Job Overview

Job Title: Backend Security Engineer
Job Type: Contractor
Work Arrangement: Remote
Hours: Approximately 15 hours per week
Schedule: Flexible — choose your preferred working days and hours
Compensation: $30–$100/hr

This opportunity is particularly suited to backend engineers who are comfortable working with multiple programming languages and have experience with debugging, performance optimization, security reviews, and large codebases.

What Will You Do?

The role involves contributing your technical knowledge to projects focused on training and improving next-generation AI systems.

Instead of simply writing conventional backend code, you may work on realistic coding challenges that help AI systems better understand programming, debugging, implementation, and software engineering.

Your responsibilities may include:

• Creating realistic and challenging coding tasks

• Implementing new backend features

• Finding and fixing software bugs

• Building deterministic verifiers for coding tasks

• Reviewing solutions against technical requirements

• Refactoring existing codebases

• Improving application and system performance

• Working with algorithms and data structures

• Reviewing code for quality and security

• Applying secure coding practices

• Performing security-focused analysis where required

The work is designed around practical engineering knowledge, so your existing backend and security experience is an important part of the role.

Required Skills

Candidates should have experience with backend development and strong programming fundamentals.

Some of the relevant skills include:

• Python 3

• Java

• Rust

• C++

• TypeScript

• Algorithms and data structures

• Bug fixing

• Feature implementation

• Codebase refactoring

• Performance optimization

• Penetration testing

• Security auditing

Experience with additional backend technologies can also be useful.

Who Is This Opportunity For?

This role may be a good fit for backend engineers who enjoy solving technical problems and working independently.

You may be particularly suited to the opportunity if you have experience with:

• Building scalable backend services and APIs

• Debugging complex applications

• Automated testing

• Performance optimization

• Large-scale codebases

• Code reviews

• Secure software development

• Application security

• Penetration testing

• Vulnerability assessment

• Security-focused code reviews

A cybersecurity or SecOps background is considered a strong advantage, especially if you have worked with areas such as OWASP, CWE, application security, secure coding, or vulnerability assessment.

Preferred Qualifications

The opportunity is looking for professionals who can demonstrate practical experience rather than just theoretical knowledge.

Preferred qualifications include:

• Proven backend development experience

• Experience delivering reliable and performant software

• Knowledge of cybersecurity and secure development practices

• Experience identifying and resolving bugs

• Understanding of system bottlenecks and performance issues

• Experience refactoring existing code

• Ability to implement complex features

• Strong understanding of algorithms and data structures

• Solid computer science fundamentals

• Strong analytical and problem-solving skills

• Good technical communication abilities

Do You Need AI Experience?

No previous AI experience is required.

The opportunity is primarily focused on your existing technical expertise. Your backend development and cybersecurity knowledge can be applied to creating high-quality technical tasks and solutions that help train AI systems.

This makes the role potentially interesting for experienced software engineers who want to explore AI-related work without needing to come from a traditional AI or machine-learning background.

How Does the Selection Process Work?

Applicants can expect several stages during the hiring process.

The general process includes:

1. Submit an application
Complete the application and answer the required screening questions.

2. AI Interview
Complete an AI-based interview that takes approximately 30 minutes.

3. Technical Assessment
A technical assessment may be required depending on the role and project.

4. Hiring Manager Review
Applications and assessment results are reviewed before a final decision is made.

The assessment process is intended to evaluate your own technical reasoning and problem-solving ability. Applicants are expected to complete the interview and assessment independently.

Compensation Structure

The listed compensation range is $30–$100 per hour.

However, compensation is described as output-based, meaning experts are paid according to tasks that meet the applicable project specifications.

The amount of time required to complete a task can vary based on the individual's experience and workflow. Minimum submission requirements may also apply, including a minimum number of tasks that need to be submitted each week.

Because of this structure, the advertised hourly range should not necessarily be interpreted as a guaranteed hourly wage for every hour worked.

Flexible Remote Schedule

One of the notable features of this opportunity is the flexible schedule.

The position is remote, and experts can generally choose the days and hours that work best for them. Weekend availability can also be selected if preferred.

The role is expected to require around 15 hours per week, making it potentially suitable for experienced professionals looking for flexible contract work.

When Can You Start?

The hiring process is designed to move relatively quickly.

The opportunity indicates that roles are typically filled within approximately 48 hours, with selected candidates expected to begin their first tasks within 24–48 hours after completing onboarding.

If you're selected, being ready to start quickly will therefore be important.
