Senior/Staff macOS Software Engineer

What are we looking for?

We are continuously expanding SentinelOne's capabilities, actively listening to customers and responding to their needs. We are looking for a Senior or Staff-level macOS Software Engineer who will be directly involved in our core technology and ensure we are always staying ahead of cybercriminals and deliver best-in-class detection.

As we're expanding our presence in EMEA, we're looking for multiple colleagues for macOS team - so it's a unique chance for you to join together as a team with other folks you enjoy working with!

What will you do?

At SentinelOne, you will be a part of a team of globally distributed system and kernel developers who work deeply within the 3 main OS’s of the world: Windows, Linux, macOS - and create our flagship productline Endpoint Protection, recognized 5x in-a-row as Gartner Leader.

In our macOS team, we are responsible for researching and identifying emerging threats/issues and providing appropriate responses. We also work closely with Product, Support, Sales (in order to win multi-million dollar deals), other R&D engineers, and Quality Assurance to ensure any new issues are quickly addressed and then made a part of the ongoing releases.

You will work directly on our macOS core technology, running on millions of endpoints (in different environments, from C-levels to developers) across thousands of enterprise and government clients worldwide. Your role will also involve responding to events that occur in the field, root-causing them, and issuing patches when needed. You will participate in implementation and design decisions around improving agent architecture and new feature development.

What skills and knowledge should you bring?

• Must have: Strong proficiency coding in Objective-C and multiple years of SW engineering experience for macOS (macOS is highly preferred, but iOS cybersecurity SW product development experience would be also considered relevant)
  • Experience level is flexible, Senior/Staff+ engineers are encouraged to apply!
• Experience in systematically root-causing complex OS systems
• Understanding of macOS user space and internals

Advantages:

• Experience developing OS drivers & system extensions or with more than one OS is a plus
• Experience managing escalations or issues requiring highly coordinated efforts to identify service restoration
• Experience with system performance analysis and mitigations, and with large-scale event processing systems
• Cybersecurity experience or exposure to macOS endpoint security platforms
• Swift experience is beneficial but not required
