Senior/Staff Software Engineer (Platform)

ABOUT THE ROLE You'll build the software backbone powering autonomous manufacturing operations for an early-stage AI supply chain startup. As a Senior or Staff Software Engineer on the Platform team, you'll design scalable backend services, data pipelines, and integrations that coordinate AI-powered agents and high-stakes transactions across complex supply chain workflows, directly enabling physical goods to move reliably through manufacturing systems. WHAT YOU'LL DO - Design and scale backend services using Next.js API routes, background jobs, and serverless functions to handle high-throughput order processing. - Build and productionize LLM-based agents, AI/ML infrastructure, and RAG patterns for intelligent quote analysis and supplier recommendations. - Own the data layer by designing PostgreSQL schemas, migrations, and complex queries for materials, quotes, orders, and supplier relationships. - Architect event-driven systems with reliable pipelines for order state management, notification triggers, and cross-system synchronization. - Implement caching and rate limiting strategies to ensure reliable external API calls at scale. - Establish monitoring, alerting, and observability patterns, and own incident response for backend systems. WHAT WE'RE LOOKING FOR - 5+ years building backend services, data pipelines, or platform infrastructure in production environments. - Strong CS fundamentals and experience designing systems with transactional guarantees (ACID semantics, exactly-once processing) and idempotent APIs. - Experience building NLP/ML pipelines for data extraction from unstructured documents, including OCR and information extraction. - Experience designing and scaling PostgreSQL or relational database schemas, migrations, and complex queries for transactional workloads. - Experience building event-driven systems, message queues, or reliable data pipelines for state management and cross-system synchronization. - Experience integrating with ERP systems (SAP, Oracle, or similar) and third-party APIs, including legacy or poorly documented interfaces. - Professional experience in manufacturing supply chain, procurement, or logistics domains. - Familiarity with Next.js API routes or serverless architectures for high-throughput workloads is a plus. - Experience with managed PostgreSQL platforms, RAG patterns, or productionizing LLM-based agents in backend systems is a plus. COMPENSATION & BENEFITS Salary range: $160,000 to $250,000 USD annually. Equity included. Visa sponsorship is available. LOCATION This is a fully remote role open to candidates based in the United States, with San Francisco, California as the primary anchor location.
