Senior Performance Marketing Manager New York, NY · In-person · Full-time
About Affiniti
Fintech has existed for decades. Yet walk into almost any pharmacy, vet clinic, or local shop in America, and you'll find the same story: a business owner managing their finances with tools that haven't meaningfully changed since their parents ran the place. Affiniti is closing that gap. We're building the financial operating system for small businesses across America, and we're growing fast. Advertising and marketing here aren't support functions. They're the engine. You'll play a central role in making sure business owners across the country know something fundamentally better exists, and in pulling every lever available to get them on the platform.
The role
We're building our in-house paid acquisition function. You'll own Meta end to end as our in-house expert: strategy, account structure, daily optimization, testing, reporting, and insights. Once Meta is running at full strength, you'll lead our expansion into the next channels, starting with Google Ads and growing into other paid platforms like TikTok and LinkedIn. You'll report to our Head of Growth and work alongside another growth marketer and an in-house team of 3–5 senior designers, so you'll have the creative capacity to test at high volume. This role demands someone who treats performance marketing like a science, moves with urgency, and holds themselves accountable to revenue outcomes, not just campaign metrics. If you want a defined lane and a predictable playbook, this isn't it. If you want full ownership of what you build and the chance to scale something that genuinely matters to the people it serves, this is the role.
What you'll own
Meta, end-to-end
- Own the account day-to-day: budget allocation, when to scale and by how much, campaign and ad set structure, bid strategy, optimization events, and which ads to keep or turn off.
- Keep tracking airtight: Pixel, Conversions API, and offline conversion uploads that send qualified-lead and funded-account signals back to Meta.
Testing and creative strategy
- Build and run a structured testing roadmap across campaign structure, bid strategy, creative, placements, audiences, optimization events, geo holdouts, and anything else that changes how efficiently the account scales.
- Turn performance data into creative direction. Brief our in-house design team on the angles, hooks, formats, and verticals that are working and what to test next.
- Make sure a high volume of weekly creative is organized and launched correctly, with the right ad set, copy, headlines, and landing page.
Measurement and insights
- Report performance daily and weekly, and share insights and recommendations with our growth, design, and revops teams.
- Optimize for qualified pipeline, not form fills. Work with revops to tie spend to demos, applications, and funded accounts by vertical.
- Reconcile Meta, Google, and CRM data, and make decisions on what's actually incremental rather than on platform-reported numbers.
Channel expansion
- Within your first 6 months, lead our expansion into Google Ads, then into other paid platforms like TikTok and LinkedIn.
- Be open to expanding into our other acquisition channels, such as SEO, AEO, GEO, and email marketing. Experience in any of these is a plus but not required. What matters is that you learn fast and adapt quickly. We're hiring for high slope.
What success looks like
- First 90 days:Account audited and restructured; tracking verified end-to-end; daily and weekly reporting in place.
- 6 months:Meta scaling efficiently on qualified-lead CAC, not CPL; a steady testing cadence with documented learnings; Google Ads live.
- 12 months:You own a multi-channel paid acquisition program across Meta, Google Ads, and at least one more paid platform.
Requirements
- 4–6 years of hands-on performance marketing or media buying experience, in-house or at an agency.
- Full end-to-end ownership of Meta ad accounts spending $200K+ per month. Experience scaling toward $1M per month is a strong plus.
- Lead-generation experience: you've optimized for lead quality and downstream conversion, not just e-commerce ROAS or cheap cost per lead.
- Fluent in funnel metrics like CPL, CAC, LTV, CTR, CVR, and cost per qualified lead, and comfortable communicating decisions with data.
- You reason from first principles and make decisions strategically, not just tactically. For example, you can make and explain the case for running TOFU or brand ads that generate fewer qualified leads than BOFU ads but improve incremental performance, using data as proof.
- A deep understanding of attribution. You know why Meta, Google, and the CRM never agree on the same number; you've worked with CAPI and offline conversion uploads, and you don't take platform-reported metrics at face value.
- Able to work in person, full-time, at our New York office.
Nice to have
- Google Ads experience at $100K+ per month across YouTube, Search, and Display.
- Experience on paid platforms beyond Meta and Google, such as TikTok, LinkedIn, or Reddit.
- Performance marketing experience in finance or fintech.
- Experience marketing to independently owned small businesses, from healthcare practices like pharmacies, veterinary clinics, and medical spas to home services and the trades like HVAC, roofing, and pest control.
