Senior/Staff Software Engineer, Platform

About the Role

Join the platform team at an early-stage AI company building software for manufacturing operations and supply chains. You will develop the backend services, data systems, and AI capabilities that help coordinate procurement and order workflows reliably.

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 workflows 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 and rate limiting strategies for reliable external API integrations.
• Establish monitoring, alerting, and observability practices, and own backend incident response.

What We're Looking For

• Staff or Senior Staff-level experience, with a track record of building products and systems from the ground up; 4 to 12 years of professional experience.
• Professional TypeScript experience and recent hands-on work with Next.js, plus full-stack experience across TypeScript, Python, and Go.
• Strong data engineering skills, including building pipelines and large-scale data processing systems.
• Hands-on AI development or AI infrastructure experience in a startup or small-company environment, including production LLM products, AI tooling, LLMOps, model evaluation, and familiarity with the AI/ML lifecycle.
• Experience with AWS or other cloud infrastructure, security, and data privacy.
• Experience building internal tools and owning systems end to end; familiarity with manufacturing supply chain, procurement, or logistics is valuable.
• Experience with agent orchestration frameworks, RAG patterns, or PostgreSQL schema design is also relevant.
