Senior Marketing Manager, Demand Gen

About Tonic.ai

Tonic.ai is The Fake Data Company. We help development teams generate high-fidelity synthetic data so they can build and test faster — without touching production data. Our products serve a range of use cases: from generating realistic synthetic datasets from scratch (Tonic Fabricate) to de-identifying structured and unstructured databases for testing and AI workflows.

The role

We're hiring an AI-native Senior Marketing Manager, Demand Gen to own the top of our funnel; from first impression to signed-up user. You're responsible for everything that happens before someone walks through the door.

You'll report to the Senior Director of Growth Marketing and work across multiple product lines and multiple motions (PLG, ABM). You'll own paid channels, email marketing, and ABM execution. You'll be measured against the pipeline and paid conversions your programs produce. You will write the ads, run the Clay workflows, launch campaigns, and optimize them. You’ll run experiments and know when to ask for the assets, support, or budget you need to move faster.

What you'll own

Paid acquisition

• Google Ads: search campaigns for all three products, with Structural's top-performing keywords requiring particular attention
• Paid social: LinkedIn, with potential to expand into Meta, Reddit, and other channels based on performance data
• Display
• Retargeting
• YouTube

Email marketing

• Acquisition email sequences targeting net-new prospects across Fabricate and Textual audiences
• Coordinate with SDRs on sequencing and messaging, but you own the strategy and copy

ABM: Tonic Textual

• Run account-based campaigns for Textual

Direct mail

• Run direct mail to high-intent ABM segments where digital isn't breaking through
• Test creative, list, and offer combinations with measurable response tracking

Experimentation

• Continuous test-and-learn cadence across creative, audience, and channel combinations
• Document results so the rest of marketing can learn from what worked and what didn't, and decide what graduates to scaled spend

Landing page & conversion optimization

• Optimize paid traffic destinations for signup conversion

What we're looking for

• 4–7 years in demand generation, growth marketing, or acquisition-focused roles
• AI-native operator - you use AI tools daily to move faster, automate repetitive work, generate creative variants, and unblock yourself without waiting on resources. You're not experimenting with AI; it's already how you work.
• Direct experience with acquisition for a PLG (product-led growth) or freemium motion
• Hands-on experience with Google Ads and LinkedIn Campaign Manager; you build and manage campaigns yourself, not through an agency
• Experience running email marketing programs, including copy, sequencing, and deliverability
• ABM experience - you understand account selection, multi-threading, and what it takes to get an account to engage
• Familiarity with Clay, Apollo, or similar enrichment/sequencing tools is a strong plus
• You've worked at a B2B SaaS startup. You know what it means to operate without a fully built infrastructure and figure things out as you go.
• You're comfortable being held to pipeline numbers, not just activity metrics.
• Strong enough writer to own your own ad copy and email copy without a copywriter on every asset

How you'll be measured

• Primary metrics: signup volume by channel and signup quality measured by downstream conversion to qualified opportunity.
• Secondary: channel CAC, payback period against modeled targets, and number of new channels graduated from test to scaled spend per quarter.
• Your 30/60/90-day ramp progresses from inheriting current campaigns to running independently against these numbers in pipeline reviews.

Why this role

You'll work directly with the Sr. Director of Growth Marketing — not in a large team where your work disappears into committee. What you build is visible, attributable, and impactful. Three products means variety and breadth; pipeline accountability means your work is tied to what the company actually cares about. If you like owning channels end to end and being measured against real outcomes, this is the role.

Synthetic data is one of the defining infrastructure categories of the AI era — and Tonic.ai is leading it. This is a rare opportunity to drive go-to-market for a platform that is genuinely disruptive: helping the world's engineering and AI teams build faster, ship safer, and stop waiting on data they can't touch.

You won't be maintaining a mature playbook. You'll be building the acquisition engine for a multi-product company in a market that is accelerating underneath us. Every campaign you run, every channel you crack, every experiment you graduate to scale is directly visible in revenue. The feedback loop is short. The impact is real.

If you want to do creative, experimental work — test unconventional channels, run bold campaigns, try things that haven't been tried in this category — and have immediate line-of-sight to what it produces, this is the role. You'll have the autonomy to move fast and the accountability to make it count.

Tonic.ai is an equal opportunity employer. We're building a team that reflects the diversity of our users and the problems they're trying to solve.
