Principal Software Engineer

Cloud cost management is one of the biggest challenges organizations face today. As cloud adoption continues to accelerate, so do the complexities and costs associated with it — and macroeconomic conditions only increase pressure to prove cloud efficiency. That’s why we built CloudZero: a SaaS platform at the intersection of next-generation cloud cost management and FinOps. CloudZero ingests billing and usage data from all cloud, SaaS, and PaaS providers, organizes it in real time according to our customers’ business structures, lets customers view it at any level of time or resource granularity, and ultimately empowers them to make more informed business decisions.

Since our founding in 2016, our mission has been to make efficient innovation a reality for every cloud-driven organization. At CloudZero, we believe every engineering decision is a buying decision, yet the cost conversation often bypasses the engineers who drive those determinations. To solve this, we’ve built a dynamic, single-page application that answers the complex, data-heavy questions every cloud-based organization needs to ask if they want to grow their company profitably.

To date, we’ve raised over $52 million from leading venture capital firms across the country. We’re solving problems of massive scale, business importance, and complexity in a space that needs it more than ever. We’re growing rapidly and would love for you to be a part of it!

As we continue to grow quickly, we’re looking to add a talented and experienced principal software engineer to a new product development team we are building out. This new team will ensure that the CloudZero platform is the leader in quickly bringing in cost and customer data. This team will become experts on how our customers use third-party SaaS and PaaS tools and build features on our platform to make it easy to bring their usage data in and combine it with our differentiated cost data model.

  • Help improve our engineering processes to ensure we have a team that can move fast and iterate quickly, giving everyone agency, ownership, and the ability to impact the broader success of the company


  • You have a passion for building and delivering high-quality software, and 12+ years of experience building APIs and complex backend systems in the cloud (AWS preferred)
