Member of Technical Staff, Security Engineer

Security Engineer

As a Security Engineer at Crosby, you'll play a critical role in designing and implementing the security foundations of our platform. You'll be responsible for protecting sensitive legal data, securing our infrastructure, and embedding best-in-class security practices across the engineering organization.

You'll work closely with engineering, product, and legal teams to identify risks, implement controls, and ensure our systems meet the highest standards of security and compliance. This role is for someone who is both deeply technical and highly pragmatic — able to balance strong security guarantees with the speed required in a fast-moving environment.

Responsibilities

1. Own application and infrastructure security: Design and implement security controls across our application, APIs, and cloud infrastructure.

2. Protect sensitive data: Build systems and processes to safeguard confidential legal and customer data.

3. Drive security best practices: Establish and enforce secure development practices, including code reviews, threat modeling, and vulnerability management.

4. Monitor and respond: Implement monitoring, alerting, and incident response processes to detect and respond to security threats.

5. Ensure compliance readiness: Support security and compliance efforts (e.g., SOC 2), including documentation, controls, and audits.

6. Collaborate across teams: Partner with engineering and product teams to embed security into the development lifecycle without slowing velocity.

Who You Are

2. Strong understanding of application security, cloud security (e.g., AWS/GCP), and common vulnerability classes

3. Experience securing production systems, including authentication, authorization, and data protection

4. Proficient in at least one programming language (e.g., Python, Go) and comfortable working with engineering teams

5. Experience with security tooling, monitoring systems, and incident response workflows

6. Highly pragmatic — able to prioritize risks and implement effective, scalable solutions
