Sr. Software Engineer, GenAI

Instrumentl is a hypergrowth YC-backed startup with over 4,000 nonprofit clients, from local homeless shelters to larger organizations like the San Diego Zoo and the University of Alaska. We are building the future of fundraising automation, helping nonprofits to discover, track, and manage grants efficiently through our SaaS platform.

Our charts are dramatically up-and-to-the-right 📈 — we’re cash flow positive and doubling year-over-year, with customers who love us (NPS is 65+ and Ellis PMF survey is 60+). Join us on this rocket ship to Mars!

As a Sr. Software Engineer, GenAI at Instrumentl, you’ll own the full lifecycle of AI features—from rapid prototyping to production deployment and ongoing evaluation. You will build agentic LLM systems that can plan and use tools, implement RAG pipelines over our domain data, manage and evolve embeddings and indices, and stand up evaluation/observability so our AI is grounded, safe, and cost‑effective.

Our ideal candidate is a strong software engineer, has experience building AI features and most importantly eager to learn, willing to experiment, and excited to empower both teammates and customers to accelerate social progress and propel innovation.

You’ll embed with one of the above groups in a hands-on role, collaborating closely with Product and Design, while partnering with DTI on platform‑level AI capabilities.

The Instrumentl team is fully distributed (though if you’d like to work from our Oakland office, we would love to see you there). For this position, we are looking for candidates based in the United States who have significant overlap with Pacific Time Zone working hours.
