CRO specialist job description (template)

Job title: Conversion Rate Optimization (CRO) Specialist, E-commerce

About the role: You’ll own the conversion rate of our online store. Your job is to find out why visitors don’t buy, turn those insights into A/B tests, and grow revenue per visitor month after month, using data, not opinions.

Responsibilities

• Analyse the full funnel (homepage, collections, product pages, cart, checkout, post-purchase) and find the biggest leaks.
• Research customer doubts from analytics, session recordings, reviews, surveys and support messages.
• Write test hypotheses and rank them by expected revenue impact.
• Design and run A/B tests with our testing tool; brief design, copy and development, or build tests with AI tools.
• Read results correctly (sample size, test length, revenue per visitor) and roll out winners.
• Report monthly on tests run, wins, losses and learnings.
• Work with paid media to match landing pages to ads, and with the e-commerce team on pricing, AOV and checkout.

Requirements

• 2+ years running A/B tests on e-commerce sites, with examples of tests you designed and their results.
• Strong analytics: GA4, Shopify Analytics or similar; comfortable with spreadsheets.
• Understanding of test statistics: significance, sample size, why not to stop early.
• Good UX and copy judgement, and a habit of starting from customer research.
• Experience with Shopify (and ideally Shopify Plus checkout) is a plus.
• Familiarity with AI tools for research, design and building test variants is a plus.

KPIs for the role

• Revenue per visitor (primary).
• Conversion rate and average order value.
• Number of tests shipped per month and win rate.
• Checkout drop rate and add-to-cart rate.

Salary range (US, 2026): about $75,000–$105,000 base for mid-level; $105,000–$145,000 for senior. (Salary sources and comparisons.)

CRO manager job description: what changes

A CRO manager owns the programme rather than individual tests. Add these to the template:

• Own the testing roadmap and the quarterly revenue target from CRO.
• Manage designers, developers, analysts or an agency.
• Set the testing standards: minimum sample sizes, test length, decision metric.
• Report to leadership on revenue impact.

US salary estimates for CRO managers sit around $104,000–$107,000 on average in 2026.

Interview questions that reveal real testers

1. “Tell me about a test that lost. What did you learn?” Real testers have plenty. (I paused one that cut orders from 13 to 5: here’s why.)
2. “Conversion went down but revenue went up. Winner or loser?” The right answer mentions revenue per visitor. (The price test example.)
3. “Our store gets 300 orders a month. How would you test?” Look for sample-size awareness: bigger changes, longer tests, fewer at a time.
4. “Where would you look first on our store?” Good candidates ask for funnel numbers before suggesting designs. (The funnel benchmarks.)
5. “Our add-to-cart rate fell but purchases rose. What happened?” Strong candidates recognise better-qualified clicks. (Example.)
6. “How do you decide what to test first?” The answer should be revenue impact and customer doubts, not personal taste.
7. “How would you run two tests on the same page?” One per page at a time, unless traffic is very high.

Before you post the job

The most common reason in-house CRO fails isn’t the specialist: it’s that tests wait weeks for design and development. Before hiring, make sure the role can actually ship tests: through your developers, AI tools, or an agency.
