OP Labs builds Optimism, an open-source blockchain network that powers the next generation of financial infrastructure. Hundreds of companies, from the world's largest enterprises like Sony, Coinbase, Kraken, Uniswap, OKX, and Bitpanda to the most ambitious early-stage builders, use the OP stack to launch their own blockchains and bring their users onchain. Today, over 65% of Layer 2 activity on Ethereum runs through the OP stack.

We are a small team building at the speed of the ecosystem we support. We’re remote-friendly but the NYC office is our center of gravity. We've raised $178M from a16z, Paradigm, and others. We have our work cut out for us and are looking for exceptional people to join us.

Roles and Responsibilities

The EA & Office Manager will be a trusted partner to OP Labs senior leadership — keeping three executives organized while owning the day-to-day health of our NYC HQ. While these two mandates are distinct, both are critical to how OP Labs operates, and you are the primary owner of both.

What are the role responsibilities?

Provide executive support for the CEO, Chief Growth Officer, and VP of Engineering

• Manage complex calendars, travel logistics, and meeting preparation across three senior leaders

• Serve as a reliable point of contact between executives and stakeholders, handling communications with professionalism and discretion

• Coordinate and prepare materials for executive meetings, board preparation, and company offsites

• Support leadership offsites: coordination, materials, note-taking, and action item follow-up

• Establish new—and improve existing—administrative systems and processes

• Make recommendations with regard to time management, prioritization, delegation, and organization.

• Assist with ad hoc projects, events and travel arrangements as needed.

• Must be willing and able to travel internationally

Own day-to-day NYC office operations

• Partner with Finance and People Ops on expense reporting and budget tracking for office costs

• Build and manage relationships with building management, service providers, and office vendors

• Anticipate operational needs and proactively solve problems before they surface

• Coordinate desk setup, badge access, and first-day logistics for new NYC employees

• Plan and execute in-office events and team gatherings at NYC HQ

What skills do you bring?

• 5+ years as an executive assistant, ideally in a fast-paced startup or tech environment

• Experience managing office operations, vendor relationships, or facilities

• Exceptional organizational skills, impeccable attention to detail and strong written and verbal communication; able to represent executives professionally

• High EQ and discretion when handling sensitive information

• Proactive problem-solver who anticipates needs before they become issues

• Comfortable in ambiguity and able to context-switch rapidly

• Proficiency with Google Workspace, Slack, and common project and calendar tools

• Embraces AI tools as part of day-to-day work — using them to draft correspondence, prep materials, and handle research faster, with a curiosity for finding new ways to save time

• Experience booking international travel and managing multi-timezone scheduling
