Job description

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 role

We’re hiring an IT Systems Administrator to join the founding IT team in San Francisco. You’ll run most of our SaaS stack day to day, from maintenance and configuration changes to access and troubleshooting. You’ll also build the automation that keeps that stack running as we grow.

This is a role for someone who does a bit of everything: helping an employee that’s locked out, shipping a terraform change, and building an automation that removes a manual task. The ideal candidate has startup experience, is comfortable with ambiguity, and heavily leans into automation.

What You’ll Do

SaaS Administration

• Own the day-to-day administration of our SaaS stack, including maintenance, configuration changes, and license management
• Administer LangSmith, our product, and use APIs to automate admin work
• Administer identity and permissions across core SaaS platforms such as Google Workspace, Slack, GitHub, Zoom, and Microsoft 365

Automation and Tooling

• Develop scripts, integrations, and reusable workflows using low or no code tools
• Connect systems through APIs and event-driven workflows to reduce manual work

Identity Management

• Administer Okta and user access
• Manage Okta group rules that help define our RBAC policy
• Establish repeatable standards and automation for employee lifecycle, group management, application provisioning, and access reviews

Client Platform Administration

• Administer our MDM platform, Iru, to enforce policy configurations, patching, zero-touch deployment, and custom desktop environment configurations
• Automate the hardware lifecycle from procurement, assignment, return, and recycling

Core IT Operations

• Provide hands-on troubleshooting and support to employees in the office and remotely across hardware, software, networking, and SaaS tools
• Build and maintain the harness for our AI ITSM agent, including the tools, playbooks, and knowledge it needs to resolve issues on its own
• Write documentation and playbooks, and use recurring support issues to guide what to automate next

What You’ll Bring

• 3+ years of experience in IT systems administration or IT engineering, ideally at a fast-growing startup
• Experience administering a broad SaaS stack that includes Google Workspace, Slack, Notion, and AI tools like Claude and ChatGPT
• Hands-on experience administering Okta, including SSO, SCIM provisioning, and Okta Workflows
• Comfort with REST APIs, webhooks, and API authentication methods
• Experience using coding agents (e.g. Claude Code) as part of your day-to-day workflow
• Experience with a macOS MDM platform and endpoint security tooling
• Solid networking fundamentals (TCP/IP, DNS, DHCP, VPNs, wireless)
• Clear communication, with patience for non-technical users
• Annual salary range: $150,000-$170,00 USD

Compensation Philosophy

We offer competitive compensation that includes base salary, variable compensation for relevant roles, meaningful equity, benefits, and perks. Actual compensation and offerings will vary based on role, level, and location. Team members in the EU, UK, and APAC receive locally competitive benefits aligned with regional norms and regulations.

Benefits

• Benefits include medical, dental, and vision coverage, flexible vacation, a 401(k) plan, meals on in-office days in the US and more.
