ABOUT US

We are a mission-driven wellness brand with an award-winning range of collagen, blends and supplements. We started like all good businesses do, by seeing the opportunity to do things differently in a growing market. We carefully balance people, planet, and profit for the sake of the world around us and our health.

We are shaping the future of wellness with simple daily rituals, thoughtfully and sustainably designed to support women’s health. Our vision is to be the #1 wellness brand in the world, setting new standards for holistic health, sustainability and female empowerment.

As a B‑Corp, Ancient + Brave meets the highest standards of social and environmental impact. In June 2024 we were named 5th in The Sunday Times 100 fastest-growing private companies, and we have recently been recognized as one of the FT 1000: Europe’s Fastest Growing Companies, 2025.

Want to be part of a team that’s shaping the future of health and wellbeing? We’d love to have you!

THE ROLE

Deliver operational excellence and platform scalability across Amazon and additional marketplaces. Own all elements of listing quality, stock health, fulfilment performance, and marketplace expansion — ensuring commercial plans are enabled by operational precision and efficiency.

KEY RESPONSIBILITIES

• Own product catalogue health — accuracy, completeness, and policy compliance.
• Maintain high listing uptime and zero‑suppression standards.
• Implement content governance and version control for all SKUs.
• Monitor and resolve listing errors, suppressed ASINs, and stranded inventory.
• Lead stock forecasting and replenishment process in partnership with the Commercial Lead.
• Maximise stock availability and IPI performance; minimise OOS and excess inventory.
• Manage FBA/FBM mix to optimise cost, speed, and margin.
• Drive fulfilment efficiency and operational KPIs (on‑time delivery, defect rate).
• Build reporting infrastructure for listing health, stock coverage, and operational accuracy.
• Identify automation and process improvement opportunities to increase scalability.
• Partner with Commercial Lead to link operational data with trading performance.
• Lead onboarding and optimisation of additional marketplaces (eBay, Zalando, OnBuy, etc.).
• Develop scalable listing and stock processes to support multi‑channel growth.
• Standardise catalogue data architecture across platforms.
• Champion operational innovation — tooling, listing audits, and automation.
• Define best‑practice playbooks for product set‑up, marketplace launches, and issue resolution.
• Support category and product launch readiness from an operational perspective.
• Backend listing health score.
• Monitor health dashboard.
• Stock availability / OOS rate and IPI score.
• Operational accuracy (order defect, late dispatch, cancellation).
• Time‑to‑launch for new ASINs and new marketplaces.
• Automation / process efficiency metrics (time saved, accuracy uplift).
• Marketplace expansion milestones achieved.

• In‑Person Interview (60‑90 minutes): Final stage at our Lewes office. Meet with the hiring manager and one other team member and present your interview task and answer competency questions.

PLEASE NOTE

This role requires full‑time working at our stunning Lewes offices. Please apply only if you’re within a reasonable commute. There will be an option to work from home one day per week after successful completion of your probationary period.

We hold ourselves accountable to the highest standards when it comes to our commitment to balance profit and purpose. Working with us means being part of building a truly sustainable product. We are B Corp certified and members of 1% for the Planet, committed to giving back a portion of all sales towards helping environmental partners, so we can work together towards a better future for our planet.

At Ancient + Brave you’ll find an engaging, collaborative and inclusive work environment where your talents will be nurtured, and your contributions valued.

We provide all our team members with suitable laptop computers & headphones and our office is equipped with monitors, ergonomic chairs and sitting + standing desks. Our kitchen is fully stocked with the usual supplies as well as limitless supply of A+B products (you also get 50% off on any product you wish to purchase).

We pay a discretionary bonus based on a mix of company performance and individual contributions and review our salaries annually. Our pension contributions are ESG invested (so no pharma, weapons or other ethically questionable investments).

Our Private Medical Insurance is designed to support your health and wellbeing, providing swift access to high‑quality care whenever you need it most.

Our Medicash plan offers access to specialist consultations, 24/7 Virtual GP and health screenings as well as dental, optical and complementary therapies and access to confidential support via its EAP programme.

Our Mintago platform gives employees access to financial wellbeing advice and support as well as retail discounts and salary sacrifice schemes, which cover childcare, cycle to work, gym membership, groceries and mobile/tech purchase.

We offer continuous training & professional development opportunities and our team members get to enjoy complimentary nutrition and workout sessions in the office. We support a number of charities, coordinating our fund‑raising initiatives for maximum impact. We hold two social events a year to come together and connect in a meaningful way.

As a fast‑paced scale‑up, we’ve found that spending time together in person is hugely beneficial to the way we’re needing to communicate, collaborate and drive the business forward. We’ve worked hard to make our new HQ (a beautiful riverside office situated in Lewes, East Sussex) an inviting and friendly environment for all of our team members and we expect any new joiner to be in the office full time.

We are an equal‑opportunity employer committed to fostering an inclusive and diverse workplace culture. We embrace varied perspectives and encourage creativity that knows no bounds. While most of our roles are advertised as full‑time, we are open to discussing part‑time setup where appropriate.
