Product Engineer

ABOUT THE ROLE You'll work directly with the founding team to build AI agents that automate real operations in global sea and air freight. This is a high-ownership, full-stack role where you'll make foundational technical decisions and put product directly into the hands of users in one of the world's most critical industries. WHAT YOU'LL DO - Talk directly to customers and translate their needs into product direction and system architecture. - Build full-stack features combining intuitive interfaces with intelligent backend logic, including LLM orchestration, agent workflows, and structured data pipelines. - Push the limits of what LLMs and agents can do in production, tackling hard problems around reliability, latency, and evaluation. - Scale from demo-quality code to robust, production-ready systems, making deliberate tradeoffs between speed and durability. - Help shape the technical vision and product strategy of the company. WHAT WE'RE LOOKING FOR - 3 or more years building full-stack web applications with Node.js and TypeScript in production environments. - Hands-on production experience with LLM-powered features, including prompt engineering, structured output parsing, context window management, and error recovery. - Proficiency in React for building user-facing interfaces. - Experience designing MongoDB schemas with attention to query performance and flexibility. - Experience building distributed systems and serverless infrastructure, including handling concurrency, failure modes, and scale. - Familiarity with observability tooling (such as Datadog) for debugging production issues across async workflows using metrics and tracing. - Experience with LLM orchestration, agent workflows, and structured data pipelines. - Demonstrated track record of taking full ownership of projects from architecture through delivery and iteration. - Familiarity with vector stores and embedding pipelines for AI applications is a plus. - Domain knowledge of logistics, supply chain, or operations is a plus, but not required. - High-agency mindset, comfort with ambiguity, and genuine curiosity about how industries work.
