Summary

As a Senior Backend Engineer on our Modular Execution Environment (MEE) team, you’ll help architect and scale the MEE protocol – a modular execution layer for advanced blockchain operations designed to horizontally scale blockchains in a multi-chain world. This is not just application development – you’ll be building foundational infrastructure that underpins decentralized, cross-chain supertransactions and smart account interactions.

You’ll work across the entire MEE stack:

1. MEE Protocol – Develop the decentralized network and cryptoeconomic systems, working on P2P communication, slashing mechanisms, and storage proofs.
2. MEE Network Infrastructure – Build the foundational infrastructure, from bundlers to validators, supporting the MEE protocol’s decentralization roadmap.
3. Backend & Indexers – Design complex systems to aggregate, index, and interpret on-chain and off-chain data, powering real-time cross-chain operations.
4. Implementing Supertransactions - Develop and refine a novel data type that defines cross-chain operations (EVM and non-EVM). Supertransactions aggregate multiple on-chain and off-chain interactions into a Merkle tree, enabling seamless, complex multi-chain execution.

What You Will Be Doing:

1. Protocol Development – Contribute to core MEE protocol components, including slashing mechanisms, cryptoeconomic design, and validator infrastructure.
2. Infrastructure Design – Build the backend infrastructure that facilitates MEE’s transition from centralized to fully decentralized P2P execution.
3. Indexers & Aggregation – Develop and optimize indexing services that process and aggregate data across multiple blockchains into abstract supertransaction models.
4. Cross-Chain Execution – Design systems to handle seamless cross-chain flows, enabling developers to execute complex, multi-chain transactions with minimal overhead.
5. Scalable Backend Systems – Implement scalable microservices, APIs, and backend solutions to support high-throughput, low-latency blockchain interactions.
6. 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.

Requirements:

1. Experience: 3+ years of backend development with a focus on blockchain protocols, infrastructure, or decentralized networks.
2. Tech Stack: Proficiency in JavaScript/TypeScript, Node.js and Web3 frameworks (Ethers.js, viem).
3. Blockchain Expertise: Deep understanding in any of the following:
4. Account Abstraction (AA)
5. 4337 Bundlers
6. Smart Accounts & EIP7702
7. Storage Proofs (e.g., Herodotus)
8. Intent-Based Bridges (e.g., Across, Connext)
9. Cross-Chain Messaging (e.g., Axelar, LayerZero)
10. Gossip Networks & P2P Systems
11. Liquidity Fronting
12. MEV, Flashbots & UserOps
13. Merkle Trees, Sequencers & Rollups
14. Backend Mastery: Experience building high-performance, scalable infrastructure and working with decentralized architectures.
15. Collaborative Approach: Proven ability to work cross-functionally across protocol, backend, and product teams in a fast-paced, iterative environment.

Nice-to-Have:

1. Contributions to open-source blockchain infrastructure projects.
2. Familiarity with optimistic rollups, zk-rollups, or modular execution environments.
3. Experience developing validators, bundlers, or sequencers in a P2P blockchain environment.
4. Understanding of MEV mitigation, frontrunning, and cross-chain arbitrage solutions.
5. Familiarity with Rust and/or Go
