Job description

Overview

You’ll own the experimentation program that turns traffic into sales pipeline and revenue. From landing pages and forms to ad-to-page scent and funnel health, you’ll find inefficiencies, fix them, and scale what works. You’ll partner closely with paid acquisition, web design, and Sales to improve conversion across the whole customer journey.

What you’ll do

• Build and run an experimentation engine: Create hypotheses, plan and execute tests, and ship a steady cadence of A/B and multivariate tests across landing pages, key site flows, and some ad campaigns.
• Optimize landing pages & forms: Improve message-market fit, UX, and page speed/Core Web Vitals with our web developer. Reduce drop-off on multi-step forms and Calendly/booking flows.
• Tighten ad-page relevance: Align creative, offers, and keywords with page copy and clear CTAs.
• Analyze and improve funnels: Identify leaks across the MQL→SQL→Deal→Won pipeline.
• Gain insights: Blend GA4/StatCounter funnel data with heatmaps, session replays, on-page polls, and user interviews to diagnose friction, ideate solutions, and implement them across departments.

What you look like

• 5+ years in CRO/experimentation for high-traffic, high-spend environments (B2B lead generation strongly preferred). Demonstrated wins improving lead-form CVR, CPL/CPA, booking rate, and SQL rate at meaningful scale.
• Fluency in test design & statistics (power analysis, sequential testing/Bayesian or frequentist, stopping rules, multiple-comparison discipline). Hands-on with A/B tools (Convert, Google Ads Experiments, Meta A/B), analytics (GA4, StatCounter), tagging (GTM), heatmaps/session replays (Hotjar, Clarity), and CRO-friendly CMS/LP builders (WordPress/Elementor).
• Strong copy chops and an eye for UX; can brief/QA design and dev and ship fast.
• Comfortable with data (pivot tables; basic SQL a plus) and Core Web Vitals implications for conversion.
• Proven experience with SEO +/- GEO; willingness to learn quickly if no GEO experience and put learnings into action.
• Willingness to work outside of your core discipline, across channels and work on messaging, propositions, etc. as needed on ad creative and ad copy.
• Willingness to work on marketing projects outside the scope of conversion rate optimization.

What success looks like (6–12 months)

• 5+ years in digital marketing with a strong focus on B2B performance marketing.
• Deep understanding of marketing fundamentals, analytics, and experimentation.
• Demonstrated ability to leverage AI tools to speed up execution.
• Proven track record managing meaningful ad budgets across Google, Meta, and LinkedIn.
• Experience optimizing funnels and landing pages using CRO best practices.
• Experience with email marketing platforms, influencer or affiliate campaigns.
• Proven track record in SEO strategy, content production, and performance measurement.
• Hands-on with tools like GA4, Framer, PostHog, and campaign managers (Google, Meta, LinkedIn).
• Excellent copywriting and design instincts, with the ability to create or direct the development of high-quality marketing assets.
• Experience with marketing automation platforms such as Zapier, n8n, Make, or similar tools.

Your first 30/60/90

• 30 days: Audit funnels, tracking, and past tests; establish experiment backlog and KPI baseline; fix top-1 instrumentation gaps.
• 60 days: Ship 3–5 high-impact tests (LPs, forms, booking flow), establish reporting cadence by channel/segment.
• 90 days: Scale winners, expand into personalization/offer tests, and roll out a playbook for ongoing page-speed and UX hygiene.

What You Get

• Competitive salary
• Performance‑based bonuses
• Software for Upskilling & Productivity
• Remote-first culture
• Work from anywhere
• Paid Time Off
• Health Insurance
• High autonomy, low bureaucracy
• Fast-track to leadership for high performers
