Senior Front-End Engineer (React) - Personalization

In a nutshell

• At Picnic, we're revolutionising the way people buy groceries with our affordable and sustainable grocery service. In the Personalization team, you’ll build the experimentation platform that lets Picnic try new ideas safely and at scale: from which promotions to highlight to which emails to send. Your work lets business teams run experiments and control the customer experience themselves, without needing an engineer for every change. It’s a product that is foundational to our business, and it directly improves how customers shop every day.
• We use React, React Native and TypeScript across the board, together with our server-driven UI framework , and we’re working towards a single platform for mobile and web.

Tricks of the trade

Think like a product owner. You don’t just implement requirements, you question them. Together with product owners and designers, you shape specifications for new features, discuss trade-offs, push back when something doesn’t add up, and help build a long-term vision for where the platform should go.

Build bridges. You work with cross-functional teams across the whole business: the business teams who rely on the platform, fellow engineers, and the other consumer-facing teams whose features run through it. You make it easy for others to succeed.

Drive things forward. You don’t wait for someone to hand you the next task. You spot what could be better, in the codebase, the platform or how the team works, and you take the lead on fixing it. You’ll take on increasingly challenging projects with full ownership of your contributions.

Our Tech: React, React Native, TypeScript and RxJS, Redux, Styled Components, Jest, Storybook

If you want ownership, real influence on product direction, and to see your work reach millions of customers, you’ll feel at home here.

We’re looking for

7+ years of building and shipping frontend applications end-to-end. You’ve taken products from idea to millions of users, and you’ve stayed around to make them better.

A strong conceptual thinker. You thrive in ambiguity and lead the way to the right solution.

Sharp judgement on trade-offs. You know when to build it right and when to ship it now, and you make that call yourself.

Real curiosity about the customer. You care whether your work changes how people shop, not just whether the code is clean.

Clear, structured communicator. You collaborate effectively with product, design, backend, analytics, and frontend teams.

Genuine motivation to build consumer and e-commerce experiences used by millions, with willingness to work from Picnic’s Amsterdam office-first environment .
