Full Stack Engineer - Growth & Marketing

If this excites you, we might just have the role for you.

🧐 You will be responsible for:

• Growth and marketing engineering - build and evolve the technical foundations that support customer acquisition, activation, and retention across Treatwell's markets
• Discoverability - improve how search engines and users understand Treatwell's marketplace, without turning the role into a pure SEO implementation function
• Experimentation and measurement - instrument your work, support testing frameworks, and help teams validate ideas with data before scaling them
• Product surfaces - ship user-facing improvements to landing pages, discovery journeys, and conversion flows, owning the work from problem framing through production
• Platform quality - own your services end-to-end, from architecture through deployment, with a DevOps mindset baked in
• Cross-functional clarity - translate growth and marketing opportunities into clear engineering work, challenge scope when needed, and keep quality standards high

🔝 About you:

• You have proven experience owning production-grade web applications end-to-end, and understand that the best technical decisions come from deeply understanding the problem - not just the code (mid/senior level)
• You own features end-to-end - from database schema to UI, without needing a handoff
• You think in systems and trade-offs, not just tickets - you spot the upstream cause, not just the downstream symptom
• You have a product mindset - you think about the person using what you build, ask why before how, and push back when something doesn't make sense
• You're data-driven and hypothesis-led - you instrument your work, measure impact, and use evidence to make decisions
• You can partner with non-engineering stakeholders, turning ambiguous growth or marketing needs into sensible technical options
• You will act as the key technical partner for marketing stakeholders, evaluating the feasibility of their requests, managing expectations, and finding the right trade-off between business speed and technical quality (TBC).
• You are able to make progress in evolving or complex domains while collaborating to create clarity - growth work often moves fast, and you know how to navigate that without getting paralysed
• Experience with SEO, experimentation, analytics, performance, or growth-related product areas is a plus
• Experience with AI-assisted development tools such as Claude, Cursor, or similar - and clear opinions about where they genuinely add value is a plus
• You can communicate fluently in English.
• You are based in any city within Italy or Spain, with a valid right to work - candidates outside of these countries will not be considered.

NOTE: If you don't meet every requirement but believe you'd thrive in this role, we'd still love to hear from you.

💼 We’ll treat you with:

• 28-days holiday, plus bank holidays 🏖️
• Monthly £/€40 Treatwell vouchers so you can treat yourself too 💅🏻
• Mental health support through our partnership with Open-Up 🧘🏻
• 100% remote position 🧑🏻‍💻
• Market-specific benefits that will be discussed in the interview process
