Backend Developer
Join Bay and help secure the next wave of work, where AI agents write code and act on company data alongside the people who use them. Bay is the AI agent security platform that gives enterprises visibility into every agent across devices, browsers and cloud workloads, and control over what those agents do in real time. That way, security teams can back AI adoption instead of slowing it down.
The role
We’re looking for a Backend Developer to design and build the services at the core of Bay Cloud. That covers everything from ingesting agent activity at scale to the risk scoring and policy compilation behind every Allow, Ask, Deny or Steer decision. You’ll join a small, senior R&D team in Tel Aviv that ships to production daily and treats AI tools as a core part of how it works.
What you’ll do
- Design, build and own the backend services behind Bay Cloud: APIs, data models and the business logic that powers the platform.
- Build the pipelines that ingest millions of events from devices, browsers and cloud workloads, normalize them and turn them into an entity graph, activity timelines and findings.
- Develop the services that score risk continuously and compile policies per device and agent, so enforcement decisions happen in milliseconds.
- Own reliability and scale, from performance and observability to testing, code reviews and production support.
- Work directly with product, frontend and customers to shape what we build next, and help set our architecture as we grow.
What we’re looking for
- 5+ years of hands-on backend development, building and owning services in production.
- Heavy, hands-on use of AI coding tools, with automation built into how you work.
- Strong TypeScript and Node.js, or another modern backend language such as Go or Python.
- Deep experience with PostgreSQL, data modeling and API design (REST or GraphQL).
- Experience building distributed, cloud-native systems on AWS, with containers and Kubernetes.
- A builder’s mindset: you take a vague problem, break it down and deliver at startup pace.
- Strong communication in English and Hebrew.
Nice to have
- Background in cybersecurity products (endpoint, API, cloud or identity security).
- Experience with event streaming and queues (Kafka, SQS or similar), high-scale data processing or graph databases.
- Experience from an elite technology unit (8200, Mamram or similar), or a B.Sc. in Computer Science or equivalent experience.
Why join Bay
- Build a new category of AI agent security from the ground floor, with enterprise customers including Micron Technology, Peloton and ClickUp already live.
- High ownership: your code reaches customers within days, not quarters.
- Work with a senior team of engineers who have built and scaled security products before.
- Competitive salary and meaningful equity in a well-funded, Series A stage company.
