IT Systems Engineer

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
