Our designers now create interfaces directly in code with Claude Design and Claude Code, so design and frontend arrive together. We need a senior engineer who takes it from there: sets the project up properly, builds the backend, secures it, and ships it to production.\n\nThis is a full-stack role with no bias toward frontend or backend. You'll work on fixed-price MVPs delivered turnkey and deploy-ready, on growth retainers after launch, and on modernizing existing client products to the new AI-native approach.\n\nOur projects span FinTech, Web3, marketplaces, SaaS platforms, and data-heavy admin systems. Experience in these domains is a plus, not a core requirement.\n\nYou'll be the technical owner across our projects: choosing the stack, setting standards, reviewing code, and helping designers solve technical problems. The role has a clear growth path toward Team Lead.\n\nWhat you'll do\n\nSet up projects correctly from day one: repository structure, design system and typography integration, environments, CI/CD\n\nTake designer-built interfaces to production: refine the code, connect data, make it stable and maintainable\n\nBuild MVP backends on Supabase: database schema, authentication, roles and permissions, row-level security, storage, edge functions\n\nOwn security: make sure users never see each other's data, review access rules, catch unsafe patterns in AI-generated code\n\nIntegrate payments and third-party services; deploy and maintain production environments\n\nChoose and justify the stack for each project and explain the choice to the client\n\nWork with existing client codebases during redesign and modernization projects\n\nSet up AI-driven testing: autotest logic, coverage of key flows, a QA process designers and external QA can follow\n\nReview code, define engineering standards, and support designers working in code\n\nEstimate projects accurately and take part in scoping and presales\n\nCoordinate with partner backend teams on heavy, complex products\n\nWhat we're looking for\n\n4+ years of commercial development across both frontend and backend\n\nStrong React and TypeScript (Next.js is a plus, not required)\n\nSolid backend experience: Node.js or another server language, relational databases (PostgreSQL), API design\n\nHands-on Supabase or Firebase experience: auth, row-level security, access control\n\nExperience deploying and running products in production (Vercel, cloud providers, CI/CD)\n\nPayment integrations or work with financial data\n\nA portfolio of small to medium products you built end to end, with the ability to explain why each technology was chosen\n\nExperience with more than one stack, so you can pick the right tool rather than default to one\n\nSecurity mindset: authorization, data isolation, secrets management\n\nTesting culture: unit and E2E (Jest, Playwright / Cypress), including tests written by AI\n\nExperience working with existing codebases, refactoring, and migrations\n\nAI-native development is the core of the role\n\nWe build with AI every day, so we need real hands-on experience, not familiarity.\n\nDaily work with Claude Code, Cursor, Codex, or similar agentic tools\n\nPreparing context for agents: CLAUDE.md / cursor rules, MCP integrations, task decomposition\n\nCritical review of AI-generated code: hallucinations, unsafe patterns, unnecessary abstractions\n\nUnderstanding where AI saves time and where it creates technical debt\n\nAbility to build an AI-driven workflow for the team, including designers who code\n\nAbility to explain to a client how AI-native development affects timelines and cost\n\nIn the interview we'll ask you to walk us through a real case: a product you built with an agent, how you set up the process, and what went wrong.\n\nCommunication\n\nEnglish B2+, confident in a one-hour client call without an interpreter\n\nComfortable talking to CTOs, founders, and C-level: structured, focused on business impact\n\nAble to explain technical risks, trade-offs, and stack choices in business terms\n\nAble to say \"no\" to a poor idea or unrealistic scope respectfully and on time\n\nClear written updates and documentation\nGrowth to Team Lead\n\nAs you grow into the Lead role, you'll join client calls with CTOs, founders, and C-level stakeholders. We need someone who can explain a technical decision through its business impact, give a reasoned \"no\" to a poor idea, and keep the relationship intact. If you're a strong engineer but client communication feels like a burden, this role isn't for you, and that's fine.\n\nYour responsibilities will gradually include:\n\nDirect client communication and calls with CTOs and founders\n\nPresenting and defending architecture, stack choices, scope, and estimates\n\nTranslating business requirements into technical solutions and explaining risks in business language\n\nMentoring and onboarding developers and designers who work in code\n\nEstablishing engineering standards and code review guidelines\n\nTechnical coordination between our team, partner teams, and the client's engineers\n\nTechnical interviews and candidate evaluation\n\nProject estimation and presale support\nNice to have\n\nProduct thinking: you care about what the MVP is for, not only how it's built\n\nExperience with Lovable, v0, Figma Make, or similar AI builders, and knowing their limits\n\nPython, Go, or PHP backend experience\n\nAnalytics and A/B testing setup for live products\n\nWeb3: WalletConnect, ethers.js / viem\n\nPrevious Tech Lead experience\n\nPresale and project estimation experience","description_format":"text","description_chars":5495,"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":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Cybersecurity","Design & Creative"],"lifecycle":[{"event":"open","at":"2026-10-29T15:24:45Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":0.85,"p_active":0.422,"p_room":0.35,"age_days":25,"expected_fill_days":7,"reasons":["seen:25","win:tail"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/arounda-senior-full-stack-engineer-ai-native","json_url":"https://alion.io/job/arounda-senior-full-stack-engineer-ai-native.json","meta":{"generated_at":"2026-10-31T13:55:01Z","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":21576,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":101915},"rest":"https://alion.io/mcp/rest/get_company?id=101915"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Farounda-senior-full-stack-engineer-ai-native"},{"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%2Farounda-senior-full-stack-engineer-ai-native"},{"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%2Farounda-senior-full-stack-engineer-ai-native"},{"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/arounda-senior-full-stack-engineer-ai-native\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Farounda-senior-full-stack-engineer-ai-native"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3466796}},{"tool":"search_jobs","arguments":{"company":"arounda.agency","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3466796},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
