We guarantee 20% savings from day one by pooling cloud spend into a group-buying model. From there, our AI agent “Major Tom” acts like a virtual DevOps engineer, finding waste, optimizing infrastructure, all in an automated way to maximize cloud efficiency. We are building Blocks because startups deserve cloud economics that actually make sense.\nOur founders (Oliver and Andreas) are serial entrepreneurs, have raised >$1 billion, and successfully sold multiple businesses. \nYour role\nBuild the core user-facing experience, from responsive dashboards to onboarding flows\n\nDevelop and extend backend services in Python, implementing async endpoints, data flows, and internal APIs that power chat interactions, dashboards, and multi-tenant runtime operations\n\nDesign and integrate scalable APIs, connecting frontend, chat clients, and backend services to internal data layers and platforms\n\nShape intuitive product experiences from signup, onboarding, workspace management, to AI interactions\n\nCreate and maintain chat integrations (Slack) e.g. OAuth setup, slash commands, interactive modals, webhook flows, event-driven logic etc.\n\nCollaborate across engineering and product teams, aligning API contracts, improving platform features, and ensuring UX stays consistent as new features roll out\n\nImprove reliability and delivery workflows, contributing to CI/CD pipelines, frontend build optimizations, and quality checks that keep both web and chat clients fast and dependable\n\nWhat you bring\nFrontend experience: Strong experience with modern Typescript frameworks (e.g. React with NextJS), building responsive UIs with clean component architectures\n\nDeep expertise in Python: End-to-end systems with async patterns (DI/await/async ORM); modern web frameworks (e.g., FastAPI/Django/Flask)\n\nAPI integration expertise: Design/expose scalable APIs; handle AWS data/internal services with multi-tenant isolation/rate limits\n\nProduct and UX mindset: Comfortable crafting intuitive signup flows, onboarding experiences, and dashboards without a dedicated designer\n\nGreat to have: Practical experience shipping event-driven chat apps or bots (e.g., Slack Bolt SDK with OAuth, JS/TS integrations for Microsoft Teams etc.), including webhook processing and interactive UI flows\n\nStartup execution mindset: You have shipped 0→1 products fast with high ownership, autonomy, and accountability\n\nCurious, pragmatic problem solver: You experiment quickly, learn deeply, and optimize for impact over theory\n\nDirect communicator: You value clarity and feedback as tools for speed, improvement, and alignment\n\nDemonstrated impact: You have impressive achievements from previous jobs and from side projects. Please share them with us.\n\nWhat we offer\nBuild where AI actually matters. Real AI shipped into production that changes how companies run cloud infrastructure.\n\nWork with founders who’ve done it before. Unicorn builders, $1B+ raised, zero politics, fast calls, radical candor. We move, not debate.\n\nZero to One. The opportunity to build a product which startups will consider standard infrastructure.\n\nReal ownership, not theater. We challenge, you make calls. Some will be wrong. That’s fine. We fix fast and keep shipping.\n\nCompensation that reflects ambition. Top market cash compensation plus meaningful equity upside.\n\nBerlin, in person, by design. Early stage companies are built together, not on Zoom. We support relocation.\n\nHow we hire\nWe believe hiring should be like we build: Fast, respecting your time and ours, to the point: \nIntro call with a founding team member (30 min) \n\nTech interview/assessment with an engineer (~60 min)\n\nIn-person case study with the founders (1-2 hours)\n\nOffer call within 24 hours with a founder (15 min)\n\nIf you want comfort, this is not for you. If you want ownership and speed, we should talk.","description_format":"text","description_chars":3911,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-04T20:31:53Z"}],"visa":[],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.182,"p_room":0.28,"age_days":243,"expected_fill_days":22,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/blocks-senior-fullstack-engineer-mfd","json_url":"https://alion.io/job/blocks-senior-fullstack-engineer-mfd.json","meta":{"generated_at":"2026-10-13T22:25:02Z","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":34243,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":3894314},"rest":"https://alion.io/mcp/rest/get_company?id=3894314"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fblocks-senior-fullstack-engineer-mfd"},{"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%2Fblocks-senior-fullstack-engineer-mfd"},{"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%2Fblocks-senior-fullstack-engineer-mfd"},{"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/blocks-senior-fullstack-engineer-mfd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fblocks-senior-fullstack-engineer-mfd"}]}
