Senior/Staff Software Engineer, Platform

ABOUT THE ROLE

Join the platform team at an early-stage AI and manufacturing supply chain company. You will build the backend services, data pipelines, and integrations that coordinate AI-powered agents and transactions across manufacturing workflows, helping ensure physical goods move reliably through complex operations.

WHAT YOU'LL DO

• Design and scale backend services using Next.js API routes, background jobs, and serverless functions for high-throughput order processing.
• Build and productionize LLM-based agents, AI/ML infrastructure, and RAG patterns for quote analysis and supplier recommendations.
• Design PostgreSQL schemas, migrations, and complex queries for materials, quotes, orders, and supplier relationships.
• Build event-driven pipelines for order state management, notifications, and cross-system synchronization.
• Implement caching, rate limiting, and reliability strategies for external API calls.
• Establish monitoring, alerting, and observability practices, and own backend incident response.

WHAT WE'RE LOOKING FOR

• At least 5 years of production experience building backend services, data pipelines, or platform infrastructure.
• Professional TypeScript experience, with recent hands-on work using Next.js and direct web development experience.
• Experience designing transactional systems with ACID guarantees, exactly-once processing, and idempotent APIs.
• Hands-on AI development or AI DevOps experience, including NLP or ML pipelines for extracting information from unstructured documents, such as OCR workflows.
• Experience building or productionizing LLM-based agents, working with agentic frameworks, or implementing RAG patterns.
• Strong PostgreSQL and relational database skills, plus experience with event-driven systems, queues, or reliable data pipelines.
• Experience integrating ERP systems and third-party APIs, including legacy or poorly documented interfaces.
• Experience with monitoring, alerting, observability, and incident response for backend systems.
• Professional experience in manufacturing supply chain, procurement, or logistics, ideally in a startup or small company.
