About The Role

We are seeking a motivated Junior Security Engineer to join our Security team in Jakarta, Indonesia.

You will support the team in identifying vulnerabilities across our infrastructure and applications, learning to provide clear remediation advice, and helping to build a more resilient organization.

What You Will Do

• Conduct vulnerability assessments and penetration tests across web, mobile (iOS/Android), and network environments.

• Drafting penetration test reports that detail findings, risk levels, and step-by-step reproduction instructions.

• Collaborate with developers to help them understand security findings and verify that fixes have been correctly implemented.

• Keep up with the latest CVEs, OWASP updates, and security research to bring fresh perspectives to the team.

What Are We Looking For

• A strong understanding of networking (TCP/IP), web technologies (HTTP/HTTPS), and basic OS security (Linux/Windows).

• Familiarity with the OWASP Top 10 and common vulnerability classes (SQLi, XSS, Broken Auth).

• OSCP is highly preferred, but we will consider candidates with eJPT, PNPT, or CEHP, provided they show a strong desire to obtain their OSCP within the first year.

• Basic experience with tools like Burp Suite (Community/Pro), Nmap, and SQLmap.

• Ability to follow a testing methodology and document technical steps clearly.

• Preferred but not required: have experience or be interested in smart contract audit.
