Job description

Operations Analyst · Marketplaces (Amazon MX and Mercado Libre)

Flay Industries · Mexico City (Colonia Juárez) · On site · Full time

Flay Industries builds and scales its own consumer brands from Mexico City for Amazon Mexico and Mercado Libre. We design the product, manufacture it with suppliers in China, import it and sell it ourselves. Our portfolio includes Landmark, one of the top-selling pillow and bedding brands on Amazon Mexico, plus Simply Active and Simply Her in wellness and SonicBurst in personal care. Four years in, more than 50,000 units sold and seven figures in USD sales a year, with no outside investors: we have grown with what the business generates. We run a lean team with no layers and an in-house AI system that handles pricing, advertising, replenishment and reporting. Every product starts from one question: what is the Mexican consumer missing that nobody delivers well?

The role

You will run the day-to-day operation and own the sales channels: inventory, shipments, the Amazon and Mercado Libre accounts, and everything coming from suppliers. You work directly with the founder, with the AI system as your analyst, and you bring numbers to every decision you escal​ate.

This is not a closed list of tasks. It is a growing business where what needs doing gets done, and where whoever shows judgment takes on more decisions.

What you will be exposed to

• Imports from China, start to finish: supplier follow-up, production, freight, customs and landed cost. You will see a product go from factory quote to Amazon listing.
• Pricing and promotions with real money on the line: reference prices, deals and coupons, Buy Box dynamics, FBA fee thresholds, and seasonal plans for Buen Fin and Hot Sale, measured in days.
• Agentic AI workflows: an in-house system of AI agents that runs pricing, advertising, replenishment and invoicing. You will learn to work with, supervise and improve agentic workflows, not just prompt a chatbot.
• Marketplace advertising with real budgets: weekly TACOS reviews and campaign changes, with the AI system doing the data work.
• The weekly P&L: units, fees, ad spend and contribution by SKU, read every week with the founder.

What you will own

• Inventory and replenishment: stock in FBA, at the warehouse and in transit; early stockout detection; weekly transfers to Amazon and Mercado Libre.
• Marketplace operations: catalog, listing health, cases with the platforms, Buy Box and reference-price issues, buyer messages and reviews resolved the same day.
• Imports: purchase orders, factory production, containers and documents with suppliers, freight forwarders and the customs broker.
• Pricing and promotions: analysis and proposals with numbers (profit per unit, per week, scenarios); execution on the platforms once approved.
• Advertising: weekly TACOS review and operational adjustments.
• Peak seasons: Buen Fin, Hot Sale and Prime Day ready on time: inventory, deals and ads.
• Weekly report: what happened, what it cost, and what we change next week.

Who we want

• 0 to 3 years of professional experience. Recent graduates welcome.
• A quantitative or analytical background: engineering (industrial, mechanical, systems, chemical or similar), actuarial science, economics, applied mathematics, business, accounting and finance, international business, or any degree where you worked with numbers.
• You think in numbers and in causes: you find the problem, size it in pesos, and propose the fix before anyone asks.
• Ownership: you close what you open. If a supplier or the warehouse does not answer, you find another way.
• Order and follow-through: nothing stays open, and a typo in a shipment costs money here.
• Advanced Excel or Google Sheets. (SQL or Python is a plus, not required.)
• No Amazon or Mercado Libre experience required; we teach that. We cannot teach how you think.
• Available during peak season: in Buen Fin or Hot Sale, an account with a problem does not wait until Monday.
• Spanish native, professional English. Based in Mexico City, on site in Colonia Juárez, Monday to Friday.

How you grow

First three months: learn the operation alongside the founder, with 90-day goals. From month four, the operation runs with you. From there, decisions are earned, not scheduled: whoever shows judgment with numbers proposes prices, promotions and ad spend, and takes on more.

What we offer

• Monthly net salary between MXN 25,000 and 30,000, depending on profile.
• Performance bonus.
• Direct work with the founder and real responsibility from day one.
• Start in November 2026.

The process is a 10-minute call, a 90-minute video session working a practical case as a team, and a decision the same week. We reply in every case.
