Job Description
As a Rollup Engineer, you will play a pivotal role in shaping the future of Ethereum Layer 2 (L2) solutions. This position focuses on deepening technical expertise within the PBS (Proof of Burn) design space and the broader Ethereum L2 ecosystem. You will analyze the architectural nuances of various rollup implementations, identify scalability bottlenecks, and explore innovative approaches to enhance system efficiency. The role also involves collaborating with rollup developers to address critical challenges related to sequencer decentralization, ensuring robust and secure infrastructure for decentralized applications (dApps).
Key Responsibilities
- Develop a comprehensive understanding of PBS protocols, Ethereum L2 frameworks, and the technical trade-offs inherent in different rollup architectures.
- Collaborate with rollup teams to design and implement decentralized sequencer systems, ensuring fault tolerance, censorship resistance, and network security.
- Research, prototype, and evaluate advanced L2 PBS designs, including MEV-Boost mechanisms and MEV auction frameworks, to optimize transaction throughput and minimize gas costs.
- Engage with the Ethereum Foundation and community stakeholders to explore long-term pathways for enshrined PBS, balancing innovation with protocol stability.
- Conduct technical analysis of existing rollup solutions, identify performance limitations, and propose scalable upgrades to support growing user demand.
- Document architectural decisions, maintain technical specifications, and communicate findings to cross-functional teams and external partners.
Job Requirements
- Proven experience in blockchain development, with a strong focus on Ethereum L2 protocols and rollup technologies (e.g., Arbitrum, Optimism, Polygon).
- Advanced knowledge of cryptographic principles, consensus algorithms, and decentralized systems design to ensure secure PBS implementations.
- Expertise in smart contract programming (Solidity) and decentralized application (dApp) development for building and maintaining rollup infrastructure.
- Deep understanding of MEV (Miner Extractable Value) dynamics, including MEV-Boost and MEV auction mechanisms, to mitigate risks and optimize on-chain behavior.
- Strong analytical skills to evaluate technical trade-offs between scalability, security, and decentralization in L2 PBS systems.
- Ability to collaborate with researchers, developers, and community members to drive innovation in Ethereum's Layer 2 ecosystem.
- Excellent communication skills to translate complex technical concepts into actionable strategies for stakeholders and developers.
- Preferred: Experience with decentralized governance models, protocol design, and open-source development practices.
Technical Scope
This role requires a technical focus on optimizing rollup performance through research into PBS design patterns, MEV-Boost integration, and auction-based revenue models. You will work on solving critical challenges related to transaction finality, validator coordination, and network latency, ensuring seamless user experiences for L2 applications. The position also involves staying abreast of Ethereum's evolving roadmap, contributing to discussions on future upgrades, and aligning technical solutions with the goals of the L2 ecosystem.
