Paid Social Manager

Company Description

In 2019, we started building profitable startups from scratch. We brought together top engineering minds from places like Princeton and MIT to drive the highest success rate in the industry and turn company building into a science.

During that time, we’ve built ten high-growth companies, driving $200M+ in revenue. Along the way, we’ve developed an engineering approach to entrepreneurship rooted in algorithms and advanced mathematics.

Now, we’re working to automate company building to the point that we can press a button to launch profitable companies—ventures that can reinvest their own resources to become enterprises that help millions, or even billions, of people.

The Position

Mechanism Ventures is seeking a Paid Social Manager to own paid social strategy, execution, and profitability across our portfolio of startups. You will drive measurable growth through Meta Ads, TikTok Ads, and influencer programs, while developing scalable systems that accelerate the launch and growth of new ventures. The majority of this role is dedicated to driving profitable growth through paid social, rather than brand awareness or top-of-funnel initiatives.

In your first month, you’ll jump directly into a Paid Social mission within the portfolio to deliver positive ROI, then build scalable creative systems and programs to help launch companies from 0 to 1. You’ll work hands-on with campaigns and creatives while designing the frameworks that allow paid social to scale efficiently across multiple brands.

You’ll report directly to the VP of Growth, collaborating closely with cross-functional teams in growth, creative, SEO, and lifecycle. This is a role for someone eager to blend strategy, execution, and innovation — especially in using AI to pioneer next-generation paid social systems.

Key Responsibilities

• Own paid social growth and profitability across multiple portfolio companies while being a “go-to” for the portfolio on all things paid social.

• Own the end-to-end creative process for paid social, including creative strategy, brief development, and production, while leading ongoing testing across portfolio companies.

• Design and build a compounding, AI-powered creative system that dramatically accelerates our ability to produce and test high-performing content.

• Fully manage campaign strategy, activation, optimization, and daily client communication

• Develop testing and optimization frameworks to drive efficiency, ROAS, and sustainable growth.

• Incorporate new AI tools and software to uplevel campaign performance and creative iteration.

• Collaborate cross-functionally with paid search, SEO, partnerships, retention, and product teams to maximize results, for example collaborating with Lifecycle to create cross-function strategy.

• Collaborate directly with CEOs and senior stakeholders to translate business goals into high-performing paid social strategies that deliver results.

• Continuously optimize post-click experiences to improve funnel efficiency, conversion rates, and downstream revenue.

• Crack emerging platforms (TikTok, Pinterest, Snap, LinkedIn) and new acquisition channels.

• Codify all of your learnings into a "Paid Social Playbook"—a reusable, scalable asset that will be the go-to-market standard for every new company we launch.

• Report performance and insights to stakeholders, balancing short-term ROI with long-term scalability.

• Work closely with engineering to implement best-in-class tracking.

• Continuously refine paid social systems to improve performance, speed, and reliability.
