Senior Full Stack Engineer

About the project: US-based startup building an enterprise AI operating system for real assets, similar in spirit to Palantir Foundry/AIP. The platform connects to a company's existing systems, models its business as an ontology, and runs AI agents that automate multi-step workflows. The company started in real estate and is now expanding into e-commerce and warehouse operations. Requirements: Strong TypeScript and solid backend experience, NestJS preferred. Hands-on experience with TypeScript, React and Next.js; you are comfortable owning both frontend and backend. Proven experience building integrations with enterprise systems (ERP, WMS, OMS or similar). Experience with event-driven architecture (Kafka). Background in e-commerce, grocery delivery, logistics or warehouse operations. Experience with AI-assisted development tools. Entrepreneurial mindset: end-to-end ownership, independence, and an understanding of the business problem behind each task. Good English (spoken and written). Nice to have: Experience integrating with SAP ERP and/or WMS, especially Manhattan Associates. Experience with PostgreSQL, AWS, LangChain or LLM-based applications. Responsibilities: Design, build and maintain backend services and integrations with enterprise systems (SAP, Manhattan WMS, Oracle SQL, Samsara). Extend the platform's ontology and integration layer to support new clients and domains. Build event-driven data flows and workflows on Kafka. Develop frontend features in React/Next.js and take features from UI to database. Contribute to agentic AI applications, including voice and chat agents for customer care. Work closely with the CEO, CTO, and the US team to turn business problems into working solutions. Own your work end to end, from understanding the problem to delivery. Benefits: Full-time, long-term engagement as an individual contributor (technical leadership stays with the CTO and co-founder). 15 days of paid vacation. Direct work with the founders and real influence on product and architecture. A chance to work on enterprise AI with real clients and real operations. Remote work.
