Millions of developers trust Lang Chain 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. Lang Chain is a place where your contributions can shape how this technology shows up in the real world.

We're looking for a Social Marketer to own Lang Chain's voice across social channels and drive our video content strategy. In this role, you'll own growing our social media presence and engagement on X, LinkedIn, YouTube, and new channels while driving engagement and web traffic. You'll build and scale our video content engine—from thought leadership podcasts to product launch videos to technical roundtables.

This is a high-impact role where you'll work cross-functionally with our product marketing, engineering, and education teams to shape how the world experiences Lang Chain's brand. If you're a creative marketer who's equally comfortable writing compelling copy and managing video production, thrives in fast-paced environments, and loves building content programs from scratch, we'd love to hear from you. Today, we have strong technical content and an engaged developer community—you'll translate that into must-watch video content and social media growth.

You need to be ready to get your hands dirty and get things done. You're not afraid to write scripts, edit social copy, coordinate with video vendors, and own the metrics that matter. You're excited about and already using AI to improve content quality and efficiency.

What You'll Do

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

• Lead video production — Manage end-to-end video production for product launches, working closely with product marketing to translate technical features into compelling visual stories. You'll coordinate talent, manage production schedules, and oversee post-production

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

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

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

• **Enable and uplevel internal teams —**Build playbooks, guidance, and lightweight training that empower product, marketing, education, and engineering teams to confidently use social channels to amplify launches and initiatives

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

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: Interest in AI/ML and the ability to understand and articulate technical concepts through visual and written storytelling (bonus: familiarity with Lang Chain or similar AI frameworks)

• 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
