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 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
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
You Must Have
6+ years building modern web applications, including meaningful time spent running and scaling them in production
Proficiency in Python and frameworks like Django (or similar)
Hands‑on experience with AI coding agents (Claude Code, Cursor, Copilot, etc.) as part of your regular development workflow
Experience operating cloud infrastructure (AWS, GCP, or Azure) and infrastructure‑as‑code tooling (e.g., Terraform)
Experience with JavaScript/TypeScript and frontend frameworks such as React or Vue
Strong understanding of relational databases such as PostgreSQL — not just querying them, but tuning them: indexing, query optimization, and strategies for scaling (read replicas, partitioning, connection pooling, etc.)
Experience integrating with RESTful and/or GraphQL APIs
Solid DevOps fundamentals: CI/CD pipelines, containerization, infrastructure monitoring, and hands‑on experience scaling applications under real load
Comfort with observability tooling (metrics, logging, tracing, alerting) and a habit of using it to debug and prevent production issues
A love for building quality products that delight users and solve real problems
Strong communication skills and a team‑first mindset
Nice to Haves
Familiarity with container orchestration (Kubernetes) or modern PaaS deployment
Experience defining and working against SLOs/SLIs, or otherwise formalizing reliability targets
Experience working in a SaaS or B2B product company
Familiarity with C# / .NET
Prior experience in the nonprofit tech space
Contributions to open‑source projects or relevant technical blogs
Excitement about helping teams grow and mature their engineering practices
