From meal kits and ready-to-eat meals to specialty offerings like pet food and premium meat & seafood, HelloTech creates the platforms that bring tailored food solutions to millions of customers every month.\nOur subscription-based, direct-to-consumer model relies on technology at every step, from customer-facing apps and personalization logic to pricing, forecasting, supply chain optimization, and initiatives that help reduce food waste. While our brands operate independently to serve distinct customer needs, they are united by shared platforms, data, and operational excellence built by HelloTech.\nHelloTech works in autonomous, cross-functional alliances, each owning a specific product or domain end to end. By working with our Warsaw office, you will help shape scalable, data-driven products used across our markets, working with a modern tech stack and international teams to continuously improve how people discover, order, and enjoy HelloFresh’s products, today and in the future.\nAbout the role: What's in the Box\nYou will shape and scale the core mobile applications powering HelloFresh's brand portfolio globally, building high-performance, resilient experiences for millions of active customers across critical journey touch points - from menu discovery and basket building to automated subscriptions, payments, delivery tracking, and platform telemetry. Flexibility and cross-functional collaboration are central to how you will work; this evergreen role connects to squads across our Consumer, Platform, and Ordering alliances, where we partner with you to match your technical background, domain interests, and native platform depth (iOS/Android) with the team where you will drive the highest impact. You will leverage modern AI tools (Claude, Cursor, Copilot) across design, development, and testing as a force multiplier, actively lifting engineering velocity and product quality while solving complex customer problems end-to-end.\nAt HelloTech, flexibility and cross-functional collaboration are core to how we work. While this role is aligned to a specific Alliance, strong candidates may also be considered for opportunities across different teams or projects.\nWhat you’ll do: The Recipe\nArchitect, build, and optimize high-traffic, revenue-critical flows across our React Native iOS and Android apps, turning complex backend and GraphQL services into seamless customer experiences.\nRun data-driven experiments and A/B tests on high-impact surfaces, partnering closely with Product and Analytics to validate hypotheses and decide what ships next.\nDrive engineering excellence through robust automated testing across all layers, modular component architecture, and resilient release processes.\nDiagnose and resolve deep mobile challenges, including native module bridges, background syncing, memory management, and offline telemetry.\nTake end-to-end ownership beyond your primary specialization when solving critical user problems-treating your core discipline as an anchor, not a boundary.\nInstrument, monitor, and operate production systems to raise quality benchmarks across crash-free sessions, latency, retention, and conversion.\nElevate team-wide technical standards through RFCs, architecture reviews, workshops, pair programming, and collaborative mentorship.\nWork beyond your specialization when the problem demands it. Your specialization is your anchor, not your boundary.\nOperate what you build. You instrument, monitor, and improve your systems in production. Shipping is the beginning of the learning cycle, not the end\nWhat you’ll bring: The Ingredients \nHands-on experience working with AI tooling (e.g., Claude Code, Cursor, Copilot) beyond casual experimentation. You use AI agents every day. You have a practical sense of how the context you provide to AI tools shapes output quality, and how to set boundaries on AI-generated work.\nDemonstrated proficiency with modern AI development workflows (such as Claude Code, Cursor, or GitHub Copilot), with a clear grasp of prompt context and evaluating generated code boundaries.\nProven track record delivering production apps with React Native, TypeScript, and modern state management within a broader software engineering background.\nPractical insight into consumer-facing mobile applications at scale, balancing dependency trade-offs, on-device performance, and platform-specific UX patterns.\nStrong commitment to automated testing (unit, integration, and end-to-end) and robust mobile CI/CD deployment pipelines.\nSharp product sense and a bias for action, backed by the ability to articulate technical decisions and business trade-offs clearly using user evidence and metrics.\nCollaborative communication style that thrives when partnering across engineering, product management, design, and data disciplines.\nWorking familiarity with iOS (Swift/Objective-C), Android (Kotlin), federated GraphQL, web frontend tech, or experimentation platforms (such as Statsig or Optimizely) is a welcome plus.\nYou take full ownership. You have a bias to ship. You finish the last twenty percent. \nYou have product sense and are opinionated about what should be built and why, and you can back that opinion with data and user evidence.\nAbove all, we are looking for individuals who will make HelloFresh better. We believe there are many different ways of developing skills and we love diverse experiences! So even if you don’t “tick all the boxes” but think you’d thrive in this role, we would really like to learn more about you.\nWhat we offer: The Toppings\nGlobal collaboration at scale: Collaborate with experienced engineers and product partners across HelloTech’s international teams, in a culture of active knowledge sharing.\nTechnology with real-world impact: Build and operate modern systems at global scale, supporting 6+ millions of customers and complex supply chain operations.\nTechnical/Product/Design leadership: Drive best practices and influence architecture/design, quality, and ways of working in an autonomous, product-led setup.\nEnd-to-end development/delivery: Drive decisions from problem definition to production, improving systems and enabling long-term scalability.\n Access to workspace at Warsaw Centre Point. The hub offers modern facilities including showers, breakout zones, outdoor space, cycle parking, and refreshments (coffee, soft drinks, and fruit).\nAre you the missing ingredient? If this sounds like a tasty opportunity, we’d be excited to hear from you. We aim to review your profile and respond within 5 business days.","description_format":"text","description_chars":6739,"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":false,"industries":["Online Groceries","Subscription Commerce","Prepared Foods"],"lifecycle":[{"event":"open","at":"2026-11-12T12:27:52Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":42,"reasons":["conf:1","win:early","comp:brand"],"computed_at":"2026-11-12T20:46:06Z"},"pay":null,"html_url":"https://alion.io/job/hellofresh-senior-react-native-product-engineer","json_url":"https://alion.io/job/hellofresh-senior-react-native-product-engineer.json","meta":{"generated_at":"2026-11-12T20:46:06Z","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":43922,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":1061},"rest":"https://alion.io/mcp/rest/get_company?id=1061"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhellofresh-senior-react-native-product-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fhellofresh-senior-react-native-product-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fhellofresh-senior-react-native-product-engineer"},{"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/hellofresh-senior-react-native-product-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhellofresh-senior-react-native-product-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4161638}},{"tool":"search_jobs","arguments":{"company":"hellofresh.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4161638},"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.
