Role Overview

As a Senior Smart Contract Developer, you will be a key player in the architecture, development, and deployment of smart contracts for gambling protocols, tokenomics systems, and DeFi applications. This is a remote role with crypto-based compensation, perfect for developers who want to work on high-impact projects while collaborating with a global team of blockchain experts.

Key Responsibilities:

1. Smart Contract Design & Implementation
   • Architect custody-less deposit systems, payout logic, anti-fraud mechanisms, and tokenomics functions.
   • Write, test, and deploy secure smart contracts using Solidity (EVM) and optionally Rust/Solana.
2. Integration & Development
   • Connect contracts with VRF/oracle randomness providers.
   • Collaborate with frontend engineers to ensure smooth ABI/event/interface integration.
3. Testing & Optimization
   • Conduct unit, integration, fuzz, and property-based testing.
   • Optimize gas usage and perform formal verification of critical invariants.
4. CI/CD & Monitoring
   • Configure pipelines for continuous integration and deployment.
   • Monitor on-chain metrics and respond to incidents promptly.
5. Security & Audits
   • Identify vulnerabilities and implement secure coding practices.
   • Prepare contracts for audits and participate in code reviews.

Required Skills and Expertise

A successful candidate will have strong technical and analytical capabilities, including:

• Deep knowledge of Solidity/EVM internals (storage, memory, stack operations, edge cases).
• Familiarity with common smart contract vulnerabilities (reentrancy, oracle manipulation, overflow/underflow, signature replay).
• Experience in tokenomics design (vesting schedules, emissions, fee models, revenue-sharing).
• Proficiency in gas optimization and profiling (Forge/Anvil/Foundry, Hardhat).
• Ability to work with on-chain randomness and oracle integrations (Chainlink or alternatives).
• Strong GitHub/GitLab portfolio demonstrating clean, tested, and deployed code.

Preferred Skills: Rust programming, smart contract audits, cryptography, data structures, logical thinking, problem-solving, and protocol analysis.

Education & Experience

Candidates should meet the following criteria:

• 3–5+ years of software development experience.
• 2+ years specifically in smart contract development.
• At least 2 deployed on-chain projects (contract addresses required).
• Participation in audits, bug bounties, or CTFs is a plus.
• Upper-Intermediate English for effective communication.

Compensation & Work Model

• Remote-first role with flexible working hours.
• Overlap with EU timezones for 2–4 hours preferred.
• Payments made exclusively in crypto; submission of a valid wallet address is mandatory.
• Full-time or contract-to-hire arrangements available.
• Paid technical tests may be assigned as part of the hiring process.

Application Process

To apply for this role, candidates must submit:

1. Resume + Short Cover Letter (5–7 sentences highlighting relevant experience).
2. GitHub/GitLab Profile showcasing smart contract projects.
3. Contract Addresses of deployed work (Etherscan/Polygonscan/BSCScan).
4. Primary Wallet Address for crypto payments (ETH/SOL/BSC).
5. Optional: Links to audits, bug bounties, or CTF results.

Tip: Include details of your deployed contracts and explain the tokenomics or security considerations you implemented. This significantly improves your chances of selection.
