Sr. Software Developer

Role

Senior Software Developer responsible for designing, building, and modernizing mission-critical web applications and backend services using the Microsoft stack. The role is hands-on: own technical design, write production code, mentor junior/mid engineers, and collaborate with product owners and business stakeholders to move legacy systems to a cloud-first architecture.

Key Responsibilities

• Design, develop, and maintain backend services and RESTful APIs using C#, .NET (Core/6/8), and ASP.NET Core running in Azure.
• Build and maintain rich, responsive front-end applications using Angular (v15+; currently Angular 19) and contribute to React-based components as needed.
• Integrate front-end and back-end systems to deliver secure, reliable, and performant web applications.
• Implement cloud-native solutions using Azure services (App Service, Azure Functions, Durable Functions, storage, and related PaaS offerings).
• Design and optimize relational data models, queries, and stored procedures in SQL Server; integrate with Oracle where required.
• Gradually modernize legacy applications (Classic ASP, older .NET apps, Sitefinity 13/15) as part of transformation efforts.
• Use AI coding assistants in a “vibe coding” style for rapid prototyping and boilerplate generation, while thoroughly reviewing, testing, and understanding generated code.
• Contribute to application and solution architecture, selecting patterns and approaches that balance reliability and delivery speed.
• Implement automated tests (unit, integration, end-to-end) and improve test coverage.
• Perform code reviews, enforce engineering standards, and apply secure SDLC practices.
• Collaborate with product owners, business analysts, security, infrastructure, and operations to refine requirements and deliver solutions.
• Use Azure DevOps and GitHub for source control, branching, pull requests, and CI/CD pipelines.
• Troubleshoot production issues, improve observability (logging, metrics, dashboards), and drive root-cause analysis.
• Mentor mid-level and junior engineers and contribute to technical documentation and internal wikis.

Requirements

• 6+ years of professional software engineering experience building production web applications.
• Strong proficiency in C# and .NET (Core/5/6/7/8) including experience building RESTful APIs and backend services.
• Hands-on experience with modern front-end frameworks, preferably Angular (v10+); exposure to React is a plus.
• Practical experience deploying and running applications in Azure (App Service, Azure Functions, storage, configuration, identity).
• Solid understanding of relational databases (SQL Server required; Oracle is a plus) including schema design and query optimization.
• Experience with Git-based workflows and CI/CD pipelines using Azure DevOps or similar (e.g., GitHub Actions).
• Working knowledge of secure coding practices (authentication/authorization, secrets protection, input validation, OWASP Top 10 concepts).
• Strong communication skills and ability to translate loosely defined business problems into technical designs.
• Bachelor’s degree in Computer Science, Engineering, or related field, or equivalent experience.

Preferred Qualifications

• Experience in public sector, transportation, or other mission-critical operational environments.
• Experience migrating and modernizing legacy web applications (Classic ASP, older ASP.NET Web Forms or MVC).
• Sitefinity or other .NET-based CMS experience (authoring, customization, integration).
• Experience with Azure Durable Functions, event-driven architectures, and distributed systems patterns.
• Familiarity integrating with enterprise systems such as Workday or ServiceNow.
• Experience with chatbots, search, or AI-assisted workflows (Azure AI Search, Azure OpenAI, etc.).
• Experience with Application Insights or similar monitoring platforms.
• Comfortable using AI assistants like GitHub Copilot or ChatGPT to accelerate development while maintaining quality.
• Prior experience mentoring engineers, acting as a tech lead, or owning systems end-to-end.

Logistics

• Work arrangement: 100% onsite / In person.
• Interview: Onsite.
• Job types: Full-time, Contract.
• Expected hours: 40 per week.
• Pay: $50.00 - $65.00 per hour.
