San Francisco, California, United States Optimism Full time

About Optimism

At Optimism, we are dedicated to enhancing the Ethereum ecosystem by providing scalable infrastructure solutions. Our mission is to empower developers in the crypto space by offering reliable and efficient tools, akin to what AWS and GCP achieved for traditional web applications.

Position Overview

In this role, you will collaborate closely with leadership to design, enhance, and maintain our rollup technology offerings. You will be responsible for developing custom precompiles and deploying whitelisted contracts that introduce innovative functionalities, while also expanding our support for emerging Layer 2 solutions. We value individuals who can rapidly grasp complex technical concepts, create proof-of-concept solutions, and autonomously identify key challenges to address.

Key Qualifications

  • Proven expertise in distributed systems, cryptography, and networking protocols.
  • Experience with various rollup technologies, understanding their components and trade-offs.
  • Familiarity with EVM node software development.
  • In-depth knowledge of the Ethereum Virtual Machine and its integration with external tools.
  • Proficiency in multiple programming languages, including but not limited to Golang, Rust, and Solidity.
  • Contribute to the strategic direction and roadmap of Optimism's product offerings alongside the team.

Why You Will Enjoy This Role

  • You are passionate about rollups and their transformative potential for Ethereum, and you are eager to develop top-tier tools and infrastructure.
  • You look forward to architecting, building, and deploying systems that facilitate connections with ecosystem partners.
  • You have hands-on experience with optimistic and ZK rollups and deploying applications across various chains.
  • You possess the ability to troubleshoot issues across the technology stack, including networking, performance, and memory management.
  • You take ownership of challenges from start to finish and are committed to acquiring any necessary knowledge to achieve your goals.

Our Technology Stack

Our infrastructure leverages Kubernetes, Postgres, and Cloud Tasks on GCP, while our applications utilize a blend of React, JavaScript/TypeScript, Go, Rust, and Postgres. While familiarity with these technologies is advantageous, we prioritize engineers with strong technical acumen and the capacity to quickly learn new tools and frameworks.
