IT Engineer

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

• 4+ 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 use 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)
