Backend Engineer

About Pump.co

Gartner predicts that cloud spend will be over $2T/yr by 2030, making it the fastest-growing expense for tech companies. Managing it well demands constant engineering effort—time that could be spent building your product.

At Pump, we're building the fastest way to save ~60% on cloud costs. Our AI-powered platform not only automates savings but also leverages the power of group buying for even deeper discounts. Backed by Y Combinator, we’re on a mission to transform cloud cost optimization through AI.

Our founding team includes experienced entrepreneurs with prior exits, and our culture is fast-paced, collaborative, and flat in structure. If you’re excited about shipping real impact and joining a team at an early, career-defining stage—we’d love to meet you.
