Senior Frontend Product Engineer (React/TypeScript) - £80 -115K + Equity + Benefits

Hybrid (3 days/week in London)

The Opportunity

We're looking for senior product-focused engineers to help shape the future of our brand-new platform - one with zero tech debt, a strong engineering culture, and serious backing (pre-seed valuation: £25m).

This is a chance to have real ownership across product strategy, technical direction, and user experience, working closely with a tight-knit team of engineers who ship fast, think deeply, and care about craft.

We’re building a B2B SaaS Martech product that helps marketing teams drive growth with less guesswork. If you’ve worked on enterprise-grade products and love startup energy, you’ll fit right in.

What We’re Looking For

• Strong experience with React and TypeScript (Next.js a bonus)
• Solid engineering fundamentals and a product mindset
• Happy to work across the stack - ideally with Go (but if you’re fullstack in JS/Node/Express, with React on the front, we’ll teach you Go)
• Comfortable working in teams that own everything from design to deployment

A Bit About Us

We’re a 25-person team (11 engineers), growing steadily throughout 2025. Backed by top investors, we’re fast becoming one of Europe’s breakout startups. Our culture values autonomy, trust, and balance - and we’re serious about building a supportive, inclusive workplace.

Why Join Us?

• Generous equity (0.1%–0.3%) and top-percentile salary
• Visa sponsorship available (Skilled Worker/Tier 2)
• Latest MacBook and your own company card to get what you need
• Access to therapy, meditation apps & mental wellness perks
• Yearly retreats (sunny climates + a Christmas getaway)
• A cool London office + private gym access across the road
• We love new perk ideas – bring yours

Series A is on the horizon - this is your chance to join early and grow with us.
