Senior Fullstack Engineer (FE-focused) — Monetisation Team (f/m/d)

About us

Pet Media Group (PMG) is a scale-up that acquires, launches, and develops market-leading pet marketplaces globally, with over 1.5 million animals finding new homes through our platforms every year. We currently operate in 6 countries (UK, Sweden, Netherlands, Italy, Spain, and most recently the US) — all within just 5 years of launching. Here's one of our apps: Pets4Homes.co.uk
The way pets find new loving homes has remained largely unchanged for centuries. We're on a mission to change that through innovative technology — and increasingly, through the intelligent use of AI. We're a young and ambitious team who have built unicorns before (e.g. Avito), backed by some of Europe's leading investors (e.g. Verdane and Otiva — early backers of Klarna, CAIA, Apotea, and Easypark).

Who are we looking for?

We're expanding our Monetisation team and looking for an FE-focused full stack engineer to help us build great products in the payment processing & value-added services space, and improve the user experience in the payment domain.
We're not just looking for a strong engineer — we're looking for someone who actively uses AI tools as part of their daily workflow: whether that's using LLMs to accelerate development, exploring AI-powered tooling for testing, code review, or product ideation, or simply staying genuinely curious about where the technology is heading.
We expect roughly 6 years of engineering experience, ideally with our current tech stack — and a mindset that sees AI as a multiplier, not a buzzword.

Requirements

We're a fast-growing scale-up. We want engineers who build fast, fail fast, and learn fast. You don't need to be a world-class expert in every tool we use — but you do need a critical, open mindset, strong JavaScript proficiency, and a genuine enthusiasm for AI-assisted development.
Core (required):

• Building apps with TypeScript, Next.js, Node.js & React

• Understanding of GraphQL and its usage in large systems with multiple consumers

• Experience with frontend testing tools and testing strategies

• Experience with relational databases like PostgreSQL

• Active use of AI tools (e.g. Claude, Cursor, Codex, ...) in your day-to-day engineering work — we want to hear how you use them

• Experience with payment processing (Stripe, Adyen, Braintree)

• Experience with search technologies like Elasticsearch

• Experience with monitoring & observability tools like Grafana

• Experience with responsive design & mobile web UX

• Experience with UI/component frameworks like Tailwind

• Experience evaluating or experimenting with AI coding workflows at team or company level
