About Semiotic Labs
Semiotic Labs builds advanced Web3 infrastructure, autonomous agents, and cryptoeconomic protocols that power decentralized finance and data economies. As a core developer team for The Graph, Semiotic Labs is pioneering trustless, efficient, and scalable financial primitives.
Our suite of products includes:
• GraphTally a trust-minimized micropayment system for decentralized service providers.
• Allocation Optimizer: an Agent for dynamic stake distribution across subgraphs in The Graph.
• Dynamic Pricing Algorithm: Adaptive online query pricing for Indexers.
• Holographic Homomorphic Signature Scheme (H2S2): Cryptographic primitive aggregating signatures for efficient verification.
• State-Channel Micropayments (via GraphTally): Off-chain payments minimizing on-chain cost for low-value transfers.
• AutoAgora: AI-powered tool for query pricing and negotiation in The Graph.
• RL & Neural-Network Cost Prediction / zk-SNARK Enhancements AI-driven pricing, verifiable queries, and privacy-preserving proof mechanisms.
Role Overview
We’re seeking a Smart Contract Engineer (EVM-focused) to work across Semiotic Labs’ product suite. You will design and implement smart contracts, build scalable backend services, and develop data-driven dashboards. The work will touch on areas such as on-chain identity, agreements, micropayments, and DeFi logic, while integrating with advanced indexing and delegation mechanics within The Graph ecosystem.
As part of our team, you’ll juggle with:
Smart Contracts
• Design, implement, and deploy secure EVM smart contracts (Solidity).
• Build logic for identity, on-chain agreements, micropayments, and DeFi primitives.
• Conduct audits and optimizations for gas efficiency and security.
Backend Services
• Develop APIs and services integrating smart contracts with off-chain components (Node.js, Go, Python).
• Support products such as GraphTally and Allocation Optimizer with backend logic.
• Implement scalable infrastructure for
