Senior AI Engineer

Location: Tel-Aviv (IL)

Description

ONE ZERO is Israel’s fully digital, branchless private bank—created to bring private-banking level service to a broader public through advanced technology, automation, and AI led by Prof. Amnon Shashua. Building on this mission, we’re developing Ella—our GenAI “banking copilot”—to make money management simpler and more proactive, turning complex financial moments into clear, personalized insights while maintaining the trust, safety, and rigor expected from a regulated bank.

Ella (Tech): A GenAI agent embedded in ONE ZERO’s product flows and banking systems—not a chatbot bolted on—providing 24/7, multilingual help and daily “financial check-ups” that scan accounts and cards to flag anomalies, double charges, and savings opportunities.

Under the hood, we run an agentic, graph-based workflow (stateful orchestration) on top of leading LLMs: intents route through retrieval and verification steps, then into a typed actions/tool layer that can query live banking data and drive in-app workflows.

Why join: A rare chance to ship real, high-impact AI in a high scale production environment—with serious AI/engineering challenges in safety, and reliability, and daily “real-world” edge cases to solve.
