What we're looking for
We're looking for an AI-first B2B Marketing Manager — a generalist — to help us scale our commercial engine across product marketing, content, events, outbound, and partner marketing.

You'll help build the operating system powering the next evolution of group training, working with partners like HYROX, Jetts UK, Huawei, FÔLD and pliability.

The Role
You'll work directly with the Head of Marketing to help build a scalable B2B marketing function that drives awareness, generates pipeline, and supports commercial growth.

You'll sit across:

• Product Marketing
• LinkedIn and thought leadership
• AI-assisted outbound
• Event marketing
• Sales enablement
• Partner marketing
• CRM and nurture flows

You'll help turn ONE FIIT from a fast-growing fitness technology company into a category-defining platform.

• ONE FIIT Operating System — Workout Builder, Multi Screen Delivery, Virtual Classes, Embedded App, Education Portal

Develop one-pagers, decks, case studies, and sales materials

Support website and conversion optimisation projects

Content & Thought Leadership
Run and grow ONE FIIT's B2B LinkedIn presence

Support major industry events including HFA, FIBO, Fitness Technology Summit, and ATN Innovation Summit

Coordinate launch support for partners

Create co-marketing assets and campaigns

Help run operator site visits and demos

CRM & Marketing Operations
Build email nurture flows

Maintain CRM hygiene and reporting

Help implement scalable marketing systems

Use AI tools to improve efficiency across workflows

Who you are
You might come from B2B SaaS, fitness tech, startup marketing, product marketing, growth marketing, or a hybrid / generalist background.

More important than your exact experience: you're curious, proactive, commercially minded, and excited by AI.

We'd love if you have

• Strong writing and storytelling skills
• Experience creating B2B marketing assets
• Understanding of LinkedIn and founder-led marketing
• Familiarity with AI tools like ChatGPT, Claude, Clay, Notion AI, etc.
• Experience working cross-functionally with sales and product teams
• A bias toward action and experimentation
• Interest in fitness, wellness, or technology

Bonus points

• Experience with HubSpot
• Experience in fitness, SaaS, or consumer apps
• Familiarity with AI SDR workflows
• Event marketing experience

What success looks like
Within 6–12 months, you will have helped:

• Build a repeatable MQL engine
• Scale ONE FIIT's thought leadership presence
• Improve demo generation
• Launch scalable outbound systems
• Support major product launches and partnerships
• Help define the category narrative for connected group training

• Grit to deliver — startup life is a rollercoaster; you'll execute at pace and take accountability.

• Equity / employee share scheme
• Private health & dental insurance with Bupa
• £1,000 annual personal development budget
• Flexible holiday and working arrangements

• Team workouts, team building days, and occasional offsites in places like Lisbon
• Inspiring office at Here East campus, Queen Elizabeth Olympic Park

Why join ONE FIIT?

You'll work with global brands, shape a growing category, and help build the systems behind some of the most exciting training experiences in the industry.
