Help Brands Win on Amazon - and Love Where You Work

Role: Marketplace Manager
Location: San Diego, CA 92101 (Onsite at Symphony Towers)
Compensation Range: $90,000-$110,000 DOE

At Luminize, we help brands win, and as one of the top 5 Amazon sellers in the US, we’re looking for top performers to grow with us.

We're looking for a sharp, driven marketplace operator who thrives in a fast-paced, high-growth environment. As our Marketplace Manager, you'll own end-to-end execution across Amazon International and off-Amazon channels — connecting strategy to results across a cross-functional team. You'll be the central hub for your platforms, driving revenue, account health, and expansion for some of the most exciting brands in the Amazon ecosystem.



What You’ll Own
  • Marketplace Strategy & Growth Define and execute e-commerce growth strategies aligned with company goals. Lead international Amazon marketplace launches (UK, EU, CA, and more) and expand presence across off-Amazon platforms including TikTok Shop, Walmart, Coupang, and Target.
  • Listing Management & Optimization Launch, manage, and optimize product listings across Amazon International and alternative marketplaces — including content, SEO, A+ content, and storefronts.
  • Advertising Collaboration Partner with PPC Strategists to plan and optimize campaigns. Translate business goals into clear ad strategies and creative requirements, track ad ROI, and guide spend allocation with data-driven recommendations.
  • Cross-Functional Execution Coordinate projects across Brand Management, Advertising, Supply Chain, Compliance, Catalog, and Content teams. Identify bottlenecks and implement process improvements across the e-commerce workflow.
  • Analytics & Performance Monitoring Monitor KPIs, sales trends, and campaign performance to inform decision-making. Conduct competitor analysis and identify market expansion opportunities.
  • Inventory & Operations Support inventory forecasting, replenishment, and logistics coordination. Ensure compliance with marketplace policies and resolve operational issues quickly.
✅ What You Bring
  • Bachelor's degree in Marketing, Business, or a related field, or equivalent work experience
  • 3+ years of e-commerce management with demonstrated success scaling sales on Amazon and alternative marketplaces (Walmart, TikTok Shop, Amazon Canada, etc.)
  • Strong understanding of retail media and digital advertising principles (Amazon PPC, Walmart Connect)
  • Excellent project management skills: able to prioritize, delegate, and execute independently without continual oversight
  • Data-driven mindset with strong analytical skills (Google Sheets, Excel, Seller Central reports, BI tools) to track KPI trends and identify whitespace opportunities
  • Cross-functional collaborator who works seamlessly with PPC, Content, and Operations teams
  • Clear, direct communicator with fluency in English
  • Comfortable wearing multiple hats in a fast-paced, small-team environment
Preferred:
  • Deep expertise in Seller Central; Vendor Central experience
  • Experience managing multi-brand portfolios in an agency environment
  • Familiarity with Walmart Marketplace, Target Plus, or other third-party channels
  • Exposure to Amazon DSP or Sponsored Ads campaign management
  • Experience with project management tools such as Asana, Monday.com, or equivalent
  • Comfort working in AI-assisted workflows and a willingness to adopt emerging automation tools

 You’ll be based in Symphony Towers, one of San Diego’s premier office spaces that offers:
  • Stunning views of the city and coastline
  • Free access to the building gym
  • Discounts at restaurants and cafes in the tower
  • Secure bike racks in the building and 24/7 paid parking in a nearby downtown structure
  • Close walking distance to 100+ of the top bars, restaurants, and coffee shops

Our office is designed for comfort, productivity, and collaboration, featuring:
  • Ergonomic standing desks and high-quality workstations
  • A fully stocked snack bar, espresso machine, and cold drinks
  • A welcoming team lounge area and sunny workspaces
  • A clean, modern space where we can do our best work together

Benefits & Perks
Our people are our #1 priority. Our benefits include:
  • Multiple medical plan options through Anthem Blue Cross
  • Dental & vision insurance (including orthodontia and annual exams)
  • Pet benefit program with savings on vet care, products, and services
  • Paid vacation (accruing up to 120+ hours/year with rollover and cap)
  • Paid holidays annually
  • Coverage for spouses/domestic partners and dependents under 26
  • Benefits begin on the first of the month after your hire date

Growth & Career Opportunities at Luminize
At Luminize, growth isn’t just something we drive for our clients; it’s our mindset and a big priority for our people.

We offer clear career paths and leveling guidelines so you always know where you stand, what’s next, and what skills and experience you need to get there. From day one, you’ll have visibility into advancement opportunities and what it takes to grow into leadership, specialization, or other cross-functional roles.

We’re proud of our strong track record of promoting from within. Many of our team leads and
managers started in independent contributor roles and grew by consistently showing initiative,
curiosity, and impact. We only hire externally when needed, because we believe the best future
leaders are often already here.

You’ll also benefit from:
  • Mentorship from experienced managers during 1:1s and annual performance reviews
  • Cross-functional exposure to departments including content, brand management, software, supply chain, operations, and catalog
  • Learning resources, including Udemy course access, and additional training programs and courses
  • A culture that encourages asking questions, trying new things, and leveling up together

If you’re excited to take ownership and grow, both in your craft and your career, you’ll be in good company here.
