Hanoi Capital Region, Vietnam BeevR Technologies Full time $18,750 - $37,500 per year

Position:
Senior Smart Contract Engineer (Solidity/Rust)

Project:
Stealth-mode DeFi Protocol (DEX/AMM Focus)

Location:
100% Remote

Engagement:
Freelance / Contract / Full-time (Flexible based on performance)

1. About Project

We are a product lab building a Next-Generation Decentralized Exchange (DEX). The project is currently in Stealth Mode and aims to solve critical liquidity challenges in the market.

We are looking for a hands-on Senior Smart Contract Engineer to handle the core logic on-chain.

● You won't be bogged down by management duties. Your focus is purely on writing high-quality, secure code.

● You will implement specific modules (Liquidity Pools, Swaps, Staking logic) based on defined requirements.

2. Key Responsibilities

● Core Development: Write and deploy secure Smart Contracts (Solidity) for the DeFi protocol.

● Logic Implementation: Translate business logic (Tokenomics, Staking Rewards, Fee distribution) into efficient code. Your experience with Staking/Vesting/Marketplace logic will be heavily utilized here.

● Collaboration: Work closely with our Backend team to ensure smooth data indexing (Subgraphs) and API integration.

● Quality Commitment: Ensure code is optimized for gas efficiency and ready for third-party audits.

● Strict Delivery: Since this is a remote/flexible role, we require high commitment to deadlines. Tasks must be delivered on time to match the sprint schedule.

3. Requirements

● Experience: 3+ years in Blockchain Development with a strong portfolio of deployed contracts.

● Tech Stack: Expert in Solidity, Hardhat, and Familiarity with Rust/Solana is a big plus for our future roadmap.

● Domain Knowledge: Strong understanding of ERC standards. Experience building Staking systems, Vesting contracts, or NFT Marketplaces is highly valued (as the logic transfers well to DeFi).

● Full-stack Mindset: Ability to read/write (NestJS) to assist with backend integration is a major advantage.

● Professionalism: Responsive communication and ability to self-manage tasks effectively in a remote environment.

4. What We Offer

● Flexible Engagement: Open to Freelancers or Contractors. We care about Output, not hours online.

● Competitive Rate: Payment based on milestones or hourly rate (negotiable).

● Technical Challenge: Opportunity to work on complex financial logic (AMM curves) beyond standard CRUD apps.

5. How to apply

To help us understand your coding style quickly, please submit:

● GitHub (Priority): Link to your coding profile.

● Portfolio / Deployment (Optional but Recommended): If available, please attach 1 Transaction Hash or Contract Address of a project you deployed (Testnet or Mainnet is fine).

● CV: Updated resume.
