Senior Sitefinity (.NET) Developer – Driving Excellence in Enterprise Web Development

At Construct Digital, we've grown to become the leading Results-Driven B2B Digital Agency, where strategic thinking, compelling ideas, and smart technology converge to create impactful solutions that drive business growth. Our unique B2Human approach goes beyond logic and reason, tapping into emotions to drive decisions and forge lasting connections.

With a suite of services spanning Consulting, Marketing, Media, Technology, Strategy, and Creative, we're dedicated to delivering measurable results through a blend of creativity, technology, and data-driven strategies.

Your Role:

We are seeking a Senior Developer with proven, hands-on Sitefinity expertise to design, build, and maintain enterprise-level websites. This is a remote position, open to candidates based in the APAC region or nearby time zones. Please note that this role specifically requires Sitefinity CMS experience — it is not a general .NET developer position.

You will be responsible for designing and implementing scalable, high-performing web solutions while working closely with Technical Architects, Front-end Developers, and Project Managers. You will also help define technical strategies, manage deployments, and ensure our solutions are optimised for performance and future scalability.

Key Responsibilities:

Design, develop, and maintain enterprise-level websites using Sitefinity CMS

Implement and maintain .NET-based web applications and APIs

Customise Sitefinity components and integrate third-party systems or APIs

Optimise performance, scalability, and deployment pipelines

Write clean, maintainable, and secure code following best practices

Provide technical troubleshooting and production support for Sitefinity projects

Collaborate with Technical Architects, Front-end Developers, and Project Managers

Maintain clear technical documentation and contribute to process improvements

What We Look For:

Minimum 4 years of hands-on Sitefinity CMS development experience (mandatory)

Strong proficiency in .NET Framework, including ASP.NET MVC, Web API, and .NET Core

Proven experience in customising Sitefinity widgets, modules, and integrations

Solid knowledge of SQL Server and database design

Strong understanding of front-end technologies (HTML, CSS, JavaScript, jQuery)

Experience with Azure (preferred) or AWS cloud environments

Strong debugging, problem-solving, and analytical skills

Excellent communication and collaboration skills in a remote team setup

Familiarity with SEO-friendly web development

Sitefinity Developer Certification is an advantage

Hands-on experience using AI-assisted development tools (e.g., GitHub Copilot, Cursor.ai, ChatGPT, or similar) to improve coding efficiency and documentation

Receive a competitive salary, performance bonuses, and top-tier equipment to help you do your best work.
