Junior Reverse Engineer (Hybrid - Barcelona)

00066789593

What makes Cognizant a truly unique place to work?

Cognizant offers strong growth, global reach and an innovative environment where tech professionals can deliver meaningful, high‑impact work. Teams collaborate across regions to build and deliver advanced solutions for leading companies, enabling greater agility, innovation and performance.

We are seeking a motivated Junior Reverse Engineer to join our team. You will perform essential static and dynamic analysis on Android applications, focusing on the functionality and usage of our SDK. This role provides a structured environment where you will gain hands-on experience with industry-leading tools and methodologies. While expected to strive for independent resolution, an established escalation path is in place to support your growth in handling complex, low-level challenges.

This is an excellent opportunity to begin a career in mobile security and reverse engineering, where you can develop skills to handle complex technical challenges.

Can you see yourself in this position? Check the requirements and apply!

Key Responsibilities:

  • Conduct static and dynamic analysis of Android applications (APKs) to understand functionality and application logic.
  • Execute reverse engineering tasks within established, easier-to-moderate complexity workflows.
  • Identify, analyze, and document potential malicious or non-compliant SDK usage through analysis.
  • Attempt independent resolution on all assigned analysis tasks; recognize complex anti-analysis, highly obfuscated, or native code challenges and document them clearly for escalation to Mid/Senior Engineers.
  • Utilize tools such as Apktool, Frida, Ghidra, Hexdump, and Burp Suite for daily tasks.
  • Collaborate with senior members to communicate findings and learn mitigation strategies.

You are someone who brings:

  • Expertise in Android operating system architecture and application development lifecycle.
  • Strong analytical and problem-solving skills.
  • Ability to work independently and as part of a team.
  • Good analytical, problem-solving, and documentation skills.

What we Offer:

At Cognizant, you will have the opportunity to work on diverse projects and engage with the latest industry technologies. We are committed to creating excellent workplace experience, offering a competitive base salary and a comprehensive range of benefits, including:

  • A comprehensive total rewards package, including a competitive salary and a pension plan with matching contributions.
