Ecommerce PM work lives at the intersection of UX, merchandising, growth, and operational reality (inventory doesn't care about your roadmap). Here's what I'd hire for.
Skills that matter in ecommerce
- Funnel literacy — acquisition → browse → PDP → cart → checkout → repeat
- Experimentation — hypotheses tied to revenue/AOV/conversion, not vanity clicks
- Merchandising empathy — categories, search/browse, promos, and content ops
- Ops awareness — fulfillment, returns, stockouts, and how product choices create support load
- Analytics fluency — cohort retention, contribution margin instincts, not just sessions
- Stakeholder management — marketing, supply, CX, and eng rarely share one KPI
- Prioritization under peak pressure — holiday freezes, flash sales, and "can't break checkout" constraints
- Writing — crisp specs for surfaces that change weekly
What I'd probe in interviews
| Topic | Good signal |
|---|---|
| Checkout change | Talks risk, measurement, and rollback—not just UI polish |
| Search/browse | Separates relevance, recall, and merchandising overrides |
| Promo feature | Mentions margin, fraud, and CX edge cases |
Overrated vs underrated
- Overrated: memorizing every Shopify app
- Underrated: taste for reducing friction without wrecking trust or ops
Day-to-day application
- Guarding checkout changes behind stronger review than blog experiments
- Partnering with merchandising on search and category pain
- Reading contribution margin, not just conversion rate
- Planning freezes and rollback paths before peak events
