About Us
We are a fast-growing retail business based in North London, specialising in multi-channel online sales and eager to scale our ecommerce presence. We are seeking an experienced and proactive Senior eCommerce Sales Manager to join us in-house full-time and elevate performance across all platforms.
The Role
As our Senior E-Commerce Sales Manager (Multi-Marketplace Experience, you will take ownership of our entire online retail ecosystem. We operate across multiple online marketplaces, currently including Amazon, eBay, TikTok Shop, Shopify, B&Q, Wayfair, ManoMano, OnBuy, Etsy, and other emerging retail platforms. You don’t need experience with all of them, but the more of these platforms you’ve actively managed, the stronger your application will be.
Experience across several marketplaces and a clear understanding of how to diversify sales beyond Amazon will be key to success in this role. Your goal is to optimize each marketplace to reach its highest potential, continually driving sales growth and maximizing revenue.
You won’t be working alone. This role involves collaborating closely with an existing in-house and remote team. The successful candidate will guide, instruct, and coordinate with other staff members responsible for listings, design, and customer service to ensure all marketplaces run smoothly and consistently. The focus is on team leadership and process coordination, not single-handed execution.
In addition, you will be responsible for setting and delivering clear sales targets across all online channels, ensuring that revenue growth remains at the core of your strategy while balancing operational efficiency.
We work as a tight-knit, collaborative team, so strong communication and the ability to lead others will be key to success.
This role is pivotal in freeing the CEO to focus on product sourcing and wider business strategy, ensuring that commercial growth and operations are fully aligned.
Key Responsibilities
* Set and deliver monthly/quarterly sales targets.
* Lead advertising/promotional budgets for ROI with CEO approval on monthly spend, ensuring efficient use of budget and avoiding unnecessary subscription costs.
* Provide regular reporting to the CEO.
* Lead and manage day-to-day operations across multiple ecommerce platforms, ensuring each channel performs at its best while meeting agreed sales targets and revenue goals.
* Build, manage, and optimise listings, campaigns, and promotions across 10–12 online marketplaces (e.g., Amazon, eBay, TikTok Shop, Shopify, Etsy, Wayfair, ManoMano, OnBuy, B&Q, etc.), tailoring strategy to suit each platform’s customer base and sales potential.
* Work collaboratively with the wider e-commerce and operations team, providing clear direction, setting priorities, and delegating platform-specific tasks to ensure efficient teamwork and timely delivery across all channels.
* Strategise and implement growth initiatives tailored to different marketplaces, adapting to platform trends and consumer behaviour with a focus on maximising sales performance.
* Drive innovation in product listings—enhancing copy, images, pricing, and promotions to boost visibility and conversion and directly increase sales outcomes.
* Negotiate with platform partners (Amazon, eBay, TikTok etc.) to take advantage of advertising, premium placement, and promotional tools to deliver measurable sales uplift.
* Stay ahead of trends, platform policy changes, and competitive activity to ensure continuous improvement in online strategy and achievement of revenue growth targets.
What We’re Looking For
* Proven experience managing multiple ecommerce platforms, ideally across several of the following: Amazon, eBay, TikTok Shop, Shopify, Etsy, OnBuy, Wayfair, ManoMano, and B&Q. You don’t need experience in all of them, but a broad, multi-marketplace background will be highly advantageous.
* Note: Candidates do not need experience in every platform listed, but the more marketplaces you’ve actively managed, the better. We’re especially interested in applicants who can demonstrate success across a range of online sales channels, not just Amazon.
* Self-motivated, results-oriented, and adaptable to fast-paced environments, and excited by the challenge of scaling a business almost as if it were their own brand.
* Proven ability to lead sales strategy, deliver against revenue targets, and manage operations.
* A demonstrable track record of scaling online sales, supported by metrics or success stories showing achievement against sales targets.
* Strong analytical capabilities to interpret platform data, metrics, and ROI, with a strategic mindset on how to act on insights.
* Creative flair and attention to detail for optimizing listings, drafting persuasive copy, and running promotions.
* Excellent communication and collaboration skills for working effectively across departments.
* A natural team leader who can coordinate, train, and motivate colleagues, guiding them in marketplace operations rather than doing everything alone.
* Experience managing and developing junior team members, including providing clear guidance and direction to ensure they follow processes and contribute effectively to business goals.
What’s on Offer
* In addition, this role is framed as an entrepreneurial opportunity. The successful candidate will join at a pivotal stage, helping to design and shape growth strategies, and will have the freedom to bring fresh ideas and test creative approaches.
* Competitive base salary.
* Company pension scheme.
* Staff discount on products.
* Full-time, 37.5 hrs/week, office-based flexitime with core hours 10:00–16:00 hrs and early-finish Fridays supported.
* A highly visible position with real impact on our growth trajectory, playing a key role in our expansion strategy, with clear opportunities to step up into senior leadership as the company scales.
* Ongoing professional development, including external training and support to enhance your e-commerce expertise.
* For the first three months, the role will be on an agreed base salary with a focus on proving results. After this initial period, commission and incentives will be tailored in discussion with the successful candidate. This flexible approach ensures the package can be shaped around proven results and entrepreneurial drive.
* You’ll have structured onboarding and practical support from an experienced team member, so you won’t be doing it alone
