Founding Software Engineer (Equity-Only | Own & Scale an AI Sales System)

⚠️ This is NOT a junior role.

If you haven’t built and shipped real systems in production and taken ownership of them, this role is not for you.

---

We’re not starting from zero.

We’ve already built the core.

Now we need someone to take ownership and make it real.

What we’re building

At GrowthEffect, we’re building:

→ Full AI Sales Teams (Inbound + Outbound Autonomous AI Agents)

AI agents that:

• respond to inbound leads in seconds
• qualify and book meetings
• run outbound, outreach with deep research
• create pipeline on autopilot

This is not an idea!

It’s already live.

But it needs to be:

→ cleaner

→ faster

→ more reliable

→ properly scaled

The real problem

Right now:

• The system exists
• Agents exist
• Customers exist

But everything needs to be tightened, improved, and owned

What you’ll actually do

• Take over and own the technical side
• Clean up and stabilize existing systems
• Improve agent performance and reliability
• Ship fast iterations
• Work with a small part-time team and bring structure

This is not a “build in isolation” role.

👉 This is a take control and make it work role.

The setup

• Early stage
• Equity-only first (no salary for now)
• Part-time contributors already exist
• Product is already in motion

We need someone to step in and take the wheel

What we’re looking for

We don’t care about titles.

We care if you can own systems.

• 4+ years of experience (or real equivalent)
• You’ve worked on real products in production
• Comfortable system building and improving the existing (not just building clean ones)
• Strong with backend, APIs, LLMs, orchestration
• Can take responsibility and not wait for instructions

Tech stack (you should be comfortable here):

• Node.js, and TypeScript

• APIs, async systems, event-driven flows

• LLM integrations / agent orchestration

Who this is perfect for

• You’ve built things but never truly owned one
• You want to step into a real technical leadership role
• You like fixing and scaling real systems (not just greenfield projects)
• You want to shape a WORLD-GRADE product

Who this is NOT for

• You only like building from scratch
• You need perfect systems and clean architecture from day one
• You want stability over ownership

What you get

• Only Equity first, salary follows later
• Real ownership
• A product that already exists (not just an idea)
• Direct impact on growth and revenue
