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 Team:\nBehavioral Data & Experimentation is a cross-functional platform team with end-to-end ownership of digital tracking across all markets globally at HelloFresh: from tracking infrastructure all the way to curated data products and the hypothesis validation mechanisms (e.g., A/B testing). Our customers are the engineering and product teams across HelloFresh, so reliability, automation, and developer experience are central to what we build. The squad brings together software engineers, data engineers, and data scientists to build the tracking, event, and statistical infrastructure that drives product decisions. Our work enables customer experience improvements and business growth.\nAbout the Role: What's in the Box\nAs a Senior Mobile Engineer, you'll own and evolve the mobile app tracking architecture that powers behavioral tracking and experimentation across HelloFresh's brand portfolio. Your core platforms are Android (Kotlin) and React Native. You will also contribute to iOS and Web codebases as the work requires, alongside teammates with deep expertise on those platforms. AI is part of our daily work: you'll use Claude, Zed, and Opencode across design, development, and testing, and help the team adopt new practices as they emerge. Above all, we want people who make the team stronger. Even if you do not meet every requirement, we would still like to hear from you.\nWhat you’ll do: The Recipe\nAt HelloFresh we are moving away from a model where software developers just execute tickets toward one where product engineers are trusted to own customer problems. A Product Engineer takes a problem, forms a point of view, validates it with customers and data, and ships it using AI as a force multiplier.\nOwn the integration and evolution of tracking and experimentation SDKs (Snowplow, Statsig, or equivalent) across Android native and React Native layers, ensuring consistent, reliable event capture for every brand and customer touchpoint.\nSolve native mobile telemetry challenges, such as lifecycle events, background sync, offline event buffering, and custom native bridges.\nEmbed AI-driven workflows into our platform tooling to increase automation and data quality.\nDrive engineering excellence by implementing robust automated testing, rigorous error handling, and high-quality release practices.\nWork closely with product managers, software and data engineers to continuously evolve our platform offering.\nMentor engineers and contribute to team-wide engineering standards.\nContribute to] the app experience, owning the metrics that reflect quality for mobile customers (retention, crash-free sessions, conversion).\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.\nExtensive mobile engineering experience (5+ years) with strong native depth, ideally on Android (Kotlin). If your depth is on another platform but you have a track record of ramping up quickly in unfamiliar stacks, that works for us.\nA flexible, cross-platform mindset, with a proven ability to work across mobile and web codebases.\nGenAI proficiency, including a proven ability to leverage AI tools and workflows to increase development speed, quality, and overall team output.\nA strong focus on engineering excellence, demonstrated through a commitment to high-quality codebases, proactive system stability, and resilient infrastructure design.\nExperience building and maintaining automated tests at different levels, including unit, integration, and end-to-end testing.\nA track record of taking ownership in ambiguous, cross-functional environments and working across engineering, product, and data teams to ship solutions that measurably move the needle.\nDeep mobile engineering expertise, with experience across the app release cycle, test automation, on-device performance and platform UX conventions.\nStrong communication skills, including the ability to explain technical decisions and trade-offs to different audiences.\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 people who will make HelloFresh better. 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.\nNice to have\nFamiliarity with how client-side signals flow into downstream systems such as GTM and Snowplow, and with A/B testing and feature-flagging frameworks such as Statsig.\nHands-on experience with iOS development (Swift).\nExperience with Web frontend development (React, TypeScript, browser telemetry).\nBasic backend or data engineering context (Node.js, Python, REST/gRPC APIs, or data pipelines).\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":7605,"description_truncated":false,"requirements":{"experience_years_min":5,"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":"2026-09-10T13:30:29Z"}],"visa":[],"liveness":{"score":32,"band":"fade","label":"Fading","p_open":1,"p_active":0.726,"p_room":0.44,"age_days":48,"expected_fill_days":40,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/hellofresh-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders","json_url":"https://alion.io/job/hellofresh-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders.json","meta":{"generated_at":"2026-10-21T10:48:47Z","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":15279,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":1061},"rest":"https://alion.io/mcp/rest/get_company?id=1061"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhellofresh-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders"},{"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%2Fhellofresh-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders"},{"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%2Fhellofresh-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders"},{"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-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhellofresh-dev-senior-mobile-product-engineer-intelligent-platforms-all-genders"}]}
