About the Role

We are seeking a talented and driven Full Stack Engineer to join our high-caliber team. You’ll collaborate directly with our CTO and other senior engineers to design and build both the frontend and backend components of our platform. Your work will span everything from crafting intuitive user experiences to developing scalable backend services and APIs that power our AI-driven analytics engine.

This is a great opportunity to work across the stack, own critical features end-to-end, and shape a platform that is redefining how organizations access insights from their data.

What You’ll Do

• Work across the stack to build, ship, and refine features that deliver value to users
• Build responsive, intuitive UIs using React.js and Next.js
• Connect frontend components to our backend APIs and services
• Write clean, maintainable code and contribute to team best practices
• Collaborate on product decisions, give feedback, and grow alongside experienced teammates

What We’re Looking For

• Bachelor’s degree in Computer Science, Information Technology, or a related field
• Strong understanding of JavaScript, including DOM manipulation and the JavaScript object model
• Experience with React.js or Next.js
• Familiarity with calling and working with RESTful APIs
• Comfortable using front-end tooling like Webpack, Babel, or NPM
• Exposure to backend development (e.g., working with databases or writing simple server-side code) is a plus, but not a dealbreaker
• Experience with Python is preferred
• Familiarity with cloud platforms (AWS, GCP, etc.) or DevOps concepts is a plus
• Interest in how AI/ML systems are built or used
• Eagerness to learn and grow in a collaborative startup environment
