GTM Engineer

Are you the kind of person who gets excited about building systems and workflows?

Do you want to learn how modern GTM engines actually work — the tools, the data, the workflows — and then make them better?

Are you commercially hungry, technically curious, and genuinely excited about what GenAI can do for B2B marketing?

About us

Fospha is dedicated to building the world's most powerful measurement solution for online retail. For over a decade, we've helped teams make smarter decisions with full‑funnel marketing insights, forecasting, and optimisation. With Fospha, every team moves faster and grows smarter.

Trusted by leading brands across three continents, including Huel, Oh Polly, and Dyson, Fospha manages $4 billion in annual ad spend.

We're scaling fast across London, Mumbai, and Austin – and we're now looking for a GTM Engineer to join our Marketing team. You'll be responsible for building, running, and improving the activation layer that turns our marketing strategy into qualified pipeline — across ABM, outbound, inbound, events, and partner-led motions.

In addition to your core responsibilities, we expect you to be excited by the opportunity Gen AI brings and find new ways of working utilising our Gen AI hub!

What are we looking for?

We hire for potential and mindset. You should apply if you:

• Are technically curious — you love learning new tools, building workflows, and figuring out how systems connect
• Are commercially driven — you care about pipeline, revenue, and winning new business
• Are genuinely excited by GenAI — not just as a buzzword, but as something you actively use and want to build with (experience with tools like Claude, ChatGPT, Cursor, or similar is a strong signal)
• Have strong communication skills and are comfortable working across Marketing, Sales, Partnerships, and RevOps
• Are organised and data-literate — you track what works, learn from what doesn't, and iterate fast
• Want a role with real ownership and progression — this role can grow into senior positions across Growth, RevOps, GTM Strategy, or Sales

• Experience with GTM or marketing automation tools (e.g. HubSpot, Apollo, Dripify, or similar)
• Exposure to ABM, outbound, or demand generation in a B2B context
• Any experience building with AI tools — personal projects, automations, scripts, or internal tools
• Internship or early experience in growth, operations, or sales

Our Values and Principles

You will be able to demonstrate examples of our core principles:

• Seek inclusion & diversity: We create an environment where everyone feels welcome, and people are encouraged to speak and be heard
• Work Hard, Work Well, Work Together: We take responsibility for making things happen, independently and together; we help colleagues in need and close loops, making sure our work is complete and has lasting impact

• Candour with caring: We deliver candid feedback with kindness and receive it with gratitude
