Senior IT Support Engineer

About LangChain

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.

Today, LangChain, LangGraph, LangSmith, and Agent Builder are used by teams shipping real AI products across startups and large enterprises. Millions of developers trust LangChain to power AI teams at companies like Replit, Clay, Coinbase, Workday, Lyft, Cloudflare, Harvey, Rippling, Vanta, and 35% of the Fortune 500.

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.

About the role

In person 5 days/week in San Francisco, CA or New York, NY

• Be the face of IT at LangChain. Every interaction you have with an employee is an opportunity to build trust, reduce friction, and make someone's day a bit more pleasant.

• Own the support queue in Serval. Keep it clean, move fast, and resolve issues at the root rather than papering over them. Employees should rarely have to follow up.

• Serve as the escalation point for hard, ambiguous problems. When something doesn't have a clear answer or owner, that's yours to figure out.

• Own the employee onboarding experience from end to end. That means defining the process, building the automation behind it in Okta Workflows and Serval, and making sure every new hire is fully set up and productive on day one. IT should not be a bottleneck.

• Partner with the People team to continuously improve onboarding and offboarding as we scale, so the process gets better as the company gets bigger.

• Spot patterns in Serval ticket data and turn them into fixes.

• Build and maintain documentation and self-service resources that let employees help themselves.

• Manage our Mac fleet through Kandji, keeping devices enrolled, compliant, and configured correctly.

• Work closely with our IT Engineer and Security team on access reviews, identity hygiene, and compliance work.

• Handle hardware procurement, asset tracking, and inventory.

How to be successful in this role

• 4+ years of experience in IT support or systems administration at a fast-moving tech company

• Comfortable working autonomously. You figure things out, ask good questions, and don't wait to be told what to do next

• You have owned the onboarding or offboarding process before, not just executed a pre-defined run book.

• Hands-on experience with Okta, including building Workflows that reduced manual work

• Comfortable administering Google Workspace, Slack, Notion, and Zoom at an admin level

• Experience with Kandji or JAMF

• You use LLMs as a multiplier in your day to day work. Whether that is automating repetitive tasks, writing scripts faster, or breaking down a complex problem you have never seen before.

• Strong documentation habits. You write things down, keep them current, and build resources people actually use

• Solid networking fundamentals: TCP/IP, DNS, DHCP, VPN, and Wi-Fi troubleshooting

Nice to have

• Hands-on experience with LangChain Deep Agents, Claude Code or Codex for writing scripts, building automations, or solving technical problems faster

• Scripting experience in Python or Bash for automating repetitive tasks

• Familiarity with REST APIs and connecting tools via integrations

• Experience supporting a security or compliance program (SOC 2, access reviews, etc.)

Compensation & Benefits

• We offer competitive compensation that includes base salary, meaningful equity, and benefits such as health and dental coverage, flexible vacation, a 401(k) plan, and life insurance. Actual compensation will vary based on role, level, and location. For team members in the EU and UK, we provide locally competitive benefits aligned with regional norms and regulations.

• Annual salary range: $135,000-$185,00 USD
