Senior/Staff Software Engineer (Platform)

About the Role Join a well-funded, Series A startup building an AI-powered operations platform for US manufacturers. As a Senior/Staff Software Engineer (Platform) , you'll be at the heart of the engineering team — designing the software layer that enables autonomous manufacturing operations. You'll build scalable backend services, intelligent data pipelines, and deep integrations with ERP and freight systems that keep physical goods moving reliably. This role is central to coordinating AI-powered agents and high-stakes transaction processing across complex supply chain and manufacturing workflows. Visa sponsorship is available. 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 to ensure reliability and performance of external API calls at scale. Drive platform reliability: Establish monitoring, alerting, and observability patterns; own incident response for backend systems. What We're Looking For Required: Hands-on experience within the supply chain domain (procurement, logistics, manufacturing workflows, or similar). Proven ability to design and implement 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. Experience 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 / Supabase LLMs, embeddings, vector databases, RAG architectures AWS, containerization, CI/CD RESTful patterns, serverless functions Nice to Have: 2–10+ years of software engineering experience, with meaningful backend and platform ownership. Familiarity with manufacturing sectors such as food & beverage, supplements, cosmetics, chemicals, or consumer goods. Compensation & Benefits Salary: $160,000 – $250,000 USD per year, depending on experience and level. Visa sponsorship available. Location This is an on-site role based in San Francisco, CA .
