Employment Type: FullTime

About the Role

Join an early-stage AI company building tools for the global logistics industry. In this high-ownership product engineering role, you will work closely with the founding team and customers to shape the product and bring AI-powered workflows into production.

What You'll Do

• Talk with customers and translate their needs into product direction and system architecture.

• Build full-stack features that combine user-friendly interfaces with LLM orchestration, agent workflows, and structured data pipelines.

• Improve the reliability, latency, and evaluation of AI features running in production.

• Turn early prototypes into robust systems, balancing delivery speed with maintainability and scale.

• Contribute to technical vision and product strategy, from architecture through delivery and iteration.

What We're Looking For

• At least 3 years of production experience building full-stack web applications with Node.js and TypeScript.

• Proficiency with React and experience designing MongoDB schemas with attention to flexibility and query performance.

• Production experience delivering LLM-powered features, including prompt engineering, structured output parsing, context management, and error recovery.

• Experience with distributed systems, serverless infrastructure, concurrency, and failure handling.

• Hands-on use of observability tools, including metrics and tracing, to debug production issues across asynchronous workflows.

• Experience with LLM orchestration, agent workflows, vector stores, embedding pipelines, and structured data.

• A track record of owning technical projects end to end, shipping customer-facing products, and iterating based on user feedback.

• Experience building complex B2B systems and working in an early-stage or founding environment. Logistics, supply chain, or operations experience is a plus.
