Today, our products support more than 85,000 organizations, millions of volunteers, and over 600 million volunteer hours across the nonprofit, public, healthcare, and corporate sectors. Our vision is a world where volunteerism is recognized, resourced, and respected in every community. We are a growing, private-equity-backed business, and we focus on work that matters. ABOUT THE ROLE We're looking for a senior full stack engineer with strong architectural sensibilities to take ownership of our global platform services. These are the foundational systems that sit beneath every product we build: single sign-on, control plane, and data plane services including the aggregation layer and data hub infrastructure.

You are here to own the layer that everything else depends on. This is a high-leverage role. The services you own are consumed by every product in our portfolio, so your decisions have outsized impact on reliability, developer experience, and our ability to scale. WHAT YOU'LL DO Own core platform services: Design, build, and maintain SSO and auth services, profile services, and data aggregation layers that serve as the backbone for all products Build across the stack: Write backend APIs and services, then build the frontend interfaces that consume them Drive architectural decisions: Evaluate trade-offs, document decisions, and guide the evolution of our service architecture Build for scale and reliability: Design systems that handle growth gracefully with appropriate observability, error handling, and recovery patterns Build for a multi-region footprint: Make sound decisions about data residency and data movement across the US, Canada, the UK, and Australia Ship production code: This isn't a whiteboard-only role. You'll write code daily and own features end to end Collaborate across teams: Work with product engineers who consume your services to understand their needs and provide clean, well-documented APIs 7+ years of professional software engineering experience Strong full stack capabilities.
