ABOUT COSIGN

Cosign is the fastest growing prop-tech company in the United States revolutionizing the $4 trillion rental industry with a market-leading one-of-a-kind rent guarantee product. Our mission is to expand housing access for renters and boost occupancy for landlords. Backed by top entrepreneurs, venture capital firms, and real estate investors, Cosign is built by experienced landlords and managers for landlords and managers who deeply understand the rental market's needs.

OUR MISSION CONTINUED

Cosign is on a mission to expand access to housing by helping landlords approve more qualified renters without increasing risk. We partner with owners and property managers to close the qualification gap caused by conditional approvals, thin credit files, and the absence of guarantors, materially improving leasing conversion and occupancy. We're building toward a near future where every U.S. property offers Cosign to renters who struggle to qualify, expanding housing choice while helping owners and operators convert demand into signed leases.

OUR HIRING PHILOSOPHY

At Cosign, we seek exceptional talent with relentless intellectual curiosity, individuals who:

• Challenge the status quo and drive continuous improvement
• Demand excellence from themselves and their colleagues
• Identify and solve problems others don't even recognize
• Create innovative solutions others believe impossible

We deliberately seek these rare, high-impact performers who attract similar talent. While most companies avoid hiring these exceptional individuals due to their demanding nature, we actively pursue them. When we find someone extraordinary, we move quickly to bring them onboard.

We believe average talent builds average companies. By assembling a team of exceptional performers, we're creating the talent density needed to transform the rental industry and set new standards of excellence.

THE OPPORTUNITY

Calling all storytellers and brand builders. We're looking for a strategic, hands-on Communications Manager who can own how Cosign shows up everywhere, externally and internally, from leadership's LinkedIn to the sales deck in a rep's hand. You will build the communications function from the ground up and define how Cosign sounds at every touchpoint.

As our first Communications Manager , you will own the entire stack: owned-channel strategy across LinkedIn, blog, website, PR, and executive communications, plus the messaging frameworks, sales collateral, and enablement materials that arm Sales, Partnerships, and Customer Success to sell with confidence. You will build the content engine behind our executive thought leadership and our Partnerships team's outreach, while partnering closely with leadership to keep every customer-facing message clear, consistent, and on-position.

Reporting to the Head of Marketing, this is a player-coach role: you'll ship high-stakes content yourself while coaching and upskilling a Copywriter, raising the bar for every piece of writing that leaves the company. It is ideal for someone who thrives in a startup environment, has built a communications function from 0 to 1 before, and is excited to own the full narrative, inside and outside the company, in a fast-moving, early-stage context.

KEY RESPONSIBILITIES

• Own Cosign's external communications engine across LinkedIn, the website, blog, PR, executive communications, and every customer-facing channel, ensuring a consistent, compelling brand voice at every touchpoint
• Own the communications strategy end-to-end: editorial direction, messaging frameworks, brand voice, content planning, and cross-functional alignment across Marketing, Product, Sales, and Customer Success
• Build executive thought leadership that positions Cosign as an industry leader: managing leadership's LinkedIn presence, executive content, presentations, speeches, interviews, and other public-facing communications
• Drive the content and SEO strategy that builds awareness and authority: owning website messaging, blog content, organic growth, and continuously improving search performance in partnership with our design lead
• Lead PR, strategic communications, and high-impact initiatives: partnering with the Head of Marketing on media opportunities, AI-driven marketing initiatives, product launches, and company-wide communications projects
• Own sales enablement and internal messaging from strategy to execution: creating and maintaining presentations, one-pagers, case studies, battlecards, sales templates, launch communications, FAQs, webinars, and messaging documentation, ensuring every team tells a consistent story to prospects, customers, partners, and investors
• Coach and develop our Copywriter as a player-coach: setting the quality bar, giving structured feedback, and upskilling them on voice, AI-assisted workflows, and editorial judgment

ABOUT YOU

As a highly motivated and data-driven communications expert, you take full ownership of the communications function, from messaging strategy to final content execution, without needing direction. You are deeply committed to your targets, remain structured under pressure, and distinguish true impact from mere output.

You thrive in early-stage landscapes where processes are still evolving. Instead of seeing gaps as obstacles, you view them as chances to innovate, bring fresh ideas, and find energy in constructing something new rather than simply working inside it.

You are a storyteller at heart, comfortable adapting your voice across executives, customers, partners, media, and internal teams, and using SEO insights and AI to drive the highest-performing content.

PREFERRED EXPERIENCE

We are looking for a passionate communications leader who is excited to shape Cosign's voice and build a world-class communications function from the ground up.

• 3-5+ years of experience in Communications, Content Marketing, Corporate Communications, Editorial, Brand Marketing, or a related field, ideally within a startup environment
• Exceptional writing and editing skills, with experience creating content for executives, customers, sales teams, partners, and media while maintaining a consistent brand voice
• Proven experience building executive thought leadership, particularly on LinkedIn, and growing organic brand presence through strategic content
• Hands-on ownership of website content, company blogs, editorial calendars, and SEO-driven content strategies using tools such as Ahrefs, SEMrush, or Google Search Console
• Strong AI fluency, leveraging tools like ChatGPT, Claude, Gemini, or similar platforms to accelerate research, content creation, and editing workflows
• Experience creating sales enablement materials, including presentations, one-pagers, case studies, battlecards, and messaging frameworks, that support revenue teams throughout the customer journey
• Excellent project management skills, with experience coordinating multiple stakeholders and managing editorial workflows using tools like Notion, Asana, or similar platforms
• Strong cross-functional leadership and the ability to influence Product, Sales, Customer Success, Partnerships, and executive stakeholders without formal authority
• A passion for building systems from scratch, balancing strategic thinking with hands-on execution in a fast-paced, high-growth environment

WHAT MAKES THIS OPPORTUNITY DIFFERENT

This is an opportunity to join one of the fastest-growing companies in U.S. PropTech at a pivotal moment in our growth. You will shape how Cosign communicates with the world, building the voice, content engine, and communications strategy that define our brand across customers, partners, investors, and the broader industry.

You will work alongside a team of exceptional performers, partner directly with senior leadership, and have real ownership over strategy and execution from day one. From building executive thought leadership and scaling our content engine to shaping company messaging and sales enablement, your work will have a direct impact on our growth and market presence.

WORKING AT COSIGN

This is a remote role, with our Marketing team centered around Mexico City. We believe great work happens through both flexibility and connection, so you'll have regular opportunities to collaborate with teammates in person through weekly meetups and team gatherings.

Cosign is looking for someone who thrives in a fast-paced, high-ownership environment and is excited to build alongside an ambitious team. We'll give you the autonomy to make an impact, the support to grow, and the opportunity to help shape both our communications function and the future of housing.
