Senior/Staff Software Engineer (Platform)

About the Role

This is a platform engineering role at an early-stage AI startup building autonomous back-office and supply chain operations for US manufacturers. You will design and own the backend systems, data pipelines, and AI integrations that coordinate intelligent agents and high-stakes transactions across complex manufacturing workflows. The work is foundational and high-impact on a very small team.

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 while owning incident response for backend systems.

What We're Looking For

• 5 or more years building backend services, data pipelines, or platform infrastructure in production environments.
• Deep, recent hands-on experience with TypeScript and Next.js.
• Direct experience with AI or agentic frameworks alongside web-development expertise, including LLM-based agents, RAG patterns, or productionizing ML models in backend systems.
• Demonstrated ability to design and implement systems with transactional guarantees (ACID semantics, exactly-once processing) and idempotent APIs.
• Experience building NLP/ML pipelines for extracting data from unstructured documents, including OCR and information extraction.
• Experience designing and scaling PostgreSQL or relational database schemas 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 or legacy APIs.
• Professional background in manufacturing supply chain, procurement, or logistics domains.
• Comfort operating on a very small startup team without rigid processes; prior founding or founding-engineer experience is a strong plus.
• Strong computer science fundamentals.

Compensation & Benefits

• Salary range: $160,000 to $250,000 per year (USD).
• Visa sponsorship is available.

Location

Fully remote (US). San Francisco, California is preferred for candidates open to working on-site or hybrid, but remote candidates across the United States are welcome.
