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, LangChain, LangGraph, LangSmith, and Fleet 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.
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.
Location: Remote
Compensation
- Annual salary range: $130,000 - $195,000 USD
Compensation Philosophy:
We offer competitive compensation that includes base salary, variable compensation for relevant roles, meaningful equity, benefits, and perks. Actual compensation and offerings will vary based on role, level, and location. Team members in the EU, UK, and APAC receive locally competitive benefits aligned with regional norms and regulations.
Benefits
Benefits include medical, dental, and vision coverage, flexible vacation, a 401(k) plan, meals on in-office days in the US and more.

Build a portfolio around LangChain's core product
Pre Sales engineers at LangChain are expected to demo LangSmith and LangGraph to enterprise buyers. Before applying, build and document a proof-of-concept project using these tools so you can speak fluently to the stack in technical interviews.
Get your LCA timing right before accepting
Your employer must file a certified Labor Condition Application with the DOL before submitting your H-1B petition. Understand this step happens before your start date so you can plan your notice period or current status end date without creating a gap.
Frame your visa status early in conversations
Technical Pre Sales candidates at AI infrastructure companies often move fast through hiring pipelines. Disclose your visa type and whether you need new sponsorship or a transfer in your first recruiter screen to avoid offer-stage delays caused by legal review cycles.
Target open roles through Migrate Mate's job board
LangChain posts Technical Pre Sales openings that explicitly support visa sponsorship. Use Migrate Mate to filter for verified LangChain listings so you're only spending time on roles where H-1B and E-3 sponsorship is already confirmed.
Align your credentials to specialty occupation standards
USCIS scrutinizes Technical Pre Sales petitions because the role spans sales and engineering. Make sure your degree field and job description both anchor to a specific technical discipline, such as computer science or electrical engineering, rather than a general business or communications background.
Use cap-exempt timing if you qualify
If you're transferring an existing H-1B from another employer, LangChain can file a portability petition and you can start working as soon as USCIS receives it. This bypasses the April lottery window and removes a six-to-twelve-month wait from your timeline.
Frequently Asked Questions
Does LangChain sponsor H-1B visas for Technical Pre Saless?
Yes, LangChain sponsors H-1B visas for Technical Pre Sales roles. The company has an established pattern of supporting work visa filings for technical functions, which includes pre-sales engineering positions. If you're already on an H-1B with another employer, LangChain can file a transfer petition, letting you start work once USCIS receives the filing rather than waiting for approval.
How do I apply for Technical Pre Sales jobs at LangChain?
Applications go through LangChain's careers page. For visa-sponsored roles specifically, Migrate Mate surfaces verified LangChain Technical Pre Sales openings where sponsorship is confirmed, which removes the guesswork of filtering through listings that don't support work authorization. Prepare a portfolio demonstrating hands-on experience with LLM frameworks and enterprise solution design before submitting.
Which visa types does LangChain commonly use for Technical Pre Sales roles?
LangChain sponsors both H-1B and E-3 visas for Technical Pre Sales positions. The H-1B is the most broadly available and requires a bachelor's degree or equivalent in a specialty field. The E-3 is exclusive to Australian citizens and offers a simpler process with no lottery. Both require a certified Labor Condition Application from the DOL before the petition is filed.
What qualifications does LangChain expect for Technical Pre Sales candidates?
LangChain typically looks for candidates who combine a computer science or engineering background with direct experience in enterprise software sales cycles. Hands-on familiarity with LangChain's own product suite, including LangSmith for observability and LangGraph for agent orchestration, is a strong differentiator. Prior experience in a solutions engineering or pre-sales capacity at an AI or developer tooling company carries significant weight.
How long does the visa sponsorship process take for a Technical Pre Sales role at LangChain?
For a new H-1B, the timeline depends on where you are in the lottery cycle. Cap-subject petitions are filed in April and employment typically starts October 1. Premium processing reduces USCIS adjudication to 15 business days but doesn't affect the start date. H-1B transfers and E-3 visas move faster and aren't lottery-dependent, with E-3 consular appointments in Australia often available within a few weeks.
