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 looking for a Product Designer to help shape the experience for the developers and teams who build on LangChain. You'll work across our core product surfaces, and depending on where the need is greatest, that could include how developers get from first signup to real production usage, as well as deeper platform workflows like debugging, evaluation, and observability.
The common thread is developers doing technical, often high-stakes work, and needing an interface that gets out of their way. You'll partner with engineering, product, and other designers to figure out where the friction is and design your way out of it.
What you'll do:
- Build a deep understanding of how developers actually use LangChain's products through interviews and feedback sessions so your design decisions are grounded in real behavior and address user needs
- Own the full design arc on your features — from early concepts to polished, shipped work
- Work across a range of product areas and design initiatives as priorities shift
- Collaborate closely with product, engineering and other key stakeholders to ship new features quickly
What you'll bring:
- 3+ years of fullstack product design experience ideally working on developer tools, AI, or complex SaaS products
- Sharp eye for detail, with a strong foundation across user-centered design, interaction design, and visual craft
- A track record of solving hard interaction design problems, particularly around dense technical data
- Data-driven decision making - you are comfortable driving user research, both with internal stakeholders and external customers, and using what you learn to inform your designs
- You take initiative and ownership of tasks end-to-end
- Strong technical acumen - you collaborate effectively with engineers to design things that are both well-crafted and feasible
- Start-up DNA - you thrive in fast-paced, highly dynamic environments
Annual salary range: $145,000-$185,000
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.

Frame your portfolio around LLM integrations
LangChain's core product is an AI orchestration framework, so portfolio projects that demonstrate hands-on experience with LLM pipelines, retrieval-augmented generation, or agent tooling will resonate far more than general full-stack work.
Verify LangChain's E-Verify enrollment before applying
H-1B and E-3 sponsorship requires the employer to participate in E-Verify. Confirm LangChain's enrollment status directly through the E-Verify employer search before investing time in the application process.
Target roles with clear specialty occupation language
USCIS requires H-1B positions to qualify as specialty occupations. Look for Product Engineer postings at LangChain that list a specific degree requirement in computer science or engineering, not just a preferred background, to support a stronger petition.
Negotiate timing around LCA certification requirements
Your employer must obtain a certified Labor Condition Application from the DOL before filing your H-1B or E-3 petition. Build at least three to four weeks of LCA processing time into your start date conversation with the hiring team.
Search open Product Engineer roles on Migrate Mate
Identifying which specific Product Engineer openings at LangChain are actively seeking sponsored candidates narrows your focus. Use Migrate Mate to filter and browse verified sponsorship-eligible roles at LangChain before applying.
Prepare for a technical screen that tests agentic systems depth
LangChain's interview process for Product Engineers typically emphasizes applied AI reasoning. Refreshing your understanding of multi-agent architectures, tool use patterns, and stateful workflows will sharpen your performance before the offer stage.
Frequently Asked Questions
Does LangChain sponsor H-1B visas for Product Engineers?
Yes, LangChain has a track record of sponsoring H-1B visas for Product Engineer roles. Sponsorship is generally tied to roles with a clearly defined specialty occupation requirement, meaning the job posting should specify a degree in a relevant technical field. If you're in H-1B cap season, confirm your timeline with the hiring team early, since the annual lottery runs in March for an October 1 start date.
How do I apply for Product Engineer jobs at LangChain?
Applications go through LangChain's careers page, where Product Engineer openings are listed with role-specific requirements. You can also find sponsorship-eligible Product Engineer positions at LangChain on Migrate Mate, which filters specifically for roles open to visa holders. Tailoring your application to demonstrate experience with AI developer tooling, LLM frameworks, or orchestration systems will strengthen your candidacy significantly.
Which visa types does LangChain use to sponsor Product Engineers?
LangChain sponsors both H-1B and E-3 visas for Product Engineer roles. The H-1B applies to most nationalities and is subject to the annual 85,000-slot cap and lottery. The E-3 is exclusively available to Australian citizens, carries a separate 10,500-slot annual allocation that has never been exhausted, and can be applied for directly at a U.S. consulate without waiting for a lottery result.
What qualifications does LangChain expect for a sponsored Product Engineer?
LangChain's Product Engineer roles typically require a bachelor's degree or higher in computer science, software engineering, or a closely related field. Practically, postings emphasize experience shipping production-grade AI features, familiarity with LLM APIs, and the ability to work across backend systems and developer-facing interfaces. Candidates with demonstrable contributions to AI tooling or open-source projects in the LangChain ecosystem tend to stand out.
How do I estimate a realistic timeline from offer to visa approval for a Product Engineer role at LangChain?
For an H-1B, count at least three to four weeks for DOL Labor Condition Application certification, then two to six months for standard USCIS processing, or two to three weeks with premium processing. E-3 applicants typically move faster since consular processing in Australia currently runs two to six weeks. Building these windows into your offer negotiation avoids last-minute delays.
