Web & API Security Engineer

Axos Business Center, Corp

About This Job
We're seeking a highly skilled Web & API Security Engineer with deep offensive security expertise. This is a hands-on role focused on identifying and exploiting vulnerabilities in modern web applications and APIs. You'll simulate real-world attacks, uncover complex flaws, and collaborate directly with engineering teams to strengthen our platform's defenses. If you thrive on manual testing, creative problem-solving, and thinking like an adversary, this role is built for you.

As a Web & API Security Engineer, you will:

• Conduct manual security testing of production-grade web apps and APIs (REST, GraphQL, gRPC)
• Identify advanced vulnerabilities beyond standard CVEs — including logic flaws, authentication bypasses, and chained exploits
• Simulate adversarial behavior and design attack paths that mimic real-world threat actors
• Analyze and exploit security controls such as WAFs, rate limits, and token-based auth systems
• Document findings clearly for engineering teams, enabling fast and effective remediation
• Explore edge cases and abuse scenarios that automated tools often miss

You'll have full autonomy over your testing strategy, tools, and targets — and your work will directly impact the security of our platform.

Qualifications:

• Proven experience in manual penetration testing of web applications and APIs
• Deep understanding of HTTP, cookies, sessions, JWTs, CORS, and authentication flows
• Expertise in AuthN/AuthZ vulnerabilities (e.g., OAuth abuse, IDOR, BOLA, SSO bypass)
• Familiarity with API attack vectors such as schema enforcement issues, replay attacks, and parameter pollution
• Proficiency with tools like Burp Suite Pro, Postman, ffuf, sqlmap, jwt_tool, mitmproxy, and scripting in Python or Bash
• Strong threat modeling mindset — you think in terms of abuse cases, not just known vulnerabilities

Ideal Traits:

• Operates independently with a red team mindset
• Demonstrates extreme ownership and attention to detail
• Thrives in a fast-paced, high-accountability environment
• Passionate about security and driven to uncover the unexpected
