How to Land Account Abstraction Jobs: ERC-4337, Bundlers, Paymasters, and Security Skills

I’ve been noticing a lot of buzz around Account Abstraction jobs, especially with ERC-4337 becoming more mainstream. I’m exploring opportunities in this space and wanted to ask the community: what exact skills are recruiters and teams looking for when hiring for account abstraction roles?

From what I’ve read, understanding bundlers and paymasters is critical, since they form the backbone of how ERC-4337 works in practice. But I’m wondering, do employers expect developers to already have hands-on experience building custom paymasters, or is strong Solidity knowledge enough to start with?

Another area that keeps coming up is security edge cases. Account abstraction changes how wallets interact with the network, so I imagine security audits and gas optimization strategies are highly valued. Has anyone here been through an interview or landed a role in this niche?

It would be super helpful if you could share what skills actually get you hired—whether it’s mastering ERC-4337 internals, writing efficient bundler code, or demonstrating real-world projects on GitHub.

Looking forward to hearing your thoughts and experiences!
