A fast-moving Web3 product team is hiring a Mid-Level Backend Engineer with real EVM/Web3 production experience. We build and run wallet and on-chain services used by high-traffic crypto apps, and you’ll ship APIs that talk to Ethereum and L2s every day. This is a remote, full-time role. Core collaboration happens on Eastern Time (ET), but we’re flexible for the right candidate.

What you’ll do

Build/own services in Node.js/TypeScript or Go.
Send txs, manage nonces/gas, handle reorgs; keep flows idempotent.
Index on-chain events and keep data in sync (Postgres, Redis).
Design clean REST/gRPC with auth, rate limits, retries.
Add metrics/alerts, write tests, keep CI/CD green; light on-call.

Must-have

3–5 yrs backend, incl. 1–2+ yrs EVM/Web3 in prod.
Strong in Node/TS or Go; solid SQL.
Hands-on with RPC (HTTP/WS), tx lifecycle, event subs.
You write tests by default and can show an incident you fixed—cause → fix → prevention.
Clear written English.

Nice-to-haves

Can read Solidity; L2 exposure (OP/Arbitrum/Base/zk).
Basics of key management (KMS/HSM) and perf tuning.

Recruiting Flow

1. Application Review – We scan your CV/LinkedIn, GitHub/code samples, and real Web3 production work (tx lifecycle, RPC, indexers).

2. Intro Call (20–30 min) – Quick background chat: what you’ve shipped, stack fit, salary range, and ET overlap.

3. Practical Task – Small backend exercise (e.g., a minimal tx submitter or log indexer) with tests, logging, and a short README. Time-boxed.

4. Technical Interview (60–90 min) – System design + code walkthrough + live debugging (nonces, reorgs, idempotency).

5. Offer – If it’s a match, we move fast.
