Identifying and fixing security vulnerabilities

Preferred Qualifications

Experience working on large-scale or production-grade applications.
Experience implementing complex features in existing codebases.
Experience with software refactoring and performance optimization.
Strong experience identifying software bugs, bottlenecks, and edge cases.
Experience designing robust automated test suites.
Experience reviewing or evaluating code written by other engineers.
Cybersecurity, AppSec, or penetration-testing background.
Strong analytical and problem-solving abilities.
Ability to understand unfamiliar codebases quickly.

Who Should Apply

This opportunity may be a good fit for:

Backend Software Engineers
Senior Software Engineers
Full-Stack Engineers with strong backend experience
Software Developers
API/Platform Engineers
Application Security Engineers
Security Engineers with strong programming skills
DevSecOps Engineers
Cybersecurity Engineers with software development experience

Important Note About the Assessment

Our interview and assessment process is designed to evaluate your individual technical reasoning and problem-solving ability.

Selection Process

Apply for the role and complete the screening questions.
Complete an AI-based interview — approximately 30 minutes.
Complete a technical assessment, if applicable.
Hiring Manager review.
Selected candidates complete onboarding and begin project work.

Compensation

Compensation is output-based. Experts are paid per completed task that meets the applicable project specifications and quality requirements.

The time required to complete a task may vary depending on the complexity of the task, experience level, and individual workflow.

Minimum submission requirements may apply, including a minimum number of completed tasks per week.

Start Timeline & Availability

We are looking for engineers who can start quickly.

Selected candidates should be prepared to begin their first tasks within 24–48 hours after completing onboarding.
