• Monitor CAC, LTV, and funnel performance to inform spend decisions
• Partner with external agencies or internal resources to ensure execution quality and reporting clarity
• Align email retargeting and lifecycle touchpoints with paid acquisition efforts to improve blended ROI

*This role does not need to be a hands-on media buyer, but must understand performance

marketing mechanics, metrics, and optimization frameworks.

Measurement & Analytics

• Own reporting dashboards for lifecycle KPIs
• Clearly communicate what’s working, what isn’t, and recommended tradeoffs
• Drive decisions through data — not opinion

What We’re Looking For

• Strong understanding of segmentation, deliverability, automation logic, and conversion funnels

• Comfort operating in ambiguity and making hard prioritization decisions
• Highly analytical and performance-oriented
• Experience in marketplace, auction, DTC, or high-consideration purchase environments is a plus

• A passion for cars and the collector market is preferred

Why SOMO?

A small, high-caliber team building something meaningful in the car space that is actually

differentiated from legacy sites & experience.

• Backed by RM Sotheby’s credibility
• Startup velocity, independence, and nimbleness
• Competitive compensation, and upside tied to growth
• True remote flexibility

This Role Is Ideal For Someone Who

• Thinks in funnels and lifecycle logic
• Gets excited about segmentation and conversion math• Loves testing subject lines as much as strategy decks
• Wants to own a primary revenue lever, not just execute tasks
• Understands that email is one of the highest-ROI growth engines in a marketplace
