## Description

The Development Team Lead (.NET) is responsible for providing hands-on technical leadership, mentoring, and delivery oversight for a team building enterprise applications on the Microsoft .NET platform.

This role blends deep .NET expertise with people leadership, Agile delivery, and cross-functional collaboration.

**Key Responsibilities**

**Technical Leadership**

- Lead the design and development of applications using C#, VB.NET, ASP.NET Core, ASP.NET MVC, Web API, LINQ, and related .NET technologies.

- Guide modernization of legacy VB.NET, WCF, and .NET Framework applications and services into modern C#, ASP.NET Core, and .NET 8+ API architectures.

- Define and lead migration strategies for legacy WCF/SOAP services, including service decomposition, API design, security modernization, backward compatibility, and transition to RESTful and event-driven architectures.

- Provide technical leadership for both the ongoing enhancement of existing WCF-based applications and the strategic modernization of those platforms to ASP.NET Core and cloud-ready architectures.

- Evaluate and implement modern integration patterns using REST APIs, microservices, Azure Service Bus, and cloud-native services as part of application modernization initiatives.

- Perform and enforce high-quality code reviews, ensuring adherence to coding standards, clean architecture, and SOLID principles.

- Break down complex technical requirements into well-scoped stories and tasks.

- Work with Architects to align on technical patterns, integration approaches, and long-term platform direction.

**People Leadership & Coaching**

- Provide day-to-day support, mentorship, and coaching to developers across varying experience levels.

- Foster a positive, inclusive culture centered on learning, ownership, and accountability.

- Conduct regular 1:1s and support career development, skills progression, and performance management.

**Agile Delivery & Planning**

- Lead sprint planning, backlog readiness, estimation, and throughput optimization.

- Facilitate daily stand-ups, reviews, and retrospectives; remove team impediments rapidly.

- Coordinate dependencies with QA, DevOps, and other teams; ensure release readiness and change control.

- Partner with the Delivery Manager (or act in that capacity where needed) to maintain predictable sprint throughput and reliable release timelines.

**Quality & Reliability**

- Ensure strong testing practices: unit testing (xUnit/NUnit/MSTest), integration testing, API testing, and automation support and high code coverage targets.

- Collaborate with QA to embed quality in the workflow; drive shift-left testing practices.

- Validate that applications meet non-functional requirements such as performance, resilience, and security.

- Collaborate with DevOps to improve CI/CD pipelines, environment stability, and release automation.

**System & Application Ownership**

- Provide technical leadership for legacy service modernization initiatives, including assessment, refactoring, migration planning, risk management, and production rollout of WCF-to-.NET Core API transformations.

- Troubleshoot and resolve complex issues across environments (DEV/QA/UAT/PROD).

- Lead root cause analysis for production incidents and identify long-term fixes.

- Monitor application health using Application Insights, logging frameworks, and dashboards.

**Cross-Functional Collaboration**

- Partner with Product Owners to refine user stories, clarify requirements, and provide estimates.

- Work closely with DevOps for CI/CD enhancements and infrastructure needs (Azure preferred).

- Collaborate with QA Lead, Architecture, and Security teams to ensure compliance with standards.

**Qualifications**

**Required**

- 8+ years of professional software development experience with .NET Framework, .NET Core, and enterprise application development.

- 2+ years in a people leader role.

- Strong expertise in C#, with hands-on experience developing, enhancing, supporting, and modernizing applications built on VB.NET, WCF, and the .NET Framework.

- Hands-on experience designing, developing, supporting, and modernizing WCF/SOAP services, including execution of WCF-to-ASP.NET Core Web API migration initiatives, service contract analysis, authentication modernization, API versioning, and integration modernization.

- Strong understanding of enterprise integration patterns, including SOAP, REST, messaging, service-oriented architecture (SOA), and microservices.

- Experience maintaining and enhancing enterprise applications built on WCF, SOAP, and .NET Framework, including troubleshooting, performance tuning, and delivery of new business functionality.

- Experience building REST APIs, microservices, or modular applications using ASP.NET Core/Web API.

- Proficiency with Git, CI/CD pipelines (Azure DevOps/GitHub Actions), unit testing frameworks, and design patterns.

- Experience working in Agile environments (Scrum/Kanban) with strong facilitation skills.

- Demonstrated ability to lead teams, influence architecture, and deliver complex initiatives.

- Excellent communication, facilitation, and problem-solving skills.
