About the role:

Location: San Francisco, CA (on-site 5 days a week)

We're looking for a Social and Brand Marketing Manager to shape how developers and the broader tech ecosystem experience LangChain. You'll develop and execute our social media strategy, build our video content engine, and lead brand initiatives that expand our reach in the developer community and beyond. This means growing our presence on X, LinkedIn, YouTube, and emerging platforms, creating compelling video programs from thought leadership to product launches, and executing high-impact brand campaigns like our current billboard project.

This is a high-impact role where you'll work cross-functionally with product marketing, engineering, and education teams to translate LangChain's technical innovations into content and campaigns that resonate. We're looking for a strategic marketer who can develop cohesive content strategies while also rolling up their sleeves to execute—someone who thrives in fast-paced environments and loves building programs from the ground up.

You need to balance strategic thinking with hands-on execution. You'll develop content strategies and campaign roadmaps, then execute them by writing scripts, managing vendors, and optimizing based on performance data. You're excited about leveraging AI to improve content quality and efficiency.

What you'll do:

• Own social media growth — Drive follower growth, engagement rates, impressions, and web traffic from X, LinkedIn, YouTube, and other channels through consistent, high-quality content and community engagement

• Build our video content engine — Launch and manage video programs including podcasts, roundtables, customer stories, and product launch content that resonates with technical audiences

• Lead brand campaigns — Envision and execute brand initiatives like billboard campaigns and other awareness-driving initiatives that raise awareness for LangSmith

• Manage video production — Own end-to-end video production for launches and brand content, working with product marketing to translate technical features into compelling visual stories

• Manage vendor relationships — Develop and oversee relationships with video production agencies, freelance creators, editors, and content contractors to scale output while maintaining quality

• Create engaging content — Write scripts, social copy, video descriptions, brand campaign messaging, and other content that drives engagement and reflects LangChain's technical expertise and brand voice

• Optimize for performance — Analyze social, video, and campaign metrics to identify what's working and iterate rapidly to improve reach, engagement, and conversion

• Enable internal teams — Build playbooks and craft guidance that empower product, marketing, and engineering teams to confidently use social channels to amplify launches

• Experiment and innovate — Test new formats, platforms, and content types to stay ahead in the rapidly evolving AI landscape

What we're looking for:

• Experience: 2-6 years in social media marketing, video content production, or content marketing roles, preferably at developer-focused or technical product companies

• Track record of growth: Proven ability to grow social audiences and engagement—you've built and scaled social and video programs that consistently deliver measurable results in follower growth, engagement rates, and traffic

• Strong writing skills: Ability to write compelling, technically informed content for social media, video scripts, and various formats that resonate with developer audiences

• Video production expertise: Deep understanding of video production workflows, from concept development to post-production, with experience managing vendors, freelancers, and production schedules

• Developer marketing experience: Understanding of how to create content that engages technical audiences while making complex concepts accessible and interesting

• Data-driven mindset: Strong analytical skills with experience tracking social media and video metrics, using insights to optimize content strategy and prove ROI

• Cross-functional collaboration: Excellent communication and partnership skills—you work well with product marketing, engineering, and education teams

• Ownership mentality: You're a self-starter who thrives in ambiguity, takes initiative, and drives results with minimal direction

• Technical curiosity and creativity: Interest in AI/ML and the ability to understand and articulate technical concepts through visual and written storytelling

• Product minded: You’re willing to become an expert on our products and translate technical features into content that developers want to watch and share

Compensation: We offer competitive compensation that includes base salary, meaningful equity, and benefits such as health and dental coverage, flexible vacation, a 401(k) plan, and life insurance. Actual compensation will vary based on role, level, and location. For team members in the EU and UK, we provide locally competitive benefits aligned with regional norms and regulations.
