Artificial Intelligence Engineer

Founding AI Engineer, Marketing AI, Remote (UK/Spain), Up to £100 000 + Equity

Do you thrive in early‑stage startups and love turning bold ideas into reality? Fancy building something from the ground up that reimagines how marketing emails are created, designed and sent, all in seconds? Our client is on a mission to let AI handle every step of the email campaign journey, and they need a Founding AI Engineer to help make it happen.

About them

They’re backed by one of Europe’s best‑known fellowships, a programme that’s already spawned unicorns. Over the past year they’ve built a prototype platform capable of sending ultra‑personalised email campaigns with almost zero user input. Valued at $5 million (pre‑seed), they aim to double that by their next raise in September.

What you’ll bring

• Hands‑on experience taking an AI startup from zero to one
• Solid track record developing, training and deploying NLP models, think BERT and classic pre‑LLM techniques
• Expertise with cutting‑edge LLMs and fine‑tuning, including OpenAI GPT, Anthropic Claude, LLaMA and the like
• Experience building multi‑agent systems

Bonus points

• Background in email marketing
• Experience generating synthetic data

We’re looking for someone with real entrepreneurial drive, grit and a builder’s mindset, who can move fast, deliver prototypes and learn on the fly.

What’s on offer

• Up to £100 000 base salary plus meaningful equity
• Fully remote, with a preference for London‑ or Barcelona‑based candidates to join an emerging hub in Barcelona
