• Closely collaborate with the founders – you decide on architecture, tools, frameworks, and set technical standards (clean code, testing, code reviews, DevOps processes)

Requirements

• Deep experience with backend systems, infrastructure, and API design
• Thrives in early‑stage environments where speed and adaptability are key
• Enjoys solving complex technical challenges with an eye toward scalability and maintainability
