Reporting to the Head of Security, the Staff Security Engineer will be responsible for building and maintaining tools within the Security Team. Their primary duty is to design projects and build them with other security engineers or others across the Engineering Department. A typical day will include focused development work on a current strategic project, and consulting across the Engineering Department on day-to-day matters.

You'll join a highly-distributed team that’s building a paved security path so our team of more than 100 engineers can focus on their core competencies and worry less about security issues. You'll write sustainable, resilient code as part of an engineering organization that values collaboration, trust, and learning. You’ll be part of a team at the heart of CircleCI’s business, responsible for build environments used by thousands of development teams every day.

What You’ll Do:

  • Write and maintain sustainable, high-quality, high-performance code using Clojure and Go.
  • Operate within the Agile delivery model to deliver value incrementally.
  • Maintain security infrastructure using Terraform, Helm and Kubernetes.
  • Partner with Site Reliability Engineering to solve complex operational challenges.
  • Identify and build user-friendly tools to create a paved path for secure development and operations.
  • Participate in the Security Team’s on-call incident rotation and operations work.
  • Balance paranoia with business needs.
  • Generate new ideas, write problem statements, and proactively consult so other engineers understand the security implications of their ongoing work.
  • Interview additional candidates to scale the Security Team.
  • Lead the curriculum development for CircleCI’s Capture The Flag annual security training for all Engineering Department ICs.

What we're looking for:

Starting projects from scratch is invigorating. You have strong opinions on project design that are based on experience. Establishing processes makes you feel comfortable. Finishing projects and keeping them Done is a fundamental value. Mentoring is a primary reason why you love your profession. Learning something new every day is essential to your happiness. You are compassionate and genuinely like people

Does that sound like you? If so, here’s the experience we’d like to see:

  • 5 years of software engineering experience.
  • Security mindset.
  • Strong analytical skills.
  • Excellent communication skills.
  • Calm under high-pressure situations.
  • Web, database, information and/or infrastructure security.
  • Demonstrated ability to lead multiple, complex projects simultaneously.
  • A focus on delivering high-quality code through strong testing practices.
  • Ability to manage customer demands and work with internal stakeholders to solve them.
  • At least three years experience with a functional language such as Clojure, or alternatively Java, Go or Python, with a willingness to learn new languages.
  • Experience working with some mixture of Docker, Kubernetes, Terraform, Helm, and AWS.
