Fospha is the marketing measurement system for brands that sell everywhere. For over a decade, we've helped paid marketing teams see everything, sell anywhere and move instantly, so they can stop defending their budget and start growing it profitably.
Today's brands don't only sell on their own website. They sell through retailers like Sephora, Ulta and Amazon, and in physical stores. Fospha measures all of it, online and offline, from daily full-funnel attribution to planning, testing and AI-powered analysis. We've optimised over $40B in marketing spend, and we're scaling fast across London, Mumbai, and Austin.
This is a permanent, in-house role for a multi-disciplinary designer at the heart of Fospha's go-to-market motion. The work is deliberately varied: in a single week you might refine our website, design a sales asset for a major prospect, and extend our design system. We're looking for a versatile all-rounder with real depth across brand, web and presentation design, not a specialist in just one of them. You'll be the person who defines what "best in class" looks like for our brand, then makes it real: a dynamic, memorable website, standout sales and event materials, and a design system that lets the whole team move at pace without losing quality.
Your job is to make sure the imagery, motion and feel of Fospha land the pain points of our target enterprise brands as clearly as our words do, and to translate complex measurement concepts into visuals that are instantly easy to understand.
You'll sit in the Marketing team and work closely with Sales, Product Marketing, Product and our leadership. This is an office-based role: you'll be in the room for conversations on product, marketing and customer decks, so you deeply understand our customers, our product, and where and how we sell.
This role suits someone who loves ideation and is excited to work in a fast-paced, innovative startup environment.
Your time will be spread across four areas, so you'll have variety without losing focus.
Focus area What it covers High-value assets Ad hoc, high-impact pieces: sales materials, enterprise and keynote decks, event assets Fospha website and brand Front-end website design and maintenance, and the evolution of the Fospha brand Media partner website and brand Look and feel and web maintenance for Fospha’s media partner Design system on Claude Design Creating and maintaining the design system that lets us scale deck-creation and story-telling faster
