About the role
- We're hiring a Senior Backend Engineer to own AI features end to end, from rapid prototype to production and the evaluation that keeps them honest.
- You'll build the APIs, tool-using agents, and RAG pipelines that turn frontier LLMs into grant discovery, application drafting, and research tools our 5,500+ nonprofits rely on every day.
- It's a high-ownership seat on a small team, where what you ship reaches customers fast and you help shape how we build AI here.
Responsibilities
- Build tool-using LLM agents (task planning, function and tool calling, multi-step workflows, guardrails) for grant discovery, application drafting, and research assistance.
- Build trustworthy backends
- Collaborate and raise the bar
- Partner with Product, Design, and GTM on scoping, UX, and measurement.
- 7+ years building and shipping production backend systems in Python (FastAPI, Celery, or equivalent), taking features from prototype to production with real reliability practices like tests, observability, and rollback.
Nice to have
- TypeScript and Node, plus familiarity with Ruby on Rails (our core platform) or a willingness to learn it.
- Experience with AWS or GCP, Docker, CI/CD, and observability (logs, metrics, traces).
- Evaluation mindset: designing eval suites (RAG/QA, extraction, summarization) using automated and human-in-the-loop methods, with familiarity with frameworks like Ragas, DeepEval, or OpenAI Evals.
- Orchestration frameworks: LangChain or LangGraph, LlamaIndex, Semantic Kernel, or custom orchestration.
- We're committed to paying competitively and equitably.
- For candidates based in Canada, compensation varies by province and will be shared by your recruiter early in the process.
