• Make key technical decisions around system design, architecture, tooling, cloud infrastructure, and AI model usage

• Improve performance, security, observability, scalability, and reliability across the platform
• Oversee cloud infrastructure across AWS, Azure, or GCP
• Guide engineers on best practices across code quality, architecture, testing, reviews, and delivery
• Help the team adopt AI-assisted development workflows to improve speed, quality, and productivity
• Work closely with the founder and product team to turn ideas into production-ready features quickly

• Strong backend experience with Python, ideally using Django, FastAPI, Flask, or similar
• Strong frontend experience with TypeScript and React or Angular
• Proven experience building and scaling APIs, backend services, and production-grade systems
• Experience with cloud platforms such as AWS, Azure, or GCP
