Overview
Blockchain Engineer Jobs in Sharjah, UAE/Dubai at ATATREH ADNOTAM ELECTRONICS TRADING LLC
Responsibilities
Design, develop, and deploy a non‑custodial payment smart contract on EVM chains with funds routed directly wallet‑to‑wallet and an on‑chain fee mechanism. The contract must be immutable, publicly verifiable, and built with no custody or fund‑control functions.
Build and maintain the backend platform, including REST APIs, a merchant dashboard, real‑time transaction status, and webhook systems using Node.js and Type Script.
Integrate blockchain transaction screening and AML/KYC tools such as Chainalysis and Scorechain into the payment flow.
Implement multi‑chain and multi‑token support for BTC, ETH, USDT across TRC
20, ERC
20, BEP
20, Polygon, USDC, and other tokens.
Develop the point‑of‑sale software interface, including QR generation, rate‑lock logic, and gas abstraction for a smooth checkout.
Prepare the smart contract for independent third‑party audit and remediate findings before mainnet deployment.
Own security across the stack, including key management, secure architecture, and on‑chain verification.
Qualifications
- Proven, demonstrable smart contract experience in Solidity (Rust a plus). Must be able to share verified, deployed contract addresses on a block explorer and live Git Hub commit history; CVs alone will not be considered.
- Hands‑on experience building non‑custodial, wallet‑to‑wallet systems where the platform never takes custody of funds.
- Strong backend engineering in Node.js and Type Script, plus REST APIs, Postgre
SQL, and Redis.
- Experience integrating Web3 libraries (Ethers.js, Web
3.js) and development tooling (Hardhat, Foundry, Slither). - Understanding of crypto payment flows, gas optimization, and transaction finality.
- Bonus: experience with crypto payment gateways, exchange infrastructure, or UAE/VARA regulatory context.
Location
Based in or willing to relocate to the UAE (Dubai).
Assessment
A short live technical assessment will be part of the interview.
