.NET WEB DEVELOPER JOB DESCRIPTION

Legacy client-server systems don't migrate themselves, and enterprise portals don't stay reliable without someone who owns the code from API contract to rendered interface. That ownership belongs to the .NET Web Developer - a practitioner who holds both the front-end rendering layer and the back-end service contracts together within a single delivery commitment. Most of these roles operate inside Agile sprint cycles, accountable to development leads, account managers, and stakeholders who each have a different definition of "done." Object-oriented design discipline and RESTful API fluency are the baseline; judgment about what to refactor versus what to migrate is what separates the average from the effective.

As the .NET Web Developer, you own the design, implementation, and ongoing maintenance of enterprise web applications and RESTful APIs within a Microsoft-stack environment, from requirements analysis through production deployment. The position sits within a cross-functional engineering team, working alongside UI/UX designers, development leads, and account managers across concurrent sprint deliverables.

Career Impact: Sustained delivery experience across C#/.NET Core, MVC architecture, and modern frontend frameworks compounds into the kind of full-stack credibility that makes Senior Engineer and Architect-track conversations substantive rather than aspirational.

Business Impact: The client portals and migrated applications you build and maintain are the primary interface between the organization's products and its end users - degraded performance or delayed releases are immediately visible to customers and revenue.

Growth Opportunity: Exposure to cloud migration patterns, automated testing frameworks, and cross-team architecture reviews expands your scope toward technical lead and solution architect roles, where you define standards rather than implement them.

• Design and develop enterprise web applications and RESTful APIs using C#/.NET Core and MVC architecture patterns.
• Implement front-end interfaces from UI/UX wireframes across responsive web and mobile targets.
• Migrate client-server applications to web environments, maintaining documentation throughout each phase.
• Execute unit, integration, and functional testing before production deployment.
• Review and debug production defects, tracing issues from front-end symptoms to back-end root causes.
• Partner with development leads and account managers to refine requirements and provide effort estimates.
• Enforce code quality standards through peer code reviews and adherence to OOP design principles.
• Maintain and update technical documentation for new and existing application features.

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent work experience.
• 3 or more years of web application development experience, with demonstrated C#/.NET Core delivery in a production environment.
• Proficiency in object-oriented design principles, including dependency injection and established architectural patterns.
• Demonstrated ability to design, implement, and consume RESTful web APIs.
• Working knowledge of relational database design and query optimization using SQL.
• Experience with front-end development using HTML5, CSS3, JavaScript, and at least one modern JS framework.
• Familiarity with Agile/Scrum delivery practices and version control workflows.
• Clear written and verbal communication skills, with the ability to translate technical decisions for non-technical stakeholders.

• Experience with automated testing frameworks and test-driven development practices within a .NET environment.
• Exposure to cloud deployment environments such as Microsoft Azure or AWS, including serverless function patterns.
• Proficiency in TypeScript and component-based frontend architecture using Angular or React.
• Prior work on client portal development or legacy-to-web migration projects.

• Core Stack: C#, ASP.NET Core, MVC, Web API
• Frontend: Angular, React, TypeScript, JavaScript, HTML5, CSS3
• Backend & Data: SQL Server, Oracle, RESTful APIs
• Cloud & DevOps: Azure DevOps, Azure Functions, AWS, Git
• Testing & QA: Jest, unit testing frameworks, integration testing tools

• Base Salary Range: $95,000 – $135,000 annually, depending on experience and location.
• Bonus: Annual performance bonus, typically 5–10% of base salary.
• Equity: Not standard; offered at select product companies or pre-IPO environments.
• Health Benefits: Medical, dental, and vision coverage; employer contribution varies by company size.
• PTO: 15–20 days annually, plus standard federal holidays.
• Common Perks: Remote or hybrid flexibility, professional development budget, and conference attendance support.
