particularly valuable.

Experience with Umbraco or Xperience by Kentico would also be a major advantage, although strong developers without this experience will still be considered.

React experience is useful but is not an essential requirement.

Why Apply?

You’ll be joining a long-established digital business with a strong reputation for delivering complex websites, applications and digital platforms.

The company offers exposure to a wide variety of clients and technical challenges, rather than working on the same product every day. There is also a strong emphasis on professional development, modern engineering practices and giving developers the opportunity to continue building their technical skills.

This could suit someone moving up from a junior position or an established mid-level developer looking for broader project exposure and the opportunity to strengthen their technical experience.

Package

  • Salary of £35,000 to £45,000
  • Permanent position
  • Hybrid working with 2 days per week in the Manchester office
  • Flexible office days
  • 37.5-hour working week
  • Core hours of 10:00am to 4:00pm
  • 25 days’ holiday plus public holidays
  • Your birthday off
  • Option to purchase additional holiday
  • Private healthcare
  • Gym subsidy
  • Railcard scheme
  • Pension with employer contribution
  • Enhanced maternity and paternity packages
  • Training and CPD opportunities
