Senior/Staff Software Engineer (Platform)

ABOUT THE ROLE

You'll build the software backbone powering autonomous manufacturing operations at a seed-stage AI supply chain startup. As a Senior or Staff Software Engineer on the Platform team, you'll design scalable backend services, data pipelines, and integrations that coordinate AI-powered agents and high-stakes transactions across complex supply chain workflows, directly enabling physical goods to move reliably through manufacturing systems.

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.

- Strong TypeScript and Next.js hands-on experience, with recent, direct involvement in web development.

- Demonstrated experience designing systems with transactional guarantees (ACID semantics, exactly-once processing) and idempotent APIs.

- Experience building NLP/ML pipelines for data extraction 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 pipelines for state management and cross-system synchronization.

- Experience integrating with ERP systems (SAP, Oracle, or similar) and third-party APIs, including legacy or poorly documented interfaces.

- Direct, recent hands-on AI experience including agentic frameworks alongside web development work.

- Professional experience in manufacturing supply chain, procurement, or logistics domains.

- Comfort operating on a very small, fast-moving team with flexibility and a generalist mindset.

- Experience with Supabase or similar managed PostgreSQL platforms is a plus.

- Experience with RAG patterns or similar AI/ML infrastructure is a plus.

- Prior experience as a founder or founding engineer at a startup is strongly preferred.

- Strong computer science fundamentals.

COMPENSATION & BENEFITS

- Salary: $160,000 to $250,000 annually (USD), depending on level and experience.

- Visa sponsorship is available.

LOCATION

Fully remote (United States). Being based in or willing to work in San Francisco, California is preferred.
