Founding Product Marketing Manager

London (Shoreditch) | Hybrid: 2–3 days per week in office | Up to £105,000

A growing B2B SaaS business is hiring a Founding Product Marketing Manager to establish and lead its product marketing function.

This is a high-impact IC role for someone who enjoys building from scratch: shaping product narratives, bringing launches to market, enabling commercial teams, and creating the foundations of a scalable PMM function.

What’s in it for you?

• Build a product marketing function from scratch




• Shape the company’s product launches, positioning, and sales enablement




• Work closely with senior marketing, product, and commercial leaders




• Potential to grow into people leadership as the marketing team expands

The role

Reporting to the CMO, you’ll work closely with Product, Sales, Customer Success, and senior leadership.

You will:

• Own product positioning, messaging, and go-to-market plans for product releases




• Partner with Product to turn roadmap updates into clear customer and commercial narratives




• Rebuild sales‑enablement materials, including battlecards and objection‑handling guides




• Map the buyer journey and ensure consistent messaging across each stage




• Develop competitor and market insight to inform positioning




• Build the processes, assets, and roadmap for product marketing as the function grows




• Present ideas clearly and gain buy-in across technical and commercial stakeholders

To be successful as the Product Marketing Manager, all you need to have is:

• 4+ years’ B2B Product marketing experience product within SaaS or tech




• Startup or scale-up experience, ideally having built PMM capability in an ambiguous environment




• PMM experience across two businesses, or a strong founding PMM background




• Commercially minded, hands‑on, and comfortable without an existing playbook




• Able to influence Sales, Product, and Customer Success teams

Join at a pivotal stage and define how a growing SaaS business takes its products to market – building a function, influencing senior leaders, and seeing your work make a visible commercial impact.
