Software Engineer (DevNull)

About the Role:
CloudZero is the leading cloud cost intelligence platform, helping engineering teams understand and optimize their cloud spend. We’re looking for a Software Engineer to join our Insights team—responsible for surfacing cost-saving opportunities, identifying spend anomalies, and delivering meaningful analytics to customers building in the cloud.

If you’re passionate about solving complex data problems, building user-focused backend systems, and making a measurable impact at scale, this role is for you.

Ready to help engineers save money and build smarter in the cloud?

What You’ll Do

• Design, build, and maintain scalable APIs, services, and backend systems.

• Write clean, maintainable Python code that’s easy to extend and iterate on.

• Collaborate with engineers, product managers, and designers to build features that solve real customer problems.

• Contribute to improving our engineering systems and workflows to support fast iteration and team ownership.

• Scale our platform to support larger datasets and growing enterprise customers.

Our Tech Stack

We leverage modern serverless technologies to power a real-time, event-driven architecture:

• AWS Lambda, Step Functions, S3, EventBridge.

• Snowflake for large-scale data processing.

• Python as our primary backend language.

• Kanban workflow and small, cross-functional teams.

You May Be a Great Fit If You

• Have experience building and maintaining APIs and backend systems in cloud environments (AWS preferred).

• Enjoy working with large datasets and solving data-centric engineering challenges.

• Are fluent in Python and take pride in writing high-quality, scalable software.

• Understand and apply system design principles pragmatically.

• Value cross-functional collaboration and turning feedback into well-crafted solutions.

• Are open to a hybrid schedule and able to work from our Boston Collaboration Center once per week.

About CloudZero:
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!
