Site reliability engineering:

Run, monitor, and maintain a range of custom built, open source, and paid security systems spanning on-premise and cloud infrastructure. Examples include ElasticSearch (ELK) stack, OpenCTI, Fleetdm, Hashicorp Vault, custom-built agentic systems. Respond to production incidents impacting security systems that run on both Kubernetes and bare metal servers.

• Deep understanding of SRE best practices (i.e., Google SRE Books).
• Strong computer science fundamentals (computer architecture, operating systems concepts).
• Ability to produce, understand, and analyze code in at least one popular programming language without assistance.
• Ability to heavily leverage LLMs in your daily work, while maintaining a strong understanding of the output, as well as potential pitfalls.
• Effective verbal and written communication skills.
• Cybersecurity experience is a plus but not required.

Soft Skills:

• Interest in cybersecurity.
• Ability to influence without authority to drive security best practices.
• Organizational skills to manage multiple complex tasks effectively.
• Perseverance in continuously improving security systems and tackling challenges.

Team Structure and Reporting:

• The security group consists of approximately 30 members, divided into 4 teams: a compliance team, a Yellow team, a Blue team, and an Identity & Access Management team.
• This position will report to the Yellow Team Dev Lead.
• The yellow team’s mission is to design and build long-term security systems, promote security by design, and contribute to it in software engineering efforts across the company.
