SDE 1 – Security Engineer
Navi
Navi is hiring an SDE 1 – Security Engineer to strengthen the security of its rapidly growing financial technology platform. This position offers early-career engineers the opportunity to work on application security, penetration testing, API security, automation, and secure software development practices while collaborating closely with engineering teams. Candidates who enjoy identifying vulnerabilities, building security automation, and contributing to secure products used by millions of users will find this role highly rewarding.
Security has become one of the most critical areas in modern fintech, where protecting customer data and preventing vulnerabilities directly impact millions of financial transactions every day. This opportunity at Navi allows engineers to work on real production applications while gaining practical experience in web security, mobile application testing, API protection, and automation. Engineers joining this team will work alongside developers and product teams to build secure systems from the earliest stages of development rather than treating security as an afterthought.
🔐 What You'll Be Working On
As a Security Engineer, your primary responsibility will be identifying weaknesses before attackers do. The role combines manual penetration testing with automation, allowing engineers to continuously improve security testing processes.
You will perform vulnerability assessments across web applications, REST APIs, GraphQL services, Android applications, and iOS applications while validating security findings through manual testing.
Hands-on Application Security Role
After every security assessment, you'll collaborate directly with software developers to explain security risks, reproduce vulnerabilities, and recommend practical remediation strategies.
⚙️ Engineering Exposure
Rather than relying only on automated scanners, this role emphasizes understanding how applications actually work.
You'll regularly work with:
Python Burp Suite OWASP ZAP Postman Nmap MobSF
A major responsibility includes developing Python automation scripts that simplify repetitive security activities such as vulnerability validation, reporting, log analysis, and scanning workflows. Candidates interested in scripting and automation will gain valuable experience that extends beyond traditional penetration testing.
🌐 Security Areas You'll Explore
The engineering team focuses on identifying vulnerabilities that commonly affect modern web and mobile applications, including:
Cross-Site Scripting (XSS)
SQL Injection (SQLi)
Insecure Direct Object References (IDOR)
Broken Authentication
Improper Authorization
API Security Issues
Mobile Application Vulnerabilities
Sensitive Data Exposure
Security Misconfigurations
Understanding why a vulnerability exists is just as valuable as knowing how to exploit it.
The role also involves validating findings from automated SAST and DAST tools to eliminate false positives before reporting issues to development teams.
🤝 Working With Product Teams
Security engineers at Navi work closely with software developers throughout the development lifecycle instead of operating independently.
You'll explain security findings using clear proof-of-concept demonstrations, help developers understand business impact, recommend secure coding practices, and verify fixes before production deployment. This collaborative approach ensures security becomes an integral part of product development.
📈 Skills That Will Help You Succeed
Candidates are expected to have practical understanding of modern web technologies along with strong programming fundamentals.
Helpful technical knowledge includes:
Required Skills | Additional Advantage |
|---|---|
Python Programming | Go or Bash Scripting |
HTTP & HTTPS | GraphQL Security |
TCP/IP Fundamentals | Mobile Reverse Engineering |
DNS Concepts | Cloud Security Basics |
REST APIs | CI/CD Security |
OWASP Top 10 | Secure SDLC |
Knowledge gained through internships, cybersecurity competitions, Capture The Flag (CTF) events, or bug bounty programs will also be valuable for this position.
🚀 Why This Position Stands Out
Unlike many entry-level security positions that primarily involve monitoring dashboards, this opportunity combines offensive security, automation, software engineering, and developer collaboration.
Engineers will gain production-level exposure to secure fintech applications operating at large scale while learning how security integrates into continuous development environments.
