Senior/Staff Software Engineer (Platform)

Job Description

### About the Role

Join the Platform team at an early-stage AI-powered manufacturing supply chain company. You will build the backend services, data pipelines, and integrations that coordinate intelligent agents and support reliable movement of goods through complex manufacturing workflows.

### What You'll Do

* Design and scale backend services, 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 synchronization across systems.

* Implement caching, rate limiting, and reliability patterns for external API calls.

* Establish monitoring, alerting, and observability practices, and take ownership of backend incident response.

### What We're Looking For

* At least 5 years of production experience building backend services, data pipelines, or platform infrastructure, with Senior or Staff-level scope.

* Recent hands-on experience with TypeScript, Next.js, and AI or agentic frameworks in web development.

* Experience building NLP/ML pipelines to extract information from unstructured documents, including OCR.

* Strong understanding of transactional guarantees, including ACID semantics, exactly-once processing, and idempotent APIs.

* Experience with PostgreSQL or relational databases, event-driven systems, message queues, and reliable data pipelines.

* Experience integrating ERP systems and third-party APIs, including legacy or poorly documented interfaces.

* Background in manufacturing supply chain, procurement, or logistics, plus experience with observability and incident response.

* Familiarity with LLM agents, RAG, or managed PostgreSQL platforms is useful.
