Job description

Not Diamond is the leading intelligent AI optimization platform. We help AI/ML teams at leading startups and global enterprises automatically improve prompts, optimize agents, and intelligently route queries across the constantly evolving model landscape to rapidly drive quality improvements at the frontier. We improve workflow accuracy by as much as 50% or more and save the YC/Sequoia/a16z startups we work with an average of 160 engineering hours per month, with larger enterprises saving tens of thousands of engineering hours per year. We’re backed by Jeff Dean (Google), Julien Chaumond (Hugging Face), Ion Stoica (Anyscale, Databricks), Zack Kass (OpenAI), Olivier Pomel (Datadog), Akshay Kothari (Notion), Arash Ferdowsi (Dropbox), Tom Preston-Werner (Github), Guillermo Rauch (Vercel), Scott Belsky (Adobe), Jeff Weiner (LinkedIn), Eoghan McCabe (Intercom), and many more.

Why this role matters

We believe in a multi-model future. The world won't have one single, giant model that everyone sends everything to—instead, there will be hundreds of foundation models and billions of agentic systems running on top of them. We believe this is not only a better future for AI, but a safer one as well. But for this to happen requires massive infrastructure shifts that can enable us to better leverage the strengths of diverse models in a constantly evolving landscape. We started Not Diamond to enable this multi-model future.

In this role, you’ll work closely with our founding team to help define and execute our technical vision and contribute to a world-class research, engineering, and GTM organization. We want to work with immensely thoughtful, voraciously curious, and mission-driven contributors. You will play a pivotal role in driving forward GTM through technical sales, communicating sales insights back to inform product engineering decisions, helping support customer PoCs and other pre‑sales testing, supporting key account management post‑sales, and improving our technical sales processes. Ideally we’re looking to work with folks who have over 8 years of experience across technical sales and account management, with a focus in AI, ML, developer tools, and infrastructure.

We’re offering a competitive salary, generous equity, and robust benefits. And while we think of this as an opportunity to build a generational company from the ground‑up, we also guarantee an investment in your next startup if you ever decide to build something yourself in the future. Our team is guided by top‑percentile ambition, constant learning, and a bias towards action, and our focus on execution is rooted in a dedication to emotional intelligence, high integrity, and the ability to work through healthy conflict.
