Job Description

We are hiring for one of our clients. They are a fast-growing Web3 startup rethinking how digital identity and reputation work online. They’re building privacy-first infrastructure that lets users prove who they are and what they’ve done—without giving up personal data. Backed by strong ecosystem partners and a passionate founding team, the company is shaping a more trusted and user-centric internet.

We are looking for a Protocol Engineer to design, implement, and operate the core software of a L1 Chain—focusing on reliability, performance, and the identity‑specific features.

• Engineer EVM-compatible capabilities on Evmos—precompiles, fee markets, state logic, and cross-layer behaviors.

• Implement and run BNB Greenfield storage integrations: permissions, cross-chain flows, and app-level patterns.

• Manage chain upgrades, hotfixes, and param changes via governance, migrations, and multi-env execution.

• 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.

• Strong in Docker/K8s, CI/CD, IaC for chain infra; plus node ops (pruning, sync, RPC).

• Rigorous testing (simulations, property-based, upgrade rehearsals) and observability (Prom/Grafana, traces, playbooks).
