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.

Responsibilities

• Drive full lifecycle of Cosmos SDK/Tendermint modules: build, customize, and maintain with deep consensus/networking impact.
• 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.
• 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).
