Senior Product Manager - Operations

Job Overview

As the Senior Product Manager for Operations at Mumzworld, you will be the architect of our "Post-Purchase" engine, with a particular focus on the Marketplace and Seller experience. You will own the technical ecosystem that manages the lifecycle of an order from the moment a seller lists a product, through onboarding, fulfillment, and payout, to the second it is reconciled in our financial books. This role is about building the "nervous system" of Mumzworld, including the Seller Center/Vendor Portal, OMS, WMS, and ERP.

Key Responsibilities

Seller Center & Marketplace Ops (Primary Focus): Own the Seller Portal / Vendor Portal end-to-end, seller onboarding flows, bulk catalog and listing management, seller-fulfilled (drop-ship) workflows, and the tools that empower our marketplace partners to operate independently and efficiently.

Seller Payouts, Commission & Reconciliation: Design and own the logic for seller payouts, commission/take-rate structures, and automated financial reconciliation between marketplace transactions and seller ledgers - ensuring accuracy, transparency, and timely settlement for partners.

Catalog & Listing Operations: Build and optimize the systems sellers use to list, update, and manage products at scale including bulk upload tools, catalog quality/compliance checks, and listing approval workflows.

ERP & Financial Integrity: Own the integration between physical/marketplace transactions and financial records. Ensure every order, return, seller payout, and lost item is accurately reflected in the ERP for automated reconciliation.

Fulfillment & WMS Strategy: Lead the roadmap for our Warehouse Management System. Optimize picking algorithms, inbound receiving, and inventory QC to ensure the highest throughput at the lowest cost.

Inventory & Multi-Node Orchestration: Design logic to manage stock across internal warehouses, 3PL partners, and seller-fulfilled inventory, minimizing split shipments and ensuring real-time "Available to Sell" accuracy.

Logistics & Last Mile: Lead technical integrations with regional carriers, focusing on delivery density, automated manifesting, and real-time tracking from dispatch to doorstep.

Reverse Logistics: Redesign the returns and refund experience, ensuring seamless communication between the warehouse QC team, the Seller Center, and the Finance ERP.

What We're Looking For

• 5+ Years in Product Management, with hands-on ownership of a Marketplace, Supplier Portal, or Vendor Portal product

• Marketplace Operations Expertise: Direct experience with seller onboarding, catalog/listing operations, seller-fulfilled workflows, and the operational mechanics of running a multi-seller marketplace.

• Payouts & Commission Structures: Demonstrated experience designing or managing seller payout systems, commission/take-rate models, and reconciliation between marketplace GMV and seller settlements.

• Subject Matter Expertise: Strong understanding of Seller Center/Vendor Portal platforms, with working knowledge of ERP (Finance/Inventory modules) and WMS as complementary systems.

• Demonstrated Ability: Translate complex operational pain points (such as seller onboarding friction, payout disputes, or catalog data quality issues) into scalable product solutions.

• Technical Depth: Proven experience with backend platforms and API integrations. Comfortable discussing how data flows from a seller's API into the marketplace platform, the OMS, and finally into the ERP.

• Analytical & BI Proficiency: Ability to analyze complex data to identify bottlenecks in seller onboarding, catalog operations, or leakages in payout/commission reconciliation.

• Track Record: Proven success driving measurable improvements in seller activation time, catalog quality, payout accuracy/timeliness, and take-rate optimization.

What Sets You Apart

• Deep marketplace/eCommerce experience: you've built and optimized seller-facing or vendor-facing products, not just buyer-facing ones

• Self-starter mentality: you don't need hand-holding or constant check-ins

• Bias for action: you move fast, make decisions, and avoid analysis paralysis

• Multi-tasking mastery: you can handle multiple high-priority projects simultaneously

• Results delivery: you have a proven "get things done" track record

The Right Fit Will:

• Take initiative and ownership

• Communicate proactively and keep stakeholders (including external sellers/vendors) informed

• Find creative solutions when faced with obstacles

• Prioritize ruthlessly and execute flawlessly

• Thrive in ambiguous, fast-paced environments

High-Impact Environment

• Direct influence on product strategy affecting millions of customers and thousands of marketplace sellers

• Fast-paced, entrepreneurial culture with significant growth opportunities

• Access to leadership and ability to shape company direction

Growth-Focused Culture

• Data-driven decision making with access to comprehensive analytics

• Collaborative environment with engineering, operations, finance, and seller/partner management teams

• Opportunity to build and scale marketplace products in a rapidly expanding market

Professional Development

• Work with cutting-edge marketplace and eCommerce technologies

• Exposure to regional market dynamics, seller ecosystems, and customer insights
