Build backend services, APIs, and frontend systems that power a real-time collaborative content platform

Contribute meaningfully to architectural decisions — your opinion matters and will be sought

Integrate AI tooling concretely into your development workflow and into the product

5–8 years of professional software engineering experience

Genuine full-stack capability — you have shipped production systems on both backend (APIs, cloud infrastructure, data services) and frontend (component systems, browser performance, interactive UIs)

Strong API design experience: REST, GraphQL, and webhooks — with opinions about when to use each

Cloud-native fluency: you have designed and operated services in GCP, AWS, or Azure, not just deployed to them

Experience with real-time or collaborative systems is a meaningful plus — live data sync, multiplayer state, event-driven architectures

Frontend architecture depth: component modeling, state management, rendering performance

Bachelor's degree in Computer Science or equivalent practical experience

You are actively and concretely building with AI — integrating it into products you own or creating tooling that makes AI more effective.
