About the Role

Purple Team Engineer, Linux Endpoint Product Security

Do you tear apart kernel code for fun? Have opinions about eBPF? Know when Ring 3 won’t cut it? Get frustrated at orgs with security programs that are just running tools and handing over reports? Ever want to team up with developers to improve designs and fix vulns? Then we’d like to meet you.

Our team is growing, and we’re looking for capable security people to dig deep into our Linux endpoint products (that enable trillion-event-per-day visibility into our customer’s threat landscape), find design and implementation flaws, and help our product engineers fix problems and ship secure code. If you like to rip apart Linux kernel-mode applications to see how they work and find security flaws; if you want to actually play a part in fixing flaws rather than just reporting them and hoping for the best – we want to hear from you!

In this job, you’ll:

Join project teams working on product improvements and new products as a security expert and advisor, influencing the design and capabilities of our world-class endpoint protection products, with a focus on Linux endpoint sensors
Create and update threat models to help drive security decisions
Read and review source code for applications, looking for security flaws and vulnerabilities; you’ll have tools to help you but you’ll be digging deeper than tools can
Think like a hacker and attack endpoint applications with Ring 1 components, mostly before they go to production; again, you’ll have tools to help you, but you’ll do more than tools can
Work with developers to help them understand problems, risks, design weaknesses, etc. and figure out good solutions
Build small tools and automation to make your life/your team’s life/developers’ lives easier
Validate and replicate some kinds of bug bounty reports, and hunt for similar issues in affected applications

We’re hiring this role at multiple levels, so we still want to hear from you even if you think you can’t do all of that – or if you can do more!

Skills you’ll need:

Experience programming in or assessing security of C/C++ apps for Linux
- Understanding of system internals and kernel security features for Linux
- Comfort with concurrency considerations in multi-threaded applications
Understand the security implications of containerization and virtualization
A working understanding of how software products are created and shipped in Agile/DevOps like environments – enough to have a positive working relationship with product engineers (software product development experience is a huge plus, but not a requirement)
A solid understanding of common software weaknesses that impact endpoint and client/server applications; you’ll be hunting for these, you need to know them when you see them and be able to help product engineers understand and fix them
Comfort with collaborating across technical teams: asking technical questions, challenging assumptions, getting or providing context for decisions, etc.

Bonus skills:

These skills are not required and/or we’re willing to teach them, but they are helpful:

Rust or Go (Golang) programming/review
Experience with debuggers like Ghidra, IDA Pro, or other similar tools
Systems understanding of other Unix-like environments (esp. Mac or Android)
Experience developing/maintaining automation for application security tasks
Experience developing and using threat models, especially using STRIDE
Application penetration testing experience, especially if it includes testing against install packages and control bypass methods
Reverse-engineering or malware analysis, or related security research capabilities
