Senior Software Engineer (Full Stack) - Donor Intelligence

Virtuous provides software that helps nonprofits connect with and inspire their donors. The Senior Software Engineer (Full Stack) will build, scale, and maintain reliable web applications across the frontend and backend, while delivering new features and improving performance, scalability, and observability. The role also involves collaborating cross-functionally and contributing to architectural and technical decisions.

Responsibilities

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 continuous delivery
