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.

Today, LangChain, LangGraph, LangSmith, and Agent Builder 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. 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.

Get Access To All JobsTips for Finding Customer Engineer Jobs at LangChain Jobs
Frame your LLM integration experience clearly
LangChain hires Customer Engineers to help enterprise clients implement and scale LLM-powered applications. Document specific projects where you deployed, debugged, or optimized AI pipelines, since that technical depth is what distinguishes you from generalist candidates.
Target roles where LCA filings align
Before applying, check DOL's OFLC disclosure data to confirm LangChain has filed Labor Condition Applications for Customer Engineer roles. This tells you the position has a sponsorship precedent and that the employer has engaged the DOL process for this function before.
Prepare your degree-to-role match early
H-1B sponsorship for Customer Engineer roles requires a qualifying specialty occupation, meaning your degree field needs to connect directly to the role. A computer science, software engineering, or information systems degree maps cleanly. An unrelated degree will require a credentials evaluation and potentially a step-by-step equivalency argument before USCIS.
Use Migrate Mate to filter verified Customer Engineer openings
Not every posted Customer Engineer role at LangChain will explicitly mention sponsorship. Use Migrate Mate to surface and filter verified visa-sponsoring openings at LangChain, so you're applying to roles where international candidates are genuinely in scope.
Negotiate offer timing around H-1B cap deadlines
If you're not currently in H-1B status, cap-subject filings must be submitted in April for an October 1 start. If you receive an offer outside that window, ask whether LangChain will extend the offer timeline or structure your start date around the next cap season.
Australian candidates should ask about E-3 processing directly
LangChain sponsors E-3 visas for eligible Australian citizens, which bypasses the H-1B lottery entirely. If you hold an Australian passport, raise this explicitly with the recruiter, since not all hiring teams default to E-3 without prompting, even at companies that have filed for it.

Find Customer Engineer at LangChain JobsFrequently Asked Questions
Does LangChain sponsor H-1B visas for Customer Engineers?
Yes, LangChain has a track record of sponsoring H-1B visas for Customer Engineer roles. If you're currently on another nonimmigrant status such as F-1 OPT or a prior employer's H-1B, LangChain can file a transfer or new petition. Cap-subject candidates need to align offer timing with the April registration window for an October 1 start date.
How do I apply for Customer Engineer jobs at LangChain?
Apply directly through LangChain's careers page or through Migrate Mate, which surfaces verified Customer Engineer openings at LangChain filtered by visa sponsorship eligibility. Before applying, tailor your resume to highlight enterprise AI implementation experience, specifically work involving LLM deployment, API integration, or developer tooling, since that's the core of what LangChain's Customer Engineering team does.
Which visa types does LangChain commonly use for Customer Engineer roles?
LangChain sponsors both H-1B and E-3 visas for Customer Engineers. The H-1B applies broadly to international candidates and requires a specialty occupation determination. The E-3 is available exclusively to Australian citizens and operates outside the H-1B lottery, offering a faster and more predictable path for eligible candidates in this role.
What qualifications does LangChain expect for Customer Engineer candidates?
LangChain's Customer Engineer roles typically require a technical background in software engineering or AI development, with hands-on experience deploying or integrating LLM-based applications. Familiarity with Python, REST APIs, and enterprise software environments is expected. Prior experience supporting developers or technical customers in a pre-sales or post-sales capacity is a strong differentiator for this function.
How do I plan my timeline if I need H-1B sponsorship at LangChain?
If you require a new cap-subject H-1B, the registration window opens in March and work authorization begins October 1 of the same year. USCIS processes petitions over several months after the lottery. Plan to secure your offer well before March and confirm with LangChain's HR team that they'll register you in time. Premium processing is available if you need a faster adjudication once your petition is selected.
