IT Systems Engineer

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 are seeking our second IT Engineer to join our growing team in San Francisco. Our team laid the foundation for IT at LangChain, and this role is critical to helping us mature and scale that foundation as the company grows. You'll bring deep technical expertise to our fleet management and SaaS administration, with room to shape how we manage our fleet, identity, SaaS stack, and the automation that runs the business. The ideal candidate brings startup experience, thrives in ambiguity, loves a good problem, and is excited to build scalable systems that support our global team.

What You'll Do

Infrastructure & Automation

Build and maintain our IT infrastructure and tech stack that scales with LangChain’s rapid growth

Drive automation initiatives to reduce toil and improve efficiency using scripts, APIs, and workflow tools

Implement monitoring and documentation practices that enable operational excellence

Client Platform Engineering

Reimagine how we deploy, configure, and manage our Mac fleet. MDM (Iru) is the foundation, not the entire solution however.

Design and build a secure, reliable, and maintainable desktop environment that replaces our current patchwork of one-off scripts with version-controlled, testable, and repeatable systems

Own our approach to custom security controls and application deployment across the fleet, so updates and configuration changes are consistent and easy to roll out at scale

Build the fleet management systems now so they hold up as headcount, and the fleet, keep growing

Security & Identity Management

Drive our identity strategy, implementing secure, scalable access controls following the principle of least privilege

Identify and implement security enhancements across our SaaS stack

Partner with our Security team to drive improvement of our enterprise security posture

SaaS Administration

Administer and optimize our growing SaaS stack, managing provisioning, access controls, and lifecycle management

Become IT's central administrator for LangSmith, our own product, developing deep fluency in its administration surface

Build automated workflows for LangSmith administration using its API paired with our automation tooling, reducing manual, toil-heavy admin work

Help IT stay fluent across the internal tools we run and support, including the LLM Gateway. Another LangChain product.

Core IT Operations

Provide support to employees globally across hardware, software, networking, and IT tools

Deliver great onboarding experiences for new hires, ensuring they have the right hardware, access, and setup so they can be productive from day one

What You'll Bring

5+ years of experience in IT engineering and systems administration

Deep proficiency with Okta and Okta Workflows

Fluency in at least one general-purpose programming language (Python, JavaScript, or similar) with demonstrated ability to write production-quality scripts and automation

Versed in the us of REST APIs, webhooks, and API authentication methods; you should be comfortable reading API documentation and building integrations between systems

Demonstrated ability to build meaningful automations that reduce manual work and improve IT operations

Hands-on experience with IaC using Terraform to manage and provision IT infrastructure and applications, and comfort applying changes within an existing Terraform codebase

Experience using coding agents (e.g. Claude Code) as part of your day-to-day engineering workflow to build and ship automation faster

Strong experience with a modern tech stack that includes Google Workspace, Slack, Notion, Claude, ChatGPT

Solid understanding of MDM platforms, and ideally experience going beyond baseline MDM with fleet/configuration management tooling to manage a fleet's security and application needs

Experience administering a large or complex SaaS stack, ideally including internal or AI/LLM-based products

Strong networking fundamentals (TCP/IP, DNS, VPNs, firewalls, switching, wireless, LAN/WAN)

Annual salary range: $150,000-$170,00 USD
