Based in our Tel Aviv office, you will collaborate with elite engineers to productionize models and ensure reliability, performance, and security.

Qualifications

• 6 years of backend engineering experience with Python.
• Experience with scalable backend infra (FastAPI, Kafka/Redis, Docker/Kubernetes).
• Secure software design practices (API security, data protection).
• Ability to own features end-to-end from architecture to deployment.
• Familiarity with LLM/AI concepts in production.

Responsibilities

• Architect and build backend infrastructure powering secure, scalable AI workflows.
• Develop core systems for multi-agent reasoning, retrieval pipelines, and tool execution.
• Productionize AI models and agent workflows with strong reliability and performance guarantees.
• Integrate AI services across the product stack, from backend APIs to user-facing workflows.
• Own systems end-to-end: design, implementation, deployment, monitoring, and iteration.
• Apply secure engineering principles across APIs, data flows, and deployment.

Job description

DLP's rule-based framework is broken. We asked machines to find problems with rigid rules, then expected humans to investigate the noise - an impossible task. Jazz is the new model. It starts with total coverage from a forensic endpoint agent and uses a powerful Agentic Investigator that learns your business. It delivers clear, pre-investigated answers instead of alerts, and is designed to be run by a single person. Finally, DLP that works.

Founded in 2024 and backed by leading cybersecurity VCs, we are already deployed with customers worldwide and growing quickly. We're a team obsessed with solving hard problems the right way, and we're looking for builders to join us.

We're now looking for a world-class Senior Software Engineer to help architect and build the core systems behind our AI security engine.

As part of our AI Cybersecurity team, you'll design and build the infrastructure and agent workflows that power Jazz's security platform. This is a full-lifecycle engineering role, covering backend systems, AI agent development, and product integration, with a focus on building workflows that are reliable, scalable, and production-ready.

What You'll Do

• Architect and build backend infrastructure powering secure, scalable AI workflows.
• Develop core systems for multi-agent reasoning, retrieval pipelines, and tool execution.
• Productionize AI models and agent workflows with strong reliability and performance guarantees.
• Integrate AI services across the product stack, from backend APIs to user-facing workflows.
• Own systems end-to-end: design, implementation, deployment, monitoring, and iteration.
• Apply secure engineering principles across everything you build, from APIs and data flows to infrastructure and deployment.

What We're Looking For

• 6 years of experience in backend engineering, with strong proficiency in Python and distributed systems.
• Experience building and operating scalable, reliable backend infrastructure (FastAPI, Kafka/Redis, Docker/Kubernetes, observability).
• Solid understanding of secure software design, including safe API development, data protection, and security-oriented engineering practices.
• Ability to own features end-to-end - from architecture and implementation to deployment, monitoring, and ongoing improvements.
• Familiarity with LLM/AI concepts (agents, retrieval, vector search) and the ability to work with these components in production systems.

Why Join Jazz?

• Work on cutting-edge AI cybersecurity challenges.
• Architect systems with massive technical depth and scale.
• High ownership and autonomy in an early-stage environment.
• Direct impact on product outcomes and engineering decisions.
• Collaborate with elite engineers and founders who have built large-scale systems before.

Our office is at Sonol Tower in Tel Aviv, next to Carlebach train station.
