I'm looking for a unicorn. Hiring a Senior DevRel fully focused on the Solana Ecosystem. Criteria: not only are you involved in important conversations in the Solana ecosystem, but you are seen by the community as a credible voice of reason We're professionals at @QuickNode. We have fun, but we're the adults in the room. We put quality at the top of our list, followed by speed. We were the first major RPC to support @solana and we continue to onboard more developers to the ecosystem than any other provider. Prefer you to be in US or EU where you can regularly work out of a Solana-focused coworking space, but can be flexible for an exceptional candidate. x.com/i/jobs/189014113617149…

If you are a builder I cannot recommend @QuickNode enough. It is ~3x as fast as every other provider out there. Your application and infrastructure don't have to be slow. Effects can be near instant.

Just played around with this and it's really smooth. Create a function and you get a REST API endpoint to call it with. No hosting, RPC calls, or deployments to figure out. Excited to see what some big brained QuickNode users do with functions 🧠 Endless possibilities!
