Senior/Staff Software Engineer (Platform)

About the Role

Join a seed-funded AI and supply chain automation startup serving US manufacturers. As a Senior/Staff Platform Engineer, you will build the software layer that powers autonomous manufacturing operations - designing scalable backend services, intelligent data pipelines, and deep integrations with ERP and freight systems that move physical goods reliably. This is a high-impact, foundational role at a small, fast-moving team.
What You'll Do

• Design and scale backend services: Architect Next.js API routes, background jobs, and serverless functions to handle high-throughput order processing.
• Build AI-powered agents: Develop and productionize LLM-based agents, AI/ML infrastructure, and RAG patterns for intelligent quote analysis and supplier recommendations.
• Own the data layer: Design Supabase/PostgreSQL schemas, migrations, and complex queries covering materials, quotes, orders, and supplier relationships.
• Architect event-driven systems: Build reliable pipelines for order state management, notification triggers, and cross-system synchronization.
• Implement caching and rate limiting: Design strategies for external API calls to ensure reliability at scale.
• Drive platform reliability: Establish monitoring, alerting, and observability patterns; own incident response for all backend systems.

What We're Looking For

• Required: Experience within the supply chain domain (manufacturing, procurement, logistics, or freight workflows).
• Proven experience designing reliable data processing with transactional guarantees - ACID semantics, exactly-once processing, and idempotent APIs.
• Experience with NLP/ML pipelines for extracting data from unstructured documents and emails, including OCR and information extraction.
• Familiarity integrating with ERP systems (e.g., SAP, Oracle) and freight/carrier APIs, including legacy or poorly documented interfaces.
• Strong computer science fundamentals; all educational backgrounds welcome.
• Tech stack: TypeScript, Node.js, Python, PostgreSQL, LLMs, embeddings, vector databases, RAG architectures, AWS, containerization, CI/CD, RESTful patterns.
• 2-10+ years of relevant software engineering experience.

Compensation & Benefits

• Salary: $160,000 - $250,000 USD annually
• Visa sponsorship available
