Multi-Channel E-commerce Manager - Amazon, TIktok

Hypersonic Wholesale Ltd runs consumer brands across Amazon UK, TikTok Shop, Shopify, Temu and eBay, and is hiring a Multi-Channel E-commerce Manager to own the day-to-day running of every marketplace account. Immediate start.
You will be the single owner of account health, listings, compliance, cases and customer messages across all platforms, reporting directly to the founder. The core focus is Amazon and TikTok Shop, with Temu, Shopify and eBay alongside.

Key responsibilities
You own these across every platform unless stated otherwise.
Account health and compliance

• Monitor account health daily on every marketplace and act before metrics breach thresholds (Amazon AHR, ODR, late shipment; TikTok Shop response rate, LDR, violation points; eBay seller standards)
• Handle all policy notifications, violations, warnings and appeals, including drafting and submitting appeals with evidence
• Keep product compliance documentation current: ingredients, labelling, safety and certifications (particularly for pet treats and confectionery), plus any platform-specific compliance requirements such as GPSR, responsible person and category approvals
• Manage IP, brand registry and trademark matters on each platform

Case and dispute management

• Open, chase and resolve all seller support cases: listing errors, lost or damaged inventory, reimbursements, suppressed listings, account issues
• Keep a tracker of open cases with status and next action, and escalate to the founder only when a decision is needed

Listings and catalogue

• Create, upload and maintain product listings on every platform: titles, bullets, descriptions, A+ and brand content, images, variations, attributes and keywords
• Keep pricing, stock levels and promotions consistent across channels
• Set up new product launches end to end, including TikTok Shop product cards and affiliate samples
• Audit listings regularly for suppressed items, missing attributes and conversion issues, and fix them

Customer messages and reviews

• Answer all customer messages across every platform within platform SLAs (TikTok Shop and Amazon 24-hour response rate must stay above 90%)
• Manage returns, refunds, replacements and A-to-Z claims
• Monitor reviews and ratings, respond where appropriate and flag product or supplier issues

Inventory and fulfilment

• Create and manage FBA shipments, monitor inbound and stranded inventory, and flag reorder points
• Monitor TikTok Shop fulfilment and dispatch performance and coordinate with the warehouse team on any late orders

Advertising and promotions

• Day-to-day management of Amazon PPC and TikTok Shop ads campaigns: bids, budgets, negative keywords and reporting
• Set up deals, coupons, Prime Day and seasonal promotions across channels

Reporting and improvement

• Weekly report to the founder covering sales, account health, open cases, ad spend and what you changed
• Proactively bring ideas for improving sales, efficiency and account health, including how AI tools can automate or speed up the work
• Document SOPs for recurring tasks so processes do not live in one person's head

Must have

• 2+ years hands-on experience managing an Amazon Seller Central account (FBA), including listings, cases, account health and PPC
• 1+ years hands-on experience managing a TikTok Shop seller account, including Seller Center, Shop Chat, affiliate and campaign tools
• Completed relevant training in Amazon and TikTok Shop selling (please list courses or certifications in your application)
• Previous customer service experience, handling customer messages, complaints and returns to a deadline
• Working knowledge of Shopify, eBay and Temu seller tools, or the ability to pick them up fast
• Confident with AI tools (ChatGPT, Claude, Gemini or similar) for drafting listings, replies, appeals and SOPs, and able to suggest where AI can improve how we work
• Takes initiative: spots problems before being told, fixes what can be fixed, and comes to the founder with options rather than questions
• Highly organised with a tracker for everything, strong written English, and comfortable working remotely with minimal supervision
• Available to start immediately

Nice to have

• Graphic design ability (Canva, Photoshop or AI image tools) for listing images, A+ content and TikTok Shop assets
• Experience in pet, food or confectionery categories, or with regulated product compliance
• Experience with Amazon Brand Registry, IP complaints and trademark matters
• Experience with Amazon Ads or TikTok Ads beyond basic campaign management
• Familiarity with GoHighLevel, Notion or similar tools

Hours and availability
This is a full-time role: 40 hours per week, Monday to Friday, 8 hours per day within UK business hours (approximately 9am to 5pm UK time), with a short daily inbox check in the morning so no customer message waits overnight.
Weekends: Marketplace SLAs run seven days a week. We ask for a brief check of customer messages and account notifications once on Saturday and once on Sunday (typically 15 to 30 minutes) to answer anything urgent. This is a light-touch commitment and will be reflected in the salary.

Communication: Daily end-of-day update in Slack or WhatsApp, weekly report and call with the founder.
