About the Role:
Cloud cost management is one of the biggest challenges organizations face today. As cloud adoption accelerates, complexity and spend rise with it—putting pressure on teams to prove efficiency and impact. CloudZero was built to meet that challenge.
CloudZero is a SaaS platform at the intersection of next-generation cloud cost management and FinOps. We ingest and organize billing and usage data across cloud, SaaS, and PaaS providers in real time, giving teams clear visibility at any level of time or resource granularity so they can make smarter business decisions.
As we scale, we’re looking to add a senior software engineer to our application platform team. Senior engineers are core to our success—helping define technical direction, translating strategic goals into executable work, and building high-quality software that delivers immediate value to customers.
What You’ll Do:
Design, build, and maintain APIs, services, and core systems that power CloudZero’s application platform.
Build scalable features that support customers with large, complex cloud cost datasets.
Work on the core product surfaces customers use every day, including cost intelligence features, analytics, and identity/authentication systems.
Partner closely with product managers, designers, and engineers to deeply understand customer problems and deliver high-impact solutions.
Participate in product discovery, helping break down strategic objectives into clear, executable work.
Write clean, testable, and maintainable code that can evolve as the product and company scale.
Help shape engineering processes and technical direction to enable fast iteration, ownership, and high-quality delivery.
What You Bring:
5+ years of experience building APIs and complex backend systems in the cloud (AWS preferred).
Strong proficiency in Python.
Hands-on experience with authentication and authorization systems (RBAC, SSO, SAML, OIDC, OAuth).
Experience working in early- or growth-stage B2B SaaS environments.
Familiarity with event-driven architectures and AWS serverless services (Lambda, API Gateway, DynamoDB, Step Functions, EventBridge, SQS).
Ability to apply sound design patterns pragmatically when architecting systems and writing code.
Comfort collaborating cross-functionally and translating feedback into polished, customer-facing solutions.
Please note: CloudZero is unable to sponsor employment visas. Candidates must have permanent authorization to work in the United States without the need for current or future sponsorship.

What We Do
CloudZero is the only cloud cost intelligence platform that puts engineering in control by connecting technical decisions to business results.
CloudZero ingests cost data from AWS and Snowflake, organizes it for analysis, and delivers the insights to engineering teams who can understand how their work is impacting the business.
You can answer question like:
* Who are my most expensive customers?
* Which product, feature, and team is spending the most?
* Has the profitability of my product changed quarter over quarter?
The outcome is real-time intelligence that helps companies control their cost of goods sold (COGS) and gross margins — aligning engineering and finance teams once and for all.
