- Own stack reliability: node ops, RPC tuning, indexing, monitoring, alerting, and incident response.
Requirements
- Expert Golang in Cosmos/Tendermint; mastery of state machines and consensus.
- Deep Evmos EVM proficiency: precompiles, opcodes/gas, JSON-RPC, cross-compat.
- Hands-on with Greenfield SDKs/APIs, ACLs, and chain/contract integration patterns.
