About the Role Join a seed-funded AI and supply chain automation startup serving US manufacturers. As a Senior/Staff Platform Engineer, you will build the software layer that powers autonomous manufacturing operations — designing scalable backend services, intelligent data pipelines, and deep integrations with ERP and freight systems that move physical goods reliably. This is a high-impact, foundational role at a small, fast-moving team. What You'll Do Design and scale backend services: Architect Next.js API routes, background jobs, and serverless functions to handle high-throughput order processing. Build AI-powered agents: Develop and productionize LLM-based agents, AI/ML infrastructure, and RAG patterns for intelligent quote analysis and supplier recommendations. Own the data layer: Design Supabase/PostgreSQL schemas, migrations, and complex queries covering materials, quotes, orders, and supplier relationships. Architect event-driven systems: Build reliable pipelines for order state management, notification triggers, and cross-system synchronization. Implement caching and rate limiting: Design strategies for external API calls to ensure reliability at scale. Drive platform reliability: Establish monitoring, alerting, and observability patterns; own incident response for all backend systems. What We're Looking For Required: Experience within the supply chain domain (manufacturing, procurement, logistics, or freight workflows). Proven experience designing reliable data processing with transactional guarantees — ACID semantics, exactly-once processing, and idempotent APIs. Experience with NLP/ML pipelines for extracting data from unstructured documents and emails, including OCR and information extraction. Familiarity integrating with ERP systems (e.g., SAP, Oracle) and freight/carrier APIs, including legacy or poorly documented interfaces. Strong computer science fundamentals; all educational backgrounds welcome. Tech stack: TypeScript, Node.js, Python, PostgreSQL, LLMs, embeddings, vector databases, RAG architectures, AWS, containerization, CI/CD, RESTful patterns. 2–10+ years of relevant software engineering experience. Compensation & Benefits Salary: $160,000 – $250,000 USD annually Visa sponsorship available Location On-site in San Francisco, CA, United States . This role is not remote.
