JOB DESCRIPTION 

We're looking for a highly experienced and dedicated Lead Full Stack Developer to take ownership of a custom suite of software developed in house. This is a key technical leadership position for an accomplished technologist who thrives on solving complex problems and guiding teams. You will lead a small, focused team of developers and a QA specialist, driving development across the full Microsoft stack and modern web technologies. 

JOB DETAILS 

Starting salary: $95K+ with comprehensive benefit package  

Regular onsite requirement (Must be local or willing to relocate)

EDUCATION AND EXPERIENCE: 

  • Minimum 10+ years of professional software development experience  

  • Minimum 5+ years of experience in a technical leadership capacity, with a proven track record of mentoring developers, reviewing code, and leading technical projects  

  • Core Programming (C# / OOP): Strong proficiency in C# is preferred, but we welcome applicants with deep expertise in equivalent Object-Oriented languages (e.g., Java, C++). If you understand strong typing, inheritance, and design patterns, we trust you can learn our stack. 

  • Frontend Frameworks (Angular): Experience with Angular is a plus, but we value proficiency in any modern component-based JavaScript framework (e.g., React, Vue, Svelte). We are looking for developers who understand state management, component lifecycles, and responsive design, regardless of the specific library. 

  • ERP & Business Systems (JDE): Exposure to any Enterprise Resource Planning (ERP) system or complex business logic is a plus but not requirement.  Job requires minimal interaction with ERP. 

  • Database Design & SQL: Proficiency in relational database design and SQL development is required. You must be capable of designing efficient schemas, writing complex queries, and utilizing ORM tools to build performant data-driven applications. 

  • Problem Solving: A track record of writing clean, maintainable, and testable code. We value engineering fundamentals and the ability to adapt to new tools over rote memorization of specific syntax. 

RESPONSIBILITIES 

  • Technical Leadership: Serve as the technical authority and primary hands-on developer, setting a high standard for code quality and ensuring the team’s output aligns with architectural best practices. 

  • Mentorship & Code Quality: Lead code reviews and provide day-to-day mentorship to junior and mid-level developers, fostering their technical growth and ensuring the delivery of maintainable, high-quality code. 

  • Front-End Development: Lead the design and implementation of responsive user interfaces using Angular, TypeScript, JavaScript, and HTML. 

  • Back-End Development: Navigate and develop complex server-side logic in C#, including API endpoints and traditional MVC controllers attached to views. Develop and maintain the C# Business Logic Layer (BLL) and the Data Access Layer (DAL), utilizing Entity Framework as the ORM. 

  • Database Management: Expertly manage and optimize data interactions within our Microsoft TSQL environment across various SQL databases. 

  • Feature Integration: Collaborate on and contribute to the development of application features that include graphical aspects, utilizing web technologies such as Canvas. 

  • Systems Integration: Develop and maintain C# middleware and backend services responsible for integrating application data with our ERP system and JD Edwards. 

  • Architecture & Standards: Define the technical vision and enforce development best practices across the team. 

  • Workflow Management: Lead the team's Agile (Scrum-ban) process, driving ticket tracking using Jira, facilitating planning, and removing technical blockers to ensure smooth workflow. 

  • Cross-Functional Collaboration: Serve as the key technical liaison within a larger cross-functional group, including the Product Owner and Marketing team, translating business needs into technical requirements.

Your decision to complete the form and your answer will not harm you in any way.
