Conversion Rate Optimization Manager Jobs in Arcadia, CA

About the Role
We're hiring a Director of Growth to be the right hand to the VP of Digital. You'll own day-to-day execution of performance marketing across Meta, Google, YouTube, TikTok, CTV, and Affiliate, lead conversion rate optimization and manage the digital product roadmap for buckmason.com.
This is a high-leverage role for an operator who can move fast across performance marketing, merchandising, UX, and engineering - translating strategy into daily action and measurable growth. You'll have meaningful ownership from day one and a direct line to senior leadership.
What You'll Do
Performance Marketing
• Manage day-to-day execution and optimization of paid media across Meta, Google (Search, Shopping, PMax), YouTube, TikTok, CTV, and Affiliate.
• Own pacing, budget allocation, and efficiency targets (ROAS, CAC, blended MER) across channels.
• Partner with creative teams to brief, test, and scale new ad creative on a fast cadence.
• Manage agency partners and in-house team; hold them accountable to weekly KPIs and monthly business reviews.
• Build and maintain reporting that ties spend to revenue, new customer acquisition, and contribution margin.
• Run a continuous incrementality testing program (geo holdouts, conversion lift, platform experiments) and use MMM signal to rebalance channel mix and decide where the next dollar goes.
Conversion Rate Optimization & Digital Product
• Own the CRO roadmap for buckmason.com - from homepage and PLP to PDP and checkout.
• Plan, prioritize, and run a continuous A/B testing program; report on lift, significance, and learnings.
• Use analytics, heatmaps, session replay, and customer feedback to surface the next highest-impact tests.
• Partner with UX, creative, and engineering to translate insights into shipped, measurable changes.
• Manage the feature roadmap for the e-commerce site - site search, navigation, personalization, account, and checkout.
• Write briefs and requirement docs, prioritize the backlog with engineering, QA new features, and own launch readiness.
• Maintain a clear point of view on what's next for the buckmason.com customer experience.
What You'll Bring
• 6-8 years of experience in digital, e-commerce, or performance marketing, ideally at a DTC or omnichannel apparel brand.
• Track record of driving CRO wins through a structured, hypothesis-driven testing program.
• Comfort writing briefs and requirement docs and shipping with a small engineering team.
• Ability to zoom in and zoom out - equally comfortable in the weeds of a Meta or Google account (building campaigns, auditing structure, troubleshooting a buyer's work) and stepping back to drive paid strategy, channel mix, and full-funnel measurement.
• Strong analytics chops - fluent in GA4, Shopify reporting, and at least one BI tool (Looker, Tableau, Omni, or similar).
• Excellent written communication and the ability to operate cross-functionally with creative, brand, merchandising, and engineering.
• Bias to action and comfort working in person with a tight, ambitious team.
• Shopify Plus experience.
• Apparel, fashion, or lifestyle brand background is a plus
Logistics

• Location: Buck Mason HQ, Los Angeles - onsite, 5 days/week

Sasha Koehn and Erik Allen founded Buck Mason in 2013 to simplify the American wardrobe. Meeting as neighbors in Venice Beach, they started designing and selling clothes out of a small studio off Abbot Kinney Boulevard. Sasha built the website and Erik created the brand's first collection of jeans and tees. Taking an architectural approach to design, they built each piece to last far beyond a single season. Obsessed with quality, they worked with local mills and factories to create the finest fabrics down to the thread. Today, Buck Mason offers a broad range of clothing and accessories with a continued commitment to making high-quality, modern American classics.
