Senior Performance Marketing Manager, GTM Experimentation

About the company

At the company, we're on a mission to grow the small business economy. We handle the hard stuff — payroll, health insurance, 401(k) s, and HR — so owners can focus on their craft and their customers. With teams in Denver, San Francisco, and New York, we support more than 500,000 small businesses nationwide and are building a workplace that reflects the people we serve.

All full-time employees receive competitive base pay, benefits, and equity (RSUs) — because everyone who helps build the company should share in its success. Offer amounts are determined by role, level, and location. Learn more about our Total Rewards philosophy.

AI is a fundamental part of how work gets done at the company. We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process.

the company is looking for a seasoned performance marketer to own execution across paid social and emerging acquisition channels — testing new platforms, formats, and tactics to find what works before scaling. This is a high-visibility role at the intersection of performance marketing, channel experimentation, and AI-powered workflow design. You will own execution and day-to-day strategy for paid social and new channel tests, working within the company's demand generation framework, with clear accountability to pipeline and revenue targets.

As a member of the company’s Demand Generation team, you will be embedded specifically within Paid Acquisition, a focused group responsible for driving awareness and pipeline through paid media. This team operates with high autonomy, a bias for experimentation, and a culture of cross-functional partnership. We hold ourselves to a high standard, move fast, and genuinely believe that being AI-native is part of what it means to do this job well today.

• Own paid social strategy and execution across Meta, Linked In, Reddit, Quora, and Tik Tok, driving full-funnel campaigns from brand awareness through retargeting and conversion, with accountability to pipeline and revenue targets.

• Manage significant, multi-million dollar budgets with rigor, including campaign pacing, forecasting, budget-vs-actuals analysis, and making the case for paid social investment in imperfect attribution environments.

• Apply and help refine the company’s paid acquisition measurement framework, including attribution philosophy and budget allocation principles, in partnership with the broader marketing team.

• Lead creative strategy and testing at scale: briefing creative studios and agencies, structuring meaningful experiments, interpreting complex data sets to drive actionable insights, and building a clear learning roadmap.

• Serve as the team’s go-to expert on paid social and AI-powered marketing workflows, documenting playbooks and best practices for the paid acquisition team.

• Identify, test, and validate new digital media channels and formats beyond core paid social — such as Google Demand Generation campaigns and ChatGPT ads — running structured pilots, defining success criteria upfront, and making the call on scale vs. kill within existing budget guardrails.

• Support new product launches from 0-1 by building and executing the paid acquisition plan for launch moments — channel mix, budget, creative, and timeline — in partnership with Integrated Marketing and Product Marketing.

• Partner with Web Marketing to align on landing page strategy, message match, and post-click conversion, because paid social performance doesn’t end at the click.

• Use AI tools as a consistent, habitual part of your workflow: generating campaign briefs, developing copy variants, accelerating audience research, and building reusable systems that raise the bar for the whole team.

• Collaborate cross-functionally with Integrated Marketing, Product Marketing, Sales, Communications, and Web to align paid social with integrated campaigns and earned media moments, and bring performance data back upstream to influence creative production and asset strategy.
