By staking $SFUND, you gain the advantage of early access to purchase project tokens, enhancing your position within the Web3 landscape. Our industry encompasses Crypto, Gaming, IDOs, and INOs. We operate as a highly-driven and fast-paced startup, we embrace a remote work culture, allowing our team to collaborate from anywhere in the world.
We’re looking for an experienced Senior Solana Blockchain Developer who will play a key role in building next-generation decentralized applications across Solana and other leading blockchain ecosystems (Ethereum, Base, BNB Chain, Polygon, Avalanche, etc).You will lead the design, implementation, and maintenance of smart contracts and blockchain integrations that power core business logic, ensuring security, scalability, and performance across multiple networks.
Smart Contract Architecture & Development
· Design, develop, and deploy Solana smart contracts using Rust and Anchor framework.
· Write Solidity or Vyper contracts for cross-chain integrations or Ethereum-compatible deployments (ETH, Base, BNB Chain, Polygon, Avalanche).
· Develop and optimize programs for tokenomics models (staking, liquidity, farming, IDOs, etc.) with a focus on gas efficiency, security, and modularity.
· Implement and maintain token standards including:
· Solana SPL tokens
· ERC20, ERC721, ERC1155, ERC4626
Blockchain Integrations & Infrastructure
· Work with Web3 libraries such as ethers.js, web3.js, or @solana/web3.js to integrate smart contracts with backend and frontend systems.
· Build and maintain cross-chain bridges, indexing pipelines, and transaction monitoring services.
· Collaborate with DevOps to automate smart contract deployment pipelines and RPC infrastructure.
Backend & System Development
· Develop backend APIs and services using TypeScript / Node.js (Express, NestJS, or Fastify).
· Integrate blockchain logic with backend microservices, databases (PostgreSQL, MongoDB, Redis), and caching layers.
· Ensure strong observability and fault-tolerance (logs, monitoring, error recovery).
Quality, Security & Testing
· Conduct code reviews, enforce security best practices, and ensure contracts are audit-ready.
· Implement unit, integration, and fuzz tests for both on-chain and off-chain components
· Collaborate with auditors during formal security reviews and implement recommended remediations.
