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 a Senior Technical Support Engineer to lead our customer support experience for highly technical users, from AI engineers to infrastructure architects. You’ll be on the front lines helping teams debug production LLM applications and agents, improve AI observability and evaluations, and unblock critical issues. You’ll also help define what world-class technical support looks like for modern AI platforms

Key Responsibilities

  • Be the go-to escalation point for technical support inquiries—diagnosing issues across customer setup, LangChain products, and deployment issues.

  • Work directly with engineering, operations, documentation, and product teams to resolve bugs, suggest patches, and advocate for customer needs.

  • Partner with Deployed Engineering to support critical enterprise customers.

  • Build and refine internal tooling, diagnostics, and runbooks for complex issue triage.

  • Lead post-mortems for critical incidents and feed learnings back into product and documentation.

  • Help refine KPIs for support health (MTTR, CSAT, bug recurrence) and drive continuous improvement.

  • Improve documentation and knowledge articles to improve 1-to-many resources and provide proactive support.

  • Mentor and coach other support engineers.

How to be successful in this role

  • 6+ years in technical support, solutions engineering, or SRE roles in deeply technical B2B environments (e.g., observability, infrastructure, data platforms).

  • Expert troubleshooting skills across APIs, SDKs, distributed systems, and cloud-native stacks.

  • Programming experience with Python. Bonus if you have TypeScript experience.

  • Hands-on knowledge of Kubernetes and Docker

  • Comfort working with logs, traces, metrics in Datadog, and 3rd-party integrations (e.g., OpenTelemetry, LLM providers).

  • Experience supporting enterprise customers and collaborating with engineering on complex escalations.

  • A bias for clarity and continuous improvement: you write succinct, helpful, and accurate responses and build a foundation for case deflection.

  • High ownership — want to do what’s best for the customer and the company and are relentlessly results oriented

Employer PERM history

No recent PERM filings on record

This employer's identity is verified, and no certified PERM case was found for it in FY2023, FY2024, FY2025.

Filing history reflects past employer behavior; it isn't a promise for this opening.

How Openbound evaluates sponsorship

Visa history uses official U.S. Department of Labor H-1B LCA disclosure data and USCIS H-1B petition history. Green card history uses DOL PERM disclosure data. Each is read for the employer as a whole, for roles like this one, and for this location, weighted toward the most recent fiscal years.

An employer is matched to its filing entities by verified legal name and reviewed aliases; a match is never made on a name resemblance alone. Where no verified entity can be matched, the page says so and draws no conclusion from the absence. 9 filing titles were examined for this employer.

What this posting states outranks history in both directions, and an employer's published policy outranks past filings. Filing history reflects past behavior; it is not a promise of sponsorship for this opening, and none of this is legal advice.
