We build fast and AI-first, so we look for builders. By a builder, we mean someone who turns \"maybe\" into \"done\".\nWe're looking for a Full-Stack Developer to join our squad and work on one of Lusha's core products, used by thousands of users across a large number of accounts, from enterprise companies to very small businesses. The role covers backend infrastructure as well as a significant frontend.\nOur group works deep inside data, beyond the classic full-stack and backend worlds. A large part of the group's responsibility involves data. There are no domain boundaries here: you'll work on a wide range of tasks and technologies.\nThis role is based in Tel Aviv. We work in a hybrid model, with 3 days a week in the office.\nThis might be for you if:\nYou don't just take tasks. You look at the product, care about it, and suggest how to improve it\nWhen you get a task, you talk to everyone you need to and own it end to end\nYou care about what happens after deployment: how users use what you built, how it's monitored, and what worked or didn't\nYou work agent-first: you run multiple AI models in parallel while staying hands-on and proactive\nYou've built or improved AI tools for your team that made real processes more efficient, beyond code review\nYou enjoy meeting users and making an impact on a large user base\nRequirements\n 4+ years of Full-Stack experience: You build and ship end-to-end features for production UIs, not just backend APIs.\nTypeScript & React Expert: Deep proficiency in TS on both client and server. Strong hands-on experience with modern React and state management (e.g., TanStack Query, Zustand).\nAI-Native Engineering: You build software \"agent-first.\" You leverage tools like Claude Code or Cursor daily, going beyond basic prompting to build MCP integrations, custom skills, and AI-driven workflows that multiply team velocity.\nBackend & API Architecture: Solid experience with Node.js (NestJS preferred) for building scalable microservices and robust APIs.\nData & Databases: Deep understanding of SQL and PostgreSQL, including schema design and query optimization at scale.\nTrue Production Ownership: You deploy your own code and actively use logs, monitoring, and product analytics to ensure system health and user success.\nNice to have\nBuilding AI product interfaces, such as streaming chat UIs or rendering agent output\nMicro-frontends, or building and publishing shared R versioning)\nDatabricks / Spark, or other large-scale data pipelines\nTemporal or other workflow orchestration\nKafka in production: partitioning, consumer groups, replays\nKubernetes, Docker and CI/CD\nObservability and analytics tools such as Coralogix and Amplitude","description_format":"text","description_chars":2727,"description_truncated":false,"requirements":{"experience_years_min":4,"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":["Sales Enablement","Lead Generation","B2B Company & Contact Data"],"lifecycle":[{"event":"open","at":"2026-10-18T14:12:42Z"}],"visa":[],"liveness":{"score":99,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.993,"p_room":1,"age_days":3,"expected_fill_days":21,"reasons":["conf:0","urgency","velocity","win:early"],"computed_at":"2026-10-22T06:10:10Z"},"pay":null,"html_url":"https://alion.io/job/lusha-full-stack-developer","json_url":"https://alion.io/job/lusha-full-stack-developer.json","meta":{"generated_at":"2026-10-22T15:18:01Z","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":14986,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":49222},"rest":"https://alion.io/mcp/rest/get_company?id=49222"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flusha-full-stack-developer"},{"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%2Flusha-full-stack-developer"},{"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%2Flusha-full-stack-developer"},{"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/lusha-full-stack-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flusha-full-stack-developer"}]}
