Startup Growth Lead

Company

Mechanism builds profitable companies and turns them into enterprises.

Since 2019, we’ve launched and scaled 10 companies while driving $200M+ in revenue by treating company-building as an engineering problem—not an art project. We combine rigorous validation, advanced analytics, and repeatable systems to dramatically increase the odds of success.

Today, we are pushing that model further: building an operating system for entrepreneurship that allows us to launch profitable, reinvesting companies with speed, precision, and minimal waste—companies designed to reach millions, and eventually billions, of people.

This role sits at the center of that system.

The Role

The Startup Growth Lead is a founding-level growth operator embedded full-time in a single, heavily pre-validated startup.

• You are not searching for an idea.

• You are not fighting bureaucracy.

• You are not spread thin across functions.

You are brought in to build and prove the growth engine—fast.

You will own growth end-to-end, from first experiments through repeatable, profitable scale. Your job is to turn a validated thesis, real resources, and a clean slate into a growth system that works—and then hand it off cleanly so the company can scale.

This is a co-founder–level role in practice, with accountability for outcomes—not hand-offs.

How This Works at Mechanism

Each company pairs:

• A high-caliber fractional CEO, responsible for overall company leadership and removing obstacles

• A Startup Growth Lead, responsible for designing, executing, and scaling the growth engine

• A centralized Mechanism team providing engineering, design, data, automation, and operational leverage

• Our explicit goal is to maximize your leverage—so small, correct inputs produce outsized results.

Think rolling boulders downhill, not pushing them uphill.

What You Own

You are accountable for:

• Growth strategy and prioritization

• Channel discovery, testing, and validation

• Building a repeatable, profitable acquisition system

• Customer understanding and feedback loops

• Proving positive unit economics and a path to scale
  

You are not responsible for:

• Inventory management

• Cash management or P&L ownership

• Customer support

• General operations

Those functions exist to support growth—not dilute it.

What You’ll Do

• Own growth end-to-end for a newly launched company, with profitability as the primary KPI

• Design and execute the growth strategy across acquisition, conversion, retention, and monetization

• Build and maintain a clear growth model defining assumptions, targets, and constraints

• Design fast, disciplined experiments to validate demand, channels, pricing, and positioning
  

Personally own or directly oversee:

• Paid acquisition (especially Google Ads and Meta)

• Conversion rate optimization

• Landing pages and funnel testing

• Retention and lifecycle systems where relevant

• Scale what works, kill what doesn’t—quickly and decisively

• Partner closely with product, engineering, and design to translate growth insights into high-leverage changes

• Participate in board meetings to share growth strategy, results, learnings, and blockers

• Document systems, playbooks, and learnings so they can be reused across future launches

• Leverage AI and automation to increase speed, clarity, and effectiveness

• Transition growth ownership to a long-term team once the engine is stable and repeatable

The goal is to launch, validate, scale, and transition growth ownership in under 12 months—then move on to build the next company.

Who This Is For

This role is ideal if you:

• Are a high-ownership growth operator with founder-level instincts

• Thrive in early-stage ambiguity but demand real resources and leverage

• Move extremely fast without sacrificing rigor

• Care deeply about unit economics and profitability

• Want co-founder impact without being diluted by non-growth execution

• Want to work alongside some of the strongest operators of your career

This is not a traditional “Head of Growth” role inside an existing company. It is a chance to repeatedly build the growth foundations of companies designed to matter, inside a system optimized for speed, clarity, and compounding leverage.

Requirements

• 5+ years building and scaling growth engines in early-stage companies

• Deep hands-on experience with Google Ads, Meta Ads, and CRO

• Strong first-principles and systems thinking

• High-speed, high-quality execution under ambiguity

• Strong written and verbal communication

• Comfort leveraging AI, automation, and modern growth tooling

Logistics

• Full-time, US-based, fully remote

• Significant overlap with US ET required

• High-commitment role by design

Introductory Period

The first 90 days are an introductory period for performance and fit evaluation. Employees are not eligible for unlimited PTO during this time, except for pre-approved time off confirmed in writing prior to the start date. Unlimited PTO begins after successful completion of the introductory period.

Time Commitment

This role is full-time and will need to overlap with US ET for the majority of the workday. It is an exciting opportunity that demands a level of dedication beyond the standard 9 to 5. We need someone who's willing to go above and beyond to help us achieve our ambitious goals, and who's eager to put in the effort to make a real impact.

Location

US-Based - Fully remote.

Compensation

Our compensation packages are designed to make this your dream job for the short and long term. Each compensation package is tailored to suit your priorities and can include base, equity in the companies we help build, and performance bonus based on the success of our portfolio companies. Benefits include medical, dental, vision, and an unlimited time off policy with a two-week minimum.
