Build and scale the Modular Execution Environment (MEE) protocol, a modular execution layer for advanced blockchain operations. This involves developing decentralized networks, building infrastructure, and designing systems for cross-chain execution.

Requirements

  • Experience: 3+ years of backend development with a focus on blockchain protocols, infrastructure, or decentralized networks.
  • Tech Stack: Proficiency in JavaScript/TypeScript, Node.js and Web3 frameworks (Ethers.js, viem).
  • Blockchain Expertise: Deep understanding in any of the following: Account Abstraction (AA), 4337 Bundlers, Smart Accounts & EIP7702, Storage Proofs(e.g., Herodotus), Intent-Based Bridges(e.g., Across, Connext), Cross-Chain Messaging(e.g., Axelar, LayerZero), Gossip Networks & P2P Systems, Liquidity Fronting, MEV, Flashbots & UserOps, Merkle Trees, Sequencers & Rollups.
  • Backend Mastery: Experience building high-performance, scalable infrastructure and working with decentralized architectures.
  • Collaborative Approach: Proven ability to work cross-functionally across protocol, backend, and product teams in a fast-paced, iterative environment.

    • Responsibilities

  • Protocol Development– Contribute to core MEE protocol components, including slashing mechanisms, cryptoeconomic design, and validator infrastructure.
  • Infrastructure Design– Build the backend infrastructure that facilitates MEE’s transition from centralized to fully decentralized P2P execution.
  • Indexers & Aggregation– Develop and optimize indexing services that process and aggregate data across multiple blockchains into abstract supertransaction models.
  • Cross-Chain Execution– Design systems to handle seamless cross-chain flows, enabling developers to execute complex, multi-chain transactions with minimal overhead.
  • Scalable Backend Systems– Implement scalable microservices, APIs, and backend solutions to support high-throughput, low-latency blockchain interactions.
  • Collaborate on Cutting-Edge Tech– Work with blockchain engineers, cryptographers, and product teams to integrate novel technologies like storage proofs, intent-based bridges, and gossip networks.

    • Benefits

  • Flexible Working Hours: Enjoy autonomy over your schedule.
  • Generous Vacation Policy: 25 days vacation per year plus public holidays.
  • Competitive Salary: With regular performance reviews.
  • Token Allocation: Be rewarded with tokens as part of our compensation package.
