Office Manager

San Francisco, CA$90,000 - $110,000

About Us

At LangChain, our mission is to make intelligent agents ubiquitous. We build the foundation for agent engineering in the real world, helping developers move from prototypes to production-ready AI agents that teams can rely on. We began as widely adopted open-source tools and have grown to also offer a platform for building, evaluating, deploying, and operating agents at scale.

With $125M raised at Series B from IVP, Sequoia, Benchmark, CapitalG, and Sapphire Ventures, we’re at a stage where we’re continuing to develop new products, growth is accelerating, and all team members have meaningful impact on what we build and how we work together. LangChain is a place where your contributions can shape how this technology shows up in the real world.

Today, our platform includes LangSmith (Observability, Evaluation, Deployment, Fleet, and Sandboxes), our open source frameworks (LangChain, LangGraph, and Deep Agents), and the newly launched LangSmith Engine for autonomous agent improvement. We have 100M+ monthly open source downloads, 6,000+ active LangSmith customers, and 5 of the Fortune 10 use LangSmith in production (+ 35% of the Fortune 500 overall), including teams at Klarna, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, LinkedIn, Monday.com, Nvidia, and Bridgewater.

About the Workplace & Real Estate Team

The Workplace & Real Estate team builds the places where LangChain builds the future of AI agents. Our job is to make every office somewhere people want to be — spaces that run flawlessly, feel great to walk into, and reflect the craft bar of the company in every detail. We treat the workplace as a product: designed with intent, measured, and continuously improved. We run a small, high-agency team of on-site owners in each hub, and we automate the manual work rather than adding it — across two master-lease hubs (SF, NY) and coworking spokes as the company scales.

About the Role

The Office Manager owns our SF HQ end-to-end — both the on-the-ground experience and the systems that make it run. SF is our largest hub and headquarters, we hold the master lease, we're moving into new space, and we regularly host company and team offsites. You open and reset the space first thing every morning and are the face of the office through the day — and you build the tooling, standards, and vendor programs that keep it running consistently as we scale. This is a hands-on role for a builder who takes pride in a flawless space and in the systems behind it.

Location: This role is based on-site in our San Francisco (HQ) office, five days per week.

What You'll Do

Own the space & the craft bar

Open and reset the space first thing every morning — before people arrive, the office is clean, stocked, and ready
Keep the space super organized, neat, tidy, clean, and stocked at all times; it should always be on point and represent the quality of the company
Run a regular walkthrough punch list and stay on top of the details — wires tucked, chairs in, nothing out of place

Be the face of the office

Present through business hours as front-of-house: greet guests, welcome and guide new hires and visitors, and be the person people find
Plan and run local in-office events, team moments, and the offsites hosted at HQ

Run operations, vendors & budget

Manage facilities, supplies, snacks, and equipment; own on-site vendor relationships (cleaning, food, maintenance); serve as primary contact for building management and repairs
Rationalize and manage vendor programs — move us off ad-hoc ordering to contracted, consistent programs
Own budget tracking for the office; help track cost-per-seat and utilization; partner with Finance

Build the systems & standards

Own the workplace ticket queue in Console for your office and help build the shared SLA framework and resolution metrics
Deploy and own the workplace tech stack — desk booking, room scheduling, visitor management, mailroom/deliveries — partnering with IT on networking
Build and maintain SOPs, playbooks, and trackers; contribute to shared standards across sites
Own space planning and moves for your office (starting with the SF move) — communicated early and low-drama
Run life-safety for the site (emergency action plan, evacuation, first aid/AED, drills) as part of the company-wide program
Use AI to automate the manual work — tickets, vendor comms, inventory, invoice/billing reconciliation

What You'll Bring

Hard Skills

4–6 years in office/workplace management, facilities, or workplace operations in high-growth tech
Exceptionally organized, documentation-first, and project-management-driven — plans, budgets, and status always visible and current
Experience owning workplace systems (ticketing, desk/room booking, visitor management) and vendor programs
Demonstrated AI fluency — you already use tools like Claude to increase your leverage and reach for automation instinctively

Soft Skills

Hospitality / concierge mindset — you treat colleagues and guests as customers (hotel or premium-hospitality background a plus)
Maximum agency & ownership — you treat the office as your own; you fix things before they're reported and build the systems no one's asked for yet
High craft — you take pride in a spotless, on-point space and clean systems behind it
Reliability — committed to a consistent, on-site, 5-day presence
Run to the roar — calm and proactive when something breaks

Nice to Have

Hospitality background (hotels, premium service)
Experience supporting office moves or buildouts
Experience with LangChain, LangGraph, LangSmith, or comparable tools
