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 GTM builders and automation wizards. We are looking for a hands-on, data-driven GTM Engineer (Lifecycle & AI) to build the lifecycle and CRM function from the ground up, powered by AI. This is a founding GTM role where you will own email, SMS, and CRM across the full customer journey, from the moment a renter starts an application through approval, lease-up, renewal, and referral, and across the property partners who drive our growth.

As the first dedicated GTM Engineer hire, you will own the entire stack: platform selection, segmentation, automated journeys, AI-powered personalization, copy, deliverability, and reporting. You will also be the connective tissue across our GTM motion, building the systems, playbooks, and AI workflows that make the entire revenue team faster and sharper, not just the marketing function. You will work directly with leadership to turn the funnel into an intelligent, AI-driven system, with every campaign tied to activation, conversion, and retention outcomes across the portfolio.

This role is ideal for someone who thrives in a startup environment, has built lifecycle programs from 0 to 1 before, is fluent in AI tools and workflow automation, and is excited to own a channel end-to-end while shaping how the whole GTM team sells, messages, and wins.

KEY RESPONSIBILITIES

• Own the lifecycle marketing engine: email and SMS across the full renter journey and the property-partner journey (onboarding, activation, expansion).
• Own the ESP/CRM stack end-to-end: platform selection, implementation, integrations with product and sales data, deliverability, and compliance (CAN-SPAM, TCPA).
• Build the AI tooling that powers GTM: AI agents, LLM-driven personalization, and workflow automation (Clay, n8n, Zapier, or similar), and help the broader team adopt them.
• Develop segmentation and personalization that speaks differently to renters, landlords, and property managers at every funnel stage, sharpened by AI-driven insights and predictive scoring.
• Build the automated journeys behind our core metrics: activation flows that convert started applications, nurture flows that turn approvals into signed leases, and retention flows that drive renewals and referrals.
• Own campaign execution from copy to send: write, build, QA, and ship campaigns yourself, with continuous testing across subject lines, send times, content, and cadence.
• Bridge Marketing an…
