Department: Engineering

Location: San Francisco

Employment Type: FullTime

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.
