Principal Engineer Software, AppSec; Chronosphere

Job Summary

As a hands‑on Security Engineer, you will play a crucial role within the infrastructure engineering team. Your responsibilities include defining and building core security engineering efforts to create a foundational security infrastructure used across the entire company. Success in this role requires leveraging a deep understanding of security infrastructure, strong system software development skills, and empathy for other developers. Your goal is to ensure security serves as a shared guardrail, never a bottleneck, regardless of the project.

• Design, implement, and work with other engineering teams to operate security tools and programs across the organization, including access control & workflows, vulnerability management, and detection/response systems.
• Collaborate with other engineers and with the business to identify the highest priority needs of the organization, and maintain a roadmap to address those needs.
• Actively participate in design reviews, threat modeling, and incident analysis.
• Help teams make high‑quality security decisions, especially in ambiguous situations.
• Set the bar for security, ownership, and quality across engineering.

• 10+ years in security or infra‑focused engineering roles with meaningful security ownership.
• The ability to independently own projects from inception to delivery.
• A systematic problem‑solving approach, coupled with strong communication skills and a sense of ownership and drive.
• Empathy for the problems faced by developers, and a passion for building tools and systems that address those problems.
• Built vulnerability management systems that actually drive risk down.
• Led security incident response efforts and post‑mortem improvements.
• Strong interest in how things work. Curiosity and persistence is key to building the understanding needed to apply.
• A flexible, collaborative working style. We’re a small team working in a rapidly evolving space, and we’re looking for people who will help build a positive, supportive environment.
• 3+ years of experience building infrastructure software in Go or Python.

• Experience building foundational security programs at growth‑stage companies.
• Familiarity with compliance frameworks, but a healthy skepticism of security theater.
• An outstanding ability to communicate risk with both technical and non‑technical audiences.
• Experience working with C++ or Rust.
