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.\nWe 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. \nTricks of the trade\nThink 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.\nBuild 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.\nDrive 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.\nOur Tech: React, React Native, TypeScript and RxJS, Redux, Styled Components, Jest, Storybook\nIf you want ownership, real influence on product direction, and to see your work reach millions of customers, you’ll feel at home here.\nWe’re looking for\n7+ 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.\nA strong conceptual thinker. You thrive in ambiguity and lead the way to the right solution.\nSharp judgement on trade-offs. You know when to build it right and when to ship it now, and you make that call yourself.\nReal curiosity about the customer. You care whether your work changes how people shop, not just whether the code is clean.\nClear, structured communicator. You collaborate effectively with product, design, backend, analytics, and frontend teams.\nGenuine motivation to build consumer and e-commerce experiences used by millions, with willingness to work from Picnic’s Amsterdam office-first environment.\nPicnic Perks\nEvery expert was once a beginner! \nYou’ll get plenty of opportunities to challenge yourself and grow, including the Picnic Tech Academy, Lunch & Learn sessions, and tailored soft skills training. We also offer free professional weekly language courses.\nMake a difference\nYou’ll work in an awesome startup environment with the freedom to drive your own projects and create a visible impact. Our fully electric vehicles and sustainable business model mean you’ll also be contributing to making the world a better place! \nTeamwork makes the dream work\nWith more than 80 nationalities across 3 countries, you’ll be part of a diverse company with plenty of cool stuff to get involved with, from board game evenings to after-work drinks to our company ski trip and more!\nYou are what you eat\nYou’ll get freshly prepared, healthy lunches and snacks (with plenty of vegetarian, vegan, and halal options). Coffee snob? Don’t worry, our amazing Picnic barista has you covered.\nStay healthy \nMental health is important. As well as having the option to speak with Picnic colleagues who act as confidential advisors, our collaboration with OpenUp gives you easy access to professional psychologists, along with workshops and materials. \nThere are plenty of sports communities and events to get involved with, from tennis to yoga, to climbing! \nAttractive package\nWe offer competitive compensation and a pension plan that looks out for your future self, as well as 25 vacation days per year, so you can recharge your batteries \nBenefits for expats \nIt can be daunting starting a new job AND moving to a new country. That’s why we offer lots of support for our many expat colleagues, if you want to find our relocation benefits, see here.","description_format":"text","description_chars":4357,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Online Groceries"],"lifecycle":[{"event":"open","at":"2026-10-27T13:40:12Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":3,"expected_fill_days":62,"reasons":["conf:0","stale_co","velocity","win:early","comp:brand"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/picnic-senior-front-end-engineer-react-personalization","json_url":"https://alion.io/job/picnic-senior-front-end-engineer-react-personalization.json","meta":{"generated_at":"2026-10-31T11:22:26Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":17445,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":39193},"rest":"https://alion.io/mcp/rest/get_company?id=39193"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpicnic-senior-front-end-engineer-react-personalization"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fpicnic-senior-front-end-engineer-react-personalization"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fpicnic-senior-front-end-engineer-react-personalization"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/picnic-senior-front-end-engineer-react-personalization\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpicnic-senior-front-end-engineer-react-personalization"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3335687}},{"tool":"search_jobs","arguments":{"company":"picnic.app","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3335687},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
