We are building the future of scheduling and productivity. We work on hard problems at the meeting point of human collaboration and digital efficiency. We craft elegant solutions to complex problems, and we are looking for passionate problem solvers who share this drive.\nYou are a proactive builder and a continuous learner. You thrive on shipping products that matter. You always find a way to reach the goal.\nThe Role\nIn this role, you'll drive growth through experimentation. You'll turn ideas into hypotheses, ship experiments fast, read the results, and build more of what works for our users and our business. You'll own features end to end, from the backend to the user interface. Our newer frontends run on React.js, Next.js and TypeScript, wired to our platform through GraphQL and Apollo Client, on top of a polyglot ecosystem of Java and Go services built on Kafka. Some older apps still run on JavaScript, Redux and webpack, and you'll work in those too. We run experiments in GrowthBook, define our tracking events in Avo, and handle billing with Chargebee.\nWhether your background is frontend or fullstack, we care most about mindset. With AI in your toolkit, you are ready to work on anything: you'll follow a problem wherever it lives in the stack and solve it in the right place. If you get excited by A/B tests, funnels, and the exact precision needed when you build products around Time itself, you'll find a stimulating environment here.\nWe love high velocity, and AI is at the heart of how we build. We expect our engineers to use LLM and agentic tools (specs, agent loops, and agentic workflows) to iterate fast and build systems. We stay provider agnostic (Anthropic, OpenAI, Cursor, local models, or self hosted models in the cloud). We pair that speed with deep pride in ownership. A natural \"READ THE CODE\" mindset, where you keep a full understanding of, and full accountability for, every line you ship.\nWhat You'll Actually Do\nDrive Growth: Design, build, and run experiments across the user journey (acquisition, activation, conversion, retention) and turn the results into product decisions.\n\nOwn the Feature: Take ideas from hypothesis to production, end to end, wherever the work lives in the stack.\n\nShip with AI: Use LLM and agentic tools as your default way of working to move fast, while keeping total ownership and full understanding of the generated code.\n\nBuild the Frontend: Create fast, accessible, and scalable web applications with React.js, Next.js, and TypeScript.\n\nGo Beyond the Frontend: Extend backend services and GraphQL APIs when an experiment needs it, with Apollo Client managing data on the client.\n\nMeasure What Matters: Instrument features with clean tracking that respects each user's consent choices, so every test produces data the team can trust.\n\nOptimize for Speed: Tune performance for speed, scale, and smooth experiences across devices and platforms.\n\nTranslate the Hard Stuff: Work closely with product managers, UX designers, data analysts, and fellow engineers to turn complex scheduling requirements into clean, elegant solutions.\n\nWhat do you bring?\nYou'll thrive here if you are a builder who values customer impact as much as clean code, and who is happy to work on anything to reach the goal.\nThe Growth Experience: Proven, hands on experience with growth topics and product experimentation, such as A/B testing, funnel optimization, and activation or conversion work.\n\nThe AI Mindset: You are AI savvy. LLM and agentic tools are part of how you work every day, and you use them to deliver across the whole stack.\n\nThe Foundation: A Bachelor's in Computer Science, a related technical field, or equal practical experience.\n\nThe Toolkit: Professional experience with JavaScript, TypeScript, React.js, and Next.js, and comfort working in older JavaScript and Redux code.\n\nThe Data Layer: Experience building production ready applications with client side data fetching via GraphQL (Apollo).\n\nThe Fullstack Mindset: Frontend or fullstack, you are curious beyond your primary area, and you can read, debug, and change code across the stack.\n\nThe Location: You are based in Germany with full right to work. We cannot sponsor visas or support relocation at this time.\n\nNice to have:\nThe Backend Edge: Professional experience building backend services, ideally in Java, and designing GraphQL APIs.\n\nThe Distributed Layer: Practical experience with microservices and event driven architectures built on Kafka. Go is a plus.\n\nThe Data Craft: Comfort with experimentation platforms and feature flags such as GrowthBook, tracking plans such as Avo, product analytics, and the statistics behind a sound test.\n\nThe Billing Side: Experience with subscription billing and payments, ideally Chargebee.\n\nThe Architecture: A strong architectural mind for component isolation, server side rendering (SSR), and static site generation (SSG) strategies.\n\nThe Craft: Experience with frontend performance optimization, responsive design, and modern browser APIs.\n\nWhy Doodle?\nReal Impact: Your commits change how the world meets.\n\nTechnical Stretch: We deal with \"Time\" problems most companies never meet, from distributed, event driven services to the UX built on top of them. You'll learn how to build products around time zones, calendars and schedules that keep changing.\n\nMeasurable Impact: With millions of users, every experiment you ship shows its effect in real numbers.\n\nModern Tooling: We give you the best AI and agentic tools, and we expect you to use them.\n\nCulture of Trust: We value curiosity, autonomy, and a balance that respects your time as much as our users'.\n\nHiring Journey\nInitial Application Review\n\nTechnical Interview (based on Home Assignment)\n\nExec Interview\n\nHR Interview (BRYQ Assessment)\n\nFinal Offer & Reference Check\n\nAt Doodle, we're committed to providing an environment of mutual trust and respect, where equal employment opportunities (EEO) are available to all applicants and teammates without regard to age, race, color, disability, religion, gender, and sexual orientation. Diversity and inclusion are of utmost importance to us. We're committed to building a team that represents a variety of backgrounds, perspectives, and skills. The more inclusive we are, the better our work and our products will be. We want to hear from you, so please don't hesitate to apply! We look forward to receiving your full application.\nIMPORTANT NOTICE: Please note that we can only consider your application if you are based and have the right to work in Germany. At this time, we are unable to sponsor a visa for this position or support with relocation.","description_format":"text","description_chars":6784,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Scheduling & Booking Software"],"lifecycle":[{"event":"open","at":"2026-10-16T10:38:52Z"}],"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":96,"reasons":["conf:4","win:early"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/doodle-senior-software-engineer-fullstack-all-genders","json_url":"https://alion.io/job/doodle-senior-software-engineer-fullstack-all-genders.json","meta":{"generated_at":"2026-10-17T16:29:44Z","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":"assistant_verified","counted_by":"address","units_charged":1,"used_today":3065,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":54302},"rest":"https://alion.io/mcp/rest/get_company?id=54302"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fdoodle-senior-software-engineer-fullstack-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%2Fdoodle-senior-software-engineer-fullstack-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%2Fdoodle-senior-software-engineer-fullstack-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/doodle-senior-software-engineer-fullstack-all-genders\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fdoodle-senior-software-engineer-fullstack-all-genders"}]}
