Job description

About the Role
CloudZero is redefining FinOps with AI-powered experiences that help organizations understand and optimize their cloud spend. We’re looking for a Fullstack Engineer to join our Research Team and take ownership of advisor.cloudzero.com—our intelligent lead generation platform.

This role is perfect for a hands-on engineer who thrives on autonomy, fast iteration, and solving meaningful user problems. You’ll lead development of highly interactive, AI-driven systems that shape how users discover and engage with CloudZero from the very first click.

What You’ll Do

• Lead fullstack development of advisor.cloudzero.com.

• Build modern, performant UIs with React, Vite, Astro, and Tailwind.

• Develop backend services using Python (FastAPI or similar) to support AI workflows and lead routing.

• Integrate AI/LLM APIs and design personalized user experiences using retrieval-augmented techniques.

• Work natively in AWS (Lambda, DynamoDB, S3, API Gateway, EventBridge).

• Collaborate across product, marketing, and research to iterate quickly and deliver value.

• Prototype and evaluate emerging AI tools (e.g., RAG, Bedrock, vector search).

What We’re Looking For

• Strong fullstack experience with modern frontend frameworks and Python backends.

• Hands-on experience integrating AI/LLM features into production systems.

• Deep familiarity with AWS serverless tools.

• Strong product sense, UX intuition, and understanding of conversion funnels.

• Proven ability to self-direct and ship meaningful features with minimal oversight.

• Effective communicator across technical and non-technical teams.

Bonus Points

• Experience with LangChain, CrewAI, or AWS Bedrock Agents.

• Familiarity with A/B testing, analytics, and behavior tracking.

• Background in DevTools, marketing tech, or developer experience.

• Exposure to FinOps or cloud infrastructure (optional).

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 millionfrom 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!
