## Job description

### About the Position

Ox Security secures the AI-driven SDLC from prompt to production. We eliminate critical, real-time risks from AI code generation through cloud runtime by doing what conventional tools can’t: unifying development and cloud context to stop vulnerabilities right at the source. At OX, we’re building the future of cyber security for the AI era. If you’re looking to work on disruptive technology with an amazing team, you belong here.

We’re growing fast and looking for a Senior Backend Engineer to join our Engineering team and help build the infrastructure that powers our platform at scale.

This is a high-impact role where you’ll work alongside top-tier engineers, designing and building secure, high-performance systems in a fast-paced environment. If you enjoy solving complex technical challenges and want your work to have real impact - we’d love to meet you.

### Responsibilities

### What You’ll Be Doing

- Design and implement scalable backend systems and APIs

- Collaborate with Product, Frontend, and other engineering teams on system architecture and requirements

- Optimize performance, scalability, and security of applications

- Troubleshoot and resolve production issues with minimal downtime

- Lead code reviews and promote best engineering practices

- Mentor and support junior engineers

- Continuously improve system design, reliability, and development processes

### Requirements

### What We’re Looking For

- Bachelor’s degree in Computer Science or a related field

- 5+ years of experience in backend development

- AI-First Approach – Active and proficient use of AI tools (e.g., Copilot, LLMs) to streamline coding practices, accelerate learning curves, and optimize workflows.

- Strong experience building scalable, production-grade systems

- Proficiency in Node.js

- Experience with SQL and NoSQL databases

- Familiarity with cloud platforms and microservices architecture

- Strong problem-solving skills and attention to detail

- Passion for writing clean, maintainable, and efficient code

### Bonus Points for :

- Experience in the cybersecurity, SaaS, or Cloud Security domain.

- Hands-on experience with modern cloud environments (AWS/GCP), Docker, and Kubernetes.

### Employment & Benefits Package (via Commit)

We partner with Commit offshore, who acts as our official local Employer of Record, to manage payroll, local compliance, and provide top-tier benefits for our Argentina-based team members:

- USD-Based Salary: Receive your salary directly in USD, with full flexibility to manage your funds and convert to local currency on your own terms.

- 100% Remote: Full-time position based anywhere in Argentina, requiring standard daily availability and reasonable working hours overlap with our Israel and EU teams.

- Paid Time Off (PTO): 20 Days Annual Leave & 5 Sick Days to support your health and work-life balance.

- Gifts & Events: Gifts on your birthday & Holidays along with company events to keep you connected and appreciated.

**Live in Ox Security’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
