The Challenge

Voltaire hit $1.4M ARR in 2 weeks with one founder and AI agents—now you're hired #1 to build the growth engine that turns this into a category-defining company. You're not executing a playbook; you're writing it.

Your Mission

Ship conversion infrastructure: full acquisition funnel with 24-hour First Deliverable system that prospects forward to co-founders

2

Build lead scoring and qualification automation that self-selects ideal prospects and feeds pipeline

3

Instrument complete attribution stack (PostHog + custom analytics) to identify what's actually working

4

Launch semi-automated outbound system using Clay, Apollo, and AI-native enrichment workflows

By 6 Months
1

Own and optimize client dashboard: deliverables, reports, billing, AI activity tracking—product-led growth engine

2

Win at SEO/GEO for govoltaire.com; establish AI marketing company as category authority through organic channels

Scale revenue engineering: optimize checkout, pricing, upgrade paths, and build infrastructure for product expansion beyond marketing

KPIs You'll Own

Customer Acquisition Cost (CAC)

Track blended CAC across paid, outbound, and organic to optimize unit economics above 85% gross margins.

Conversion Rate by Stage

Measure first touch → demo → trial → paid conversion rates to identify and fix funnel bottlenecks.

Monthly Recurring Revenue (MRR) Growth

Primary North Star—target sustained 20-30% MoM growth through systematic optimization of all channels.

Product-Led Growth Virality

Track % of new customers sourced through existing customer referrals and product-generated inbound.

Experiment Velocity

Number of validated experiments shipped per week; measure learning speed, not just win rate.

Company Intelligence

Voltaire is a fully autonomous AI business ($118K MRR, 15 days old) that runs client marketing through AI agents instead of humans—12 agents handle content, SEO, paid media, and analytics at 85-95% margins. The founder built the entire system solo and proved the thesis: small teams with massive leverage beat large headcount. Now expanding into sales, operations, finance, and customer success.

Is This Role For You?

For You If
  • You've shipped growth infrastructure before (funnel optimization, experimentation platforms, revenue engineering) and can own end-to-end without hand-holding.
  • You're comfortable with ambiguity—there's no playbook, and you'll need to define what 'winning' looks like alongside the founder.
  • You're AI-native: comfortable learning and shipping with new tooling (n8n, Clay, AI-assisted coding) rather than legacy stacks.
  • You care about metrics obsessively—you instrument first, ask questions later, and make decisions based on data.
  • You want founding equity and real leverage: a shot at being #1 at a company that might define a new category.
Won't Work If
  • You need a fully defined role, manager, and 6-month roadmap—this is 'write the playbook as you go' territory.
  • You prefer proven tactics over experimentation—Voltaire is proof-of-concept stage; every channel, every angle needs validation.
  • You're uncomfortable shipping AI-native tooling or learning n8n, Clay, and unfamiliar stacks on the job.
  • You want stability or traditional startup structure—this is a founder + hired gunslinger scenario with high uncertainty but high upside.

Interview Process

1

Founder call

Conversation about your growth infrastructure experience, how you'd approach the first 90 days, and vision alignment.

2

Case study deep-dive

Walk through a funnel you've owned: acquisition channels, experiments run, metrics, and what you'd do differently with Voltaire's AI leverage.

3

Technical assessment (async or live)

Small project: design a conversion infrastructure or experimentation framework for a hypothetical product (likely using tools in the stack).

4

Offer + equity negotiation

Post-offer conversation on equity, vesting, and role scope as founding GTM Engineer.
