Director, Conversion Rate Optimization

Siege Media is a full service GEO/AI search agency. Over time, we’ve realized that CRO is GEO. We’d like to hire a great leader to both deliver great direct outcomes, but also LLM outcomes as well. You will found and lead it: run CRO end to end for our first clients, define how Siege does CRO, and grow the team as the service scales.

Many of our clients are SaaS, fintech and e-commerce/consumer. We have a mix of high volume clients with enough A/B testing demand, and a smaller set that don’t. Ideally,you will be as comfortable shipping a research-backed redesign of a pricing page that gets 40 demo requests a month as you are running a properly powered test on an ecommerce checkout. You choose the right method for the traffic on hand, get changes live with our design and development team, and prove impact either way.

• Own the CRO strategy and results for a portfolio of clients, with the goal of building a team under you to execute the work as demand grows

• Run A/B and multivariate programs where volume allows: hypothesis backlog, prioritization, test design, sample-size and duration math, QA, analysis, rollout

• Run research-led optimization for low-volume sites: blog post CRO improvements, heuristic audits, moderated user tests, session replay and heatmaps, on-site and post-conversion surveys, message testing, competitive teardowns

• Turn findings into specific, buildable recommendations (wireframes, copy, annotated mockups, acceptance criteria) and hand them to Siege designers and developers for implementation; QA what ships

• Measure impact honestly: test readouts at agreed confidence for testable sites; pre/post KPI reads with seasonality control for the rest; no p-values where they don't belong

• Build the practice: methodology, deliverable templates, tiering rules (when we test vs. recommend), tooling stack, pricing inputs, and case studies

• Support sales: scope CRO for prospects, contribute to proposal decks and calls, and run a fixed-scope CRO audit product for clients below the testing threshold

• Partner with SEO/GEO, Content, and Analytics teams so landing pages built for traffic are also built to convert, and so conversion tracking is in place before optimization starts

• Hire and manage CRO strategists and analysts as the practice grows

• 6+ years in CRO or experimentation, with at least 3 years client-facing at an agency or consultancy

• Documented results on both kinds of site: powered A/B programs and low-traffic, research-led optimization (we will ask for examples of each)

• Fluency in GA4, a testing platform (VWO, Optimizely, Convert, or similar), session replay and heatmap tools (Hotjar, Microsoft Clarity, Full Story, Contentsquare), and a user-testing platform (User Testing, Maze, Wynter)

• Working statistics: power, minimum detectable effect, peeking, Bayesian vs. frequentist reads, and when none of it applies

• UX and persuasion judgment: you can critique a page without data and be right most of the time, and explain why

• Strong writing and presentation: client recommendations that a CMO acts on and a developer can build from

• Enough HTML/CSS/JS and tag-management knowledge to QA tests and implementations

• Experience building a service, playbook, or team from zero is a strong plus

• B2B SaaS and lead-gen experience is a strong plus;
  Shopify and ecommerce experience is a plus

• CRO methodology, tiering rules, and deliverable templates documented and in use

• Full ownership of 4 to 5 client programs with measured conversion lift on the majority

• At least one client sold within the first six months

• A repeatable audit product sold to at least 3 clients below the testing threshold

• Two publishable case studies

• Hiring plan for the first CRO strategist

• $130k+ bonus opportunities
