Senior Fullstack Engineer at Member Solutions developing and modernizing software for membership management. Collaborate with cross-functional teams while leveraging AI and building scalable systems.
Responsibilities
You’ll be responsible for building new functionality while modernizing the core software that powers our business.
Expect to work across a mixed landscape of .NET and Java applications—some modern, others dating back 20+ years.
This isn’t just about fixing bugs or shipping short-term features.
You’ll help define how we rebuild and consolidate systems, leverage AI to speed up delivery, and make architectural decisions with long-term business impact.
You’ll work closely with engineers, product managers, and stakeholders across departments to prioritize the right work and see it through.
You’ll need to be hands-on with code while also stepping back to guide long-term strategy.
This role requires someone who can operate with minimal direction, move between big-picture planning and day-to-day execution, and consistently deliver real business value.
