The posting

AppsFlyer’s Security team is looking for a highly skilled and security-savvy Application Security Engineer to lead our product and application security efforts. In this role, you will drive security design, ensure secure coding practices, and validate our services and environments against the highest security standards.

You will work closely with our R&D and Product teams to identify, mitigate, and prevent security risks throughout the software development lifecycle (SDLC). You will own security initiatives, mentor developers on security best practices, and play a key role in shaping the security posture of AppsFlyer’s products.

The ideal candidate is highly motivated, eager to learn, and has a “security by design” mindset. This role provides career growth opportunities, enabling you to deepen your expertise in AppSec, DevSecOps, and cloud security.

What you'll do:

  • Partner with development and product teams to integrate security best practices into the SDLC
  • Lead threat modeling and architecture security reviews to proactively identify and mitigate risks
  • Conduct security assessments, including code reviews, vulnerability scans, penetration testing, and secure product design reviews
  • Stay up to date with emerging security threats, vulnerabilities, and industry trends, ensuring AppsFlyer remains ahead of evolving risks.
  • Support and contribute to security incident response activities, including root cause analysis and post-incident improvements
  • Automate security processes and integrate security tools within CI/CD pipelines
  • Develop and deliver secure coding training to engineering teams

What you have:

  • 3+ years of experience in Application Security, Penetration Testing, or Product Security in a SaaS company
  • Deep understanding and hands-on experience of web application security, including OWASP Top 10, authentication, encryption, and secure coding principles
  • Proficiency in scripting or programming languages (Terraform, Python, JavaScript, Go, etc.) for security automation and infrastructure.
  • Experience with cloud security best practices (AWS, GCP, or Azure)
  • Strong communication skills, with the ability to explain security risks and recommendations to technical and non-technical stakeholders, including executive management
  • Experience working with large-scale, complex R&D environments

Bonus Points:

  • Hands-on experience with DevSecOps and integrating security tools into CI/CD pipelines
  • Bachelor's degree in Computer Science, Information Security, or a related field (or equivalent experience)
  • Being introduced by an AppsFlyer team member

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
