• Technical leadership and mentoring. You will guide offshore developers and contractors from a technical perspective, providing mentorship, coaching, and best practices. You will collaborate with senior developers and the Technical Lead to solve complex problems and design effective solutions.
• Collaboration and problem-solving. You will translate business requirements into practical solutions, review API documentation, and implement features according to product team priorities. You will actively participate in team meetings, code reviews, and design discussions to ensure alignment and continuous improvement.
• Knowledge sharing and process improvement. You will document processes, share lessons learned, and provide feedback on workflow enhancements. You will support a culture of continuous learning and knowledge exchange across the development team.

Here’s what you bring:

• The technical expertise. You have in depth software development experience, working with C#, HTML, JavaScript, and Microsoft SQL Server. Familiarity with ASP.NET Web Forms is a plus. You have experience with DevOps practices, testing, and maintaining code quality. You are comfortable learning new tools, APIs, and frameworks. You can create efficient, scalable solutions, troubleshoot complex technical issues, and contribute to system architecture.
• The flexibility. You are available to work from 9:00 a.m. to 5:00 p.m. Eastern Time to collaborate effectively with your team and ensure timely delivery of projects.
• The drive. You are eager to learn, curious, and proactive. You quickly come up to speed on new releases, tools, and technologies, including APIs, automated workflows, and emerging platforms.

• The solution focus. You are analytical, detail-oriented, and client-focused with strong problem-solving, critical thinking, and organizational skills. You identify patterns, reference prior resolutions, and build upon existing documentation to deliver effective and reliable solutions.
• The leadership. You provide technical guidance and mentorship to offshore developers and contractors, ensuring high-quality delivery. You coach team members, foster collaboration, build trust across teams, and support professional growth. You work closely with senior developers to drive best practices, contribute to system design, and achieve team objectives.
• The interpersonal skills. You possess excellent verbal and written communication skills, enabling you to build relationships and earn trust with ease.

You are a collaborative team member in a virtual environment, responsive, exercise sound judgment, and show respect for differing perspectives.
