  • We also enable features in this console that allow tens of thousands of users on IT security teams of our clients to manage our security SW deployed on endpoints in client's environments (e.g. investigating threats & notifications from protected devices; creating blocklists, exclusions, policies etc.).

You'll be joining a team with a significant impact on how our customers' environments (incl. 4 or Fortune10 companies, hundreds of Global2000 or governments) are protected, how they interact with agents, gain visibility into their security posture, and understand the risks and act upon them. As a core team, we're heavily involved in every end-to-end effort, features development and are key contributors to the design and build of the right architecture of client's cybersecurity solution to match the scale & hyper-growth of our business.


What will you do?

  • Design, develop and support backend system serving for endpoint security

  • Help us with initiatives around moving our services to a new deployment model.

  • Code Quality and Maintenance: Write clean, maintainable code. Stay up-to-date with the latest advancements in backend technologies and security best practices.

  • Innovation and Creativity: Bring creativity to the table. Explore new solutions and technologies to improve our product continuously.


Requirements: 

  • 7+ years of extensive software engineering experience, including proven expertise in developing large-scale distributed systems and microservices architecture, with a focus on performance, scalability and reliability

  • Proficiency in Java, Golang and Python 

  • Experience with cloud platforms (AWS and/or GCP) and Kubernetes (must)

  • Experience with Kafka or similar solutions is a plus

  • Excellent problem-solving skills

  • Strong communication skills and ability to articulate technical concepts and influence engineering direction across teams, departments and stakeholders


We offer:
