The Role

We are seeking a Principal Software Engineer to serve as both a hands-on technical leader and the primary architect of core systems. This role is ideal for a player-coach who thrives in smaller teams, takes full ownership of technical architecture, and is capable of driving modernization across legacy and modern platforms. This individual will act as the complete system owner, responsible for on-premises and hybrid cloud environments, databases, networking, and application architecture.

What Youll Do

• Lead modernization of a legacy .NET v4 platform toward .NET 8 while ensuring stability of current systems.
• Own architecture for applications, infrastructure, databases, and networking across on-premises and Azure hybrid environments.
• Provide hands-on development (C#, .NET, EF, T-SQL) while also guiding technical direction, performing code reviews, and setting standards.
• Define and implement strategies for scaling, security, and reliability of systems and data.
• Collaborate with a fractional product manager to refine requirements and align technical solutions with business goals.
• Mentor engineers, establish best practices, and ensure adherence to modern engineering principles.
• Troubleshoot and resolve issues across networking, servers, and data systems.
• Partner with DevOps to guide CI / CD, QA, and automation standards (though not responsible for building pipelines directly).
