About So Shall We

We partner with mid‑market owners and executives in the US to drive bottom‑line growth with mutual upside. A rare combination of consulting, full-stack execution and aligned incentives to eliminate what is wrong with the agency model.

We are what remains. We make growth feel easy.

Because your growth is our business. Your Mission

As a CRO Specialist, you'll support the conversion optimization strategy and experimentation roadmap to drive higher conversion rates across client accounts. You'll work closely with senior CRO, Design, and Performance team members to execute testing initiatives, apply experimentation frameworks, and contribute to data-driven decision-making. This is a great opportunity to build deep expertise in A/B testing and behavioral insight while growing into a role with increasing ownership over client optimization programs.

This role blends hands-on execution with growing strategic input — from spotting optimization opportunities to helping launch and analyze experiments — and requires curiosity, attention to detail, comfort with data, and a genuine interest in understanding user behavior.

What You'll Do

Optimization Support & Delivery

Support conversion optimization programs across assigned clients, working alongside senior team members to define testing scope.

Help translate business goals and user insights into testing hypotheses (Problem → Hypothesis → Metric).

Assist end-to-end in experiments — briefing, spec support, QA, launch monitoring, and analysis, under guidance from senior CRO.

Contribute to lifting conversion rate and revenue per visitor by identifying friction points and UX improvement opportunities.
