About the Role
We're looking for an exceptional Senior Software Engineer who lives at the intersection of engineering excellence and product obsession. You'll build backend systems behind our AI automation platform while being deeply involved in product decisions, customer conversations, and the "why" behind every feature.

🤩 Product Obsession: You ask "why?" relentlessly and dive into user behavior, business metrics, and customer feedback to understand real problems.
😄 Optimistic Collaboration: You make everyone more excited about building and help ideas get off the ground rather than die in committees.
😎 Authentic Communication: You build great relationships with non-engineers and learn how other disciplines work.
👷♂️ Craft Excellence: Joy comes from the craft itself. You love building products and continuously validate that your work creates real user value.

Curiosity about AI and automation solving real business problems
Product-Minded Traits
Deep interest in business models, user behavior, and success metrics
