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.
