Mid/Senior Performance Marketing Specialist

Job Summary:

At Bison Commerce, we are building a profit-focused, data-driven growth engine that sells products across multiple US-based eCommerce channels. As we expand our advertising investment, we are looking for a Senior Performance Marketing Specialist to take ownership of campaign execution, performance, and scaling.

In this role, you will own paid media execution across our growing US ecommerce portfolio - managing PPC across a multi-channel US ecommerce portfolio with hundreds of SKUs, with a strict mandate to scale spend profitably, not just spend more. The majority of your day-to-day work will focus on Amazon Ads, where the bulk of our advertising investment lives today, with potential expansion into other US ecommerce channels (Walmart, Meta, and others) as the business grows. You will apply structured testing, bidding, and campaign logic to identify what works, what does not, and where to invest further.

We are not looking for someone learning paid media - we are looking for someone who has already managed significant ad budgets at scale and brings frameworks for scaling profitably. Amazon-specific mechanics can be learned internally, but strong scaling instincts and structured performance execution are expected from day one.

You will work closely with internal teams on product, pricing, and content to ensure advertising aligns with overall product performance and business goals. Based on performance data, you will make clear, data-backed decisions on when to scale, optimize, defend, or stop campaigns.

This position is ideal for someone who understands performance marketing at scale, executes with ownership, and is motivated by improving results through structured, repeatable execution in a high-volume environment.

Key Responsibilities:

• Own day-to-day execution and optimization of PPC campaigns across a large Amazon SKU portfolio.
• Build and refine scalable PPC frameworks, including bidding logic, campaign architecture, and testing protocols across large SKU portfolios.
• Manage day-to-day campaign execution, budget allocation, search term coverage, and scaling decisions based on performance, profitability, and business priorities.
• Own the PPC P&L: forecast spend, ROAS, and incremental contribution; report directly on business impact.
• Monitor product and portfolio performance beyond ad metrics alone, identifying where to scale, improve efficiency, defend profitable products, or stop investing based on overall business impact and long-term potential.
• Work closely with internal teams on pricing, promotions, product content, and catalog readiness to improve advertising performance and conversion.

Qualifications:

• 4+ years of hands-on experience managing PPC or performance marketing campaigns at scale.
• Strong understanding of paid media fundamentals: bidding, budget allocation, scaling, testing, and performance optimization.
• Track record of scaling spend while maintaining or improving profitability (ROAS / contribution margin).
• Proven experience managing and scaling paid media budgets of at least $30,000/month.
• Experience managing multiple campaigns or complex account structures.
• Ability to analyze performance data and make clear, confident decisions based on it.
• Structured way of working with strong attention to detail and ability to prioritize in high-volume environments.
• Fluency in written and spoken English.

Nice to have:

• Amazon Ads experience. We value proven experience scaling paid media across any major channel (Google Ads, Meta, TikTok, etc.) - Amazon-specific knowledge is a plus, not a requirement.
• Experience in building own analysis frameworks - comfortable working with raw data in Excel, BI tools.
