Position Summary We're looking for a Senior Software Engineer (Full Stack) to join our growing Engineering team. This role will report directly to Engineering leadership and collaborate cross-functionally with stakeholders across Product, Design and Engineering. You'll help us build, scale, and maintain the web applications that power the Virtuous platform - keeping them fast, reliable, and observable as our traffic and data grow, while also shipping the net-new features that win deals and deepen the value customers get from the product. You should feel comfortable across the full stack, from crafting intuitive UIs to designing robust backend services, but gravitate toward the harder questions: How does this behave under load? Where does it fall over, and how do we know before our customers do? How do we ship quickly without sacrificing reliability? It's essential that you already know and actively use modern AI development tools and that you're curious about how to make them work harder for you. We treat AI agents as a core part of how strong engineers work today: a force multiplier across the entire stack. But we never trade speed for quality. You stay firmly in the driver's seat, owning the correctness, design, and long-term health of everything you ship, and bringing the judgment to know when to lean on a tool, when to question it, and when a hard problem still demands your own thinking. Our current tech stack is Python/Django on the backend, with PostgreSQL as our primary datastore. On the frontend, we're actively migrating from React/GraphQL toward a leaner, server-side architecture built on HTMX. We're continually evaluating tools and frameworks to support a growing platform, and a willingness to explore new technologies and offer thoughtful input into technical and infrastructure decisions is important to us.

Responsibilities

• You'll own meaningful, high-impact areas of the platform end to end - not just contribute to them. Specifically, you can expect to:
• Own the performance and scalability of our data layer as we onboard larger and more complex organizations - indexing, query optimization, read replicas, partitioning, and connection pooling - so onboarding and day-to-day usage stay fast and reliable even at enterprise scale
• Own our asynchronous and background-processing infrastructure (e.g., Celery), keeping it healthy, observable, and able to keep pace with growing data volume
• Design, build, and ship net-new, revenue-driving features across the full stack - from messaging and bulk-sending capabilities to richer reporting, analytics, and email experiences
• Help reinforce and extend our move to a server-side, HTMX-based frontend, improving both developer velocity and front-end reliability
• Design, build, and maintain scalable web applications used by nonprofit organizations around the world
• Collaborate closely with cross-functional teams to understand user needs and translate them into technical solutions
• Write clean, testable, and efficient code across the frontend and backend
• Contribute to architectural discussions and help drive technical decision-making across the platform
• Participate in code reviews, and help foster a culture of learning and improvement
• Own the reliability, performance, and observability of the systems you work on - instrument them well, set meaningful alerts, and treat production health as a first-class part of the work
• Provide thoughtful feedback on technology choices as we evaluate changes across our stack
• Support a culture of experimentation, iteration, and contin
