Semiotic Labs - Smart Contract Engineer (EVM Ecosystem)
Job Description
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 micropayments, pricing, and staking optimization.
Frontend / Dashboards
Build UIs for data visualization and interaction, including dashboards for:
Micropayment activity
Data providers and indexers (The Graph)
Delegation and staking optimization
Liquidation status tracking
Use React or similar frameworks to create intuitive, data-rich user interfaces.
Integration & Collaboration
Bridge contract logic with backend services and UI.
Work with cryptographers, AI researchers, and protocol engineers to integrate cutting-edge tools.
Contribute across Semiotic’s full suite of products.
Quality & Deployment
Write tests (unit, integration, end-to-end) across contract, backend, and frontend layers.
Maintain CI/CD pipelines for EVM deployments across testnets and mainnet.
Follow best practices in Web3 security and code quality.
