About OpenServ
OpenServ is building next-generation infrastructure for AI Agent projects. We're creating fair, secure, and rug-proof token mechanics through innovative bonding curves with automatic DEX graduation. We're currently live on Base and expanding to Solana.
What We've Built
- Bonding curve price discovery mechanisms
- Anti-sniper protection with decaying tax systems
- Automatic DEX graduation
- Rug-proof liquidity with permanently locked LP tokens
The Role
We're looking for a Senior Web3 Developer to join our team and take ownership of our blockchain infrastructure across multiple chains. You'll work on maintaining and extending our existing EVM smart contracts on Base while leading the effort to port our protocol to Solana.
This is a high-impact role where you'll be working directly with cutting-edge DeFi primitives including bonding curves, automated market makers, token factories, and vesting contracts.
Responsibilities
Smart Contract Development (EVM)
- Maintain and enhance our Solidity smart contract suite including bonding curves, token factories, routers, and vesting contracts
- Write comprehensive tests and ensure 100% coverage on critical paths
- Perform gas optimization and security hardening
- Integrate with DEX protocols (Aerodrome)
- Manage contract upgrades and deployments on Base mainnet
Solana Development
- Port existing EVM smart contracts to Solana using Rust and Anchor
- Design and implement SPL token integration
- Build Solana program equivalents for our bonding curve, factory, and vesting systems
- Integrate with Solana DEXs (Raydium, Orca, Jupiter)
- Set up testing infrastructure for Solana programs
Backend Integration
- Work with our TypeScript backend to integrate on-chain and off-chain components
- Build and maintain blockchain indexers for event processing
- Implement transaction management and gas optimization strategies
- Develop API endpoints for blockchain interactions using Viem
Security & Best Practices
- Conduct internal security reviews and prepare for external audits
- Implement anti-exploit mechanisms (reentrancy protection, access control)
- Monitor and respond to on-chain incidents
- Document smart contract architecture and deployment procedures
Required Skills
Must Have
- 3+ years of smart contract development experience
- Strong Solidity proficiency with production deployments
- Rust programming experience (or strong willingness to learn quickly)
- Deep understanding of DeFi primitives: AMMs, bonding curves, liquidity pools, token standards
- Experience with Hardhat, Foundry, or similar development frameworks
- Familiarity with OpenZeppelin contracts and upgradeability patterns
- Understanding of EVM internals: gas optimization, storage layouts, assembly
- Experience integrating with DEX protocols (Uniswap, Aerodrome, or similar)
- Strong TypeScript/JavaScript skills for backend integration
- Experience with Viem or Ethers.js for blockchain interactions
Solana Requirements
- Experience with Solana development (Anchor framework preferred)
- Understanding of Solana's account model and program architecture
- Familiarity with SPL tokens and associated token accounts
- Knowledge of Solana DEX integrations (Raydium, Orca, Jupiter)
- Experience with Solana testing frameworks and local validators
Nice to Have
- Experience with bonding curve implementations
- Knowledge of token vesting and distribution mechanisms
- Familiarity with cross-chain bridges and interoperability
- Experience with subgraphs or blockchain indexing (The Graph, custom indexers)
- Understanding of MEV and transaction ordering
- Previous audit experience or security research background
- Open source contributions to DeFi protocols
Tech Stack
Current Stack (EVM)
- Smart Contracts: Solidity, Hardhat, OpenZeppelin
- Integrations: Aerodrome, Base L2
- Backend: TypeScript, Fastify, Viem, MongoDB, Redis
- Frontend: React, Wagmi, TanStack Query
Future Stack (Solana)
- Smart Contracts: Rust, Anchor
- Integrations: Raydium, Orca, Jupiter, SPL Token Program
- Infrastructure: Solana RPC, Helius/Triton
