Senior Data Engineer (AI & Data Products)

We are looking for a Senior Data Engineer with 6–10 years of experience to own the Python data pipelines and data ontology behind systemzero's AI-native operating system for CFOs. You'll be a hands-on IC who owns problems end to end, solves them without waiting to be told how, and wants to grow into a tech lead. Over the next 6 months you'll guide a core data team of four, made up of a mid-level engineer and two new hires. You'll report directly to the CTO in a flat, low-ego team that works through problems together. Your work decides whether our agents can reason correctly over GAAP-grade financial data, where hallucinations aren't tolerated.

What will you be doing?

• Building and owning production Python pipelines that load customer data into our graph and vector store (SurrealDB)
• Adding new data providers and connectors to the platform, such as Snowflake, ERP, accounting and billing systems
• Designing the data ontology so that AI retrieval and agent reasoning across multi-entity financial data stays accurate
• Owning your work end to end across data, DevOps and infrastructure in a remote-first team that solves problems together on frequent calls
• Moving from about 80% IC work toward a 60/40 split, with the 40% spent mentoring the core data team and shaping long-term data architecture
