Job description

Model ML is the AI workflow builder transforming how major financial institutions produce and validate client-ready work. Model ML converts complex, manual processes into fully automated AI systems that scale across global teams. In under a year, Model ML has become one of the fastest growing enterprise AI platforms worldwide and recently closed a $75 million Series A, one of the largest fintech Series A rounds ever. The round was backed by FT Partners, Y Combinator, LocalGlobe, QED, 13books, and other top global investors, bringing total funding to $90 million.

The Role:

We’re looking for a Growth Marketing Manager to build and scale Model ML’s growth engine across paid, organic, lifecycle, and experimentation. You’ll be one of the earliest hires on the marketing team, driving measurable acquisition, engagement, and awareness among some of the most sophisticated buyers in the world.

You’ll work closely with the Marketing Lead, Creative team, Sales, and Product to develop hypotheses, run experiments, analyze performance, and transform early wins into repeatable playbooks. This role is for someone who’s equal parts analytical and creative, loves testing new ideas, and thrives in an environment where speed matters as much as precision.

What You’ll Be Responsible For:

• Own paid experimentation across channels including LinkedIn, search, retargeting, and emerging platforms.
• Build lifecycle journeys that grow activation, engagement, and repeat usage across user segments.
• Develop email and in-product messaging that improves adoption of new modules and workflows.
• Partner with Product to structure experiments focused on usage, minutes, and retention.
• Partner with the Creative Director, Copywriter, and Designer to distribute content across LinkedIn, YouTube, and other channels.
• Track and analyze performance using HubSpot, GA, LinkedIn Analytics, and internal dashboards.
• Turn experiments into standardized playbooks that scale across markets.
• Collaborate with Sales to build targeted outreach and demand gen programs for key accounts.
• Work with Product Marketing to position new features and launches.
• Align with the Creative team to shape campaign concepts and bring them to market.

What You Can Expect:

• You’ll be building from zero—no templates, no red tape.
• You’ll collaborate directly with the CEO, Marketing Lead, and Sales team.
• Priorities will shift. Deadlines will tighten. You’ll be uncomfortable—but constantly learning.
• It will be the most creatively and intellectually demanding work of your career.

What We’re Looking For:

• 4 to 6 years of experience in growth marketing, demand generation, lifecycle, or performance marketing.
• Experience running experiments across paid social, search, and lifecycle.
• Strong analytical instincts, familiarity with attribution, and comfort working with data.
• Ability to write tight, clear messaging for paid ads, landing pages, and lifecycle sequences.
• Experience collaborating with creative teams to launch and optimize campaigns.
• Ability to work quickly, juggle competing priorities, and maintain a high bar for quality.
• Curiosity, initiative, and a bias for action.
• A strategic thinker who also loves rolling up their sleeves and shipping.
• Experience in B2B, fintech, SaaS, or enterprise GTM environments.
• Experience running experiments in HubSpot, Intercom, or other lifecycle tools.
• Familiarity with SEO or website optimization.

What We Offer:

• Direct access to the founding team (2x YC-backed exits).
• Competitive salary + meaningful equity.
• A rare chance to define how enterprise AI should feel and function.
• A culture of high trust, high intensity, and high impact.

To Close:

We are assembling a small group of people who want to build something iconic and are willing to push themselves to do it. If you are hungry, creative, and ready to make the defining career move of your life, we would love to meet you.
