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 engineering challenges in safety, and reliability, and daily “real-world” edge cases to solve.
- AI-native development mindset: ability to use AI across the full software lifecycle (planning/design, implementation, testing, refactoring, maintenance) while keeping high standards for architecture, quality, security, scalability, and reliability.
- 3+ years building production software as a an engineer.
- 2+ years of hands-on experience integrating GenAI/LLM capabilities into production applications, including strong prompt engineering.
- Strong Python + TypeScript (React/Next.js experience preferred).
- Experience with cloud platforms (AWS/GCP/Azure) and containerization (Docker, Kubernetes).
- Skill set includes software engineering, data infrastructure, and familiarity with RDBMS/NoSQL.
- Experience with LangChain/LangGraph or other agent frameworks.
- Strong problem-solving skills with the ability to translate business requirements into scalable technical solutions.
