About Upstack Data

Our flagship product, Signal , replaces broken browser-based pixels with reliable first-party server-side events to Meta, TikTok, and other ad platforms. We're a lean, AI-first team running offshore-first - most of our engineering, GTM, and operations roles are filled with PH talent.

About This Role

We’re looking for a Social Content Writer to own organic growth across LinkedIn and X for both Upstack and our founder’s personal brand.

You’ll create high-performing thought leadership content, ghostwrite in the founder’s voice, and build a consistent content engine that drives attention, engagement, and distribution of lead magnets and marketing initiatives.

Working closely with the Growth Marketing Manager, you’ll help shape content pillars, repurpose ideas into social content, and use AI tools to scale content creation and storytelling.

This is a writing-first role focused on LinkedIn/X growth, founder-led content, and AI-assisted content execution in a fast-moving startup environment.

What You'll Do

• Own Upstack's company social channels, including content planning, writing, scheduling, publishing, and engagement

• Collaborate with the Growth Marketing Manager to develop content pillars and support broader content marketing initiatives
• Promote lead magnets, educational resources, and marketing campaigns through organic social content
• Create high-performing social content using proven hooks, storytelling frameworks, and platform-native formats
• Repurpose blogs, webinars, podcasts, customer stories, and other assets into engaging social content
• Build and maintain a content calendar across founder and company channels
• Monitor conversations, engage with industry leaders, and grow Upstack's presence within relevant communities
• Track content performance and continuously refine content strategy based on audience insights and engagement data
• Leverage AI tools to accelerate research, ideation, drafting, content repurposing, and workflow automation

Requirements

• 2–4+ years of experience creating content for B2B SaaS, technology, startup, or founder-led brands
• Proven experience writing LinkedIn and/or Twitter/X content that increased audience engagement, reach, followers, or inbound opportunities

• Strong understanding of LinkedIn and Twitter/X content formats, audience behavior, posting cadence, and engagement strategies
• Exceptional writing, editing, and storytelling skills with the ability to adapt to different voices and audiences
• Strong understanding of hooks, content structures, thought leadership, and platform-native content creation
• Experience promoting lead magnets, webinars, newsletters, educational resources, or similar content marketing assets through social channels
• Experience using AI tools such as ChatGPT, Claude, Gemini, or similar platforms to support content creation, research, ideation, and workflow efficiency
• Ability to independently manage a content calendar, publishing workflow, and content distribution process
• Strong attention to detail and ability to produce high-quality content with minimal oversight
• Comfortable working in a fast-moving startup environment and taking ownership of outcomes

Nice To Have
