The company provides E-2/O-1 visa sponsorship and covers relocation costs.\nResponsibilities\nDesign, implement, test, deploy, and operate full-stack product features.\nBuild frontend experiences with TypeScript, JavaScript, React, Next.js, or Svelte.\nDevelop backend services and APIs with Node.js or Python.\nDesign PostgreSQL schemas, write production SQL, and improve query performance.\nBuild integrations and data-ingestion workflows for fragmented operational systems, documents, APIs, and business data.\nTranslate customer and operational requirements into maintainable technical solutions.\nOwn delivered features through production, including monitoring, debugging, incident resolution, and iteration.\nCommunicate technical proposals, delivery estimates, risks, and trade-offs clearly to founders, deployment strategists, and engineers.\nMaintain high standards for code quality, testing, security, reliability, and long-term maintainability.\nUse AI coding tools to improve development speed while validating generated code through review, tests, and production safeguards.\nContribute to a fast-moving product environment where engineers work with incomplete requirements and take responsibility for outcomes.\nRelocate from Warsaw to the United States within approximately six months of starting.\nRequired experience\nProfessional experience building production software as a full-stack engineer.\nHands-on TypeScript or JavaScript experience.\nHands-on React, Next.js, or Svelte experience.\nHands-on backend development with Node.js or Python.\nProduction experience with PostgreSQL and SQL.\nEvidence of owning features or systems from initial implementation through production operation.\nExperience designing or implementing APIs, integrations, or data-ingestion workflows.\nAbility to communicate technical decisions, delivery commitments, risks, and trade-offs clearly.\nEvidence of independently building software outside narrowly defined ticket work, such as a shipped side project, open-source contribution, hackathon project, or zero-to-one product.\nConfirmed willingness to relocate to the United States within approximately six months.\nTechnical environment\nTypeScript and JavaScript.\nReact, Next.js, and Svelte.\nNode.js and Python.\nPostgreSQL and SQL.\nFull-stack SaaS applications.\nAPIs, integrations, and data-ingestion pipelines.\nAI coding tools.\nProduction systems supporting complex procurement and distribution workflows.\nSuccess measures\nCustomer-useful features are shipped reliably from concept through production.\nImplementations remain maintainable, tested, observable, and aligned with the product’s operational requirements.\nFrontend, backend, database, and integration work is delivered as a coherent end-to-end system.\nProduction issues are diagnosed and resolved with appropriate urgency and technical rigor.\nTechnical decisions reduce manual operational work and improve the speed, accuracy, or reliability of customer workflows.\nAI coding tools increase engineering effectiveness without lowering standards for correctness, security, or maintainability.\nThe engineer completes the planned relocation to the United States within the expected timeframe.","description_format":"text","description_chars":3651,"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":[],"hiring_excludes":[],"relocation_offered":true,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-19T17:53:06Z"}],"visa":[],"liveness":{"score":54,"band":"ok","label":"Likely
