Lead Developer

Seeking a highly skilled Lead Developer to join the Software Delivery organization. This is not a traditional lead role—this position is designed for a hands‑on technical leader who excels in both strategic evaluation and practical implementation of software solutions, especially as the company continues to grow through acquisition.

The Lead Developer will play a critical role in assessing new tools and applications acquired through M&A activity, determining integration requirements, and either modernizing, retiring, or enhancing those systems. This is a unique opportunity to influence technology decisions, lead due diligence efforts, drive security compliance, and guide a team of developers while remaining deeply involved in day‑to‑day coding.

• Lead technical due diligence on applications acquired through organizational growth.
• Evaluate tools, technologies, and legacy systems to determine integration readiness and modernization needs.
• Enhance, retire, or refactor applications to align with enterprise architecture and security requirements.
• Strengthen overall security posture by applying modern security principles and hardening standards.
• Provide technical leadership and mentorship to a development team while remaining hands‑on with coding.
• Collaborate with stakeholders to identify risks, propose solutions, and guide technology decisions.
• Drive compliance initiatives to mitigate security vulnerabilities across applications.
• Deliver clear, polished, executive‑ready communication and recommendations.

• Strong experience with the .NET stack, including C#.
• Expertise in SQL Server and database design.
• Hands‑on experience with Azure cloud services.
• Full‑stack development experience with Angular (React acceptable).
• Experience modernizing legacy applications—migration, refactoring, hardening, or integration.
• Familiarity with security principles and application hardening.
• Financial industry experience preferred but not required.
