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.

Key Responsibilities

• 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.

Qualifications

Required Qualifications

• 7+ 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 postmortem 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.

Preferred Qualifications

• 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.

• Proven experience championing DevSecOps within a product organization. You have lived on the security-engineering side of the house, successfully acting as a bridge between development, operations, and security to embed a 'secure-by-design' culture without sacrificing agility.
