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.<\/p>\n<p>This is a full-stack role with no bias toward frontend or backend. You&#x27;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.<\/p>\n<p>Our projects span FinTech, Web3, marketplaces, SaaS platforms, and data-heavy admin systems. Experience in these domains is a plus, not a core requirement.<\/p>\n<p>You&#x27;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.<\/p>\n<p>What you&#x27;ll do<br \/>Set up projects correctly from day one: repository structure, design system and typography integration, environments, CI\/CD<br \/>Take designer-built interfaces to production: refine the code, connect data, make it stable and maintainable<br \/>Build MVP backends on Supabase: database schema, authentication, roles and permissions, row-level security, storage, edge functions<br \/>Own security: make sure users never see each other&#x27;s data, review access rules, catch unsafe patterns in AI-generated code<br \/>Integrate payments and third-party services; deploy and maintain production environments<br \/>Choose and justify the stack for each project and explain the choice to the client<br \/>Work with existing client codebases during redesign and modernization projects<br \/>Set up AI-driven testing: autotest logic, coverage of key flows, a QA process designers and external QA can follow<br \/>Review code, define engineering standards, and support designers working in code<br \/>Estimate projects accurately and take part in scoping and presales<br \/>Coordinate with partner backend teams on heavy, complex products<\/p>\n<p>What we&#x27;re looking for<br \/>4+ years of commercial development across both frontend and backend<br \/>Strong React and TypeScript (Next.js is a plus, not required)<br \/>Solid backend experience: Node.js or another server language, relational databases (PostgreSQL), API design<br \/>Hands-on Supabase or Firebase experience: auth, row-level security, access control<br \/>Experience deploying and running products in production (Vercel, cloud providers, CI\/CD)<br \/>Payment integrations or work with financial data<br \/>A portfolio of small to medium products you built end to end, with the ability to explain why each technology was chosen<br \/>Experience with more than one stack, so you can pick the right tool rather than default to one<br \/>Security mindset: authorization, data isolation, secrets management<br \/>Testing culture: unit and E2E (Jest, Playwright \/ Cypress), including tests written by AI<br \/>Experience working with existing codebases, refactoring, and migrations<\/p>\n<p>AI-native development is the core of the role<br \/>We build with AI every day, so we need real hands-on experience, not familiarity.<br \/>Daily work with Claude Code, Cursor, Codex, or similar agentic tools<br \/>Preparing context for agents: CLAUDE.md \/ cursor rules, MCP integrations, task decomposition<br \/>Critical review of AI-generated code: hallucinations, unsafe patterns, unnecessary abstractions<br \/>Understanding where AI saves time and where it creates technical debt<br \/>Ability to build an AI-driven workflow for the team, including designers who code<br \/>Ability to explain to a client how AI-native development affects timelines and cost<br \/>In the interview we&#x27;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.<\/p>\n<p>Communication<br \/>English B2+, confident in a one-hour client call without an interpreter<br \/>Comfortable talking to CTOs, founders, and C-level: structured, focused on business impact<br \/>Able to explain technical risks, trade-offs, and stack choices in business terms<br \/>Able to say &quot;no&quot; to a poor idea or unrealistic scope respectfully and on time<br \/>Clear written updates and documentation<\/p>\n<p>Growth to Team Lead<br \/>As you grow into the Lead role, you&#x27;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 &quot;no&quot; to a poor idea, and keep the relationship intact. If you&#x27;re a strong engineer but client communication feels like a burden, this role isn&#x27;t for you, and that&#x27;s fine.<\/p>\n<p>Your responsibilities will gradually include:<br \/>Direct client communication and calls with CTOs and founders<br \/>Presenting and defending architecture, stack choices, scope, and estimates<br \/>Translating business requirements into technical solutions and explaining risks in business language<br \/>Mentoring and onboarding developers and designers who work in code<br \/>Establishing engineering standards and code review guidelines<br \/>Technical coordination between our team, partner teams, and the client&#x27;s engineers<br \/>Technical interviews and candidate evaluation<br \/>Project estimation and presale support<\/p>\n<p>Nice to have<br \/>Product thinking: you care about what the MVP is for, not only how it&#x27;s built<br \/>Experience with Lovable, v0, Figma Make, or similar AI builders, and knowing their limits<br \/>Python, Go, or PHP backend experience<br \/>Analytics and A\/B testing setup for live products<br \/>Web3: WalletConnect, ethers.js \/ viem<br \/>Previous Tech Lead experience<br \/>Presale and project estimation experience<\/p>\n","protected":false},"excerpt":{"rendered":"<p>About the roleWe&#x27;re changing how products get built.
