Growth Marketing Lead

Alchemy•San Francisco, CA

8d•$180,000 - $220,000•Hybrid

About The Position

Alchemy is seeking a Growth Marketing Lead to strategically direct investment in growth across the entire funnel, from self-serve signups to the enterprise sales process. This role involves high ownership and strategic decision-making, determining where marketing resources and headcount are allocated for maximum return. The Lead will manage existing channels such as paid search, paid social, SEO, AEO, a nascent lifecycle program, and the company website, reallocating investment based on performance. They will also explore and test new channels, identify product-led growth signals, and improve visibility into the self-serve and enterprise sales funnels. This is a senior role for an individual experienced in building full-funnel growth measurement for developer-focused B2B companies, capable of ranking channels by ROI and acting on that data. While not starting from scratch, the role involves evolving an existing AI-powered SEO/AEO system, a defined tool stack, and engaged agencies, with the opportunity to build a team over time.

Requirements

8+ years in growth or performance marketing at a B2B company with a developer-focused audience and both self-serve and enterprise motions.
Track record of owning full-funnel measurement: connecting top-of-funnel spend to signups to pipeline, and using that to make investment calls, not just channel-level reporting.
Proven ability to rank and reallocate spend + efforts across channels based on ROI, and to kill or scale channels based on evidence.
Experience evaluating and managing agency relationships and a marketing tool stack, with the judgment to know what to keep versus replace.
Comfortable identifying, testing, and standing up entirely new channels rather than only running the established playbook.
Strong cross-functional operator: able to work with Product on in-product growth signals, with Sales/SDR on lead quality and funnel handoff, and with Product Marketing and Ecosystem Marketing on execution you delegate out.
Efficiency-obsessed: instinctively pressure-tests where a dollar or a headcount is going before committing to it.
Familiarity with AI-powered or AI-assisted growth initiatives.
Ability to be in office in SF or NYC 3x a week.

Nice To Haves

Startup experience building a growth function from 0 to 1, standing up measurement and channel testing where little existed, not just optimizing an established program.
Has built and led a team, or is ready to hire and manage one as the highest-ROI areas justify dedicated headcount.
Experience in crypto/Web3 or blockchain infrastructure marketing.
Experience marketing an API-first or infrastructure product.

Responsibilities

Own full-funnel visibility for Alchemy's growth motion, from self-serve signup through the enterprise sales flow, including the quality of leads reaching the sales team, so the company can see how every channel performs end to end.
Set the channel investment strategy each half: given current resourcing and goals, decide where marketing dollars and efforts go, and defend that call with data.
Own and continuously re-rank channel ROI, paid search, paid social, SEO, AEO, lifecycle/email, website, ecosystem/partner-driven channels, and any new channel you stand up, identifying the highest-ROI area each cycle and reallocating toward it.
Evaluate and evolve the existing tool stack and agencies: keep, renegotiate, or replace based on what's actually driving signups and pipeline.
Identify, pitch, and test new channels and signals, including product-led growth signals you pick up working with Product, as Alchemy's audience and the industry evolve, then scope and delegate what you find to the right owner: a product marketer, an ecosystem marketing manager, an agency, or your own hire.
Build and lead a team over time: propose and open headcount as the highest-ROI areas demand dedicated ownership, and directly manage the specialists and agencies you bring on.
Represent growth and channel performance in the twice-yearly marketing planning cycle and retro, as a primary voice in where the company focuses its tactics next half, backed by your own data.
