Front-End .NET Developer

As a Senior Software Engineer, you will play a key role in driving the technical strategy, development, and upkeep of Quill’s core applications and system integrations. You’ll be responsible for crafting and enhancing software components - including programs, scripts, and data models - based on detailed design specifications that emphasize performance, reliability, and scalability.

We are looking for a highly skilled Front-End .NET Developer with 4–7 years of hands-on experience in building responsive, user-friendly web interfaces. The ideal candidate must be strong in HTML, CSS, Bootstrap, JavaScript, and experienced in integrating front-end components with .NET MVC and C# backend logic. Hands-on experience with MS SQL, Figma, and Photoshop for UI interpretation and asset preparation is required.

This role requires deep expertise in system integration, testing, and technical documentation, with a strong focus on designing intuitive, customer-facing front-end applications throughout the Software Development Life Cycle (SDLC). You’ll write clean, efficient code, build tools and applications, and contribute to initiatives that impact your team’s deliverables.

You’ll bring a thorough understanding of the organization’s software ecosystem, with advanced proficiency in .NET technologies and key programming languages such as C#, SQL, and JavaScript. Assignments typically span short to mid-term durations and require independent decision-making, though work is reviewed at defined checkpoints.
