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 tooling
LangChain builds developer-facing AI infrastructure, so projects involving LLM orchestration, retrieval-augmented generation, or agent frameworks signal direct relevance. Contributions to open-source AI tooling carry more weight here than general web application portfolios.
Confirm E-3 eligibility before applying
If you hold Australian citizenship, the E-3 visa offers a faster, cap-exempt path for Product Software Engineer roles. Unlike H-1B, there's no lottery, and LangChain has sponsored both types, so clarify your eligibility upfront when corresponding with the recruiting team.
Target roles where product and engineering overlap
LangChain regularly hires engineers who engage directly with developer communities and shape product direction. Emphasizing experience owning features end-to-end, writing technical docs, or working with external API consumers strengthens your fit for their product engineering function specifically.
Time your H-1B application around the lottery window
USCIS opens H-1B registration each March for an October 1 start date. If your offer comes outside that window, negotiate a start date that aligns with cap filing or ask about cap-exempt pathways if LangChain qualifies as a research or nonprofit-adjacent entity.
Get your specialty occupation documentation ready early
LangChain's Product Software Engineer roles typically require a computer science, software engineering, or closely related degree. Gather your official transcripts, credential evaluation if your degree is from outside the U.S., and any publications or open-source contributions before the offer stage so filing isn't delayed.
Use Migrate Mate to find open roles
Filtering for Product Software Engineer positions at LangChain that actively include visa sponsorship is faster with a dedicated tool. Migrate Mate surfaces these roles specifically so you can apply before headcount closes and sponsorship confirmation gets complicated.
Frequently Asked Questions
Does LangChain sponsor H-1B visas for Product Software Engineers?
Yes, LangChain has sponsored H-1B visas for Product Software Engineers. The H-1B requires your role to qualify as a specialty occupation, which Product Software Engineer positions in AI infrastructure generally satisfy given the degree requirements involved. Sponsorship is employer-initiated, so confirm willingness early in the recruiting process rather than after an offer is extended.
How do I apply for Product Software Engineer jobs at LangChain?
Applications go through LangChain's careers page. Migrate Mate also lists their open Product Software Engineer roles filtered by visa sponsorship eligibility, which helps you confirm the position is open to international candidates before you invest time in the process. Tailor your application to demonstrate experience with developer tooling, AI frameworks, or API product development, since those map closely to what LangChain's engineering teams build.
Which visa types are commonly used for Product Software Engineer roles at LangChain?
H-1B and E-3 are the two visa types LangChain has sponsored for this role. H-1B is available to all nationalities but subject to an annual lottery, while the E-3 is exclusive to Australian citizens and has no lottery or annual cap. For engineers already in the U.S. on F-1 OPT, LangChain can file an H-1B during the annual March registration window to bridge the transition.
What qualifications does LangChain expect for Product Software Engineer candidates?
LangChain's product engineering roles typically require a bachelor's degree or higher in computer science, software engineering, or a related technical field. Beyond the degree, hands-on experience building developer-facing products, working with LLM APIs, or contributing to open-source projects in the AI ecosystem is consistently valued. Engineers who can move between product thinking and deep technical implementation are a strong fit for how these teams operate.
How do I plan my timeline if I need LangChain to sponsor an H-1B?
USCIS opens H-1B registration each March, with approved petitions taking effect October 1. If you receive an offer and your current status allows you to start before October, negotiate a start date that works within your authorized period. If you're between jobs, the 60-day grace period for H-1B holders gives limited time to secure a new sponsor, so beginning the LangChain interview process before that window closes is important.
