But make no mistake - software development is just a part of what we do at Startup House. Our mission is to deliver all-around support for growing companies.\n\nOur Development Team is expanding and looking for fresh blood - we’re currently looking for a Senior AI Native Developer, who will help us build amazing products for our clients. As we grow, we're expanding into new areas - including AI, automation, and intelligent systems and we’re searching for someone who is excited to explore with us.\n\n📍 Location: Warsaw\n💰 Salary (PLN):\n24 000 – 27 000 net + VAT (B2B)\n\nWhat does AI-native mean for us? Not occasional ChatGPT prompts. AI tools are a core part of how you design, code, test and review – and you know when to trust the model and when to override it. You build it, you run it, you own it, including every line an agent wrote.\nWhat will you do and how can you grow with us?\nDesign and ship AI-powered products end to end in Golang and Node.js – RAG pipelines, AI agents, and the APIs and integrations around them – built to enterprise security and compliance standards.\n\nMake the right architecture calls: an agent or a single model call, RAG, fine-tuning or a better prompt – or plain code when that's the better tool.\n\nWork AI-first every day: coding agents, spec-first development, automated reviews and tests, and project-level AI context (e.g. CLAUDE.md or rules files) that the whole team benefits from.\n\nMake AI features production-ready: evals, monitoring of latency, cost and token usage, and catching hallucinations and security gaps before they reach users.\n\nJoin projects for clients of different backgrounds, both business- and consumer-targeted. Wondering what you'd work on? Check out a powerful cyber risk mitigation platform, a Norwegian eco-friendly start-up or something just as exciting!\n\nGain wide experience across many industries and ways of working, both for exciting startups and established enterprises like Siemens.\n\nOwn your work and decide on the project's direction.\n\nGrow fast through our internal knowledge-sharing initiatives – and share your own expertise with more junior team members, helping shape our standards for AI-assisted development.\n\nWhat we're looking for\nExperience:\n5+ years of professional software engineering experience, with strong expertise in Golang, Node.js or JavaScript (TypeScript welcome)\n\nHands-on experience shipping LLM-based features to production – not only demos\n\nTech skills:\nSolid understanding of LLM architectures, embeddings and vector search (RAG)\n\nDaily use of AI coding tools (e.g. Claude Code, Cursor, Copilot) and the ability to spot hallucinations, security risks and architectural drift in AI-generated code\n\nExperience integrating external APIs, databases and third-party tools into AI pipelines\n\nProficiency in building and consuming RESTful and GraphQL APIs\n\nExperience with cloud platforms (AWS, GCP or Azure), Docker and Kubernetes\n\nFamiliarity with MLOps practices: model deployment, monitoring and CI/CD for AI systems\n\nStrong background in data structures, algorithms and software design principles\n\nSoft skills:\nAt least B2 in English – we work internationally, so that's a must\n\nStrong collaboration, communication and organisation skills\n\nReadiness to work in an agile environment\n\nProactive attitude towards implementing changes\n\nAttention to detail\n\nNice to have:\nPractical experience developing AI agents, incl. MCP servers, tool calling or multi-agent setups\n\nLLM observability tools (e.g. Langfuse)\n\nPractical DDD experience\n\nKnowledge of Event Sourcing\n\nPassion for new technologies and startups\n\nPet projects, presence in the IT community\n\nAny other programming languages and frameworks\n\nWhat we offer:\nFlexible working hours,\n\nPossibility to work remotely with occasional visits to our office in Warsaw,\n\nGrowth-driven culture: knowledge-sharing initiatives, individual career paths, and regular evaluation of your development,\n\nFreedom to choose the best tools and tech to achieve your team’s goals,\n\nTrustworthy devices - we work on MacBooks.\n\nReady to join?\nIf you want to build AI products that actually make it to production, we'd love to hear from you. Let's build something great together!\nTech stack\nGolang\nAI coding","description_format":"text","description_chars":4286,"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":["Flexible schedule"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation","IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-14T14:25:15Z"}],"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":38,"reasons":["seen:0","win:early"],"computed_at":"2026-10-15T05:46:00Z"},"pay":{"stated_usd_annual":83028,"is_top_pay":false},"html_url":"https://alion.io/job/startup-house-senior-ai-native-developer","json_url":"https://alion.io/job/startup-house-senior-ai-native-developer.json","meta":{"generated_at":"2026-10-15T10:34:44Z","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":"crawler_verified","counted_by":"address","units_charged":1,"used_today":15985,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":1450},"rest":"https://alion.io/mcp/rest/get_company?id=1450"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fstartup-house-senior-ai-native-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%2Fstartup-house-senior-ai-native-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%2Fstartup-house-senior-ai-native-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/startup-house-senior-ai-native-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fstartup-house-senior-ai-native-developer"}]}
