Ecommerce Manager in London

Listing Monster AI is a fast-growing software startup transforming the online resale industry. We’re building the operating system for resellers — a single platform to source, list, automate, and manage resale operations across multiple marketplaces. Since launching in 2023, we’ve grown rapidly and now partner with hundreds of resellers, from large charities to side-hustlers. This year alone, we’re on track to list over 2 million items.

Resale is uniquely complex: every item is different, workflows are manual, and profitability is constrained by time, space, and expertise. We remove these bottlenecks with an AI-first approach, enabling resellers to operate efficiently and scale profitably.

To support our next phase of growth, we’re launching our own in-house ecommerce trading operation. This operation will:

• Bring us closer to real customer workflows and challenges
• Generate thought leadership and customer education content
• Sharpen our product through live, real-world R&D
• Set the standard for best-in-class, data-driven resale operations

Role Overview:

Run the operation: You’ll own the day-to-day running of Listing Monster AI’s in-house ecommerce trading business, managing the full resale workflow — sourcing, photography, listing, merchandising, and dispatch — using Listing Monster AI as the core operating system.

Content creator: By operating at a high standard and sharing how the business runs across media channels, you’ll showcase AI-powered resale operations and position Listing Monster AI as the leading authority globally in the space.

Improve the product: You’ll sit at the intersection of live trading and product development, testing new features, spotting issues, and feeding clear, actionable insights back to the team to directly shape the future of the platform.

Build from scratch: This is a high-ownership role in a fast-moving environment, with real influence across operations, product, and marketing. You’ll help define how modern, AI-powered resale businesses are run.

• Manage the resale workflow end-to-end: (1) Source stock; (2) List products efficiently using Listing Monster AI’s platform; (3) Merchandise and manage active listings to maximise sell-through; (4) Run warehouse and dispatch processes.
• Work towards agreed targets: both operational and trading, and continuously optimise performance.
• Test new product features, workflows, and tools in a live trading environment.
• Provide clear, actionable feedback to the product and development teams.
• Adapt processes as the platform and operation evolve, helping to define best practice as you go.
