Full Job Description

đź“‹ Description

  • • As a Software Engineer on Zip's AI Foundations team, you will build the core platform that powers every AI-driven product across the company, enabling scalable, reliable, and reusable infrastructure for agentic systems, document processing, retrieval, and evaluation—directly impacting how Zip delivers intelligent procurement solutions to Fortune 500 clients like OpenAI, Snowflake, and JPMorgan Chase.
  • • You will design and implement end-to-end AI infrastructure including agentic orchestration (LangGraph), RAG pipelines, document parsing systems, memory architectures, and eval frameworks, working with significant autonomy to solve open-ended problems where established best practices are still emerging.
  • • You will collaborate closely with product teams across Intake AI, Chatbot, IP Agent, Contract Orchestration, and Payments to identify shared needs, abstract patterns, and ship platform-level capabilities that raise the quality and velocity of AI development organization-wide.
  • • You will own the reliability and observability of AI systems in production, building tracing, logging, metrics, and alerting tooling that ensures AI applications perform consistently and safely at scale.
  • • You will grow into a platform thinker who anticipates reuse, designs for broad adoption, and influences engineering standards across Zip—shaping how the company builds AI for years to come.
  • • You will work alongside elite engineers from Airbnb, Meta, Stripe, Salesforce, Apple, and Google in a high-impact, well-funded environment ($2.2B valuation, $370M raised) where your work directly contributes to redefining enterprise procurement in the age of AI.

🎯 Requirements

  • • Strong Python proficiency; experience with async frameworks and distributed systems is a plus
  • • Hands-on experience building or operating LLM-based applications — RAG pipelines, tool use, agents, or eval systems
  • • Experience with data pipelines, job scheduling (Airflow or equivalent), and vector databases or embedding-based search
  • • Comfort with observability tooling: tracing, logging, metrics, and alerting in production AI systems
  • • Ability to drive ambiguous, open-ended problems to a conclusion without a lot of hand-holding
