Senior Growth Writer and Strategist

We're looking for a Growth Copywriter & Campaign Strategist who can craft not just compelling copy but also identify hooks, angles, and clever positioning strategies that drive real results for our B2B startup.

Runwise (www.runwise.com) is a fast-paced, customer-focused climate-tech startup that controls and runs the key energy systems (heating, water, etc…) in 7,000+ buildings throughout the US. Runwise’s unique hardware and software service significantly reduces energy usage, substantially lowering costs and carbon output. As of today, Runwise’s technology takes the equivalent of 100,000 cars worth of carbon emissions off the road each year.

This is not a traditional copywriting role. You're an expert in crafting narratives that resonate deeply with target audiences, sparking interest, urgency, and genuine buying decisions without ever sounding "salesy" or like “marketing”. Everything you do is an experiment, and your results are quantifiable. You use creativity, paired with your strategic insights, to directly influence business growth and customer acquisition - and you are able to do every stop of the process (from idea, hook, implementation and confirmation of results) yourself.

• Develop and execute clever, high-impact experiments driven by outstanding NOT SALESY / MARKETING copy delivered via email sequences, videos, landing pages, one-pagers, and campaigns.
  
• Find the unique angle, hook, or insight that positions our product as indispensable to our target audience.
  
• Collaborate cross-functionally with Sales, Marketing, Product, and Leadership teams to generate fresh ideas for campaigns and strategic messaging.
  
• Constantly experiment, measure, and refine messaging to increase engagement and drive revenue growth.
  
• Translate complex solutions into human, conversational, persuasive language that doesn’t feel like traditional marketing.
  

• 4+ years of experience in growth, marketing, writing roles at an early-stage or growth-stage startup.
  
• Proven ability to uncover insights, craft strategic narratives, and produce clever copy that converts.
  
• Demonstrated success in ideating, executing, and scaling creative marketing campaigns or growth experiments.
  
• Exceptional writing skills; you’re precise, persuasive, engaging, and effortlessly conversational.
  
• Data-driven mindset, with the ability to analyze performance metrics and iterate rapidly.
  
• Innate understanding of B2B buyers, particularly how to grab attention and drive urgency authentically.
  

• Have worked in a fast-paced, high-growth startup environment and thrived amid ambiguity.
  
• Can point to specific growth experiments or campaigns that you've executed which resulted in meaningful business impact.
  
• Have experience selling complex products or solutions in a B2B setting.
  

You’ll directly shape how our customers see us and influence the growth trajectory of the company. If you’re hungry to see your words and ideas translate directly into revenue, this is your opportunity.
