Contribute to UX and product design discussions, including features, flows, and epics
Help evolve the platform’s AI capabilities over time

Hands-on skills in fullstack or backend development and modern cloud-based platforms
Experience with rapid prototyping and making architectural decisions in ambiguous environments
A passion for writing scalable, maintainable code and continuously improving it over time
Solid understanding of API design, platform integration patterns, and backend systems
A collaborative, pragmatic mindset — you thrive in small teams and take ownership of your domain
