We're not a staff-augmentation shop: every person we put in front of a client represents Katapult, co-creates product, and owns the outcome directly, with no managers or leads acting as a layer in between.\nThe Role\nWe're looking for a Full-Stack Builder to join the founding technical team behind one of our partners, an early-stage product with big ambitions to become a real tech company: web platform, mobile app, and everything in between. Our partner already has a first version of their site live, built by a non-technical founding team full of product ideas. We need someone who can step in, understand and harden the existing architecture, refactor where needed, and help seed the technical process for building product going forward.\nThis is a builder role, not a heavy-architecture or platform-engineering seat. You'll move fast, ship with sufficient quality, and work closely with a product-minded team that cares deeply about user experience and engagement. Mobile development isn't required from day one, but the team expects to build a mobile app down the line, so comfort picking that up matters. If the engagement goes well, this grows into a two-builder team supporting the full platform.\nKey Responsibilities\nUnderstand and evaluate the current architecture of our partner's existing web platform\n\nRefactor and harden the codebase to support rapid, reliable iteration\n\nBuild new features end-to-end, working closely with the product lead on UX and engagement-focused functionality\n\nHelp establish lightweight technical processes (code review, deployment, documentation) as the team scales\n\nCollaborate directly with a technical product manager and design lead in a fast-moving, startup environment\n\nBe ready to extend work into mobile development as the product roadmap evolves\n\nRequirements\nAdvanced conversational English, since all collaboration happens in English\n\nStrong full-stack engineering experience with modern web technologies (frontend and backend)\n\nDemonstrated ability to work as a builder: shipping fast, with just enough architecture, not over-engineering\n\nComfort working directly with founders and non-technical stakeholders, translating product vision into working software\n\nExperience refactoring or hardening an existing early-stage codebase\n\nProduct analytics tooling (Amplitude, PostHog, or similar)\n\nAgentic mindset: comfortable using AI coding tools (Cursor, Claude Code, etc.) as part of daily workflow\n\nStrong communication skills, comfortable asking clarifying questions and flagging blockers early\n\nNice to Have\nPrior experience building consumer-facing (B2C) products with high user engagement\n\nMobile development experience (native or cross-platform)\n\nExperience working in a 0-to-1 startup environment alongside a small, fast-moving team\n\nWork-Life Balance\nWork from Anywhere in Latin America: Enjoy the freedom to work remotely from any country in Latin America.\n\n23 Days of PTO per Year: Take time to recharge with paid time off, accrued monthly (1.91 days/month).\n\nUSA Federal Holidays\n\nFinancial Benefits\nMonthly Payment in USD: Get paid in US dollars, no matter where you are.\n\nContractor Agreement with No End Date: Enjoy the stability of a long-term contract.","description_format":"text","description_chars":3350,"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":[{"language":"English","level":"All
