Hiring: GTM Engineer (Lifecycle & AI) Company: Cosign Location: New York, NY Job Posted Time: 2026-09-10 12:44:48 Target Skills & Keywords : CSS, HTML, HubSpot, LLM About the job Experience: •4-6+ years of lifecycle, CRM, GTM engineering, or email marketing experience; startup, proptech, fintech, or insurtech experience is a strong plus •Hands-on expertise with a modern ESP/CRM platform (Braze, Iterable, Klaviyo, Customer.io, or HubSpot), including journey building, segmentation, and integrations •Practical experience with AI tools and automation platforms for GTM (e.g. Clay, n8n, Zapier, ChatGPT/Claude, or similar), used to optimize lifecycle journeys and scale campaign operations •Proven track record building lifecycle programs from the ground up in a fast-paced environment: you've selected the stack and set up the flows, not just inherited them •Strong analytical skills: deliverability metrics, cohort performance, funnel analysis, and A/B test design are second nature Required Skills: •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. •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 and Sales: align outbound cadences with campaign objectives, keep messaging and talk tracks consistent, and maintain the GTM playbook library as our product and market evolve. Qualifications: •As a highly motivated and data-driven GTM Engineer, you take full ownership of the lifecycle and CRM function, from initial strategy to final campaign execution, without needing direction. You are deeply committed to your targets, remain structured under pressure, and distinguish true results from mere activity. •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 an email and automation wizard, comfortable running multiple campaigns at once, leveraging A/B/C testing, and using AI tooling, from LLM-based content generation to workflow automation and predictive analytics, to drive the highest-performing outcomes across the customer lifecycle. •You are also a strong cross-functional partner. You can influence without authority, align stakeholders on priorities and tradeoffs, and translate AI and technical concepts into clear business value for sales teammates, leadership, and partners. When you build something powerful, you make sure the whole team knows how to use it. Compensation: •Operational familiarity with real estate, rental, or insurance customer journeys is a bonus; curiosity about the space is a must Interested candidates, please apply directly through the job posting on company's career page or try via AI auto apply on this platform.
