We’re seeking a highly skilled Senior/Staff Backend Engineer passionate about solving complex problems and motivated to shape the MEV landscape on Monad with high-performance solutions. In this role, you will help design, build, and optimize MEV-related infrastructure, with a focus on block building, transaction ordering, and low-latency execution strategies etc. You’ll work on systems at the intersection of blockchain, trading, and networking, helping to advance the frontier of MEV innovation.

What You’ll Do

• Design and implement performance-critical backend systems for MEV infrastructure throughout the transaction lifecycle.
• Contribute to the development of infrastructure for validator-client integration, relay communication, and block propagation.
• Optimize code for latency, throughput, and reliability in adversarial network conditions.
• Stay informed about MEV developments in Ethereum, Solana, and other ecosystems

What We’re Looking For

• 4-10 years of backend programming experience with expertise in low-level languages like C++ and Rust (experience in both is a plus, but not required).
• Proven backend engineering experience in MEV infrastructure, trading/searching, or block-building organizations.
• Experience designing production-grade, low-latency, high-performance networking architecture and distributed systems.
• Proven track record of technical leadership and project ownership from start to finish.
• Ability to work autonomously in a fast-paced, collaborative remote environment with strong ownership.

Nice to Have

• Familiarity with blockchain internals and validator client behavior.
• Contributions to open-source MEV infra or tooling projects.
• Experience in performance tuning and networking stack optimization.
• HFT experience.
• Academic background from a top-tier university and/or experience at a well-regarded technology company
